The smartphone is the biggest data-leak problem that should be stopped as soon as possible. So if you have an Android device, you should solve this problem first. Server installation is recommended in combination with the smartphone so as not to lose the full functionality of many applications such as the cloud function.
Same as "Desktop" we provide just a "HowTo" for now.
The instructions for the smartphone can be found here (guideline.pwoss.xyz).
(To stop the leaking issues you’ll need an Android Phone. Microsoft and Apple aren’t modifiable for your privacy needs (closed source). Android is open source and it is perfectly usable without Google.)
