No. Teams, players, matches, and events are stored only on the device where you enter them. There's no account and no server, so nothing syncs between an iPhone and iPad, for example.
Please email a short description of what you were doing, what you expected, and what happened instead. A screenshot helps a lot if it's a display issue.
