  **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).
