HullStack House Terms of Service

Document set: core · Type: tos Applies to: every HullStack fleet app that adopts these house terms, together with that app's Per-App Addendum, which together form the complete Terms of Service for that app.

0. How this document works; order of precedence

These House Terms are shared across every app in the HullStack fleet (e.g. Hundredfold Home, and any app that authenticates through Hundredfold Home's OIDC identity provider). Each app additionally publishes a short Per-App Addendum (see addendum-template.md) covering anything specific to that app — the services it provides, app-specific data collection, billing, and so on. The applicable app's Addendum is incorporated into these Terms by reference and, together with these House Terms, forms "these Terms." The Addendum is not merely linked for reference: it is presented for acceptance in the same consent flow as these House Terms and the Privacy Policy (see §1), so that any app-specific term it contains is covered by the same recorded acceptance. Our House Privacy Policy describes how we handle your information and is likewise incorporated into these Terms by reference.

Order of precedence. If a provision of these House Terms conflicts with a provision of an app's Addendum, then, to the extent of the conflict and unless the Addendum expressly and specifically names and overrides a numbered House Terms section:

1. the Addendum controls for app-specific operational matters — the features and description of that app's Service, the categories of data it collects, device permissions, third-party processors, and billing; and
2. the House Terms control for the core legal mechanisms — Electronic Records and Signatures (§2), Eligibility and Children (§4), Dispute Resolution / Arbitration (§18), Governing Law and Forum (§19), Disclaimers (§15), Limitation of Liability (§16), Indemnification (§17), and Changes / No Retroactive Changes (§20–§21).

An Addendum can override a numbered House Terms section only by express and specific reference to that section — never silently.

1. Acceptance of Terms

By creating an account, or by clicking/tapping an "I agree" (or equivalently assent-worded) button presented alongside these Terms — these House Terms, the applicable app's Addendum, and the Privacy Policy, presented together as the document set you are asked to accept (§0) — you agree to be bound by these Terms. If you do not agree, do not create an account or use the service ("Service").

Acceptance is recorded as an explicit, timestamped, append-only event (see consent_acceptances in the Hundredfold Home consent ledger) — an immutable record of exactly which version of these Terms you accepted, when, and how (clickwrap: an assent-worded control with tappable links to the current Terms, Privacy Policy, and Addendum in proximity). We do not require you to scroll the full concatenated text before agreeing. We do not treat silence, inactivity, or mere continued use as acceptance of these Terms or of any change to them (see §20).

Each app is a separate acceptance. These Terms are registered and accepted per app (each under that app's own app_id). Accepting these Terms for one app is not acceptance for any other app, even where the house text is identical — see §6 (Shared Sign-In and Multi-App Use).

2. Electronic Records and Signatures

Because the Service is delivered electronically, these Terms, the Privacy Policy, the applicable Addendum, and all notices, disclosures, and records relating to them are provided to you in electronic form, and your electronic acceptance (a click/tap on an assent-worded control, recorded in the consent ledger described in §1) has the same legal effect as a handwritten signature. By accepting, you consent to transact electronically and to receive records electronically, consistent with the E-SIGN Act (15 U.S.C. §7001 et seq.) and applicable state UETA law.

To access and retain these electronic records you need a device with a current web browser or a current version of the app, an internet connection, and the ability to view and save PDF or HTML documents. You may withdraw your consent to transact electronically, or request a paper copy of any record, by contacting us as described in §23; because the Service is delivered electronically, withdrawing that consent means you can no longer use the Service.

3. Definitions

Capitalized terms have the meanings given where first defined; the principal ones are collected here so they are defined before use:

• "Service" — the applicable HullStack fleet app and its features, as described in that app's Addendum (§5).
• "we," "us," "our" — Field's Edge Software LLC, the entity operating the Service described in these Terms. The same entity is the "data controller" referenced in the Privacy Policy. Today, Field's Edge Software LLC operates both the Hundredfold Home OIDC identity provider and every app that adopts these House Terms — see §6. If a future fleet app is operated by a different legal entity, that app's Terms will identify that entity as the party you contract with for that app.
• "you," "your" — the Household Adult (§4.1) who accepts these Terms and the account holder(s) covered by that acceptance.
• "User Content" — content you submit to the Service (§9).
• "Household Adult" (also "Parent/Guardian") — an eligible adult who creates and administers a household account (§4.1).
• "Child Account" — an account for a child in a household, provisioned and administered by a Household Adult (§4.2).
• "House Documents" — these House Terms together with the House Privacy Policy.

