January API Developer Terms

Version 1.0

Effective date: August 26, 2026


These Developer Terms (the "Terms") are a binding agreement between you ("you" or "Customer") and January, Inc. ("January," "we," "us") covering your access to and use of the January API, SDKs, and developer dashboard (together, the "Service").

By checking the box at signup, creating an account, or calling the API, you agree to these Terms. If you are accepting on behalf of a company or other organization, you represent that you have authority to bind that organization, and "you" means that organization.

Please read Sections 2, 8, and 9 carefully. They prohibit use with protected health information, disclaim warranties, and limit our liability.

1. Plans, API Calls, and Fees

1.1 Plans. The Service is offered on the plans published at https://january.ai/pricing. Free and Pro plans are governed by these Terms. Enterprise plans are not — see Section 11.

1.2 Usage limits. Your plan's monthly API call allowance and API key limit are enforced limits, not targets. We may throttle, queue, or reject requests once you reach your allowance, and may apply per-endpoint rate limits described in the Documentation. Allowances reset at the start of each billing period and do not carry over.

1.3 Fees and billing. Paid plans are billed monthly in advance through our payment processor. You authorize us to charge your payment method on each renewal date until you cancel. Fees are non-refundable except where required by law, including for partial months. You are responsible for applicable taxes other than taxes on our income.

1.4 Price changes. We may change pricing or plan allowances with up to 30 days' notice by email. Changes take effect at your next billing period. If you do not agree, you may cancel before that date under Section 10.

2. No Protected Health Information

2.1 The Service under these Terms is not HIPAA-compliant and is not covered by a Business Associate Agreement. We will not enter into a Business Associate Agreement in connection with a Free or Pro plan.

2.2 You will not submit to the Service any protected health information as defined under HIPAA, or any information from or on behalf of a covered entity or business associate that would make January a business associate.

2.3 If your use involves protected health information, you must move to an Enterprise plan (Section 11) before submitting any such data.

2.4 The Service is not a medical device and does not provide medical advice, diagnosis, or treatment. You will not use or present the Service, or any Output, for clinical decision-making, diagnosis, treatment, or emergency use, and you will not state or imply that it is suitable for those purposes.

3. Your License

3.1 Grant. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license during the term to:

(a) call the API in accordance with the Documentation;

(b) display Output to your end users within your application;

(c) store and use Output during the term for the purposes permitted by these Terms; and

(d) embed our SDKs and client libraries in your application in object code form and distribute them as incorporated in that application.

"Output" means the data and results returned by the Service. Where we make any SDK or component available under a separate license, including an open-source license, that license governs your use of that component.

3.2 Territory. The license in Section 3.1 is limited to use in the United States. You represent that you are established in the United States and that you will make the Service available only to end users located in the United States. We may geo-restrict access and may suspend or terminate accounts we reasonably believe are being used outside the United States.

3.3 Eligibility. You must be at least 18 years old and not barred from receiving the Service under applicable export control or sanctions laws.

4. Restrictions

You will not, and will not permit anyone else to:

(a) reverse engineer, decompile, or attempt to derive the source code, model weights, parameters, or underlying logic of the Service or of our machine learning models, including through model extraction or distillation techniques. Subject to this restriction, you may use Output with your own or third-party AI systems, including to train or fine-tune models, in connection with your permitted use;

(b) store or use Output in a manner that replicates or reconstructs our underlying data store or databases. For clarity, you may store and use Output on a per-user basis, or aggregated and anonymized across your end users;

(c) resell, sublicense, or redistribute the Service or Output as a standalone data feed, database, or API, or otherwise make the Service available to third parties other than as a feature of your own application;

(d) access the Service other than through the API, or circumvent any rate limit, usage allowance, key limit, or security feature;

(e) share, publish, or expose your API keys, or allow the API to be called directly by an untrusted client;

(f) remove or obscure any proprietary notices, or misrepresent the source of the Output;

(g) provide glucose curve predictions to any third-party platform or service. You may write macronutrient and other nutrient data to third-party health data platforms (for example, Apple Health or Google Health Connect) at your end user's direction; or

(h) use the Service in violation of applicable law.

API keys. You are responsible for keeping your API keys secure and for all activity under your account. Notify us promptly at support@january.ai if you believe your keys have been compromised, and we will issue replacements and revoke the old keys.

5. Your End Users

If you make the Service available to end users through your application, your end user terms and privacy policy must:

(a) permit you to transmit end user data to third-party service providers, including January, for processing;

(b) not make any warranty or representation on our behalf; and

(c) not state or imply that the Service provides medical advice, diagnosis, or treatment.

6. Data and Privacy

6.1 As between us, you are the controller (or, under applicable U.S. state privacy laws, the business) with respect to end user data you submit through the Service. We process that data as your service provider and processor, solely to provide and maintain the Service in accordance with these Terms, and to create de-identified or aggregated data that does not identify you or any end user.

6.2 We will not sell or share end user data, or use it for cross-context behavioral advertising.

6.3 Our handling of data is described in our Privacy Policy at https://january.ai/privacy-policy.

6.4 Where an end user separately establishes a direct relationship with January, our Privacy Policy governs that relationship.

6.5 Deletion. Upon termination or expiration of your account, you will delete all stored Output within thirty (30) days, except to the extent retention is required by applicable law. We have no obligation to preserve or return any Output.

7. Service Levels, Support, and Changes

7.1 No service level commitment. Free and Pro plans carry no uptime, availability, latency, or support response commitment. Any figures published in our documentation or service description are targets for planning purposes only and are not binding. Service level commitments and service credits are available only on Enterprise plans.

