The first time you sign in to Call Control, you will be prompted to give the app access to your contacts. If you accept, this will automatically add your contacts to the allowed list.

Note: Call Control does not share or store your contact information outside your phone. In addition, you can add a number to the allowed list manually. To do so, Click the “Call Filter” icon at the left hand corner of the gray bar at the bottom of the screen within Call Control app. Tap “Allowed List”. Next, tap the small plus sign at the top right hand corner of the screen. Type a number manually in the “Number” field, or tap “Pick from Contacts” icon next to the Name field to add a number that is already in your phone’s contact list. Tap the button “Add”.