4. Eligibility; Household Accounts; Children

4.1 Who may contract

You must be at least 18 years old — or the age of majority in your jurisdiction, if higher — to create an account and accept these Terms in your own right ("Parent/Guardian" or "Household Adult"). You represent that you have the legal capacity to enter into these Terms.

4.2 Household accounts and children — children are never the contracting party

The Service supports household accounts, where a Household Adult may create and administer accounts for children in their household ("Child Accounts"). A Child Account is never itself party to these Terms:

• Only a Household Adult can accept these Terms, and does so on behalf of the household, including any Child Accounts within it, through an explicit relationship affirmation presented as part of acceptance — substantially: "I am the parent or legal guardian of [Child Account name(s)]. I accept these Terms on their behalf and am responsible for their use of the Service." Acceptance captures the accepting adult's identity, the specific Child Accounts covered, and this stated relationship — this is recorded, not merely asserted in passing. This affirmation is the contract consent under these Terms — the act that binds the household to this agreement. It is a separate thing from any verifiable-parental-consent obligation that may independently apply to the collection of a child's personal information under COPPA — see §4.3.
• A Child Account cannot itself click/tap to accept these Terms, and any session authenticated as a Child Account is barred from doing so at the system level, not merely as a matter of policy.
• The Household Adult who accepts represents that they have the authority to bind the household and to consent on behalf of each covered Child Account, is responsible for that Child Account's compliance with these Terms, and is responsible for supervising that Child Account's use of the Service, to the extent required by applicable law and as further described in the Service's parental-controls documentation. This affirmation binds the accepting adult's own obligations and responsibility for the Child Account's use — it does not purport to waive, release, or otherwise limit any claim or right the child may independently hold under applicable law. A parent/guardian's acceptance on a household's behalf is not read to surrender the child's own rights or claims, consistent with the limits courts have placed on a parent's authority to bind a child to terms, or waive a child's own claims, that the child never personally assented to.

4.3 Children's Online Privacy Protection Act (COPPA) — United States

COPPA's verifiable-parental-consent (VPC) requirement attaches to the collection of a child's personal information, not to acceptance of these Terms as such — the two are treated as separate consents in this design, even though both currently happen through the same Household Adult. The Service captures a Household Adult's attestation (the relationship affirmation described in §4.2: "I am the parent or legal guardian of… I accept on their behalf and am responsible for their use") as its verifiable parental consent for the personal information collected to create and operate a Child Account. The consent architecture is pluggable: it can require a stronger verifiable-consent method (e.g. one of the FTC's other approved VPC mechanisms) for a specific feature or data-collection trigger in the future, but no such stronger method is presently required — attestation is the sole VPC mechanism in effect today.

In addition:

• A Child Account is provisioned exclusively by a Household Adult, who provides the consent required to create it (a Household Adult act, not data collected from the child).
• We do not knowingly collect personal information directly from a child under 13 outside of a Household Adult-provisioned Child Account, and we do not require a child to disclose more personal information than is reasonably necessary to participate in a Service activity.
• A Household Adult may review, request deletion of, or refuse further collection of a child's personal information by contacting us as described in §23, subject to the technical and legal limits on deleting an append-only record described in our House Privacy Policy.

Read this section together with House Privacy Policy §3, which describes the same practices from the privacy side.

5. The Service

The Service is described in the applicable app's Per-App Addendum. We may add, change, or discontinue features of the Service at our discretion, subject to §20 for changes that also require a change to these Terms. We may impose reasonable limits on use of the Service (e.g. rate limits, storage limits) and may set, and change, such limits.

