When you first install the 2ndLine App, you might get a message asking if it can access your contacts. This allows the app to sync with the contacts saved on your phone. It's meant to make things easier for you, so you can quickly find and contact people you already know. But don't worry, giving access to your contacts is totally up to you. You can still use the 2ndLine App even if you decide not to let it see your contacts.

If you want to control which contacts show up in the 2ndLine App, here's what you can do:

  1. Open the 'Settings' app on your iPhone.
  2. Look for "2ndLine" in the list of apps and tap on it.
  3. You'll see an option called "Contacts". You can turn this ON or OFF to decide whether you want the app to access your phone's contacts or not.
