End User License Agreement (EULA)

Cuttle Browser

Last updated: 22 June 2026

This End User License Agreement ("Agreement") is a legal agreement between you and the individual provider of Cuttle Browser ("Operator", "we", "us") for the Cuttle Browser desktop software, including the bundled browser engine, updates, and accompanying materials (the "Software"). By installing or using the Software, you agree to this Agreement. If you do not agree, do not install or use the Software.

This Agreement governs the software license. Your use of our online services is also subject to the Terms of Service, and your personal data is handled as described in the Privacy Policy.

1. License Grant

Subject to your compliance with this Agreement and, for paid features, an active subscription, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, and revocable license to install and use the Software on the number of devices permitted by your subscription tier, solely for your own lawful use.

2. Restrictions

You may not, and may not permit anyone else to:

  • copy (except for a reasonable backup), distribute, rent, lease, lend, sell, sublicense, or otherwise make the Software available to any third party;
  • reverse engineer, decompile, disassemble, or attempt to derive the source code of the Software, except to the extent this restriction is prohibited by applicable law;
  • modify, adapt, or create derivative works of the Software, except as permitted for the bundled open-source components under their own licenses;
  • remove, alter, or obscure any proprietary notices;
  • circumvent, disable, or tamper with license validation, activation, machine binding, integrity, or anti-tampering mechanisms; or
  • use the Software to develop a competing product, or extract our proprietary fingerprinting or anti-detection techniques for redistribution.

3. Activation and Online Validation

The Software requires account-based activation and periodic online validation of your license. The Software may transmit a hardware-derived device identifier and license information to our services for this purpose, as described in the Privacy Policy. If your license is invalid, expired, or not present, paid features (including fingerprint customization) may be disabled and the Software may operate with default behavior.

4. Updates

We may provide updates, including updates to the browser engine, which may be downloaded and installed automatically. Updates are subject to this Agreement unless accompanied by separate terms. We are not obligated to provide updates or to maintain support for any prior version.

5. Ownership

The Software is licensed, not sold. We and our licensors retain all right, title, and interest in and to the Software, including all intellectual property rights. No rights are granted except those expressly stated in this Agreement.

6. Open-Source and Third-Party Components

The Software is built on the open-source Chromium project and includes other third-party and open-source components. Those components are licensed under their own terms, which are provided with the Software and which prevail over this Agreement with respect to those components. Nothing in this Agreement limits your rights under those open-source licenses.

7. User Responsibility and Acceptable Use

You are solely responsible for your use of the Software and for ensuring it is lawful in your jurisdiction and compliant with the terms of any third-party service you access. You must not use the Software for fraud, unauthorized access, distribution of malware, or any unlawful purpose. The acceptable-use provisions of the Terms of Service apply to the Software.

8. Disclaimer of Warranties

THE SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE OR SECURE, OR THAT ANY FINGERPRINT OR ANTI-DETECTION FEATURE WILL PREVENT DETECTION BY ANY THIRD PARTY. YOU USE THE SOFTWARE AT YOUR OWN RISK.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE OPERATOR WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING FROM YOUR USE OF OR INABILITY TO USE THE SOFTWARE. OUR TOTAL LIABILITY UNDER THIS AGREEMENT WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE PRECEDING THREE (3) MONTHS OR USD 50.

10. Termination

This Agreement is effective until terminated. It terminates automatically if you breach it. We may also terminate or suspend the license if your subscription lapses or as permitted by the Terms of Service. Upon termination, you must stop using and uninstall the Software. Sections 2, 5, 8, 9, and 11 survive termination.

11. Governing Law

This Agreement is governed by the laws of the Operator's country of residence, without regard to conflict-of-law rules, subject to any mandatory consumer-protection law applicable to you.
