App permissions are settings that allow mobile applications to access specific features or data on your device. For example, an app may request permission to use your camera, location, or contacts. These permissions help the app function properly but can also raise privacy concerns if not managed carefully. When you install an app, you typically see a list of permissions it requires. You can choose to accept or deny these requests. It's important to review these permissions to ensure that the app only accesses the information necessary for its intended purpose, protecting your personal data from unnecessary exposure.
