We keep the account you create, your lesson progress, posts, comments, chat messages and subscription records. You can export your account data and the content you published, delete your posts, and ask us to delete your account. Payment records may be kept when the law requires it. Deleting an account ends access and unlinks public posts and messages. Content hosted by third parties, such as YouTube or Cifra Club, is not deleted by us. Email is the channel for account notices. Study reminders are optional.
