Is my text data secure during processing?

Yes, absolutely. All text anonymization happens entirely in your browser using JavaScript. Your text is never sent to any server or stored anywhere, ensuring complete privacy and security of your sensitive information.

How accurate is the detection of personal information?

The tool uses proven regex patterns to detect common formats of personal data including standard email formats, phone number patterns, credit card validation, SSN formats, IP address ranges, and URL patterns. It minimizes false positives while catching real instances of sensitive data.

What happens to names and addresses detection?

Name and address detection uses conservative patterns to avoid false positives. Names are only detected in specific contexts (two consecutive capitalized words), and addresses follow common street address formats. You can disable these if they're not needed for your use case.

Can I customize what gets anonymized?

Yes, the tool provides granular control over privacy protection. You can choose which types of data to protect (emails, phones, credit cards, etc.) and whether to replace them with placeholders or remove them entirely.

Does the tool work with non-English text?

The tool primarily works with standard English formats for personal data. Some features like email and URL detection work internationally, but phone numbers, addresses, and names are optimized for US/English patterns.

What does [EMAIL REDACTED] format mean?

The tool replaces sensitive data with clear, descriptive placeholders like [EMAIL REDACTED], [PHONE REDACTED], [CARD REDACTED], etc. This makes it obvious what type of information was removed while protecting the actual data.
