Overview

Replaces sensitive patterns with placeholders and enables back-translation, while keeping all data locally.

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.
