iPhone & Android
If you once bought Sleep Cycle as a one-time purchase, that purchase will only be valid on that platform.
A purchase can not be moved across platforms, so if you bought Sleep Cycle on your iPhone, you will not be able to restore that purchase on an Android phone.
iPhone
To restore your purchase on your iOS device with the same Apple ID as you purchased Sleep Cycle with.
Go to: Statistics - Scroll down on the paywall - press "I have already paid for Sleep Cycle" - press Cannot access account - Restore Purchase.
Android
To restore a purchase from an Android device to another send us a print screen of your old Sleep Cycle receipt and we will help you to restore your early adopter premium.
If you don't have the receipt in your email, you will find it via https://payments.google.com/
Make sure that you can see the GPA-number on the receipt.
