As they say, Big Data is Big Money, and it’s hard to get around online these days. There are even toggles in the operating system themselves that let you disable location services but will continue storing your location data on their servers. Thankfully, Android is open source and many have gone for the pure AOSP flavor without letting any of Google’s code touch their device. That’s why it was interesting when XDA Recognized Developer M66B released an email application called FairEmail with the goal of being privacy-friendly.

FairEmail is open source, available on GitHub, and even has a testing program available in the Play Store (as of the writing of this article, the program is not live). Some would assume this means the application is light on features, but FairEmail is feature packed. Check out the full list of features below.
