How do I restore Unlimited Stamps?
Open 我的 → Stamp 权益 → 恢复购买. Purchases are restored through the App Store account that originally bought the non-consumable unlock.
What does the free version include?
The free version can keep up to 10 custom photo Stamps at the same time. Deleting a photo check-in also removes its Stamp and releases one free slot.
Why is a drink marked incomplete?
CaffOut does not invent caffeine values for unknown drinks. The record stays saved, and you can add or correct its caffeine amount later.
Do I need camera or location access?
No. Camera, photos, and location are optional enhancements. Basic drink logging works without them.
Does CaffOut upload my data?
No developer account or sync service is required. Read the privacy policy for the exact storage and Apple-service boundaries.
Still stuck?
Open a CaffOut support request. Describe what you expected, what happened, and your app version. Do not post sensitive personal data in a public issue.
