Open PooPal → Settings → Account & Cloud → Delete my account (tap twice to confirm). This immediately and permanently deletes:
your account (Google sign-in link),
your public profile (nickname, stats, gender setting),
all your synced poop entries,
your membership in all parties.
Data that stays: the local diary on your own phone (delete it by uninstalling the app), and anonymous world counters (e.g. "total poops logged worldwide"), which contain no personal data.
Email Poopal.Application@gmail.com from the Google account you used to sign in, with the subject "Delete my account" or "Delete my data". We will delete the same data listed above or your personal data within 30 days and confirm by reply.
