Almost nothing. Our calculators run entirely in your browser — the numbers you type never leave your device and are never sent to our servers. We don't ask for your name, email, or account.
We may use basic, privacy-respecting analytics to understand which calculators are popular (page views only). We do not use advertising cookies or cross-site tracking of our own.
If we display ads in the future, the ad provider may use cookies per its own policy. We never sell personal data — we barely collect any.
