Your entire life is contained in that glass slab in your hand. From emails and private messages to photos and videos of your most treasured moments, it’s all there. However, you probably don’t spend anywhere near enough time making sure your phone is configured to protect your secrets. This applies whether you’ve had your phone for years or just got a new one in the Black Friday sales.
There are a couple of different ways to think about privacy when it comes to your phone. There’s the data that it collects about your actions and interests, and then there are the protections you can put in place to stop people around you from accessing the physical device. Both are important, and there are easy things you can do to improve each of them.
Before we get into what you can do to improve your phone, there’s the sticky issue of Google. The tech giant owns and develops the Android operating system, and it is also one of the biggest collectors of personal data there is. The firm’s business model is based on making money by getting people to click on ads, and the information you provide it with goes towards this end.
So if you’re looking for more privacy in the everyday actions you take on your phone, you may wish to consider moving to iOS. However, that doesn’t mean there aren’t ways to improve some areas of your phone’s privacy.
Get the Basics Right
Getting the fundamentals right is the first place you should start. These are the things that people in the security and privacy world have been advocating for years, and, most likely, they’re the things you already know and (we hope) already do. The first line of defense to stop someone getting into your phone is a screen lock—a PIN or passcode is better than a pattern swipe.
Beyond that you should be using a password manager to create unique login details for all your online accounts and making sure two-factor authentication is turned on for as many of these accounts as possible. Both will limit how easy it is for someone to hack into your account using details that were previously swept up in data breaches.
Automatic software updates should be turned on to plug any potential bugs or security flaws in the code that your device runs. For apps this is done in the Play Store settings, under the auto-update apps option. For the wider Android OS, you need to visit the Settings app and find “system updates” (depending on the make of phone you have, it can be in different folders). While we’re talking about apps, you should also visit the privacy menu in the Android settings and check which permissions you have given each app. It’s likely that you’ll be able to turn off location sharing and access to photos and files for a lot of apps. Now that all those bits are out the way, let’s move on to some of the meatier stuff.
Lock Your Apps
You have a password or PIN on your phone to stop people from getting into it if it falls into the wrong hands. But sometimes that isn’t enough. There are times when you will want to hand your unlocked phone to the people around you—showing photos to friends, for instance, or giving it to your kids to play on—and you may want to consider putting some extra locks on the apps you want to be more secure. Unlike Apple’s iOS, Google allows apps to request permission to control other apps. This means password-locking individual apps is possible.
To lock your apps, you’re going to need another app. There are plenty available on the Android app store, and, as with all downloads, you should be cautious of what you’re accessing. If an app is full of ads, doesn’t have clear privacy policies, or isn’t from a trusted developer, then you should probably avoid it. For an app locker, Norton App Lock is a good place to start. It’s from a trusted security name, and it allows individual apps or groups to be covered by the same passcode.
Hide Leaky Notifications
Travel isn’t really an option for lots of people right now, but there’s nothing more mortifying than someone peering over your shoulder on public transport and seeing notifications pop up with the full message contained. It’s a feeling that’s also repeated when you’re sharing your screen with colleagues and a gossip-filled message about the meeting you’re in flashes up.
