DeepFocus: Site Blocker is a privacy-first, schedule-based website blocker designed for knowledge workers, students, and anyone who wants to reclaim their focus time. How It Works

Create Rules: Define which sites to block (e.g., youtube.com, twitter.com, instagram.com)
Set Schedules: Choose specific time ranges (e.g., 09:00–12:00 Mon–Fri) or daily time budgets (e.g., 30 minutes/day)
Stay Focused: When a rule is active, blocked sites redirect to a friendly reminder page with a countdown
Global Toggle: Turn all protection on/off with one click from the popup dashboard

Key Features

Two Blocking Modes:
Time Range: Block sites during specific hours and days
Daily Budget: Allow limited time per day (e.g., 30 min for Twitter) — once exhausted, the site is blocked until midnight
Midnight Countdown: For budget-exceeded rules, the blocked page shows a live countdown to reset
Dark Mode & Light Mode: Choose Light, Dark, or follow your system theme
Bilingual UI: Full Turkish (Türkçe) and English support
100% Local: All data stays on your device — no accounts, no cloud, no tracking
No Ads, No Premium: Completely free with no paywalls
