I want to store user data (like ToDo lists with items) in his own google cloud (cloud datastore, cloud sql, firebase, …) or google drive. Is it possible, is it a good or bad idea? And what might be the best storage option for this case?
Looks like the best option is to use google account to login into app, and then store data using ‘Google Drive API’?
Why don’t you just let the user log in with his Google account and then store the data as normal in your Firebase project for the app?
I just did not want to store all the data in one central database, and thought users might be more relaxed knowing that data(maybe something sensitive) is stored in their own storage.
That might work. There is a another user working on something like that right now, by seraching for “Google Drive” here in the forum you will probably find his post.
