Felis

Felis is a free, ad-free Android link cleaner focused on privacy and fast sharing. It removes tracking parameters from links before you copy, share, or paste them.

Why Felis

• Clean noisy URLs in one tap
• Share privacy-friendlier links from anywhere
• Keep useful link analytics locally on-device
• Stay lightweight: no account, no cloud sync, no ads
