License agreement

The terms for using Sidehand. In short: a personal license for the computers your plan covers; no copying, sharing or reverse engineering; and nothing leaves your computer. Last updated 1 November 2026.

This agreement is between you and the publisher of Sidehand named in the Terms of sale ("we", "us"). By installing or using Sidehand ("the Software") you accept it. If you do not accept it, do not install or use the Software.

1. OWNERSHIP. The Software is licensed to you, not sold. The copyright and all other rights in the Software, including its source code, belong to us. This agreement gives you only the rights it states.

2. LICENSE. After purchase, we grant you a non-exclusive, non-transferable license to use the Software under the plan you bought: - Solo: one computer, one agent working at a time. - Crew: one computer, up to three agents working at the same time. - Fleet: up to three computers, Windows and Mac in any mix, up to five agents working at the same time on each. Solo and Crew are for the platform (Windows or Mac) you bought them for. The license may be used by you or, if a business bought it, by its staff, within these limits. A license includes the updates released during the period stated at purchase; versions released in that period may be used forever. Every license is registered to the account that bought it. When you upgrade to a bigger plan, the new license replaces the old one.

3. RESTRICTIONS. You may not, and may not let anyone else: (a) copy the Software, except to install it on the computers your plan covers and to keep one backup copy; (b) share, sell, rent, lend, sublicense or publish the Software or a license key, or let people outside your plan use them; (c) decompile, disassemble or reverse engineer the Software, or try to obtain its source code, except where the law expressly allows this despite this restriction (for example to make it work with other software under EU Directive 2009/24/EC), and then only as far as the law allows; (d) modify the Software or create works based on it; (e) remove or bypass the license check, the update signature check, any copy protection, or the safety features (read-only protection, on-screen confirmation, overwrite protection, app locking and pinning, parking, the kill switch, idle-time input borrowing); (f) use the Software, its code, or knowledge gained from examining it, to build or help build a competing product; (g) remove or change copyright, trademark or license notices.

4. ACCEPTABLE USE. You must use the Software lawfully and in line with the Sidehand Acceptable Use Policy. In particular you may not use it to access computers, accounts or data without permission; to monitor or record other people without their consent; to defeat security measures, CAPTCHAs or anti-automation controls; or for fraud, spam, impersonation or harassment.

5. YOUR RESPONSIBILITY. The Software lets AI agents operate applications on your computer. You decide which agents, AI apps and models use it and what they are asked to do. You are responsible for their actions, for complying with the terms of the applications and services they use, and for keeping backups of your work. The Software does not include any AI model or AI service: the AI apps and providers you connect are governed by their own terms and charges. Keep the kill switch in mind.

6. PRIVACY AND UPDATES. The Software runs locally. It does not send screenshots, typed text, or usage data to us. To check your license, the Software sends your license key, a scrambled computer identifier and a name for the computer to our server when you connect a computer and with the daily check, including when update checks are switched off; between checks it works offline for up to 30 days. Unless you switch it off in settings, the Software checks once a day for a newer version by downloading a signed file; that check sends no information about you or your use of the Software. Updates are installed only after their signature and checksum have been verified.

7. PURCHASES AND REFUNDS. Purchases are governed by the Terms of sale. Once the download of your order has started, the sale is final, except for your legal rights if the Software does not work as described. When an order is refunded or its payment is reversed, the license for that order ends.

8. TERMINATION. This license ends automatically if you break it, including the Acceptable Use Policy. When the license ends, for any reason, you must stop using the Software and delete every copy, and we may revoke the license key. A license that ends because you broke it is not refunded. We may claim compensation for the damage a breach causes.

9. TRADEMARKS. "Sidehand" and the Sidehand logo are our trademarks. This agreement grants no right to use them except to refer to the Software. Other names and products mentioned (for example Claude, ChatGPT, Gemini, Cursor, VS Code, Windsurf, Windows and macOS) are trademarks of their respective owners; the Software is not affiliated with or endorsed by them. See Trademarks.

10. NO WARRANTY. TO THE EXTENT PERMITTED BY LAW, THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. AI agents can make mistakes; review their work. Nothing in this agreement limits your rights as a consumer under the law of the country where you live, including the legal guarantee described in the Terms of sale.

11. LIMITATION OF LIABILITY. TO THE EXTENT PERMITTED BY LAW, WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, OR LOSS OF DATA, ARISING FROM THE USE OF THE SOFTWARE. OUR TOTAL LIABILITY IS LIMITED TO THE AMOUNT YOU PAID FOR THE LICENSE.

12. THIRD-PARTY COMPONENTS. The Software includes open-source components under their own licenses, listed in THIRD_PARTY_NOTICES.txt.

13. GOVERNING LAW. This agreement is governed by Portuguese law. If you are a consumer, you keep the protection of the mandatory consumer laws of the country where you live.
