자주 묻는 질문
How often are the exchange rates updated, and where do they come from?
This currency converter refreshes once a day from live mid-market reference rates, with two independent sources for reliability: it tries open.er-api.com first and falls back to the European Central Bank (via Frankfurter). The reference date is always printed under the result, so you can see exactly how current the exchange rate is.
Why is the amount my bank or card shows different from this?
This exchange rate calculator uses the mid-market rate — the midpoint between the buy and sell price, the "real" rate you see on Google or Reuters. Banks, cards and money-transfer apps add a spread and fees on top, so their USD to EUR or USD to INR amount is usually a little worse. Use this number as the fair baseline to judge their offer.
What rate does it use when I'm offline or a source is down?
It never leaves you with a blank screen. If both live sources fail, it falls back to the last rate saved on your device (cached for 24 hours), and if there's none, to a built-in snapshot bundled with the app. Whenever the number isn't live, a clear "Not live — using a saved rate" warning and a Retry button appear, so you're never misled.
Are these live, real-time trading rates?
No — and no free tool should claim to be. These are daily mid-market reference rates, fine for shopping, travel budgets and money transfers. They are not tick-by-tick trading rates, so don't use them for FX dealing or large, time-sensitive transfers.
Is my amount sent to a server?
No. Only the exchange-rate table is fetched; every conversion runs locally in your browser. Nothing you type is uploaded, stored, or shared — no account, no tracking, and it keeps working offline from saved rates.
