Frequently asked questions

Is source text sent to a server?

No. Detection, replacement, hashing and reports run in the browser.

Can a clean scan prove there are no secrets?

No. Checks can miss unfamiliar formats or flag harmless values; review context.

Do reports include detected values?

No. Reports include only type, severity, location, length and confidence.

Are custom regular expressions risk-free?

No. Invalid and oversized patterns are rejected, but complex patterns can still be expensive.
