About

Anonymize IDs and sensitive text locally in your browser — customizable regex patterns, exportable mappings, no server uploads.


Local Text Anonymizer safely anonymizes identifiable text (IDs like patient IDs/numbers, or other patterns) directly in your browser. The extension runs entirely locally — nothing is sent to any server. Use customizable regular-expression patterns to detect text in inputs and textareas; matches are replaced with stable pseudonyms so you can share or store text without exposing original identifiers. Mappings (original → replacement) are stored locally in your browser and can be exported, imported, or reversed (de-anonymized) from the popup.


Key features
- Local-only processing — no network calls, privacy-preserving.
- Custom regex patterns: add or remove patterns to fit your data.
- Live replacement in text inputs and textareas as you type or paste.
- Manual anonymization and de-anonymization tools in the popup.
- Export and import JSON mappings for reproducible anonymization across sessions.
- Minimal, developer-oriented prototype for testing and integration.


How to use
- Open the popup, add or accept the default pattern (e.g., ID[0-9A-Z]+).
- Click "Apply" to anonymize text in inputs/text-areas or use the manual anonymize tool.
- Export the mapping to save replacement pairs; re-import to restore the same anonymization.
- Use de-anonymize to reverse replacements when needed.

Privacy
All processing and mapping storage happen in chrome.storage.local on your machine. No data leaves your browser.
