How do I cancel my subscription?

Subscriptions are managed by Apple. Go to iPhone Settings → Apple ID → Subscriptions, select Calo Premium, and cancel. Cancel at least 24 hours before the current period ends, or it renews automatically.

How do I restore my subscription on a new phone or after reinstalling?

Sign in to the App Store with the Apple ID you purchased with, open Calo8, go to Me → Calo Premium, and tap Restore purchases.

How do I delete my account?

On the Me tab, tap Delete Account. This deletes the account’s meal records, targets, subscription records, and other data from the server. Deleting your account does not cancel a subscription; cancel it separately as described above.

What if the recognition result is wrong?

A photo scan produces an editable draft. Before saving, you can change food names and portions, or add and remove foods. Recognition results and nutrition values are estimates.
