Pro is included automatically โ€” there is nothing to buy again. Tap Restore Purchases in Settings if it doesn't appear. Privacy: the 4DAT method Your scans stay on your device. RF 4DAT does not collect, sell, or share your data, and there is no analytics or tracking. Location, when you allow it, is used on-device only to label a scan with a place name; coordinates are never stored. Please use RF 4DAT only where you have permission and legal authority. It is not for stalking, covert surveillance, or identifying people. Device counts are estimates of nearby signals, not identifications of individuals.
