Is the generated data real?

No. Identity and user records are explicitly synthetic test fixtures. Other output is generated from local templates or algorithms.

Is my input uploaded?

No. The website tool runs locally in your browser. Input is sent only when you intentionally call the authenticated API.

Can I use the output in production?

Review it first. CAPTCHA answers must be hashed and verified server-side, synthetic identities must remain test data, and generated names require trademark checks.
