If you do find some compatibility issues, you can send feedback to the app's developer explaining the problem you encountered.

Question: Does Deleting An App Delete All The Data

The answer to this question all depends on the specific app. If the app stores the data to the server, data may still be saved. However, if the app does not do this then data stored on the device will be lost. Many apps, like Facebook, allow you to sign back into Facebook from a different device, keeping all your old posts and status updates. Other apps may delete all of your data when you delete the app.
