Privacy

Your contract numbers never leave your device. Every calculator on KeepMyCheck runs inside your own browser. We do not ask for your name, email, or phone to use it, and we do not save what you type.

If you use the share button, the numbers go into the link itself so the person you send it to sees the same result. Only share that link with people you trust.

Like almost every website, our host keeps basic server logs (such as the page requested and a browser type) to keep the site running and secure. We may use privacy-friendly analytics to count visits to pages. We never sell data, and we have no agents or advisors buying leads from us.

Some pages show ads for other free or paid sites. Clicking one takes you to that site, which has its own privacy policy.
