1. Ads Tracking You Across Websites
Do you want advertisers to track you across other websites? Probably not. Advertisers are keen on doing this so that they can gather more data about you, including your location and preferences, and can therefore send targeted ads your way. Go to Settings > Privacy > Tracking. Here you’ll be able to see which websites are trying to track you. The best thing to do is to disable the feature altogether at the top so that no website has permission to ask if they can track your actions across other sites.
2. Personalized Ads
There is a setting within Privacy that is all kinds of suspicious. It’s called Personalized Ads and, according to Apple, turning off the setting will limit Apple’s ability to deliver relevant ads to you but will not reduce the number of ads you receive. But our experts say that is “not necessarily true. If there’s less information about you, you’re a less valuable advertising target.” And this makes perfect logical sense.
You might see fewer ads by disabling this setting because advertisers aren’t going to be willing to pay to show you ads.
Disable it by going to Settings > Privacy > Apple Advertising. Turn off this setting.
3. Microphone Permissions
How many of your apps have permission to access your microphone so that they can hear every word you say? Your answer is likely “none of them, thanks.” But unless you are actively making sure these apps can’t use your microphone, they could be doing so without your knowledge. Scary thought.
Head over to Settings > Privacy & Security > Microphone. You’ll see a list of apps that have requested access to your microphone. Toggle them all off or choose the ones that you’ll allow to have it for practical reasons — such as Zoom or Skype. The fewer apps that can listen into your conversations, the more privacy you’ll retain.
