Frequently Asked Questions

No. All data is randomly generated on the client side and is entirely fictional. Names, emails, phone numbers, and addresses are constructed from random parts and do not correspond to real people or places. Fake credit card numbers do not pass Luhn validation and cannot be used for transactions.

Yes! This tool is designed for generating test fixtures, populating development databases, creating mock API responses, and similar testing scenarios. The data is random but structured to look realistic.

UUIDs are generated using the crypto.getRandomValues API in your browser, producing version-4 UUIDs (random). These are cryptographically random and have an extremely low probability of collision.

The credit card numbers are generated with random digits and do not follow the Luhn algorithm used by real card issuers. They are intentionally non-functional and are meant only for UI testing and form validation development.
