Syncing with an app sqlite3 db

Noob alert : I'm a beginner, sorry if my question is dumb

I would like to retrieve data from an sqlite3 db used and updated by a messaging app (on windows). I thought about using PHP to retrieve the info. However I cannot move the database on a server since it is used in the install folder of the app. How can I sync this sqlite3 database with a newly created sql database on a server? Or maybe (even better), is there a way to directly communicate locally with the app data base?