6. Shared Sign-In and Multi-App Use (OIDC)

Hundredfold Home acts as an OpenID Connect (OIDC) identity provider, so a single set of sign-in credentials may let you access more than one HullStack fleet app. For clarity:

• Signing in to a second app using your Hundredfold Home identity does not by itself constitute acceptance of that second app's Terms. Each app presents, and separately records, its own acceptance (§1); each app's Terms = these House Terms as registered for that app plus that app's Addendum. An app that relies on Hundredfold Home for login but has not presented and recorded its own acceptance has no acceptance record for you — there is no shared or fleet-wide acceptance.
• Today, every HullStack fleet app — including the Hundredfold Home OIDC identity provider itself — is operated by the same contracting entity, Field's Edge Software LLC (§3). If a future fleet app is operated by a different legal entity, the entity identified in that app's Terms is the party you contract with for that app instead.
• Your Hundredfold Home account credentials are governed by §7 across every app you use them with.

7. Accounts and Security

You are responsible for maintaining the confidentiality of your credentials and for all activity under your account. Where the Service uses a login code as a child's credential, that code is the child's only credential; a Household Adult controls it, and can reissue or revoke it (which also re-keys the child's encryption keys — see §10). Do not share credentials, and notify us promptly, using the contact method in §23, of any actual or suspected unauthorized use of, or loss of control over, your credentials or account. We are not liable for loss arising from unauthorized use of your account that results from your failure to safeguard your credentials, to the extent permitted by applicable law.

8. Acceptable Use

You agree not to, and not to permit any account within your household to (an app may add to this list in its Addendum §F):

• use the Service in violation of any applicable law or regulation, or to facilitate any unlawful act;
• upload, transmit, or store content that is unlawful, or that infringes or misappropriates a third party's intellectual-property, privacy, or other rights;
• use the Service to harass, threaten, exploit, endanger, or harm a minor, or to produce, store, or transmit child sexual abuse material (CSAM) or other content that sexually exploits a minor;
• impersonate any person or entity, or misrepresent your affiliation or your relationship to a Child Account;
• interfere with, disrupt, probe, or attempt to gain unauthorized access to the Service, its security, other users' accounts, or its infrastructure;
• circumvent, disable, or defeat any access control, rate limit, usage limit, or security feature;
• scrape, harvest, or perform automated bulk extraction of data outside a published, authorized API, or use the Service to build a competing service in violation of applicable law;
• transmit malware, or use the Service to send spam or other unauthorized bulk or commercial communications;
• reverse engineer, decompile, or attempt to derive source code or keys from the Service except to the extent applicable law expressly permits.

How these rules are enforced against encrypted content. Because certain content is end-to-end encrypted and technically unreadable by us (§10), we cannot proactively detect a violation that occurs within E2EE content. Enforcement there necessarily depends on a report from a participant in the conversation, or from a Household Adult with access to a Child Account's content through the recovery mechanism in §10.3. Nothing in §8 obliges us to monitor content we are cryptographically unable to read.

9. User Content and License

You retain ownership of content you submit to the Service ("User Content"). You grant us a limited, non-exclusive, worldwide, royalty-free license to host, store, transmit, back up, and display User Content solely as necessary to operate the Service for you and those you choose to share it with (e.g. household or conversation members), and to make technical copies (e.g. encryption, transmission, caching, backup) required to do so. This license ends when the User Content is deleted from the Service, except for copies retained transiently in backups and for the append-only records described in the Privacy Policy, and except to the extent you have shared User Content with others who retain their own copy.

Scope limited by encryption. For User Content that is end-to-end encrypted (§10), this license does not and cannot grant us any ability to read, analyze, use, or disclose the plaintext of that content — we do not hold the keys and are cryptographically unable to access it. The license grant is not a representation that we can access encrypted User Content; it exists only to authorize the ciphertext handling (storage, transmission, backup) the Service performs on your behalf.

You represent that you have the rights necessary to submit your User Content and to grant this license, and that your User Content does not violate §8.

