When you sign up, Omnimemory collects your username, email, and password for the purpose of providing the service.
Public flashcards, i.e. those that you don't mark as private, can be stored and used by others. Copies of these flashcards may remain even after you delete them, make them private, or delete your account. In fact, if other users have these flashcards marked for learning, Omnimemory will automatically make private copies for them so that they can continue learning them.
Unless stated, prices do not include any EU VAT that may have to be added. The VAT rate depends on your country.
If you pay for the premium service, at the end of the paid period you'll have the option to renew (renewal is not automatic).
