SiteBlocker — Focus & Website Blocker

About

SiteBlocker is a premium, privacy-first website blocker designed to help you eliminate digital distractions, reclaim your attention span, and build deep focus habits.

Built on the modern, high-performance Manifest V3 network architecture, SiteBlocker blocks distracting sites at the browser level with zero performance overhead, zero lag, and absolute data privacy.

🔥 KEY FEATURES

1. DYNAMIC WEBSITE BLOCKING
Block any distracting website (and all its subdomains/routes) instantly with a single click. Our dual-layer blocking engine intercepts requests at both the network stack and client-side page load, ensuring service-worker cached pages and Progressive Web Apps (like YouTube, Google Docs, or social media networks) cannot bypass your lock.

2. STRICTOR FOCUS MODE (PRO)
Need iron-clad discipline? Active Strict Mode to lock your blocklist and settings. The blocker cannot be bypassed, and settings are locked behind a secure 4-digit PIN verification.

3. MINDFUL MODE (PRO)
Introduce deliberate friction. Instead of a hard wall, Mindful Mode triggers an 8-second breathing pause, prompting you to breathe and reflect before choosing whether to proceed to a blocked site. 

4. POMODORO FOCUS SESSIONS (PRO)
Start timed focus sprints (25, 45, or 60 minutes). During an active session, a real-time countdown timer is displayed on all blocked screens, and access to distracting sites is completely restricted until the timer expires.

5. AUTOMATED SCHEDULES
Set repeating schedules (e.g., Mon-Fri, 9:00 AM - 5:00 PM) to automate your blocking rules. SiteBlocker handles the rest, allowing you to focus during work hours and relax afterwards.

6. SECURE ANTI-TAMPER ENGINE
SiteBlocker includes a background security engine. If a user attempts to alter settings or disable blocks via local browser DevTools, the extension automatically detects the write attempt, overrides it, and restores your secure states.

🛡️ PRIVACY & PERFORMANCE
- Zero Tracking: We do not log, track, or collect your browsing history. Everything is computed and stored locally on your device.
- Battery-Friendly: Powered by Chrome's native declarativeNetRequest engine, running at the browser level with near-zero CPU and memory usage.
