I love anki.

But upon reading this I think it's high time I exported all my notes in simple text format, just in case.

Maybe also try Fernando Borretti's flashcard app I saw (and dismissed) recently here

Anki uses a SQLite database for all its data, so it's already an open format.

Anki also regularly takes local backups.
