Frequently Asked Questions
How does client-side text redaction work?
The redactor uses strict regular expression pattern matchers running locally inside your web browser memory. Matched personal information (PII) is overwritten with black blocks, tokens, or asterisks.
Are my confidential documents uploaded to any AI or cloud server?
No! Redaction happens 100% on the client side in your browser. Not a single character or byte leaves your computer.
Can redacted text be reversed or unmasked?
No. The original text is completely replaced in memory with redaction characters before export, making it impossible for recipients to recover the masked data.
Can I redact specific proprietary names or project code words?
Yes! Use the Custom Keywords input to provide a comma-separated list of names, project code words, or company identifiers to scrub simultaneously.
