My account expired in 2020 and now I want to study for the entrance exam and I had all my notes in the anki, I need to use it again. How do I get them back?
I think that’s not possible. You can check if there is a local copy of it on your computer, though.
As AnkiWeb is a free service, we need to periodically delete unused account data in order to keep costs down. As mentioned in our terms of service, your data may be deleted if you have not accessed your account or synced in the last 6 months.
Once your deck data has expired, it is not possible for us to recover your data from AnkiWeb, but you may be able to recover it if you have a local copy.
