Saving Setting Option (Local or Database)


I am adding various intro pop up screens / messages to my app that explain various parts of the app... such as:



This section allows you to... etc.

[ ] don't show this again


User's can click the 'don't show this again' option and the setting will be saved,so that they don't see the message again, however i am trying to decide where to save this setting.

Which do you think is a better method?

A - save the setting to locally within the app (quicker access, but would future updates cause problems)

B - save the setting to the user's profile in the database (slower, but would not effect future updates)

Any advice on this would be greatly appreciated, thank you.
