Privacy

Short version: FormulaCheck analyzes your formulas inside your browser. We do not receive them.

Your formulas

Anything you type or paste is processed by code running in your browser tab. It is not sent to our servers, stored or shared. Closing the tab discards it.

What we do collect

The web host may keep standard server logs (such as IP address, page requested and time) for security and reliability. FormulaCheck may use privacy-friendly, cookie-free analytics to count page visits. These tools never receive the formulas you enter.

Third-party resources

The page loads fonts from Google Fonts, which can see that your browser requested them, as with any website that uses them.

Cookies

FormulaCheck does not set cookies of its own.
