Terms of Service

Effective date: 2026-08-09 — permanent copy of this version. The current Terms of Service is always at kiribook.app/terms/.

These Terms of Service ("Terms") are a legal agreement between you and KiriBook, LLC, a South Dakota limited liability company ("KiriBook," "we," "us," or "our"), governing your use of the KiriBook household address book application at kiribook.app and related websites and services (the "Service").

Please read Section 15 (Governing Law, Arbitration, and Disputes) and Sections 11 and 12 (Disclaimers and Limitation of Liability) carefully. They affect your legal rights. Section 15 requires most disputes to be resolved by individual binding arbitration, waives your right to a jury trial and to participate in a class action, and gives you 30 days to opt out of arbitration.

By creating an account or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

1. Eligibility and age

You must be at least 18 years old to open an account, agree to these Terms, or purchase a subscription. By creating an account or using the Service, you represent and warrant that you are 18 years of age or older and have the legal capacity to enter into a binding contract. At signup you are asked to affirmatively confirm this by agreeing to a statement that you are 18 or older and agree to these Terms; you may not open an account if that representation is untrue.

The Service is intended for adults. We do not knowingly allow anyone under 18 to open an account in their own name or to be charged for a subscription, and if we learn a minor has done so we may suspend or terminate the account. This does not prevent an adult account holder from allowing members of their household, including their own minor children, to view or help maintain information within the account holder's own account. In that case the adult account holder remains the responsible party, is bound by these Terms, and is responsible for all activity in the account; the minor is not treated as an independent user and owes no subscription.

If you use the Service on behalf of an organization, you represent that you are authorized to bind that organization to these Terms, and "you" refers to that organization.

2. Accounts

You are responsible for the information you provide when registering and for keeping it accurate. You are responsible for safeguarding your password and for all activity under your account. Enable two-factor authentication for stronger protection. Notify us promptly at support@kiribook.app if you suspect unauthorized use of your account. You may not share your account or let others use it except through features we provide for that purpose or as permitted in Section 1 (household members, including your minor children, acting within your account under your supervision and responsibility).

3. The Service

KiriBook is a tool for keeping a household address book: tracking households and people, mailing addresses and address history, phone numbers, emails, relationships, important dates, tags and mailing lists, events and guest lists, and for importing, validating, exporting, and syncing that information. Features vary by plan and may change over time. We may add, modify, or discontinue features at our discretion.

4. Subscriptions, billing, cancellation, and renewals

Free and paid plans. KiriBook offers a free tier and a paid "Full Access" subscription. Current pricing is presented in the Service. As of the effective date, Full Access is $59 per year.

Payment. Paid subscriptions are billed through our payment processor, Stripe. By subscribing, you authorize us and Stripe to charge your payment method for the applicable fees, including taxes.

Automatic renewal and your consent. When you subscribe, you expressly authorize KiriBook and Stripe to automatically renew your subscription at the end of each term and to charge your payment method the then-current fee (plus applicable taxes) unless you cancel first. At least 15 days before each renewal, we will send you a reminder that includes the renewal date, the amount, and a link to cancel.

Cancellation. You can cancel at any time from your account's billing settings; no phone call or email is required. Cancellation stops future renewals and takes effect at the end of your current paid term. You keep access to paid features through the end of the term you have already paid for.

No proration. Fees are charged for the full term. We do not provide partial or prorated refunds for unused time if you cancel, downgrade, or delete your account during a term.

Renewal refund window. If you are charged for an automatic renewal, you may request a full refund of that renewal charge within 14 days after the renewal date by contacting support@kiribook.app, provided it is your first refund request for that renewal. After that window, renewal fees are non-refundable except where required by law.

Other refunds. Except for the renewal refund window above and where required by law, fees are non-refundable.

Price changes. We may change prices. We will give you notice before a price change affects you, and the new price applies at your next renewal.

Non-payment. If a payment fails, we may suspend or downgrade your access to paid features until payment is resolved.

5. Your content

You own your content. As between you and KiriBook, you retain all rights to the information, images, and other content you add to the Service ("Your Content").

