+* [I2P-Bote](https://i2pbote.xyz/) - I2P-Bote is a plugin for I2P that allows users to send and receive emails while preserving privacy. It does not need a mail server because emails are stored in a distributed hash table. They are automatically encrypted and digitally signed, which ensures no one but the intended recipient can read the email, and third parties cannot forge them.
+* [I2P-Bote Android](https://play.google.com/store/apps/details?id=i2p.bote.android) - Android release of I2P-Bote. (Google Play)
 
+## Tools
