These Terms of Service (“Terms”) govern your use of the tatastu.dev website (the “Website”), the Tatastu service provided by Qadri LLC, a Wyoming limited liability company (“Qadri LLC”, “we”, “us”), and any separate purchases offered through the Website. Your use of the Tatastu desktop application is additionally governed by the End-User License Agreement (EULA), and our handling of data is described in our Privacy Policy. If the EULA and these Terms conflict regarding the Software, the EULA controls for the Software; in all other respects (including the Website and the purchase relationship) these Terms control.

Acceptance

By clicking “I agree” (or a similar affirmative control) when prompted, creating an account, using the Service, or making a purchase, you acknowledge that you have read and agree to be bound by these Terms and by the EULA, which is incorporated by reference, and you acknowledge the Privacy Policy. If you do not agree, do not use the Service or make a purchase. Your continued use of the Website is also subject to these Terms.

0. Definitions

“Software”: the Tatastu desktop application and related software, documentation, and updates.
“Website”: the website at tatastu.dev and its subdomains.
“Service”: collectively the Software, the Website, and optional Tatastu-operated hosted services.
“Historical Subscription”: a Tatastu Premium subscription purchased before Tatastu stopped offering new Premium subscriptions.
“You”: the person who uses the Service or makes a purchase, or an entity acting through that person where this Agreement permits entity use.

1. The service

Tatastu is a local-first desktop application for AI-assisted software development. Software features are not restricted behind a Tatastu purchase. Access to optional hosted services may require a Tatastu account, an authorized device, and available service capacity. Access to a feature or hosted capacity does not itself grant a commercial-use license. AI model usage is not included; you bring your own AI provider account (see the EULA).

2. Eligibility & accounts

You must be able to form a binding contract. You are responsible for keeping your account and device credentials confidential and for activity under them. You must use your own account and authorized devices for optional hosted services.

3. Purchases, Historical Subscriptions, and merchant of record

3.1 No Software purchase. Tatastu does not sell access to the Software or its features. Free access to Software features does not change the personal and noncommercial license in the EULA or erase rights and obligations that arose under a Historical Subscription.

3.2 Historical Subscriptions. No Historical Subscription remains active. For questions about a past purchase, contact support. Refunds, legally required notices, and other rights that arose under a Historical Subscription are handled under the terms that applied to that purchase and applicable law; these Terms do not waive a refund or other accrued right.

3.3 Refunds and statutory rights. Refunds for Historical Subscriptions are handled by the merchant of record under the applicable checkout terms and law. Nothing in these Terms limits any non-waivable refund, withdrawal, or consumer right.

4. Acceptable use

You agree not to misuse the Website or Service, including by attempting to circumvent account, device, security, or service-capacity controls, scraping, interfering with the Service, or using it unlawfully. Software-specific restrictions are in the EULA. You represent that you are not located in, and will not use the Service in, any country subject to comprehensive U.S. sanctions, and that you are not on any U.S. government denied-party or restricted-party list. You will comply with all applicable export-control and sanctions laws.

5. Intellectual property and open-source components

The Tatastu name, Website, and Software are owned by Qadri LLC and its licensors, except for components licensed under open-source licenses. These Terms grant no rights except as expressly stated.

Portions of the Software are derived from the open-source 1Code project and are licensed under the Apache License, Version 2.0 (the “Apache Components”); a copy of the Apache License 2.0 and the required NOTICE file are distributed with the Software. Nothing in these Terms limits, restricts, or adds conditions to the rights granted to you under the Apache License 2.0 with respect to the Apache Components; to the extent of any conflict, the Apache License 2.0 controls for those components.

6. Third-party services

The Service interoperates with third-party services you choose to connect (AI providers, developer tools). We are not responsible for those services.

7. Disclaimers & limitation of liability

The Website and Service are provided “AS IS” and “AS AVAILABLE” without warranties of any kind. To the maximum extent permitted by law, Qadri LLC disclaims all implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. AI-assisted output may be inaccurate or unsuitable; you are responsible for reviewing it before relying on it.

To the maximum extent permitted by law, Qadri LLC’s 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 to us (or to our merchant of record on our behalf) for the Service in the twelve (12) months before the event giving rise to the claim, or (b) USD $100. Qadri LLC will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, data, or goodwill.

Nothing in these Terms limits liability that cannot be limited under applicable law (including certain consumer rights and liability for fraud, gross negligence, willful misconduct, or death or personal injury caused by negligence). Where the EULA applies to the Software and conflicts with this Section, the EULA controls for the Software only.

8. Indemnification

You will defend, indemnify, and hold harmless Qadri LLC and its officers, members, and agents from any claims, damages, liabilities, and expenses (including reasonable attorneys’ fees) arising out of (a) your use of the Service, (b) your violation of these Terms, the EULA, or applicable law, (c) your violation of any third-party rights or any third-party service’s terms (including your AI provider account), or (d) content or code you submit, generate, or process using the Service. This Section does not apply to the extent a claim arises from Qadri LLC’s own gross negligence or willful misconduct.

9. Termination

We may suspend or terminate access for breach of these Terms or the EULA, or as required by law. You may stop using the Service at any time.

10. Governing law & disputes

These Terms are governed by the laws of the State of Wyoming, USA, with venue in the state and federal courts located in Wyoming, except where applicable consumer-protection law gives you the right to bring proceedings in your place of residence. This provision is consistent with the corresponding clause in the EULA. Nothing in these Terms excludes or limits any rights you have as a consumer under the mandatory laws of your country or state of residence that cannot lawfully be excluded.

11. General

(a) Entire agreement. These Terms, together with the EULA, the Privacy Policy, and any terms applicable to a separate purchase presented at checkout, are the entire agreement between you and Qadri LLC regarding the Service and supersede all prior agreements.

(b) Severability. If any provision is held unenforceable, it will be modified to the minimum extent necessary or severed, and the remaining provisions remain in full force.

(d) Assignment. You may not assign these Terms without our written consent. We may assign these Terms, including in connection with a merger, acquisition, or sale of assets.

(e) Force majeure. Neither party is liable for delays or failures caused by events beyond its reasonable control.

(f) Notices. We may provide notices via the Website, in the App, the email associated with your account or purchase, and, for a Historical Subscription, the applicable customer portal. Legal notices to us must be sent to support@tatastu.dev and to the mailing address in Section 13.

(g) Survival. The sections on intellectual property, disclaimers and limitation of liability, indemnification, governing law and disputes, and these general provisions survive termination.

12. Changes

We may update these Terms; material changes will be communicated in-app, by email, and/or posted on tatastu.dev with an updated effective date, and continued use after the effective date constitutes acceptance.
