Can I share my 7Mind subscription through Family Sharing?

Unfortunately, no. The Family Sharing feature from Apple and Google only applies to the free content in the 7Mind app, but not to in-app purchases like subscriptions.

You can read more about what is and isn't included in Apple Family Sharing on this Apple help page. 7Mind is not a participating app.

You can read more about what content can be shared via the Google Play Family Library on this Google help page. In-app purchases cannot be shared with family members.

Of course, you can use your 7Mind subscription on multiple devices simultaneously, but only with the same profile.
