갤러리아 is a lifestyle app developed by Hanwha that offers a wide range of features for convenient shopping. With this app, users can make app card payments, access shopping information for their preferred stores, and even receive personalized coupons. It also allows users to take advantage of special promotions, convert mileage points, and exchange paper gift certificates for the app's mobile cash, known as G-cash, which can be used just like real money.

When shopping at 갤러리아 department stores, the 갤러리아 app is a must-have. It introduces several new features including app cards, G-cash, coupons, parking tickets, e-DM, MOSAIC, and more. The app requires certain permissions to ensure smooth functionality, such as access to storage for seamless usage.

In accordance with the Information and Communication Network Act, starting from March 23, 2017, 갤러리아 only requests essential permissions necessary for its operation. Optional permissions, such as access to phone, camera, and contacts, are requested with user consent for specific features but are not mandatory for using the app's core services.
