About this extension
Site Blocker & Time Tracker helps you take back your focus. It combines a powerful site blocker with a private time tracker: block distractions and see where your time really goes. Everything stays on your device: no accounts, no servers. The extension is free.
BLOCK DISTRACTIONS
- Distraction-Free Mode: one toggle blocks the main social media and doomscrolling sites (YouTube, Instagram, TikTok, Facebook, X, Reddit, Twitch, Netflix and more) without touching your personal blocklist.
- Anti-Shorts & Reels: block short-form video on YouTube Shorts, Instagram Reels, TikTok and Facebook Reels.
- Mindful Pause: a guided breathing screen and a 10-second countdown before you decide whether to continue.
- Custom Blocklist: add or remove sites and subdomains in one click.
UNDERSTAND HOW YOU SPEND YOUR TIME
- Real-time tracking: live timer for the active tab and your daily total.
- 24-hour timeline: see when and where you spent your time.
- Productivity categories: tag sites as Productive, Neutral or Distracting.
- Trends and insights: 7-day history, daily averages and the sites that eat most of your time.
- Idle detection: tracking pauses when you lock your screen or step away.
PRIVACY BY DESIGN
- All data stays in your browser. Nothing is sent anywhere.
- Zero analytics, telemetry or third-party scripts.
- Only the domain is stored (e.g. youtube.com), never full URLs, typed text, passwords or cookies.
- Full export and backup/restore of your data (JSON/CSV).
- The site-blocking core is open source: the code of the base version is public on GitHub: https://github.com/Semplicementeio/Site-Blocker
WHY IT'S DIFFERENT
Many free extensions make money from your data: they collect your browsing history, sell it to third parties and build profiles of their users. Site Blocker & Time Tracker does none of this. It has no analytics, no telemetry, no remote servers and makes no external network requests.
FEEDBACK
Site Blocker & Time Tracker is an independent project and I listen to everyone. If a feature is missing or something doesn't work the way you'd like, write to me at luca@semplicemente.io.
If you find the extension useful, a positive review on the store helps me a lot to get it noticed. Thank you!
