What will happen to my hosted vault if I ever decide to cancel a premium subscription?
Will I just lose features?
Can I still export all my data?
Will I lose access to data (until I re-subscribe)?
Will any data be deleted?
I haven’t tried it yet, but so far, the latest services I’ve been dealing with that have premium subscriptions just limit the “beyond” access you’d normally have. You’ll have limits for certain things, but entries that are already there, won’t be inaccessible. (Uploaded attachments, saved 2FA tokens, won’t be lost. Additional 2FA methods, password hygiene reports won’t work anymore as a free user.)
