Terms & End-User License Agreement

This is the licence agreement that governs your use of Tyfold. See also our Privacy Policy.

PROPRIETARY AND CONFIDENTIAL. This software is a commercial, closed-source product. It is licensed, not sold. No open-source license (MIT, Apache, GPL, or any other) applies to it, and nothing in this repository's history grants one.

IMPORTANT — read before installing or using Tyfold ("the Software"). By downloading, installing, or using the Software you ("you", "the Licensee") agree to be bound by this Agreement. If you do not agree, do not install or use the Software.

1. LICENSE GRANT

Subject to your compliance with this Agreement and, where applicable, payment of the subscription fee, Tyfold ("the Licensor") grants you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Software on devices you own or control, for your own internal or professional use. That license covers the Software's free tier for as long as the Licensor offers one, and any subscription-only features for the duration of a valid trial or paid subscription.

2. FREE TIER, SUBSCRIPTION AND TRIAL

The Software is offered with a free tier and a paid subscription, and the Licensor may also offer a free trial period. Access to some features may be conditioned on an active subscription or trial. The Licensor may define, change, or discontinue the free-versus-paid feature split, pricing, the free tier, and trial terms at any time; the terms in effect at the time of your purchase govern that subscription period. When a trial or subscription ends without renewal, your license to use the corresponding paid features ends, and any free tier then on offer remains available to you.

3. RESTRICTIONS

You may NOT, in whole or in part: (a) copy, redistribute, publish, sell, rent, lease, lend, sublicense, or otherwise make the Software available to any third party; (b) reverse-engineer, decompile, disassemble, or otherwise attempt to derive the source code, except to the limited extent this restriction is expressly prohibited by applicable law; (c) modify, adapt, translate, or create derivative works of the Software; (d) remove, alter, or obscure any copyright, trademark, or other proprietary notices; (e) circumvent, disable, or interfere with any license-enforcement, activation, or subscription-validation mechanism; (f) use the Software to build or assist a competing product.

4. BRING YOUR OWN CREDENTIALS; NO RESALE OF MODELS

The Software is a client that drives your own large-language-model command-line tools (for example, Claude Code) under your own provider credentials. The Licensor does not host, provide, or resell any language model, and is not responsible for your provider accounts, credentials, usage, or charges. Your use of any third-party model or service is governed by that third party's terms.

5. OWNERSHIP

The Software is licensed, not sold. The Licensor retains all right, title, and interest in and to the Software, including all intellectual-property rights. No rights are granted to you except as expressly stated here.

6. THIRD-PARTY MARKS

Tyfold is an independent, unaffiliated product. "Claude" and "Claude Code" are trademarks of Anthropic, PBC; Tyfold is not endorsed by, sponsored by, or affiliated with Anthropic. All other trademarks are the property of their respective owners. References to such marks are nominative, to describe interoperability only.

7. DISCLAIMER OF WARRANTY

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. THE LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED OR ERROR-FREE. Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you, and you may have statutory rights that this Agreement does not affect.

8. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE LICENSOR SHALL NOT 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 THE SOFTWARE OR THIS AGREEMENT. THE LICENSOR'S TOTAL AGGREGATE LIABILITY SHALL NOT EXCEED THE AMOUNTS YOU PAID FOR THE SUBSCRIPTION IN THE TWELVE MONTHS PRECEDING THE CLAIM. Nothing in this Agreement limits liability that cannot be limited under applicable law.

9. TERMINATION

This Agreement is effective until terminated. It terminates automatically if you breach any of its terms, and the Licensor may terminate it on notice. On termination you must stop using the Software and remove all copies. Sections 3, 5, 6, 7, 8, and 10 survive termination.

10. GOVERNING LAW

This Agreement is governed by the laws of the Licensor's place of establishment, without regard to conflict-of-laws principles, and subject to any mandatory consumer-protection rights of your country of residence.
