Yes. Every version of Paprika allows you to reinstall the version you originally purchased without having to purchase it again.
iOS
As long as you are logged into the App Store with the same Apple ID used to originally purchase the app, it will appear in the Purchases section of the App Store and allow you to reinstall it.
Mac
As long as you are logged into the Mac App Store with the same Apple ID used to originally purchase the app, it will appear in the Purchases section of the Mac App Store and allow you to reinstall it.
Android
As long as you are logged into the Play Store with the same Google account used to originally purchase the app, it will appear in the My apps & games section of the Play Store and allow you to reinstall it from there.
Windows
You can download the Windows installer from our website at any time and unlock the app using the license key you received when you originally purchased it. If you have lost your license key you can request it here.
Note
This only applies if you are trying to install on the same platform that you originally purchased on, and you are trying to reinstall the same major version. (For example: you purchased Paprika 3 for iOS and are trying to reinstall Paprika 3 on a new iOS device.)
It does not apply if you are trying to install on a different platform or different major version. (For example: you purchased the iOS version and are trying to install the Mac version. Or if you purchased Paprika 2 but are trying to install Paprika 3.)
