Question 1

Where do the exchange rates come from?

Accepted Answer

Rates come from a public API providing European Central Bank (ECB) reference rates. Actual bank transfer or exchange rates may differ.

Question 2

How often are the rates updated?

Accepted Answer

Rates update once per business day (around 4pm Central European Time). Weekends and holidays show the previous business day's rate.

Question 3

Does this match actual bank exchange rates?

Accepted Answer

No. This shows a reference rate for comparison — actual bank exchanges apply fees and preferential rates that differ from this value.

Question 4

Which currencies are supported?

Accepted Answer

12 major currencies including KRW, USD, EUR, JPY, and CNY.

Question 5

Is my amount sent to a server?

Accepted Answer

No. Only the rate data is fetched from an external API — the calculation itself happens entirely in your browser.
