Frequently Asked Questions
Are the credit card numbers real?
No. All generated credit card numbers and financial details follow official testing formats (like Stripe test cards). They cannot be used for real transactions.
Is this data safe to use in my database?
Yes, the data is entirely fictional and randomly generated using the open-source Faker library. It is perfect for seeding development or staging databases without violating privacy laws like GDPR.
How is the data generated without a backend?
The tool imports the `faker.js` engine directly into your browser. When you click generate, all localization, randomization, and formatting happen instantly using your computer's CPU, ensuring absolute privacy.
