Frequently asked questions
How fresh are the rates?
We call two public APIs every time you open the converter. If neither responds, we display the last known rate timestamp so you can verify with your bank.
Do you store my currency data?
No. Inputs remain in your browser. Only anonymized conversion metadata is cached for 6 hours to limit API calls.
