Terms of Service

Effective: October 20, 2026 · Last updated: October 20, 2026

These terms are an agreement between you and clat.ai for downloading, installing and using the clat.ai app and related services. By downloading or using the app, you agree to these terms. If you do not agree, do not install or use it.

1. License grant

After purchase, we grant you a personal, non-exclusive, non-transferable license to install and use clat.ai on up to 2 Macs that you own or control. The license is for personal use or internal use within your organization. You may not resell, rent, share the key or use it to provide a service to others.

2. Free trial

Without a license, you can try cleaning, uninstalling and optimization 2 times each. Trial counts are tracked per tool and are not reset by reinstalling. We may adjust trial limits, but will not retroactively reduce the rights of paid users.

3. Price, payment and refunds

4. Updates and support

We provide updates and bug fixes within the current product line, but do not guarantee support for every macOS version or every feature indefinitely. Older versions may stop working as system interfaces change. We may add, modify or remove features.

5. Restrictions

You agree not to:

6. Your responsibilities and data

Cleaning deletes files. User-level items go to the Trash and can be restored in Finder; system-level items and "clean permanently" cannot be undone. Review your selection and keep backups of important data.

7. Disclaimer

The software is provided "as is". To the maximum extent permitted by law, we disclaim all express or implied warranties, including merchantability, fitness for a particular purpose and non-infringement, and do not warrant that the software will be error-free, uninterrupted or fix every issue. Some features depend on macOS version, hardware and system permissions, and results may vary.

8. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special or consequential damages (including data loss, lost profits or business interruption) arising from the use of or inability to use the software. Our aggregate liability under these terms will not exceed the amount you actually paid for the license.

Nothing in this section excludes or limits liability that cannot be excluded by law, or affects your statutory rights as a consumer.

9. Termination

If you breach these terms, we may suspend or terminate your license. You may stop using the software and delete it at any time; refunds are handled under Section 3.

10. Governing law and disputes

These terms are governed by the laws of the People's Republic of China, excluding conflict-of-law rules. The parties will first try to resolve disputes amicably; if that fails, the dispute will be submitted to the competent court where the operator is located. Mandatory consumer protection rules in your region are not affected.

11. Changes

We may update these terms and will post a new effective date on this page. Material changes will be communicated through the website or app within a reasonable period. Continued use after changes means you accept them.
