Sharing permissions
No one else can see your report unless you choose to share it.
A separate decision for each report. You decide which report to share. Sharing one report doesn't open up your other reports.
Inviting someone isn't sharing a report. Adding someone to My Universe doesn't mean you've shared your reports with them. Seeing the compatibility between you also needs both of your consent.
Your test answers stay private. In the compatibility report, you see results about your relationship. You can't see each other's test answers or the raw scores used in the calculation.
