End-User License Agreement

Version 1.2·Effective October 2, 2026

This End-User License Agreement (“Agreement”) is a legal agreement between you (“you” or “User”) and Qadri LLC, a Wyoming limited liability company (“Qadri LLC”, “we”, “us”), for the Tatastu desktop application and related software, documentation, and updates (collectively, the “Software”). Your use of the tatastu.dev website and any separate purchase are additionally governed by our Terms of Service, and our handling of data is described in our Privacy Policy. Capitalized terms used but not defined here have the meanings given in the Terms of Service.

By clicking “I agree” (or a similar affirmative control) when prompted, you accept and agree to be bound by this Agreement. If you access or use the Software without clicking “I agree”, your access and use are also subject to this Agreement. If you do not agree, do not install or use the Software.

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; its purchase and servicing terms are described in the Terms of Service.
  • “Apache Components”: the portions of the Software derived from the open-source 1Code project and licensed under the Apache License, Version 2.0.
  • “Your Content”: your code, files, prompts, and other content that you create with or supply to the Software.

1. License grant

Subject to your compliance with this Agreement, Qadri LLC grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Software on devices you own or control for personal and noncommercial use. Software features are available without a purchase, and feature availability does not expand this license to commercial use. A separate written agreement or surviving rights under a Historical Subscription may grant additional use rights according to its terms. This Section does not limit the rights granted by open-source licenses for the Apache Components (Section 7).

2. Software access, account, and authorized devices

2.1 Software access. Software features do not require a purchase. AI model usage remains subject to your own provider account (Section 4). Optional hosted services may be subject to published capacity limits and availability.

2.2 Account and device identity. Optional hosted services may require you to sign in to a Tatastu account and authorize a device. We use account and device credentials to authenticate requests, protect connected resources, associate runs with the correct account, enforce service capacity, and support recovery or revocation. Keep those credentials private and revoke a lost or compromised device through the available recovery process or support.

2.3 Historical Subscriptions. No Historical Subscription remains active. Refunds and any surviving contractual rights under a Historical Subscription are addressed under the terms applicable to that purchase and the Terms of Service. Ending a Historical Subscription does not delete Your Content stored locally.

3. Restrictions

The restrictions in this Section 3 apply only to the proprietary components of the Software and do not apply to any Apache Components or other open-source components, which are governed by their respective licenses (see Section 7). You will not, and will not permit any third party to:

(a) copy, modify, translate, or create derivative works of the proprietary components of the Software except as expressly permitted;

(b) reverse engineer, decompile, or disassemble the proprietary components of the Software, or attempt to derive their source code, except (i) to the extent such activity is permitted by open-source license terms applicable to a given component, or (ii) to the extent these restrictions cannot lawfully be imposed under mandatory applicable law, including the rights to observe, study, and test, and to decompile for interoperability, granted by Articles 5(3) and 6 of Directive 2009/24/EC (and equivalent national laws), and comparable non-excludable rights under the laws of other jurisdictions such as Australia;

(c) rent, lease, lend, sell, sublicense, distribute, or otherwise transfer the proprietary Software or your account or device credentials to any third party;

(d) share, publish, or circumvent account or device credentials, service-capacity controls, or security measures;

(e) remove or alter any proprietary notices;

(f) use Qadri LLC’s confidential information or the non-public design, structure, or organization of the proprietary components of the Software to develop a product that competes with the Software (this does not restrict independently developed software, or any rights you have under the Apache License 2.0 or other applicable open-source licenses); or use the Software for any unlawful purpose.

4. Bring-your-own AI provider

The Software is a client for AI coding assistance. It does not include AI model usage. To use a hosted AI model you must supply, and are solely responsible for, your own credentials and account with a supported AI provider (for example a Claude or ChatGPT plan, or an API key for Anthropic, OpenAI, OpenRouter or OpenCode Go). You may instead run a model locally on your own device. The Software may run your AI provider through an agent harness you select (such as Pi, Claude Code or Codex); you are responsible for using each provider and harness in line with its terms. Your use of any third-party AI provider is governed by that provider’s terms and acceptable-use policies, and you are responsible for all charges and usage incurred under your provider account. Qadri LLC does not resell, meter, or guarantee AI provider availability, output, or pricing.

5. Your content, your credentials, and account data

5.1 Your Content. You retain all rights to Your Content. The Software is local-first: Your Content and your stored credentials remain on your device except where you direct the Software to transmit them (for example, to your AI provider or other services you configure). See the Privacy Policy for details. You are responsible for the security of your device and your credentials. Ending a Historical Subscription, signing out, or losing access to an optional hosted service does not delete Your Content from your device or prevent you from accessing or exporting it locally.

5.2 Account and service data. To provide and secure optional hosted services, Qadri LLC processes the account information used for sign-in, account and authorized-device identifiers and credentials, hosted-run ownership and capacity records, and related security and support data. We may retain historical purchase, license, and device-activation records as needed for Historical Subscription refunds, support, or legal obligations. The Privacy Policy describes these categories, purposes, recipients, and retention.

6. Updates

We may provide updates, which are part of the Software and subject to this Agreement. The Software may check for and download updates automatically. Some updates may be required for the Software’s continued operation or security.

7. Ownership and open-source components

The Software is licensed, not sold. Except for components licensed under open-source licenses, Qadri LLC and its licensors retain all right, title, and interest in and to the Software, including all intellectual property rights.

