What data we collect
The calculators themselves run entirely in your browser โ the numbers you enter (such as weight, loan amount or age) are never sent to our servers. We do collect standard website analytics (anonymized visit statistics) and data you voluntarily submit through forms (for example your email address for a contact request or newsletter signup).
Cookies
We use functional cookies (for example to remember your language and theme preference) and, where applicable, analytics cookies. See our Cookie Policy for the full overview.
Third-party services
For live rate data we use the public APIs of CoinGecko (cryptocurrency) and Frankfurter/ECB (exchange rates). These services do not receive any personal data from you through our calculators โ the requests are for aggregated rate information, not tied to your input.
Your rights
Under GDPR you have the right to access, correct and delete your personal data, and the right to object to processing. Contact us at mijnrekenmachine@gmail.com to exercise these rights.
Changes
We may update this privacy policy from time to time. The date at the top of this page indicates when it was last changed.