10. End-to-End Encryption; Zero-Knowledge Limits; Household Key Recovery

For any app or feature that offers end-to-end encryption (E2EE), we want to be precise about what that protects and — importantly — what it does not.

10.1 What E2EE protects

The body/content of E2EE communications and content is encrypted on your device and can be decrypted only by the intended recipients' devices. We store that content only as ciphertext and cannot read its plaintext: we do not hold your content-encryption keys, and we are cryptographically unable to decrypt, search, scan, moderate, hand over in plaintext, or otherwise access the content of E2EE material.

10.2 What E2EE does NOT protect (metadata)

E2EE protects content, not metadata. To operate the Service, we necessarily process information about your communications and content that is not itself E2EE — for example, the existence of a message or item, its participants/recipients, timestamps, ordering, approximate sizes, delivery and read state, and the account/household/device technical information described in the Privacy Policy. Do not assume that "end-to-end encrypted" means we can see nothing; it means we cannot see the encrypted content.

10.3 Household key recovery for Child Accounts (READ THIS)

This is a deliberate design choice specific to a family-safety product, and it is an intentional exception to "only the participants can decrypt." So a parent is never permanently locked out of a child's account or content:

• A Child Account's private key is escrowed (stored in encrypted form) to every household administrator when the Child Account is created or re-keyed. This means a household administrator can recover a Child Account's private key and can therefore decrypt that Child Account's end-to-end-encrypted content. This is intentional.
• We store these escrow envelopes on our servers, but they are encrypted such that only a household administrator (not we) can open them — we remain unable to read the child's key or content ourselves.
• Issuing a child's login code re-wraps the escrowed key so that redeeming the code unlocks the child's encryption without a password; reissuing/re-keying a child's code mints a fresh key, revokes the child's sessions and prior code, and re-escrows the new key to the administrators.
• Adult accounts are different. Only Child Account keys are escrowed. A Household Adult's private key is not escrowed to anyone, and there is no comparable recovery path for adult-to-adult E2EE content — by us or by another household member.

If you are (or administer) a Child Account, you should understand that the household's administrators can access that account's E2EE content through this mechanism.

10.4 Consequence: we may be unable to recover content for you

Because we cannot decrypt E2EE content, if all key-holders for a given item lose access to their keys (and, for a Child Account, no household administrator can recover the escrowed key), that content may be permanently unrecoverable, including by us. We are not liable for such loss, to the extent permitted by applicable law.

10.5 Non-E2EE household data — no backup promise, no SLA

Some household-authored content is not end-to-end encrypted (the applicable app's Addendum lists which surfaces are and are not). That data is encrypted in transit and at rest on our servers, but we can read it because the feature needs it (for example, to send a titled reminder, to power an in-app assistant, or to match a shopping list against a pantry). We do not promise backups, snapshots, point-in-time restore, or any availability SLA for that data. It can be lost through hosting failure, operator error, account or household deletion, or termination of the Service (§14). The AS IS / AS AVAILABLE terms in §15 and the limitation of liability in §16 apply to that loss the same way they apply to E2EE content.

11. Intellectual Property

The Service, excluding User Content, and all associated intellectual-property rights, are owned by us (§3) and/or our licensors, and are protected by applicable intellectual-property laws. Except for the rights expressly granted to you in these Terms, we reserve all rights in and to the Service. "Hundredfold Home," and associated names, logos, and marks are our trademarks. Nothing in these Terms grants you any right to use them.

12. Copyright / DMCA Notice-and-Takedown

We respond to notices of alleged copyright infringement concerning content we are technically able to access and act upon, consistent with the U.S. Digital Millennium Copyright Act (DMCA), 17 U.S.C. §512. If you believe content accessible through the Service infringes your copyright, send a notice with the elements required by 17 U.S.C. §512(c)(3) to our designated agent, using the contact method in §23 and marking the notice for the attention of our DMCA agent. We may remove or disable access to allegedly infringing content and may terminate, in appropriate circumstances, the accounts of repeat infringers.

