Information we collect

We collect account details you provide, anonymous usage counts, approximate country, device category and time spent. We do not sell personal data.

How tools handle data

Core code and calculator tools process inputs in your browser. Document tools explain their handling before use.

Retention and deletion

Account and security data remains while the account is active. You may request account deletion through Contact Us.

Analytics and country

We use anonymous identifiers and an approximate country code to understand performance. Location is an estimate, not precise tracking.
