YouTube Time Limiter

Limit viewing time for specific YouTube content

**Three Operating Modes** - **Timer Mode** — Pure time management, no content filtering. - *Daily sub-mode:* a global time quota. Once exhausted, immediate redirection. - *Session sub-mode:* work/rest cycles. Configure number of sessions, duration and break time. YouTube is blocked during breaks and after the last session. - **Keywords Mode** — Content-based filtering using video titles and descriptions. - *Global sub-mode:* a single shared timer for all keywords. - *Individual sub-mode:* a dedicated timer per keyword, with progress bar and remaining time on hover. - **Mix Mode** — Combines a daily timer (absolute ceiling) with individual keyword timers. Without a detected keyword, only the daily timer counts down. With a keyword, both timers count down in parallel. **Time Management** - Time only counts while a video is actively playing. Paused video = paused timer. - Anti multi-tab stacking: 1 real second = 1 counted second, regardless of how many videos are open. - Configurable reset time (midnight by default), applied to all modes. - Real-time counter always visible, adapted to the active mode. - Supports regular videos, Shorts and minimized player. - Configurable redirect URL in administration settings. **Keyword Import / Export** - Export keyword lists to JSON (global and individual keywords with their timers). - Import from JSON with smart merge that preserves already consumed time. - Available in Keywords and Mix modes. **Security and Parental Control** - Password protection for all settings. - Modify or remove password (leave field empty to disable). - ON/OFF button also password protected. - 100% local data — nothing is sent to external servers. **User Interface** - Clean, modern and compact design with collapsible sections. - Dynamic remaining time display adapted to the active mode. - Individual keywords are collapsible: name visible, details on click. - Multilingual: *EN*, *FR*, *DE*, *IT*, *ES*, *JA*, *PL*. - Automatic browser language adaptation. - Help link to [full documentation](https://www.acem-tech.uk/en).
