If you purchase Lookupper Pro from the Microsoft Store, you can use it on up to 10 PCs with the same Microsoft account, which is a great benefit.
There’s also an option to buy a key, but it’s available only to Russian users who use Russian-specific payment methods, as they cannot purchase Lookupper Pro from the Microsoft Store.
I’m considering implementing my own key licensing system for everyone. However, due to the restrictions in my country, I can’t use services like Stripe, so the Microsoft Store purchase flow is currently the best option available.
