고고케이스 is a lifestyle shopping app that specializes in smartphone cases. The app offers a wide range of cases, including artistic graphic cases, unique and hard-to-find designs, affordable film cases with layered films, and custom cases using self-designed files.

Upon installing the app, users are provided with exclusive app coupons, making it a must-have for smartphone case enthusiasts.

The app requires certain permissions as outlined by the "Act on Promotion of Information and Communications Network Utilization and Information Protection." The required permissions include access to phone identification for initial setup and access to storage for file uploads, button representation, and push images. Optional permissions include location access for push notifications related to nearby stores.

To revoke permissions, users can go to Settings > Apps or Applications > Select the app > Select permissions > Agree or revoke access.

Please note that for devices running Android 6.0 or below, additional permissions for device ID and call information, as well as device and app history, may be required. Additionally, location access may be included for push notifications related to nearby stores.

Upgrade to Android 6.0 or higher is recommended for individual consent to permissions. However, even after upgrading the operating system, previously granted permissions will not change, so users will need to uninstall and reinstall the app to reset permissions.

Overall, 고고케이스 is a convenient shopping app for smartphone cases, offering a variety of unique designs and exclusive app coupons.
