I am not sure if the current behavior is by design or a bug, but I just found out the hard way, that uninstalling the app does completely wipe all bookmarks forever.

IMO it would make more sense to store those into a location that persists and survives uninstalling / reinstalling like it is the case for many other applications which contain user data.

This is indeed a problem, without an easy solution for different reasons.
If you had backups enabled, then bookmarks should be stored there. It's a big question on how to properly extract them from a backup though (please share if you find a way to do it).
Storing bookmarks somewhere means that there are some servers, and there is some authentication mechanism for that. When you referred to "many other applications which contain user data", did you have in mind some apps without a login, like OM?
We plan to implement it somehow :) See #622

Sometimes Android asked you whether you also want to delete an apps data upon uninstalling. Perhaps there is a way to backup bookmarks to storage that persists reinstalling

I think "storing them somewhere" means on device Some apps store data on the device that survives being uninstalled Not sure if this only applies to older Android versions or newer ones as well. Haven't seen in it in a while Sometimes Android asked you whether you also want to delete an apps data upon uninstalling. Perhaps there is a way to backup bookmarks to storage that persists reinstalling

I am sadly not quite sure what you mean, is there a backup function in the app?

I know I can export / import bookmarks as .kmz files and that works pretty well, but this is a manual process and it does not store any settings (which sadly also get lost when uninstalling although not that big of a deal).

Yes I know multiple apps without login or any kind of server, they store the settings / user data under /storage/emulated/0/<appname>/settings or something similar. (Antenna Pod is one that comes to my mind.)

That folder stays there when the app is uninstalled.

I do not know if there is a way to tell the OS that specific files are user data and should not be removed.

OT: I actually think that storing the maps there would be beneficial too, since I would not need root access to be able move maps from one device to another (since they seem to be stored under /data/data/app.organicmaps/files/<date>/*.mwn which I can only access via root)

Unfortunately, starting from Android 11, these paths are not available anymore. https://developer.android.com/about/versions/11/privacy/storage

That is the main reason why we can't store data in publicly accessed folders.
