Personal Keyword Blocker EN

Personal Keyword Blocker is a private local keyword-blocking extension for people who want more friction around distracting or triggering browsing patterns. It lets users create their own blocked-term lists and block matching URLs, search pages, page titles, typed text, form submissions, and optionally visible page text.

The extension is designed around local processing. Blocked terms and settings are saved in browser extension storage. Matching happens inside the browser. The developer does not receive blocked terms, browsing history, page content, typed input, form text, page titles, settings, or match results.

Core features:
- Create a Normal Block List with strict word-boundary matching
- Create a Max Security List for broader root-term matching
- Block matching URLs and search queries
- Block matching page titles
- Block matching typed text and form submissions
- Optionally scan visible page text
- Catch common bypass patterns such as separators, URL-encoded separators, accent variants, plurals, possessives, action forms, and common number/symbol substitutions
- Preview and test blocked terms before saving
- Import and export settings for backup
- Use append-only locked mode so existing terms cannot be removed or weakened through the extension UI
- Store settings locally in the browser profile, with sync/fallback behavior through browser extension storage where available

Personal Keyword Blocker is a friction tool, not a guarantee of permanent control. It is designed to slow down impulsive browsing choices and make it easier to stay with the user’s intended browsing rules.

The extension does not use a developer-operated backend server. It does not use analytics, advertising, telemetry, data selling, or remote code.
