Check the permissions the app needs
The official app stores for Windows, macOS, Android and iOS are all now very good at listing the permissions an app needs before you install it. Apple’s platforms are particularly comprehensive, and will tell you plenty about the user data that the app is wanting to have access to as well.
You can check app permissions after installation too: Under Privacy & security in Windows Settings, under Privacy & Security in macOS System Settings, under Security and privacy, Privacy, and Permission manager in Android Settings, and under Privacy & Security in iOS Settings.
What you’re looking for here is anything that doesn’t look right: Permissions that overreach the remit of the app, in particular. If apps are asking for personal information, such as your location or your contacts list, make sure they’re giving good reasons for it.
