Not being able to use the benefits of my subscription

Please make sure you’re logged in to the Play Store app with the same Google Account that you used to purchase the subscription originally.

  1. Open the Google Play store app and select (top of the screen)
  2. Select the email with which you signed up for the first time.
  3. Install dfndr security

We recommend that you keep only the account used to purchase our subscription as the primary one on the Google Play Store app. It’s important to note that Google Play has conflicts to recognize signatures on some devices when the user is signed in to two or more accounts. This limitation occurs for all Play Store apps, not just with dfndr security.

Subscriptions (Ads Free, Pro and Ultra) are tied to the account you used to purchase.
This means that subscriptions cannot be transferred from an iOS device to an Android device (or the opposite) because they use different marketplaces (App Store for iOS devices and Google Play for Android).
