MyTube от FAIGO

MyTube organizes your YouTube library locally inside the browser. It builds
a dashboard for subscriptions, latest uploads, liked videos, history, and
playlists without using a separate cloud service or account.

Key features

• Unified dashboard for subscriptions, latest uploads, liked videos,
  history, and playlists
• Local playlists and queue control
• Local search with optional remote YouTube suggestions
• Import/export as JSON for backup or migration
• Audio‑only mode and low‑quality toggles for bandwidth‑friendly viewing
• Theme and language controls

Privacy
MyTube stores its own data in extension storage and IndexedDB. Content
scripts read page metadata to build your local library. Your MyTube library
stays on your device unless you export it. YouTube still receives normal
viewing/network data when you browse the site.
