Audit Your App Permissions
Many apps request access to your location, microphone, camera, and contacts, even when they don't need it. This is a primary way your data is collected. Take a few minutes to conduct a permission audit. For apps that don't require constant access, such
as social media or shopping apps, change their location permission to 'Allow only while using the app' or 'Don't allow'. On an iPhone, you can find this under 'Settings' > 'Privacy & Security'. On Android, navigate to 'Settings' > 'Privacy' > 'Permission Manager' to see which apps have access to sensitive data. Revoke permissions for any app that seems overly intrusive.
Reset Your Advertising ID
Both Android and iOS assign your device a unique advertising ID. This code allows advertisers to build a detailed profile of your habits by tracking your activity across different apps. You can effectively sever this link. On an Android device, go to 'Settings' > 'Privacy' > 'Ads' and select 'Delete advertising ID'. For iPhone users, the path is 'Settings' > 'Privacy & Security' > 'Tracking', where you should turn off 'Allow Apps to Request to Track'. This single step significantly reduces cross-app profiling.
Keep Your Software Updated
One of the simplest yet most critical hygiene habits is to keep your phone's operating system and all your apps updated. Software updates frequently contain patches for security vulnerabilities that malicious tracking software, or 'spyware', can exploit to get onto your device. By ignoring updates, you are leaving known security holes open for attackers. Enable automatic updates on both iOS and Android to ensure you are always protected by the latest security fixes without having to think about it.
Secure Your Lock Screen
Your lock screen is the first line of defense. Using a simple four-digit passcode is no longer sufficient. Opt for a stronger six-digit or alphanumeric passcode to make it much harder for anyone to gain physical access to your device. Furthermore, notifications on your lock screen can reveal sensitive information from messages or emails to anyone who glances at your phone. You can disable lock screen previews for specific apps or for all notifications in your phone's settings, ensuring your private communications stay private until you unlock your phone.
Be Wary of Public Wi-Fi
Free public Wi-Fi networks in cafes, airports, and hotels are notoriously insecure. Cybercriminals can position themselves on these networks to monitor your activity or trick you into connecting to a malicious hotspot. Avoid accessing sensitive information like banking apps or making purchases while on public Wi-Fi. When you must use a public network, consider using a reputable Virtual Private Network (VPN) service. A VPN encrypts your internet traffic, making it unreadable to anyone trying to eavesdrop. Also, make it a habit to turn off your Wi-Fi and Bluetooth when you aren't actively using them to prevent your device from being tracked via network scanning.
Scan for Hidden Spyware
Spyware, sometimes called 'stalkerware', is malicious software designed to secretly monitor your activity, record calls, and track your location. These apps often disguise themselves as system utilities to avoid detection. Signs of spyware can include a suddenly draining battery, unexplained high data usage, or your phone overheating. On Android, running a Google Play Protect scan can help identify malicious apps. For iPhones, which are less susceptible but not immune, check 'Settings' > 'General' > 'VPN & Device Management' for any configuration profiles you don't recognize and remove them. Regularly deleting apps you no longer use also reduces your risk.
