> The thing that makes hashcards unique: it doesn’t use a database. […] Your performance and review history is stored in an SQLite database in the same directory as the cards.
Man I was really looking forward to seeing how they stored review history in plain text.
Absolutely the same here. It seems weird to have 'no database' as the selling option for the main system, but then use SQLite for that slice of it.
The OP says that he doesn't want _cards_ be stored in opaque format, because they are valuable. The review history he doesn't care about.
But, yeah, phrasing could've been a bit more precise.
