Privacy Policy

Data we process

All calculators on this site run entirely in your browser. The numbers you type are never transmitted to our servers, and we do not store your inputs or results.

Cookies and advertising

We do not run advertising on this site and we do not set tracking cookies. No third-party advertising networks, social buttons, fingerprinting scripts or cross-site trackers are loaded.

If we enable optional privacy-friendly analytics, the service used (Plausible) collects only anonymous, aggregate visit statistics and does not set cookies or identify individual users. If our cookie or advertising practices ever change, this policy will be updated before any change takes effect.

Analytics

Analytics is off by default. If enabled, it is privacy-friendly, cookie-free, and used only to understand aggregate traffic trends. We do not build individual profiles and we do not sell personal data.

Your rights

Under the GDPR and CCPA you may request access to, correction of, or deletion of any personal data we hold, and you may object to processing. To make a request, email charon0813@163.com.

Children

This site is not directed at children under 13 and we do not knowingly collect data from them.
