Privacy Policy

To understand which calculators are useful, we keep anonymous, aggregated usage counts on our own servers — for example which calculator was used and whether the calculation completed successfully. This information contains no personal data, sets no cookies, and is not linked to your IP address.

Calculator inputs are not stored. Server logs are retained for a maximum of 30 days for security purposes and then deleted.

We do not sell, trade, or share user data with third parties.

You have the right to request information about any personal data we may hold, request correction or deletion, and object to processing. Contact us at info@taxengine.ch.
