Your calculations stay in your browser
All calculations run in your browser. The amounts and options you enter are not sent to our server. We save your last calculation and your light or dark mode preference on your device, using your browser’s local storage. To remove them, clear this site’s data in your browser.
When you share a calculation, the link contains the amounts you entered. Anyone with that link can view the calculation.
Hosting and exchange rates
The website runs on the Cloudflare network. Cloudflare processes technical data, such as your IP address, to run the site and block attacks. Our server fetches the exchange rates from the European Central Bank without passing on any data about you.
Advertising
Google AdSense ads pay for the site. Google and its partners may use cookies and similar techniques to show and measure ads and, if you consent, to tailor them to your interests.
On your first visit we ask for your consent through a message from Google. If you don’t consent, you only see non-personalised ads. You can change your choice at any time:

Your rights
Under the General Data Protection Regulation (GDPR) you have the right to access, correct or delete your data and to object to its processing. As we don’t store data about you ourselves, you will usually have to ask Google or Cloudflare. You can also complain to the data protection authority of your country; see the list of EU data protection authorities.
