Privacy Policy

Your numbers never leave your device. Both calculators run entirely in your browser using JavaScript. We do not collect, transmit, or store anything you type.

We do not use accounts, and we do not sell data — because we don't have any. If we add analytics in the future, it will be privacy-respecting and disclosed here.

Third-party links (e.g., our Etsy shop) are governed by their own privacy policies.
