If you have previously purchased our software via the Google Play Store and would like to install it on to other devices that you own, you can do this by simply adding the Google account that you used to make the initial purchase on to your new device(s). You can then install as usual via the Play Store without needing to re-purchase it.
Your licence/purchase information is tied to the Google account that was used to make the original purchase, therefore all you need to do is add this account to your new device. You can do this by following the steps below:
Open the Play Store and touch the profile icon on the top right.
Tap the down arrow next to the existing account name and pick 'Add another account'.
Follow the sign in instructions and enter your original (purchasing) account details.
Load the Play Store and, if necessary, select your added account (touch the profile icon on the top right to view the accounts).
You should now be able to install the app through the Play Store as usual without needing to re-purchase it.
Our apps are also eligible for Google Play's family library feature. To sign up for family library, please refer to Google's guidance at https://support.google.com/googleplay/answer/7007852?hl=en
