Yes, we have Family Sharing enabled for both iOS and macOS. For information on how to set up Family Sharing, please read Apple's instructions here:
Unfortunately the Google Play Store does not currently support Family Sharing for in-app purchases. If they offer support for it in the future then we will be able to enable it.
The Windows version of Paprika is sold directly with a license key and does not support Family Sharing. Instead, you can use your license key on up to 3 devices.
