Find & Remove Personal Data Before You Share
PrivacyGuard detects SSNs, credit cards, emails, phone numbers, and 12+ PII types in your text. Redact or encrypt — entirely on your device.
Scanner
Paste text, drop files, or scan your iMessage history on Mac. Results filtered by PII type and severity. Export reports for compliance documentation. Batch scan entire directories.
Analyzer
Character and byte frequency analysis with SIMD-accelerated counting. Statistics, word counts, and pattern search. See exactly what's in your data before deciding what to do with it.
Cleaner
Six redaction styles from permanent to reversible. Replace, mask, hash, or encrypt each finding individually. AES-256-GCM encryption lets you recover originals when you need them.
Share Extension
Scan text from any app without switching. Select text in Safari, Notes, or Mail — tap Share, tap PrivacyGuard, and clean it instantly. Redacted text copied to your clipboard.
Custom Patterns
Define your own sensitive data patterns — employee IDs, project codes, medical record numbers. Patterns are encrypted with AES-256-GCM and stored in your device's Keychain.
Export Reports
