Why don’t I see any contacts?
- Allow WhoKnows to access your contacts (your phone’s settings → WhoKnows → Contacts).
- Your contacts need to be on WhoKnows themselves. Invite them under Profile → Phone book.

Sign in with your account and tap “Restore purchases” under Profile → WhoKnows Pro. This works with the same Apple ID or Google account you used to buy it.
