License Key vs Google Play Family Sharing

I want to purchase an Android license key from but have a question about the the company’s policy.
On the Play Store, Cryptomator qualifies for Google’s “Family sharing”, this would enable my wife and I to use the product with one purchase. Will the license key being purchased direct from works the same way or will I need to purchase separate keys for my wife and I?
Thanks in advanced for the assistance.

Sorry for the late response.

You are allowed to use the license key on unlimited devices within your household.
