I used Anki for the last time like 4 years ago. Back then, all my decks were backed up on via AnkiWeb. They aren’t anymore, but I still have all the cards I’ve created on my computer.
Is there a way to upload them to AnkiWeb again? If there is, I can’t seem to find it.
I’m really scared of doing anything before asking bc I really don’t want to lose my cards.
AnkiWeb only deletes inactive user’s data for space, so unless there’s something else that’s an issue, syncing the data should just re-send it and then work as normal.
If you’re concerned about your cards, you can File, Export, then choose the whole Anki collection (including media). This makes a backup of every deck, card and all review history as explained here: Exporting - Anki Manual