Note on E2EE: we cannot access, and therefore cannot review or remove, the plaintext of end-to-end-encrypted content (§10); the DMCA process necessarily applies only to content we are technically able to act upon.

13. Subscriptions and Billing

If the applicable app offers paid subscriptions, billing terms (price, billing cycle, trial terms, auto-renewal, cancellation, and refund policy) are set out in that app's Per-App Addendum, and are subject to the rules of the platform through which the subscription is sold (e.g. the Apple App Store or Google Play).

Wherever an app enables subscriptions, these house-level rules apply: the price and billing cycle are disclosed to you before you purchase; a subscription renews automatically at the then-current price for the same term until you cancel; you may cancel at any time through the platform account you purchased through, and cancellation takes effect at the end of the current billing period; and refunds are handled under the rules of that platform. Because purchases are processed by the platform store, the store — not we — is the merchant of record and controls refunds and billing disputes.

14. Termination and Suspension

• By you. You may terminate your account at any time through the Service's account-deletion feature or by contacting us.
• By us. We may suspend or terminate your access, in whole or in part, with or without notice, if you materially breach these Terms (including §8), if required to protect the Service, other users, or a minor, if required by law, or as otherwise permitted by these Terms. Where practicable and lawful, we will give notice and, for a curable breach, an opportunity to cure.
• Effect. On termination, your license to use the Service ends and we may delete your account and User Content, subject to the retention and append-only-record limits described in the Privacy Policy. We delete or de-identify account data within 30 days of termination, except for the append-only consent ledger and anything we are required to retain by law. Terminating your account does not by itself entitle you to a refund of a subscription already paid; refunds, if any, are handled by the platform store through which you purchased (§13).
• Survival. Sections that by their nature should survive termination — including §9 (license limits that survive), §11 (Intellectual Property), §15 (Disclaimers), §16 (Limitation of Liability), §17 (Indemnification), §18 (Dispute Resolution), §19 (Governing Law and Forum), §21 (No Retroactive Changes), and §22 (Miscellaneous) — survive termination.

15. Disclaimers

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE, THAT DATA (INCLUDING ENCRYPTED CONTENT — SEE §10) WILL NOT BE LOST, OR THAT DEFECTS WILL BE CORRECTED.

Some jurisdictions do not allow the exclusion of implied warranties or the limitation of statutory consumer rights, so some or all of the above exclusions may not apply to you, and you may have additional rights. Nothing in this section limits any warranty or remedy that cannot be excluded or limited under the law of your home jurisdiction, or any right you have under the rules of the platform store through which you obtained the app.

16. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW:

• NEITHER PARTY WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
• OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (a) THE AMOUNTS YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM AND (b) USD $100.
• Carve-outs. These limits do not apply to liability that cannot be limited or excluded under applicable law — including liability for gross negligence, willful misconduct, fraud, death or personal injury caused by our negligence, or liability under consumer-protection or children's-privacy law that may not be limited by agreement. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above may not apply to you in whole or in part.

17. Indemnification

To the extent permitted by applicable law, you will defend, indemnify, and hold us harmless from third-party claims, and related losses and reasonable attorneys' fees, arising out of (a) your User Content, (b) your breach of §8 (Acceptable Use), or (c) your infringement or misappropriation of a third party's rights — except to the extent the claim arises from our own wrongdoing.

This section does not apply to ordinary personal or household use of the Service consistent with these Terms, and does not apply to the extent applicable consumer-protection law prohibits it. We will promptly notify you of any claim for which we seek indemnity, and you may control the defense and settlement of that claim provided that you may not settle it in a way that imposes any obligation or admission on us without our prior written consent, and we may participate in the defense with counsel of our own choosing at our own expense.

18. Dispute Resolution: Informal Resolution, Binding Arbitration, and Class Action Waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT AND TO HAVE A JURY TRIAL.

18.1 Informal resolution first

Before starting an arbitration or (where permitted) a small-claims action, you and we agree to try to resolve the dispute informally for at least 30 days after written notice of the dispute. Your notice must be sent to us using the contact method in §23 and must describe the dispute and the relief sought; ours will be sent to the contact you have on file. This informal-resolution requirement is a condition precedent to arbitration, and the limitations period is tolled while it runs.

