Shufflick, by Benjamin Leach
Email contact@benleach.com from the email address on your account, with the subject "Delete my Shufflick account". Include your username if you know it. We'll delete it within 7 days and reply to confirm.
Everything: your account, email address, username, profile photo, favorite film, lists, ratings, reviews, watch history, goals, roll history, follows, Blends, blocks, notification settings and import records. You are also taken off any lists shared with you. Nothing is kept, and it can't be undone.
Reports you made about other users are kept so they can still be reviewed, with nothing that identifies you. Server logs are kept for a short time and then deleted.
More detail is in the privacy policy.
