What We Collect

Nothing. We don't collect personal information, require accounts, or use cookies. Our calculators run entirely in your browser.

Any numbers or values you enter into our calculators stay on your device. We don't send, store, or track your inputs.

We don't share data with third parties because we don't have any data to share.

If we ever change this policy, we'll update this page.
