Don’t assume an app is safe just because it came from an official app store

Downloading apps from official sources such as the Apple App Store and Google Play is far safer than sideloading apps or buying them from third-party stores. Still, even official apps can have their security compromised or be problematic for privacy. The best way to mitigate your risk is to check the permissions the apps ask for (like microphone, camera, etc.) and to update them as soon as possible.
