What exchange rate does this tool use?

The rate field is pre-filled with a reference rate refreshed hourly from a public rate feed, and the page shows when it was last updated. You can still overwrite it with a figure from your bank, broker, or a financial data provider before making financial decisions.

Is my data sent to any server?

No. All calculations happen locally in your browser using JavaScript. Nothing is transmitted to Top10k or any third party.

Why does the rate differ from my bank?

Banks and currency exchanges apply a spread (markup) on top of the mid-market rate. The default shown here is the approximate mid-market rate; your bank's buying or selling rate will be slightly different.

Can I convert USD back to CZK?

This page converts CZK to USD only. For a manual reverse conversion, divide the USD amount by the displayed USD-per-CZK rate.

How often should I update the rate?

For travel estimates, once per day is usually sufficient. For business or financial transactions, check the rate just before you transact, as CZK/USD can move noticeably during the day.
