If you download the app from the App Store, notifications and widgets are free for 14 days from the first download date in Apple's signed app record. The app reads that record on your iPhone to determine access; it does not send it to a server run by us. If you use a TestFlight or local testing version, the app uses a separate trial start date stored on the device and shared locally between the app and its widgets. The app creates that date when it first initializes the testing trial. Deleting and reinstalling the app can affect locally stored testing records.App Store downloads include 14 free days of notifications and widgets from the first download date in Apple's signed app record.
