Question 1

Where do the exchange rates come from?

Accepted Answer

Rates are fetched from ExchangeRate-API's free, no-key endpoint (open.er-api.com), which refreshes once every 24 hours.

Question 2

Is my amount sent to a server?

Accepted Answer

No, only the exchange rate table is fetched; the conversion itself happens locally in your browser.

Question 3

Why does it say the rate is cached?

Accepted Answer

Rates are stored in your browser for 24 hours to avoid refetching on every visit, matching how often the source updates them.

Question 4

Can I force a fresh rate fetch?

Accepted Answer

Yes, use the refresh button to bypass the cache and pull the latest available rates.

Question 5

Are cryptocurrencies supported?

Accepted Answer

No, only official fiat currencies published by the rate provider are supported.
