Privacy policy

Last updated October 27, 2026

Tender does not collect, store or share any personal data. It has no accounts, no analytics, no advertising and no tracking, and it contains no third-party SDKs.

What stays on your phone

Your settings, favorites, recently used currencies and the most recent set of exchange rates are saved only on your device. They are never sent anywhere. Deleting the app deletes them.

Exchange rates

To get current rates, Tender requests the day's rates from Exchange Rate API (open.er-api.com). The request asks for the full rate table and contains nothing about you, your amounts or your currencies. Like any web server, Exchange Rate API's server receives your IP address and basic request details when it answers. Their handling of that is covered by their terms and privacy policy.

This website

This site has no cookies, analytics or trackers. It is hosted on Vercel, which keeps standard server logs, such as IP addresses, for security and operations.

Children

Tender collects no data from anyone, including children.

Changes

If this policy changes, the new version will be posted here with a new date.
