- android.permission.POST_NOTIFICATIONS
- android.permission.FOREGROUND_SERVICE
- android.permission.FOREGROUND_SERVICE_SPECIAL_USE
These are standard permissions required by Android to be able to run sshd as a service. It will allow the service to keep running, while you switch to other apps.
- android.permission.RECEIVE_BOOT_COMPLETED
Another standard permission which is needed to be able to start the service at device boot. You can enable/disable this in the app settings.
- android.permission.MANAGE_EXTERNAL_STORAGE
You will be requested to grant this permission. It is needed to be able to effectively use the "rsync" and "sftp" commands. Without it, you would only be able to access the app's embedded "files" directory.
As rsync is of course a means to make a private backup/sync of the files on your device, there is a need to give the app special permission to access all files.
This must be (and is) explicitly requested when the app is run, and involves you to open the device settings and manually give this permission. The app can only prompt you for this, and you must do this manually. You can of course deny/ignore this request if accessing the app embedded "files" directory is enough for your needs.
More info on MANAGE_EXTERNAL_STORAGE can be found in this Android doc article and in this Google article in the section "All Files Access Permission"
