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 purchase of a Subscription and your use of the tatastu.dev website 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 the Subscription.
- “Subscription” — a paid plan that entitles you to use the Software, sold and billed through our merchant of record.
- “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 Commons on devices you own or control for personal and noncommercial use. An active Premium Subscription additionally grants commercial use and access to the Premium capabilities described at checkout, solely as permitted herein.
2. Plans, subscription, and activation
2.1 Plans. Commons is available without a Subscription. Premium Subscriptions and payments are sold and processed by our payments provider acting as merchant of record (see Section 13). Pricing and billing terms are presented at checkout. Tatastu offers no free trial.
2.2 Automatic renewal. Your Premium Subscription renews automatically at the then-current price for the selected billing period (e.g., monthly or annually) until you cancel. The renewal cadence, price, and cancellation method are disclosed clearly and conspicuously at checkout, and you affirmatively consent to the recurring charge by completing your purchase. You may cancel at any time through the customer portal; cancellation stops future charges and you retain Premium through the end of the current paid period. Commons remains available afterward. Cancellation is available online and is at least as easy as signing up.
2.3 License keys & activation. Your Subscription entitles you to activate the Software on a limited number of devices (the “activation limit”, currently 2). You may free an activation by deactivating a device from within the Software or the customer portal. The Software validates entitlement periodically and may require periodic online re-validation; reasonable offline use is supported.
2.4 Expiry. If your Subscription lapses, is cancelled and reaches the end of the paid period, or payment cannot be collected, the Premium commercial-use grant and Premium capabilities become unavailable, except where this Agreement or applicable law provides otherwise. Commons and Your Content stored locally on your device remain available.
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 Software or your license key to any third party;
(d) share, publish, or circumvent license keys, activation, entitlement checks, or any technical protection 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. You must supply and are solely responsible for your own credentials and account with a supported AI provider (e.g., your Anthropic Claude subscription or API key). 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 entitlement 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. Termination or lapse of your Subscription does not delete Your Content from your device or prevent you from accessing or exporting it locally.
5.2 Entitlement data. You authorize Qadri LLC to collect, store, and process your license key, a device activation identifier, your Subscription status, and the email associated with your purchase for the purposes of validating your license, enforcing the activation limit, providing support, and operating the Service. This processing is described in the Privacy Policy.
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 FOR THE SUBSCRIPTION 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. Billing, refunds, and merchant of record
Subscriptions are sold by our payments provider, Polar, acting as the merchant of record. The merchant of record is responsible for billing, applicable taxes, and processing payments and refunds. We offer a refund within 14 days of your initial purchase. In addition, where the law of your country or state grants you greater or non-waivable refund or withdrawal rights (for example, the EU/UK 14-day right of withdrawal for digital purchases), those rights also apply. Refunds, cancellations, and billing inquiries are processed by the merchant of record per the refund terms presented at checkout. Manage your Subscription through the customer portal.
14. Termination
This Agreement is effective until terminated. It terminates automatically if you materially breach it or the Terms of Service. Ending a Subscription ends Premium rights but does not terminate the Commons 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 the terms 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 17.
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.
