Plainly stated
What we do and don't collect.
Here is the whole privacy picture, including the data the app does collect.
Read the privacy policy- Your calculations stay on your device. Inputs are never transmitted.
- No ads and no ad SDKs. The app contains no advertising SDK.
- No account required. The app works without registration.
- We never sell your data. There is no advertising data business.
- We do collect anonymous usage and crash data. That includes which screens open, which tools are used, and what crashed — never the numbers you type.
That last line is why we don't claim "zero tracking". Anonymous analytics and crash reporting are declared in our App Store privacy label and Play Data Safety form. You can turn them off in Settings.
