When Apple announced the iPhone 4S, few changes made more waves than Siri. Siri is a virtual assistant that utilizes Wolfram Alpha and Wikipedia to answer just about any question the user has. It also enables you to schedule reminders, make appointments, set timers, control musical playback, place phone calls, and more without needing anything more than your simple voice commands as its guide. Unfortunately, it also allows users to interact with your phone while it’s locked by default. Don’t worry though, you can customize Siri’s security and location tracking settings fairly easily. Here are a few tips on how to customize Siri security settings.

Turn Off Siri When the Phone is Locked
Keeping Siri from falling into the wrong hands is a relatively simple process. You want to make it easy for you to access your virtual assistant, but you don’t want your friends setting alarms and appointments on your behalf. Here are the steps you can take to make this happen:

  • Launch Settings.
  • Select Passcode Lock near the top of the General menu.
  • Look for and toggle Siri’s switch to the Off position.

Now, you shouldn’t be able to access Siri without first unlocking your phone. Make sure your phone has a passcode that’s easy for you to remember and quickly access though, as you are sacrificing convenience for security.

How to Customize Siri Security SettingsCustomize Location Tracking Options
Siri has a tendency to track your location whether you realize it or not. This can be both a huge battery drain, and a security concern for those of you who aren’t fond of being tracked everywhere you go. To toggle these controls, follow these steps:

  • Launch Settings.
  • Select Location Services.
  • Turn Off any services or programs you don’t want tracking you.
  • Scroll down to the bottom of the menu.
  • Select System Services.
  • Do the same here.

At the bottom of this menu, you’ll see an option to give you a Status Bar Icon indicating that a system service is tracking your location. I recommend toggling this on. This will make you aware of any tracking being done by a system service as opposed to a third-party app. This can help you identify battery draining services that may be running.

If you want to kill all location tracking on the phone, simply toggle the top Location Services option in the main Location Services menu accessible through Settings. This may cause problems with one or more of your third-party apps, and restrict your ability to use services such as Maps and Find My iPhone.

With these tips in mind, you should have a much better grasp on how Siri works, and how these various services use location tracking on your phone.