License to operate the Service. You grant KiriBook a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, display, and back up Your Content solely to operate, provide, secure, and improve the Service and to perform the functions you request (such as validating addresses, syncing contacts, reading uploaded images, generating exports and labels, and sending invitations). This license ends when you delete Your Content or your account, except for residual copies retained in backups for a limited time and information we must keep by law.

Your responsibility for information about others. Most content in KiriBook is information about other people. You represent and warrant that you have the right to collect, store, and use that information in KiriBook, and that your use complies with applicable law and does not violate the privacy or other rights of those people. You are solely responsible for how you use contact information, including any communications, mailings, invitations, or updates you send or trigger through the Service.

Our role and commitments for contact data. You decide what contact information goes into your account and how it is used; KiriBook processes it on your behalf. Where United States state privacy laws apply to your use of the Service, KiriBook acts as a "service provider," "contractor," or "processor" (as those terms are defined in the California Consumer Privacy Act and comparable state laws) for that contact information, and this subsection forms the contract terms those laws require between us. KiriBook:

  1. Processes contact data only to provide the Service to you, on your instructions (your configuration and use of the Service's features are those instructions), and for the limited business purposes of operating, securing, troubleshooting, and supporting the Service.
  2. Does not sell contact data and does not share it for cross-context behavioral advertising, as "sell" and "share" are defined under applicable law.
  3. Does not retain, use, or disclose contact data for any purpose other than those stated above, including any commercial purpose outside our direct business relationship with you, and does not combine it with personal information received from other sources except as applicable law permits.
  4. Does not use contact data to train generally available artificial intelligence models, and sends images processed by our AI-assisted import to our AI provider under terms that prohibit training on that content, as described in the Privacy Policy.
  5. Requires everyone with access to contact data to be bound by a duty of confidentiality.
  6. Engages subprocessors only under a written contract imposing these same obligations, and identifies our current subprocessors in the Privacy Policy.
  7. Maintains reasonable security measures appropriate to the data, as described in the Privacy Policy.
  8. Assists you, taking into account the nature of the processing, in responding to requests from your contacts to access, correct, delete, or limit the use of their information, and in meeting your own security, breach-notification, and assessment obligations.
  9. Makes available to you the information reasonably necessary to demonstrate our compliance with this subsection, and cooperates with reasonable assessments of our processing, which we may satisfy by providing documentation or a report.
  10. Will notify you if we determine that we can no longer meet our obligations under applicable state privacy law, and you may take reasonable and appropriate steps to stop and remediate any unauthorized use of contact data.
  11. Deletes or returns contact data when we stop providing the Service to you, subject to the retention periods, backup practices, and legal retention requirements described in the Privacy Policy.

KiriBook understands these restrictions and will comply with them. This subsection does not apply to information about you as an account holder (such as your name, login credentials, and billing information), which KiriBook processes as a business or controller in its own right, as described in the Privacy Policy.

6. Acceptable use

You agree not to:

  1. Use the Service for any unlawful purpose or in violation of any applicable law or regulation, including data-protection and anti-spam laws (such as CAN-SPAM and the TCPA) when using contact data or sending communications through or based on the Service.
  2. Store or transmit information you do not have the right to store or transmit, or use the Service to harass, stalk, harm, or infringe the rights of others.
  3. Upload malicious code, attempt to gain unauthorized access to the Service or other accounts, probe or circumvent security or account-isolation controls, or disrupt the Service.
  4. Scrape, reverse engineer, resell, or build a competing product from the Service, except to the extent this restriction is prohibited by law.
  5. Use automated means to access the Service in a way that exceeds reasonable use or burdens our infrastructure, or exceed rate limits or usage limits.
  6. Misrepresent your identity or affiliation, or use the Service to send unsolicited bulk communications.

We may investigate and take action, including suspending or terminating accounts, for violations.

7. Third-party services and integrations

The Service integrates with third-party services (for example, Stripe for payments, Resend for email, Anthropic for image reading, Smarty and OpenStreetMap for addresses, and Google or Microsoft for contact sync). Your use of those integrations may be subject to the third party's own terms, and we are not responsible for third-party services. If you connect an integration, you authorize us to access and exchange data with it as needed to provide the feature, and you are responsible for your use of that integration.

