**NOTE:** If you have any troubles, check [this extensive FAQ](https://github.com/M66B/FairEmail/blob/master/FAQ.md).
You may also ask in [this XDA Forum thread](https://forum.xda-developers.com/t/app-5-0-fairemail-fully-featured-open-source-privacy-oriented-email-app.3824168/)
or via email to [marcel@faircode.eu](mailto:marcel@faircode.eu). Bad reviews won't help you or the developer, so try asking in person first.
## 1. Accepting the License Agreement
When you start the app for the first time, you need to accept the license agreement.
If your email provider is not listed, or if you want to authenticate using a password, choose "Other provider".
**NOTE:** OAuth only works for the Play Store and GitHub version. Third party builds (e.g. on F-Droid) do not support OAuth.
**NOTE:** Google OAuth only works for Google accounts added on your Android device. Also see [FAQ #111 Is OAuth supported?](https://github.com/M66B/FairEmail/blob/master/FAQ.md#user-content-faq111)
**NOTE:** Even with battery optimization disabled, FairEmail won't drain your battery. The app usage will be high. But that does not mean high battery usage. See [FAQ #39 How can I reduce the battery usage of FairEmail?](https://github.com/M66B/FairEmail/blob/master/docs/FAQ-en-rGB.md#user-content-faq39) for more information.
### 1. Disable the permanent notification (watchdog)
The watchdog is a necessary foreground service as many phones kill the app once there is nothing in the foreground anymore.
However, it is designed in a way that it has no toll on your battery. If the permanent notification banner annoys you you can just turn the notification off.
To do so, press and hold on the notification and then click on the settings icon (gear symbol).
