Léon - The URL Cleaner is an Android application which removes tracking and other obsolete parameters from a URL before sharing. Its usage is simple, integrating into Android's standard sharing mechanism.

Léon runs on Android 5.0 and later, is open source and does not contain any tracking or advertising frameworks. Léon does not collect any data about you.

The benefits of removing tracking parameters are:

Protects your and the recipient's privacy
Improves readability of links
Saves characters (in Tweets for example)
