Privacy Policy

Last updated: January 2024

Data Collection

All calculators on this site run locally in your browser. We do not collect, store, or transmit any calculation data you enter.

Access Logs

Our servers may record basic access logs (IP address, access time, page path) for site maintenance and security. These logs are not associated with personal identity information.

Cookies and Analytics

The calculator features do not rely on login cookies. We use self-hosted analytics and Baidu Analytics to understand traffic, referrers, device, and browser performance. These statistics are used for page quality review, troubleshooting, and site improvement, not to collect the calculation data you enter.

Third-Party Services

Baidu Analytics loads a script from hm.baidu.com and may record aggregate page visit, referrer, device, and browser information. Our self-hosted analytics script is served from stats.jtlcookie.com. We do not send calculator inputs, passwords, or contact messages to these analytics services.
