FAQ
Frequently asked questions about the toolbox: privacy, how scores work, why results differ.
FAQ
Do the tools collect my data?
Most tools (JSON, Base64, QR codes, image compression, regex, word counter, UUID, hashing, WebRTC test, browser fingerprint, address generator…) run entirely in your browser — your input never leaves your device. See the privacy policy for the few server-assisted checks.
How is the purity score calculated?
It is a weighted heuristic: datacenter/hosting +45, proxy traits +30, known cloud ASN +20, mobile -10, mapped to a 0-100 purity score. ≥80 is high purity, <40 is high risk. It is a reference signal, not an authoritative verdict.
Why does my IP show as datacenter / high risk?
If you browse through a VPS, cloud server or proxy node, the egress IP is inherently datacenter property — that's normal and doesn't affect everyday browsing, though sensitive services may apply extra scrutiny on sign-up.
Why does the streaming unlock result differ from what I can actually watch?
The check is performed by this server (US exit) against each service. It reflects the IP's "reachability"; the actual playable catalog can still vary by account and region. Treat it as a reference.
Are generated addresses / passwords / QR codes uploaded?
No. Generators and converters run entirely in the browser — try them offline. Address data is randomly fictional; do not use it as a real identity.
Are there rate limits?
Yes — see the API docs. Exceeding them returns 429 for a short while.
