To download a GitHub release you might need to expand the assets section to download the [APK file](https://en.wikipedia.org/wiki/Android_application_package).

The GitHub version is being updated more often than the Play store version.
The GitHub release will automatically check for updates on GitHub.
You can turn this off in the miscellaneous settings.

Certificate fingerprints:

```
MD5: 64:90:8E:2C:0D:25:29:B0:D0:26:2D:24:D8:BB:66:56
SHA1: 17:BA:15:C1:AF:55:D9:25:F9:8B:99:CE:A4:37:5D:4C:DF:4C:17:4B
SHA256: E0:20:67:24:9F:5A:35:0E:0E:C7:03:FE:9D:F4:DD:68:2E:02:91:A0:9F:0C:2E:04:10:50:BB:E7:C0:64:F5:C9

One line command to display certificate fingerprints:

I do not hand over the signing keys of my apps to Google.

* [F-Droid](https://f-droid.org/en/packages/eu.faircode.email/) ([last build status](https://f-droid.org/wiki/page/eu.faircode.email/lastbuild))

Note that F-Droid builds new versions irregularly and you'll need the F-Droid client to get update notifications.
To get updates in a timely fashion you are advised to use the GitHub release.

Because F-Droid builds and GitHub releases are signed differently, an F-Droid build needs to be uninstalled first to be able to update to a GitHub release.

## Privacy

Please see [here](https://github.com/M66B/FairEmail/blob/master/PRIVACY.md#fairemail) for the privacy policy.

## Compatibility

FairEmail requires at least Android 5 Lollipop.
Individual message notifications are available on Android 7 Nougat and later only
because earlier Android versions do not support notification grouping.

FairEmail will work properly on devices without any Google service installed.

See [here](https://github.com/M66B/FairEmail/blob/master/FAQ.md#user-content-known-problems) for known problems.

## Support
