# Terms of Service **Last updated:** April 24, 2026 ## 1. Acceptance By installing the CourierAI browser extension, visiting the CourierAI website, or otherwise using the software and service (together, the "Service"), you agree to these Terms of Service. If you do not agree, do not use the Service. You must be at least 13 years old, or the minimum age of digital consent in your jurisdiction (whichever is higher), to use the Service. **These Terms contain a binding arbitration agreement and a class action waiver (Section 13). They affect your legal rights. Please read them carefully.** ## 2. What CourierAI is CourierAI is a browser-based client that lets you send requests to third-party Large Language Model ("LLM") APIs using your own API keys. The Service does not operate its own LLM backend and does not run any server that processes your messages. When you send a message, it is sent from your browser - by way of the CourierAI extension, which handles the HTTPS request on the browser's behalf - directly to the LLM provider you selected, using credentials you supplied. No intermediate server operated by CourierAI is involved. CourierAI is currently an unincorporated project maintained by its contributors. If operations are transferred to a legal entity in the future, these Terms will be updated and that entity will assume the rights and obligations set out here. ## 3. Your API keys and your costs You are solely responsible for: - Obtaining API keys from the LLM providers you wish to use. - Complying with each provider's own terms of service, acceptable use policy, and rate limits. - All charges incurred on your API keys as a result of requests made through CourierAI, including requests you did not personally review. - Keeping your API keys secure and revoking them if compromised. CourierAI does not set, predict, control, or reimburse the prices charged by LLM providers. ## 4. Third-party services The Service connects to LLM providers that are independent of CourierAI. We do not control their availability, pricing, model behavior, training data, retention practices, or output. Your use of each provider is governed by that provider's own terms: - Anthropic - - OpenAI - - Google - Other providers may be added over time. You are responsible for reviewing and accepting the terms of each provider you use. **Provider enforcement actions.** Each LLM provider independently sets and enforces its own policies. If a provider warns you, restricts your access, suspends your account, bans you, revokes your API key, charges you, or takes any other action against you in connection with your use of their API - whether or not that use was through CourierAI - CourierAI is not responsible and you will have no claim against CourierAI arising from that action. Disputes about provider enforcement are strictly between you and the provider. ## 5. LLM outputs LLM outputs are generated by third-party models. They may be inaccurate, offensive, biased, outdated, unsafe, or otherwise unsuitable for a given purpose. Do not rely on LLM outputs for medical, legal, financial, safety-critical, or other consequential decisions. CourierAI is a conduit to these models and makes no representation about the quality, accuracy, or suitability of their outputs. ## 6. Acceptable use You agree not to use the Service to: - Violate any law or any third party's rights. - Violate any LLM provider's acceptable use policy. - Generate content that sexually exploits minors, incites violence, facilitates real-world harm, or enables targeted harassment. - Interfere with, disrupt, or attempt to compromise the Service, other users, or any LLM provider's infrastructure. - Resell the Service as a hosted product or misrepresent it as your own, or otherwise use the Service in ways not permitted by the PolyForm Small Business License (see Section 7). **Cooperation with legal process and providers.** We reserve the right to investigate suspected violations of these Terms and to cooperate with LLM providers, law enforcement, and other authorities where legally required or where we believe in good faith that cooperation is appropriate to protect the Service, its users, or third parties. ## 7. License and source availability The source code for CourierAI is made publicly available under the PolyForm Small Business License 1.0.0 (see the `LICENSE` file in the repository). The Service itself - the software, the website, the trademarks "CourierAI" and any associated marks, and the overall product - is proprietary to CourierAI and its maintainers. The PolyForm Small Business License is a **source-available** license, not an OSI-approved open source license. It allows personal use and use within small businesses (as defined in the license), but not distribution or use by larger organizations without separate permission. For commercial license inquiries, contact blake@courierai.net. ## 8. Intellectual property and no backend commitment You retain all rights to the content you create using the Service (subject to the provider terms you accepted). CourierAI claims no ownership of your prompts, messages, or LLM outputs. CourierAI is designed such that your prompts, messages, API keys, and LLM outputs never pass through any server operated by CourierAI. It is our intention to preserve this architecture indefinitely. If this ever changes in a future version of the Service, these Terms and the Privacy Policy will be updated before the change takes effect, and you will be notified. ## 9. No warranty **THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, ACCURACY, OR UNINTERRUPTED AVAILABILITY.