jp343 Track Your Japanese Immersion geliştiren: jp343

jp343 tracks your Japanese immersion time on YouTube, Netflix, Crunchyroll, and any other site (via manual tracking). Built for Japanese learners, but works for any language.

The extension detects video playback and records sessions automatically. YouTube ads are excluded from your watch time. If your browser crashes, the session is recovered on restart.

Built-in dashboard with activity heatmap, weekly stats, streak tracking, and full session history. All inside the extension.

You can block YouTube channels from being tracked and edit session titles. No account needed. Everything works locally.

Optional: Create a free account to sync across devices and keep your data safe.

How to use:
1. Play something on a supported site
2. The tracker starts on its own
3. Check your stats in the popup or open the full dashboard