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. Notwithstanding anything in this Agreement (including Section 3), your rights with respect to the Apache Components are governed solely by the Apache License 2.0, and nothing in this Agreement limits, restricts, or adds conditions to the rights granted to you under that license. To the extent of any conflict between this Agreement and the Apache License 2.0 as applied to the Apache Components, the Apache License 2.0 controls for those components.

8. Third-party services

The Software can connect to third-party services you choose to configure. Those services are governed by their own terms and privacy practices, and Qadri LLC is not responsible for them.

9. Disclaimer of warranties

THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT IT WILL PRODUCE CORRECT OR RELIABLE OUTPUT. AI-ASSISTED OUTPUT MAY BE INACCURATE; YOU ARE RESPONSIBLE FOR REVIEWING AND VERIFYING ALL OUTPUT BEFORE USE.

10. Non-excludable statutory rights

Nothing in this Agreement excludes, restricts, or modifies any guarantee, warranty, right, or remedy that you have under applicable law (including consumer-protection law) that cannot lawfully be excluded, restricted, or modified by agreement, for example, statutory consumer guarantees under the Australian Consumer Law, the UK Consumer Rights Act 2015, and EU Directive 2019/770 on digital content and services. The disclaimers and limitations in Sections 9 and 11 apply only to the extent permitted by such law, and where a right cannot be excluded but liability for its breach may be limited, our liability for that breach is limited to the maximum extent permitted.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL QADRI LLC BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SOFTWARE. QADRI LLC’S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SOFTWARE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO US OR OUR MERCHANT OF RECORD FOR THE SOFTWARE OR SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS (USD 100).

NOTHING IN THIS AGREEMENT LIMITS OR EXCLUDES LIABILITY FOR (A) DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE; (B) FRAUD OR FRAUDULENT MISREPRESENTATION; (C) GROSS NEGLIGENCE OR WILLFUL MISCONDUCT; OR (D) ANY OTHER LIABILITY THAT CANNOT BE LIMITED OR EXCLUDED UNDER APPLICABLE LAW. THE LIMITATIONS IN THIS SECTION 11 DO NOT APPLY TO YOUR INDEMNIFICATION OBLIGATIONS UNDER SECTION 12 OR TO YOUR PAYMENT OBLIGATIONS. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

12. Indemnification

You will defend, indemnify, and hold harmless Qadri LLC and its officers, members, and agents from and against any claims, damages, liabilities, and expenses (including reasonable attorneys’ fees) arising out of or related to (a) Your Content; (b) your use of the Software in violation of this Agreement or applicable law; or (c) your use of any third-party AI provider or other third-party service, including any charges, content, or intellectual-property claims arising from such use. This Section does not apply to the extent a claim arises from Qadri LLC’s own gross negligence or willful misconduct.

13. Purchases, refunds, and merchant of record

Software features do not require a purchase. Polar, acting as merchant of record, handles applicable payment, tax, and refund processing for past purchases under the terms presented at checkout. No Historical Subscription remains active; refund, notice, and other rights that arose under a Historical Subscription remain subject to the terms applicable to that purchase, and support remains available. See the Terms of Service for purchase terms. Nothing in this Section limits non-waivable consumer rights.

14. Termination

This Agreement is effective until terminated. It terminates automatically if you materially breach it or the Terms of Service. A Historical Subscription’s cancellation or expiry does not, by itself, terminate your personal and noncommercial Software license. On termination for breach you must stop using and remove proprietary copies of the Software as required by law; Your Content and rights in Apache Components are unaffected. Sections 0, 3, 4, 5, 7, 9, 10, 11, 12, 13, 15, and 16 survive termination.

15. Governing law and disputes

This Agreement is governed by the laws of the State of Wyoming, USA, without regard to conflict-of-laws rules, 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. Nothing in this Section 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.

16. General

(a) Export and sanctions compliance. You represent that you are not located in, and will not use or export the Software in violation of, any applicable export-control or sanctions laws (including U.S. EAR and OFAC regulations), and that you are not on any restricted-party or sanctioned-party list.

(b) Entire agreement. This Agreement, together with the Terms of Service, the Privacy Policy, and any terms applicable to a separate purchase presented at checkout, is the entire agreement between you and Qadri LLC regarding the Software and supersedes all prior or contemporaneous understandings.

(c) Severability. If any provision of this Agreement is held unenforceable, it will be limited or eliminated to the minimum extent necessary, and the remaining provisions remain in full force and effect.

(d) Assignment. You may not assign or transfer this Agreement without our prior written consent. We may assign this Agreement, including in connection with a merger, acquisition, reorganization, or sale of assets. Any prohibited assignment is void.

(e) No waiver. Our failure to enforce any provision is not a waiver of our right to do so later.

(f) Force majeure. We are not liable for any delay or failure to perform due to causes beyond our reasonable control.

(g) Notices. We may provide notices to you in-app, by email associated with your account, and/or by posting on tatastu.dev. Legal notices to us must be sent to support@tatastu.dev and to the mailing address in Section 18.

17. Changes to this Agreement

We may update this Agreement. We will communicate material changes in-app, by email, and/or by posting on tatastu.dev with an updated effective date. For material changes, we may require your affirmative re-acceptance; otherwise, continued use after the effective date constitutes acceptance.