18.2 Agreement to arbitrate

Except for (i) disputes that qualify for and are brought in small-claims court, and (ii) claims seeking only injunctive or equitable relief for intellectual- property infringement or unauthorized access to the Service, you and we agree that any dispute arising out of or relating to these Terms or the Service will be resolved by binding, individual arbitration rather than in court. The arbitration will be administered by a nationally recognized arbitration administrator that regularly administers consumer arbitrations, under that administrator's consumer arbitration rules in effect when the arbitration is filed. We will identify the administrator in our response to your §18.1 notice; if you object to that administrator within 30 days, the parties will agree on another, and failing agreement a court of competent jurisdiction will appoint one. The Federal Arbitration Act governs the interpretation and enforcement of this section.

18.3 Who decides arbitrability

Questions about whether a dispute is subject to arbitration — including the scope, enforceability, or formation of this §18 — are decided by a court, not the arbitrator. These Terms contain no delegation clause.

18.4 Location, procedure, and costs

The arbitration may proceed by written submissions, telephone, or video without an in-person hearing. If an in-person hearing is held, it will take place in the county of your residence unless you and we agree otherwise. Filing, administration, and arbitrator fees are allocated under the administrator's consumer arbitration rules, which generally require us to bear most of those fees for a consumer claim; where those rules would require you to pay a fee that exceeds what you would pay to file the same claim in court, we will pay the difference. Each party otherwise bears its own attorneys' fees, except where a statute or the arbitrator's award provides otherwise.

18.5 Class action and jury trial waiver

You and we each waive the right to a jury trial and to participate in a class action, collective action, or representative action. The arbitrator may not consolidate more than one person's claims and may not otherwise preside over any form of a representative or class proceeding.

If applicable law makes a particular representative claim non-waivable (for example, certain claims under California's Private Attorneys General Act), that claim is severed from the arbitration and may be brought in court, while every other claim between you and us remains subject to arbitration and is stayed pending resolution of the severed claim.

18.6 Opt-out right

You may opt out of this §18 (Dispute Resolution) — without opting out of the rest of these Terms — by sending us written notice within 30 days of your first acceptance of these Terms (for this app), using the contact method in §23 and stating your name, the account, and that you opt out of arbitration. If you opt out, neither you nor we are bound by §18.2–§18.5 for disputes between us. A timely opt-out has no other effect on these Terms.

18.7 Confidentiality; survival

Nothing in this §18 requires you to keep the existence, subject matter, or outcome of a dispute confidential, or prevents you from reporting a dispute to a government agency or from discussing it where the law protects that right. This §18 survives termination of these Terms and of your account.

18.8 Severability of this section

If any part of this §18 is found unenforceable, that part is severed and the rest of §18 remains in force — except that if the class-action waiver in §18.5 is found unenforceable as to a particular claim, that claim (and only that claim) is severed from arbitration and proceeds in court, while every other claim remains subject to arbitration.

19. Governing Law and Forum

These Terms are governed by the laws of the State in which we maintain our principal place of business, as identified in §23, without regard to its conflict-of-laws rules, and (for arbitration) by the Federal Arbitration Act. For any dispute not subject to arbitration under §18 (e.g. small-claims actions or claims for equitable IP/unauthorized-access relief), you and we submit to the exclusive jurisdiction and venue of the state and federal courts located in that State, and each party waives any objection to that forum.

This section does not deprive you of the protection of any mandatory consumer-protection law of your home jurisdiction that cannot be waived by a choice-of-law or forum clause, and does not prevent you from bringing a qualifying claim in the small-claims court of your home jurisdiction.

