Privacy Policy
Last updated: 2026
The short version
Sawdust Math is a set of free calculators. All calculations run in your browser — the numbers you type into a tool are never sent to our servers.
What we collect
We use privacy-respecting, aggregate analytics to understand which tools people use (page views, country, browser type). This data is not tied to your identity.
Advertising
We do not currently run advertising on this site. If that changes, this policy will be updated first, including full disclosure of the ad partners involved and the choices available to you.
If you email us, we use your address only to reply. We don’t add you to lists or share it.