8. AI, address validation, and accuracy

AI-assisted import. Features that read text from uploaded images use automated AI processing and may produce errors. You are responsible for reviewing and confirming the accuracy of any information imported this way before relying on it.

Address validation. Address standardization and geocoding rely on third-party data and may be incomplete or inaccurate. Verify addresses before using them for mailings or other important purposes.

The Service does not guarantee successful delivery of any physical mail or electronic communication.

9. Intellectual property

The Service, including its software, design, "KiriBook" name and branding, and all related intellectual property, is owned by KiriBook, LLC and its licensors and is protected by law. We grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for its intended purpose while these Terms are in effect. You may not use our name or branding without our permission.

10. Feedback

If you submit feedback, ideas, or suggestions, you grant us a perpetual, irrevocable, royalty-free license to use them without restriction or obligation to you. Note that feedback you submit through in-product feedback features may be visible to us and used to improve the product across all accounts.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR THAT DATA WILL ALWAYS BE ACCURATE OR PRESERVED. YOU ARE RESPONSIBLE FOR MAINTAINING YOUR OWN BACKUPS OF IMPORTANT DATA, WHICH THE EXPORT FEATURES SUPPORT.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KIRIBOOK AND ITS OWNERS, EMPLOYEES, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATED TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) FIFTY U.S. DOLLARS ($50). SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THESE MAY NOT APPLY TO YOU.

13. Indemnification

You agree to indemnify and hold harmless KiriBook, LLC and its owners, employees, and service providers from any claims, damages, losses, and expenses (including reasonable legal fees) arising from your Content, your use of the Service, your violation of these Terms, or your violation of any law or the rights of any third party, including the privacy rights of people whose information you store.

14. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you violate these Terms, if required by law, or if we discontinue the Service. Upon termination, your right to use the Service ends. Sections that by their nature should survive termination (including ownership, feedback, disclaimers, limitation of liability, indemnification, and Section 15) will survive. You can export Your Content before terminating; after account deletion, we handle remaining data as described in the Privacy Policy.

15. Governing law, arbitration, and disputes

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES MOST DISPUTES BETWEEN YOU AND KIRIBOOK TO BE RESOLVED BY INDIVIDUAL BINDING ARBITRATION INSTEAD OF IN COURT. IT WAIVES YOUR RIGHT TO A JURY TRIAL AND YOUR RIGHT TO PARTICIPATE IN A CLASS ACTION. YOU MAY OPT OUT OF ARBITRATION WITHIN 30 DAYS, AS DESCRIBED BELOW, AND OPTING OUT WILL NOT AFFECT YOUR ACCOUNT.

Governing law. These Terms and any dispute between you and KiriBook are governed by the laws of the State of South Dakota, without regard to its conflict-of-laws rules. The Federal Arbitration Act governs the interpretation and enforcement of this Section.

Informal resolution first. Before starting an arbitration or a court case, you and KiriBook agree to try to resolve the dispute informally. Send a written notice of dispute to support@kiribook.app, or to the mailing address in Section 18, that includes your name, the email address on your account, a description of the dispute, and the relief you are seeking; we will send our notice to the email address on your account. Both of us agree to work in good faith to resolve the dispute for 60 days after the notice is received. Completing this step is a condition of starting arbitration, and any applicable limitations period is paused while it runs. Either of us may still file in small-claims court during this period.

Agreement to arbitrate. Except for the claims described under "Exceptions" below, you and KiriBook agree that any dispute, claim, or controversy arising out of or relating to these Terms, the Service, or our relationship will be resolved by binding arbitration on an individual basis, and not in court. This includes claims that arose before you accepted these Terms and claims that arise after your account ends. The arbitrator decides all issues, including the scope, interpretation, and enforceability of this arbitration agreement, except that a court, not an arbitrator, decides whether the individual-basis requirement below is enforceable.

Exceptions. Either of us may (a) bring an individual claim in small-claims court, so long as it remains in that court and proceeds on an individual basis, and (b) seek injunctive or other equitable relief in court to address unauthorized access to or abuse of the Service or infringement or misuse of intellectual property. Nothing in this Section prevents you from reporting a concern to a government agency or participating in a proceeding brought by one.