** The Service may be discontinued, changed, or made unavailable at any time without notice. ## 10. Limitation of liability **TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL THE MAINTAINERS OR CONTRIBUTORS OF COURIERAI BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, LOST DATA, LOST API CREDITS, OR THE COST OF SUBSTITUTE SERVICES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE, WHETHER IN CONTRACT, TORT, OR OTHERWISE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.** **TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE TOTAL AGGREGATE LIABILITY OF COURIERAI AND ITS MAINTAINERS FOR ANY AND ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) THE AMOUNT YOU PAID TO COURIERAI IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) TEN U.S. DOLLARS (USD 10). BECAUSE COURIERAI DOES NOT CHARGE USERS FOR THE SERVICE, (A) WILL TYPICALLY BE ZERO.** **Nothing in these Terms limits or excludes liability for gross negligence, willful misconduct, fraud, or any other liability that cannot be limited or excluded under applicable law.** ## 11. Indemnification You agree to defend, indemnify, and hold harmless CourierAI and its maintainers from any claim, demand, loss, or damage (including reasonable legal fees) arising out of or related to: your use of the Service; your violation of these Terms; your violation of any LLM provider's terms or acceptable use policy, including any claim by a provider arising from your use of their API through the Service; or your violation of any law or third-party right. ## 12. Termination You may stop using the Service at any time by uninstalling the extension and no longer visiting the website. We may discontinue the Service, remove it from distribution channels (for example, the Chrome Web Store), or withdraw support at any time, with or without notice. Because the Service runs entirely in your browser, we have no ability to terminate an individual user's installed copy. Sections 3, 4, 5, 8, 9, 10, 11, 13, and 14 survive termination. ## 13. Arbitration and class action waiver **PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.** You and CourierAI agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service (a "Dispute") will be resolved by binding individual arbitration rather than in court, except as set out below. **Arbitration rules.** The arbitration will be administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules, as modified by these Terms. The AAA's rules are available at . The arbitration may be conducted by telephone, online, or by written submissions; in-person hearings will occur only if you request one and the arbitrator agrees, and will take place in a location reasonably convenient to you. **Class action waiver.** You and CourierAI agree that each may bring claims against the other only in your or its individual capacity, and not as a plaintiff or class member in any class, collective, or representative proceeding. The arbitrator may not consolidate more than one person's claims or preside over any form of representative or class proceeding. **Exceptions.** This Section 13 does not apply to: (a) claims that qualify for small claims court in the claimant's county of residence, so long as the claim remains individual and stays in that court; (b) claims for injunctive or other equitable relief to protect intellectual property rights; or (c) any Dispute that cannot be required to be arbitrated under applicable law. **Opt-out.** You may opt out of this arbitration agreement by emailing blake@courierai.net with the subject line "Arbitration Opt-Out" within 30 days of first accepting these Terms. Your email must include your name and a statement that you decline to be bound by this arbitration agreement. If you opt out, no other part of these Terms is affected. **Severability within this section.** If the class action waiver above is found unenforceable as to a particular claim, that claim will be severed from this arbitration agreement and heard in the courts identified in Section 14, while all other claims remain in arbitration. ## 14. Governing law and venue These Terms are governed by the laws of the State of New Mexico, without regard to its conflict-of-law principles. Subject to Section 13 (Arbitration), any dispute that is not subject to arbitration - or that a court of competent jurisdiction determines cannot be arbitrated - will be brought exclusively in the state or federal courts located in Bernalillo County, New Mexico, and you consent to personal jurisdiction there. ## 15. Changes to these Terms We may update these Terms from time to time. The updated version will be published at the same URL with a new "Last updated" date. Material changes will also be surfaced in the website itself the next time you open it, so you don't have to check this page to find out. Your continued use of the Service after changes take effect constitutes acceptance of the updated Terms. ## 16. Contact Questions about these Terms: blake@courierai.net
