What we collect

If you use calculators without signing in, we collect nothing beyond standard server access logs (IP, user-agent) used only for security and abuse prevention. Calculator inputs are processed on the server for the single request and are never stored.

If you create an account, we store your name, email, and password (hashed with bcrypt). If you choose to save a calculation, its inputs and results are linked to your account until you delete them.

Cookies

We use one session cookie to keep you logged in and a CSRF token for form security. We do not use third-party tracking cookies unless you have explicitly consented via our cookie banner.

Ads

We may display ads via Google AdSense. AdSense may use cookies to personalise ads. You can opt out at adssettings.google.com.
