Private by design
The IBAN you enter
stays here.
IBANChopper is built as a browser-local utility. The number you enter is used in memory to calculate your result, then it is gone when you leave or reload the page.
Processed locally
Validation happens in your browser. The entered IBAN is not transmitted to IBANChopper servers or a validation API.
Not stored
We do not put IBANs in databases, cookies, localStorage, sessionStorage, URLs, logs, or analytics events.
No sign-in required
No sign-in or user account is required. There is no upload or automatic clipboard reading in the secure tool.
No trackers in the tool
This initial version has no analytics or advertising scripts. It is intentionally a small, focused experience.
