Pure Trace · Terms of Service

1. Acceptance & Changes

Before downloading, installing, or using Pure Trace (the "App"), please read this agreement carefully. By using the App you accept it in full; if you disagree, please stop using it. The agreement may change as the App evolves — material changes will be announced on this page with a new effective date, and continued use means you accept the updated agreement.

2. Service & License

Pure Trace is a software product developed and maintained by an independent developer.

Subject to your compliance with this agreement, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control. We keep improving the App; features may change between versions, and important changes are noted in the changelog.

3. Accounts

Pure Trace requires no account. If you use system-provided services such as cloud sync, that provider's terms also apply to the data involved.

4. Acceptable Use

You agree to use the App lawfully, to ensure that content you enter or import is lawful, and not to use the App for any illegal or infringing activity. You will not reverse engineer or decompile the App, copy or modify it or create derivative works, rent, resell, or redistribute it without authorisation, or bypass its technical limits, membership restrictions, or purchase mechanisms.

5. Intellectual Property

Except for content you create or lawfully own, the App — including its code, interface, icons, copy, and design — is owned by the developer. You may not copy, modify, reverse engineer, sell, or redistribute it without authorisation. Content you create or import remains yours or your licensors'; we claim no ownership over your data.

6. Disclaimer of Warranties

The App is provided "as is". We keep improving it, but to the extent permitted by law we make no promises that it will meet your particular needs, run uninterrupted, timely, securely, or error-free, or that the data it presents is fully accurate or reliable. You are responsible for regularly backing up data you create with the App; we are not liable for losses caused by failure to back up.

7. Limitation of Liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, punitive, or consequential damages (including data loss, business interruption, or lost profits) arising from use of or inability to use the App, even if advised of the possibility. Our total liability for the App or this agreement is capped at what you actually paid for the App in the past 12 months (zero if you paid nothing).

8. Changes & Termination

You can stop using the App anytime by deleting it; local data on your device remains yours and can be exported with the app's export features. If an app must be discontinued, we will announce it in the app or on this page ahead of time and provide a data-export path where possible. If you breach this agreement, we may limit or suspend your use of the relevant services or features.

9. Governing Law & Disputes

This agreement is governed by the laws of the People's Republic of China. Disputes shall first be resolved amicably; failing that, either party may bring suit before a court of competent jurisdiction.
