How to share my purchase with my family?
Genius Scan doesn't offer Family Plans for subscriptions. If this is something you're interested in, please let us know.
However, if you purchased Genius Scan+ at a one-time fee, you should be able to share it with Family Sharing.
Unfortunately, due to Google Play restrictions, sharing Genius Scan subscriptions with your family library is impossible.
You can cancel or request a refund for your subscription as described here: Get a refund on Google Play. You can then purchase Genius Scan Enterprise directly on Google Play, which you can add to your Family Library.