How arbitration works. The arbitration will be administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, as modified by these Terms. If the AAA is unavailable or declines to administer the arbitration, you and KiriBook will agree on another established administrator, or a court may appoint one. A single arbitrator will decide the dispute. Unless we agree otherwise, the arbitration will be conducted by videoconference or telephone, or on the written submissions alone; if an in-person hearing is required, it will be held in the county where you live or another location we both agree to. The arbitrator may award any relief that a court could award to you individually, including statutory attorney fees where a statute provides for them, and may not award relief on behalf of anyone else. The arbitrator's award is final and binding, and judgment on it may be entered in any court with jurisdiction.

Arbitration costs. Filing, administrative, and arbitrator fees are allocated under the AAA Consumer Arbitration Rules, which limit the amount a consumer pays and assign the remainder to KiriBook. Each of us is otherwise responsible for our own attorney fees, except where a statute or the arbitrator's award provides otherwise.

Settlement offers. If KiriBook makes a written offer to settle a dispute and the arbitrator awards you no more than that offer, KiriBook is not responsible for your attorney fees or costs incurred after the offer was made, to the extent the applicable rules or law allow that limitation.

Individual basis only; class-action waiver. You and KiriBook agree to bring claims against each other only in an individual capacity, and not as a plaintiff or class member in any class, collective, consolidated, coordinated, or representative proceeding. The arbitrator may not consolidate the claims of more than one person and may not preside over any class or representative proceeding. If a court decides that this individual-basis requirement is unenforceable as to a particular claim or request for relief, then that claim or request for relief, and only that one, will be severed from the arbitration and brought in the state or federal courts located in South Dakota, and the rest of this Section will continue to apply to every other claim. A claim severed this way will be stayed until the arbitration of the remaining claims is complete.

Coordinated filings. If 25 or more demands for arbitration raising substantially similar claims are filed against KiriBook by or with the assistance of the same law firm or coordinated counsel, the demands will be resolved in staged batches of no more than 25 at a time. Each batch will be assigned to a single arbitrator, and no fees are owed for a demand until its batch begins. You and KiriBook agree to work in good faith with the AAA to apply this process, to use the results of the first batch to try to resolve the remaining demands, and that any applicable limitations period is paused for demands awaiting a batch. This paragraph does not restrict any individual claimant's right to have their own claim decided.

Your right to opt out of arbitration. You may opt out of this arbitration agreement within 30 days after you first accept these Terms. To opt out, email support@kiribook.app with the subject line "Arbitration Opt-Out," including your name, the email address on your account, and a statement that you are opting out of arbitration. Opting out is free, does not affect your account or any other part of these Terms, and is the only way to opt out. If you opt out, disputes between you and KiriBook will be resolved in the courts described below.

Court proceedings. For any dispute that is not subject to arbitration (including if you opt out, if a claim is severed under this Section, or for equitable relief under the exceptions above), you and KiriBook agree that the dispute will be brought exclusively in the state or federal courts located in South Dakota. Both of us consent to the personal jurisdiction and venue of those courts and waive any right to a jury trial.

Changes to this Section. If we change this Section after you accept these Terms, you may reject the change by emailing support@kiribook.app within 30 days after the change takes effect, in which case the most recent version you accepted will govern disputes between us.

Survival. This Section survives the termination of these Terms and the closure of your account.

16. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or through the Service and update the "Last updated" date above. Changes take effect when posted (or on a later stated date). Your continued use of the Service after changes take effect means you accept the revised Terms.

Changes to subscription pricing or renewal terms (such as price, term length, or the renewal refund window) will not apply to you until your next renewal, and we will give you advance notice as described in Section 4.

17. General

Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and KiriBook regarding the Service and supersede any prior agreements.

Severability. If any provision is found unenforceable, the rest remains in effect.

No waiver. Our failure to enforce any provision is not a waiver of it.

Assignment. You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, or sale of assets.

Force majeure. We are not liable for delays or failures caused by events beyond our reasonable control.

Notices. We may provide notices to you by email or through the Service. You may send legal notices to the address below.
