Permissions in Android apps can be a mess. Do you ever see prompts like these when you want to install something? For many free apps and services, the user is the product. Do you want to give away your personal information, friends’ numbers, exact location, photos, and texts to whoever made that app? If not, you couldn’t use that app at all. AppVeil can help.
