Privacy Policy

Last updated: 22 October 2026

What we collect

If you create an account, we store your email address and a securely hashed password (we never store your password itself). If you save a flip calculation, we store the numbers you entered and the result.

What we don't collect

We don't collect unnecessary personal information during registration, and we don't run invasive tracking or third-party advertising analytics. We record a small number of anonymous internal usage events (such as when a calculation is completed) to understand how the tool is used.

How we use your data

Your data is used to provide the calculator, dashboard and saved-flip features, and to keep your account secure.

Data retention

Your saved calculations remain in your account until you delete them or close your account.
