Question 1

Is this safe for sensitive data?

Accepted Answer

All processing happens in your browser. No fetch/XHR calls with your text, no localStorage, no analytics. The live network counter on the page tracks outbound requests in real time.

Question 2

What does the redactor detect?

Accepted Answer

Four high-confidence categories: emails, API keys (OpenAI, Anthropic, AWS, GitHub, Google, Stripe, Slack), Luhn-validated credit cards, and phone numbers (heuristic, marked Possible).

Question 3

Why don't you redact names or addresses?

Accepted Answer

Name and address detection has high false-positive rates. We prefer to redact 4 categories reliably than 10 unreliably.

Question 4

Can I use it offline?

Accepted Answer

Yes. Once loaded, the page works fully offline — open DevTools Network tab, set Offline, type, and redactions still work.
