SizeHunt, made by Plainwork Apps.
In the app: open My sizes, scroll to Your account, and tap Delete my account. It happens right away.
Or email [email protected] from the address you use in SizeHunt, with the subject "Delete my SizeHunt account".
We delete your email address, sizes, watches and everything found for them within 30 days, and reply to confirm.
To stop alert emails without deleting anything, use the link at the bottom of any alert.
