Why do I have to enter the exchange rate myself?

This tool runs entirely client-side with no server and no external API calls, so it can't fetch a live rate. Enter the rate from your bank, card provider, or a rate lookup, and the conversion math runs instantly and privately in your browser.

Where can I find today's exchange rate?

Your bank's app, a currency exchange website, or a quick web search for "[currency A] to [currency B]" will show a current rate you can enter here.

What does the Swap button do?

It flips the from/to currency codes and inverts the rate (1 ÷ rate) so you can convert in the opposite direction without retyping the rate.

Is my amount or currency data sent anywhere?

No. All calculations run locally in your browser with JavaScript — nothing is transmitted or stored.
