Match access to the task
A camera app may need camera access and a navigation app may need location. That does not mean every request is necessary. Ask whether the permission supports a feature you actually intend to use, and decline optional access when it does not.
Prefer limited permissions
On supported Android versions, you can grant access only while using an app, select specific photos, or allow approximate rather than precise location. The available choices depend on your Android version and the app. Choose the narrowest access that lets the feature work.
Review special access carefully
Accessibility services, notification access, and device administration can give apps powerful capabilities. Do not grant them just because an installation guide says to. Verify the developer and the purpose first, especially for software obtained outside an official store.
Revisit permissions later
Find the app in Android settings and open its Permissions page; exact menu names vary by device. Remove permissions you no longer need and uninstall apps you do not use. A tidy permissions list is helpful, but it cannot by itself prove an app is safe.
