Frequently asked questions
Are the exchange rates live?+
No. They are an editable offline snapshot. For real transactions, update the rates from your bank or a market source first.
Why offline rates instead of an API?+
It keeps the tool private and usable without internet, and lets you lock in the exact rate you want to plan around.
Do my edited rates persist?+
Yes. Changes are saved in your browser and restored next time. Use “Reset to snapshot” to revert.
Is my data sent anywhere?+
No. Everything stays in your browser.
