What we collect

Nothing you type into the calculator leaves your device. All math runs in your browser. We do not require an account, an email address, or any personal information to use this site.

Analytics

We use privacy-respecting, aggregate analytics to understand how many people visit and which features get used. No individual profiles are built or sold.

Advertising

If ads are shown in the future, third-party vendors such as Google may use cookies to serve ads based on prior visits. You can opt out of personalized advertising at any time via your ad settings.
