Delete your account
In the app: open Jellypaper Calm, go to Settings, then Delete account. This removes your account and synced artworks straight away.
Without the app: email hello@jellypaper.in from the address you signed up with, with the subject "Delete my Jellypaper account". We confirm and delete everything within 30 days.
Jellypaper Kids has no accounts, so there is nothing to delete. Removing the app removes the drawings on that device.
