Privacy policy
Last updated: October 15, 2026
Your entries and photos
What you enter in the calculator, your receipt photos and your language choice are stored only on your device (your browser's localStorage and IndexedDB). They are never sent to our server, and we cannot see them.
You can remove them with the calculator's “Clear all” button, by deleting photos, or by clearing this site's data in your browser.
Exchange rates
To show converted amounts, your browser requests rates from Frankfurter, a service that publishes European Central Bank reference rates. Frankfurter receives connection information such as your IP address, but none of the amounts you enter.
Advertising and cookies
This site uses Google AdSense, a third-party advertising service. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
You can opt out of personalized advertising in Google's Ads Settings, and opt out of other third-party vendors' cookies at aboutads.info. Visitors from the European Economic Area, the UK and Switzerland are asked for consent to the use of cookies.
Access logs
For operation and security, the server records IP addresses, access times, requested pages and browser types. We don't use them to identify individuals, and they are deleted after a limited period.
Changes
We may update this policy as needed and will publish changes on this page.
