Your participation in group matches that already formed is anonymized, not deleted: your identifying link to the match is removed, but the match record itself (and the other members' view of it) stays, since it is shared group history, not solely yours.
If you own a group, ownership transfers automatically to another member of that group (whoever joined earliest); if you're the only member, the group is deleted along with you.
Your account and personal data are deleted immediately once you verify the emailed code below. Complete removal from backups can take up to 30 days.
No login required — verify by email instead.
