A privacy-focused Android app written in Kotlin that transforms social media links to selfhostable alternative frontends before sharing them. First released under GPL v3 in 2025.

Vibe coded with Goose and Cline.

Transform any link to remove tracking parameters and convert social media links to privacy-focused alternatives:

• Remove tracking parameters from many URLs (UTM codes, social media IDs, analytics, etc.)
• 50+ tracking parameters automatically detected and removed
• Cloaked URL detection - extracts real URLs from redirect services
• Works on any URL - not limited to social media

• YouTube

  • Clean YouTube URLs (remove tracking parameters): youtube.com/watch?v=ID&si=tracking → youtube.com/watch?v=ID
  • Convert to Invidious instances for privacy: youtube.com/watch?v=ID → yewtu.be/watch?v=ID

• Twitter/X

  • Convert to Nitter instances: twitter.com/user/status/ID → nitter.net/user/status/ID

• Reddit

  • Convert to Redlib instances: reddit.com/r/subreddit/comments/postID → redlib.catsarch.com/r/subreddit/comments/postID

The app provides curated lists of alternative frontends that you can select from in the settings. Current defaults used when no custom instance is set:

• Invidious: redirect.invidious.io
• Nitter: twiiit.com
• Redlib: redlib.catsarch.com

• Seamless Integration - appears in Android share sheet
• Privacy First - works completely offline, no data collection
• Material Design 3 (Material Expressive) interface with light/dark themes
• Eink-friendly - high contrast for eink devices
