OpenKeychain helps you communicate more privately and securely. It uses high-quality modern encryption to ensure that your messages can be read only by the people you send them to, others can send you messages that only you can read, and these messages can be digitally signed so the people getting them are sure who sent them. OpenKeychain is based on the well established OpenPGP standard making encryption compatible across your devices and operating systems.

Modern encryption is based on digital “keys”. OpenKeychain stores and manages your keys, and those of the people you communicate with, on your Android. It also helps you find others’ keys online, and interchange keys by touching devices. But its most frequent use is in using those keys to encrypt and decrypt messages.

### DISCLAIMERS :
Adding custom repo might not be as secure as the official one so I&#39;m not responsable if you encounter any problems with them ! I encourage you to do your own research about it !

Also while open source is great for privacy and security it is not perfect. So keep that in mind before downloading any apps.
Most apps that I&#39;ve listed are privacy friendly but some might be not be perfectly private and secure. I again encourage you to do your own research about them.

I am not a privacy and security expert. I&#39;m also don&#39;t consider myself as a developper so I do not have any technical knowledge and so I didn&#39;t look into any source code of any apps in this list !

English is not my mother tongue ^^&#39;

Bear in mind that I haven&#39;t found replacements for all of the privative, closed source software I previously used, so you may see some of it untill I find a proper replacement and remove it.