20. Changes to These Terms

We may revise these Terms from time to time. How a revision takes effect depends on whether it is a material change:

• Material changes (changes that meaningfully affect your rights or obligations — including, without limitation, changes to §18 (Dispute Resolution), §16 (Limitation of Liability), §15 (Disclaimers), or the scope of data we collect) require your affirmative re-acceptance before they apply to you. We will give you conspicuous advance notice of a material change — through the Service (e.g. an in-app notice) and, where we have a Household Adult's email address on file, by email — at least 30 days before the revised version becomes the CURRENT version you are asked to accept. Until you affirmatively re-accept, the version of these Terms you last accepted continues to govern your use of the Service, and continued use of the Service during the notice period is not, by itself, treated as acceptance of the material change. If you never re-accept, the version you last accepted continues to govern indefinitely and we will not terminate your account for that reason alone; the sole exception is a change we are legally required to make, where continuing to serve you under the prior version would be unlawful — in that case we may limit or suspend your access after giving you at least 30 days' further notice and an opportunity to export your data or delete your account. Where the accepting Household Adult's original acceptance was made on behalf of a household, including Child Accounts (§4.2), a required re-acceptance re-captures the on-behalf relationship affirmation and the specific Child Accounts covered at the time of re-acceptance — it is not automatically carried forward from the prior acceptance record. This keeps the on-behalf record current (e.g. if a Child Account has been added, removed, or the accepting adult's relationship to it has changed since the last acceptance).
• Non-material changes (e.g. clarifications, typo fixes, or changes that do not affect your rights or obligations) take effect upon posting and do not require re-acceptance.

This process mirrors, and is enforced by, the consent-status mechanism described in House Privacy Policy §9 and implemented by the Service's material flag on each registered document version: a material revision is published as a new version with material = true, which causes every previously-accepting user to be flagged as owing re-acceptance until they affirmatively accept the new version, exactly as described above — the legal commitment in this section and the system's actual behavior are the same thing, not two separate promises.

We do not reserve, and do not exercise, an unrestricted unilateral right to change these Terms with your mere continued use as the acceptance mechanism. A material change requires you to be asked, and to say yes.

21. No Retroactive Changes

A revision to these Terms applies prospectively only, from the effective date shown on the version you accept. It does not retroactively apply to your conduct, User Content, or any dispute that arose before that effective date, and does not retroactively change the terms that governed a transaction, acceptance, or dispute that occurred while a prior version was in effect.

22. Miscellaneous

• Entire agreement / integration. These Terms — meaning these House Terms, the House Privacy Policy, and the applicable app's Addendum — are the entire agreement between you and us regarding the Service, and supersede any prior or contemporaneous agreements or understandings on that subject. The Privacy Policy and Addendum are incorporated by reference and are part of these Terms; this integration clause does not exclude them.
• Severability. If any provision of these Terms (other than as specifically addressed by the §18.8 arbitration-severability rule, which controls for that section) is held unenforceable, that provision is limited or severed to the minimum extent necessary and the remaining provisions remain in full force.
• No waiver. Our failure to enforce a provision is not a waiver of it.
• Assignment. You may not assign or transfer these Terms without our prior written consent; we may assign these Terms to an affiliate or in connection with a merger, acquisition, reorganization, or sale of assets. Any assignment in violation of this section is void.
• Force majeure. We are not liable for any delay or failure to perform caused by events beyond our reasonable control (e.g. acts of God, natural disaster, war, terrorism, civil unrest, labor conditions, governmental action, internet/utility/hosting-provider failures, or third-party platform outages).
• Notices. We may give you notice through the Service, or by email or other contact information associated with your account; a notice we send is effective when sent. You give us notice at the contact address in §23 (and, for disputes, as §18 requires); a notice you send is effective when we receive it. Where applicable law requires a particular notice method, that method controls.
• No third-party beneficiaries. These Terms do not create any third-party- beneficiary rights, except that where an app is operated by an entity distinct from the identity-provider entity (§3, §6), each such entity is an intended beneficiary of the House Terms it relies on and may enforce them directly.
• Headings / interpretation. Section headings are for convenience only. "Including" means "including without limitation."
• Language. These Terms are made in English. If we provide a translation, it is for convenience only and the English version controls in the event of any conflict, except where applicable law requires otherwise.
