Apple handles App Store billing and cancellation. Glucose can restore access when the same Apple ID owns an active purchase.
Check the current offer in Glucose
Open the purchase screen to see the current feature list, price, billing period, and any available trial. Offers and included features can change.
Restore an existing purchase
Confirm the iPhone is signed in with the Apple ID used for the original purchase. In Glucose Settings, choose Restore Purchase.
Manage or cancel through Apple
On the iPhone, open Settings, tap your name, then Subscriptions. Choose Glucose to view, change, or cancel the subscription.
Get help when access is missing
Confirm the subscription is active under the same Apple ID. If Restore Purchase still cannot find it, contact support and include the Glucose version and a description of what the purchase screen shows. Do not send payment credentials.
