You can definitely enjoy the benefits of your dfndr subscriptions in multiple devices, as long as the same Google account  used to purchase our subscription in the first device is the same one registered on your other devices.

To activate your subscription in another phone, just keep as the main account on the Google Play Store  app the same email used to buy our subscription initially.

Important: Subscriptions cannot be transferred from an iOS phone to an Android device (or vice versa), as they use different payment platforms (App Store for iOS devices and Google Play for Android) and the features available in each of these versions is also different, due to Apple Store and Google Play policies.