7.2 Support. Support is provided through the channels listed for your plan. We provide support to you, not to your end users.

7.3 Changes to the Service. We may add, modify, deprecate, or discontinue features, endpoints, or the Service itself. We will use reasonable efforts to give advance notice of breaking changes through the dashboard, the changelog, or email.

7.4 Third-party data. Portions of the Output are derived from data licensed to us by third parties. If our rights to that data change or terminate, we may modify or discontinue the affected portions of the Service and require you to cease use of and delete the affected Output within thirty (30) days. This is not a breach of these Terms. Where we notify you that attribution to a data source is required, you will display the attribution specified in the Documentation on the screens where that data appears.

8. Warranties

THE SERVICE, SDKs, DOCUMENTATION, AND OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND. WE DISCLAIM ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT OUTPUT WILL BE ACCURATE OR COMPLETE. NUTRITION AND GLUCOSE-RELATED OUTPUT IS ESTIMATED AND MAY BE INACCURATE.

9. Liability and Indemnity

9.1 No indemnity from January. We do not indemnify you under these Terms.

9.2 Your indemnity. You will defend, indemnify, and hold harmless January and its officers, directors, employees, and agents from any third-party claim arising from your application, your content, your use of the Service, your breach of these Terms, or any representation you make to an end user about the Service.

9.3 Exclusion of damages. WE WILL NOT BE LIABLE FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, COVER, OR CONSEQUENTIAL DAMAGES, OR FOR LOST PROFITS, REVENUE, OR DATA, ARISING FROM OR RELATED TO THESE TERMS, EVEN IF ADVISED OF THE POSSIBILITY. The exclusions and cap in this Section 9 do not apply to Customer's indemnification obligations under Section 9.2.

9.4 Cap. OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID US IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).

10. Term, Suspension, and Termination

10.1 Term. These Terms apply from your acceptance until your account is terminated.

10.2 Your cancellation. You may cancel at any time in the dashboard. Cancellation takes effect at the end of your current billing period. Fees already paid are not refunded.

10.3 Our termination. We may terminate or suspend your account or any API key: immediately, where we reasonably believe there is a security risk, a threat to the Service, non-payment, or a breach of Section 2 (No Protected Health Information), Section 3.2 (Territory), or Section 4 (Restrictions); and otherwise on 30 days' notice. We may also terminate or suspend your account, any API Key, or the Service, for any reason or no reason, upon 30 days’ notice for paid plans and immediately for free plans.

10.4 Effect. On termination, your license ends, you must stop calling the API, and Section 6.5 (Deletion) applies.

10.5 Survival. Sections 4, 6, 8, 9, 10.4, 10.5, 12, and 13 survive termination.

10.6 No termination liability - We will have no liability to you arising from any suspension or termination under this Section 10.

11. Enterprise

Business Associate Agreements, HIPAA-aligned data practices, SOC 2 reporting, volume pricing, custom call volumes, service level commitments with credits, indemnification, and dedicated support are available only under a separate Enterprise agreement. Contact us at https://january.ai/book-a-demo to move to an Enterprise plan.

12. Changes to These Terms

We may update these Terms. For any material change, we will give up to 30 days' notice by email, and the change takes effect at the start of your next billing period. For accounts without a paid billing period, changes take effect 30 days after notice. For material changes, we may require you to accept the updated Terms before continuing to use the Service. If you do not agree, your remedy is to cancel under Section 10.2 before the effective date. Continued use after the effective date constitutes acceptance. We maintain prior versions at https://january.ai/developer-terms.

13. General

13.1 Feedback. If you send us feedback or suggestions, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use it for any purpose.

13.2 Governing Law. These Terms are governed by the laws of the State of California, without regard to conflict of law rules.

13.3 Dispute Resolution; Arbitration Agreement; Class Action Waiver. PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT.

(a) Agreement to Arbitrate. Except as set out below, you and January 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 arbitration on an individual basis, rather than in court, except that either party may bring an individual action in small claims court.

(b) Procedures. The arbitration will be administered by the American Arbitration Association under its Commercial Arbitration Rules then in effect, before a single arbitrator, seated in San Francisco County, California (or conducted remotely or by written submission at the arbitrator's discretion). Judgment on the award may be entered in any court of competent jurisdiction.

(c) Class Action Waiver. YOU AND JANUARY AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate more than one person's claims and may not otherwise preside over any form of a class or representative proceeding.

(d) Exceptions. Either party may bring an action in court solely for injunctive relief to stop unauthorized use or abuse of the Service, or infringement or misappropriation of intellectual property rights, without first engaging in arbitration.

(e) Severability. If the class action waiver in (c) is found unenforceable as to a particular Dispute, that Dispute (and only that Dispute) will proceed in court rather than arbitration, and the rest of this Section remains in effect.

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

13.5 Entire agreement. These Terms, together with the Documentation and Privacy Policy referenced here, are the entire agreement between us regarding the Service and supersede any prior discussions. If you have signed a separate written agreement with us covering the API, that agreement controls to the extent of any conflict.

13.6 Severability and waiver. If any provision is held unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver of it.

13.7 Force Majeure. Neither party will be liable for any failure or delay in performance under these Terms (other than payment obligations) to the extent caused by circumstances beyond that party's reasonable control, including acts of God, natural disaster, war, terrorism, riot, labor dispute, governmental action, internet or telecommunications failure, denial-of-service or other attack, or failure or unavailability of third-party infrastructure, data sources, or service providers. If such an event prevents a party's performance for more than sixty (60) consecutive days, either party may terminate these Terms on written notice, without liability for that termination.
