Open Calomind → Settings → Account → Delete account → confirm. Your account is deleted right away.
Email [email protected] from the email address you registered with, subject “Delete account”. We'll handle it within 7 days.
Deleted: your account (email, password hash, Apple and Google sign-in links — Apple access is revoked), password reset codes, logged-day records, subscription records, friends, friend requests, block list, invite records (if someone invited you, only the link to you is removed), meals and photos shared with friends, meal photos in the cloud backup (subscribers), notifications and push tokens.
Kept without identity: usage statistics (anonymous) and the hashed device identifier (to prevent repeated free-quota claims on the same phone).
Your meal log and photos live on your phone; uninstalling the app removes them. The cloud backup (including subscribers' cloud photos) is deleted with your account.
Deleting your account does not cancel a subscription. Cancel it in your App Store / Google Play subscription settings.
