That depends. If you use the paid version, this version is not deleted by Google. If you want to switch on Fdroid. You need first to export your data (open the main menu -> three vertical dots -> export data). Then delete the app. Install the new one from fdroid and in the login page, click on three vertical dots, import data and select the previous file that was created. You will retrieve all your data.
@fedilab yeah paid version do i need to update it or no?
Strangely, this one was not affected by Google. So you don't need to move. Google Play releases come faster so you should already run 2.9.1
@fedilab i thought so thanks..
