Privacy Policy

Last updated: April 2026

Conversion Calculator is built to run on your device. We keep the amount of data we handle as close to zero as possible.

No account

You never create an account. There is nothing to sign up for and nothing to log in to.

Your conversions stay on your device

The values you type and the conversions you make are processed on your device and are not sent to us.

Live currency rates

To show up-to-the-minute currency rates the app fetches exchange-rate data from a rates provider. This request contains no personal information about you. When offline, the app uses the last rates it downloaded.

Analytics

The app and this website may use privacy-respecting, aggregate analytics to understand overall usage. This never identifies you personally.
