Purchases are processed by Apple. dvivb uses RevenueCat to verify your entitlement (for example Lifetime access). Manage or request refunds according to Apple's policies from your Apple ID settings.
In the app, use Restore Purchase where shown, and ensure you are signed in with the same Apple ID used to buy. If it still fails, email us with a short description.
Checklists, logs, and photos you save through the app are stored on your device. Back up your device if you want to preserve that data. We do not host your log content on our servers.
Reminder scheduling may be available for eligible purchases. Allow notifications in iOS Settings if you want alerts. You can change this anytime in Settings.
No. dvivb is a logging and checklist tool. It does not diagnose or treat any condition. If you need clinical support, contact a qualified professional.
See our Privacy Policy for how purchase and on-device data are handled.
