Review app permissions
Open the privacy or permissions section of your phone and review access by category. Camera, microphone, location, contacts, photos, nearby devices, and notifications are the most important. Remove permissions that no longer match how you use the app.
For photos, choose limited access where available. A delivery app usually does not need your entire photo library. A note app may not need contacts. A game rarely needs microphone access.
Use precise location only when needed
Many apps ask for precise location because it is useful for ads, analytics, or convenience. Weather, transit, rideshare, and maps may need precise location while in use. News, shopping, and casual apps often work with approximate location or no location at all.
Set location access to "while using" instead of "always" unless the app clearly needs background access, such as trusted navigation, safety, or device-finding services.
Clean up notifications
Notifications can expose private details on the lock screen and train you to open apps more often. Turn off notifications for apps that mostly send promotions. For messaging and email, consider hiding message previews on the lock screen.
Notification privacy is not only about secrecy. It also reduces distraction and makes suspicious alerts easier to notice.
Reset advertising identifiers
Phones may include advertising IDs used to measure and personalize ads across apps. Review ad personalization settings and reset or limit the advertising identifier if your operating system offers that option. This does not remove all tracking, but it can reduce one common link across apps.
Check cloud backups
Cloud backups are convenient and can save you after a lost phone, but they may include photos, app data, messages, and settings. Review what is backed up and whether sensitive apps use separate encryption or their own backup systems. Make sure your cloud account has a strong password and multi-factor authentication.
Remove unused apps
Old apps may keep permissions, background access, and account tokens. Delete apps you no longer use. If you might need an app once a year, it is usually safer to reinstall it when needed than to leave it installed permanently.
Set a stronger lock screen
Use a strong passcode, not a short pattern that can be guessed from smudges or shoulder surfing. Biometrics are convenient, but the passcode is still important because it often protects device encryption and account changes.
