About this app

Cosback is a smart rewards platform that automatically earns cashback for every online purchase.
You can get started right away with a simple sign-up process, and simply by making a purchase at a partner brand's online store, you can automatically earn cashback, making it easy for anyone to enjoy the benefits.

Cosback's key features include:

① Automatic Cashback Accumulation
Cashback is automatically accumulated when you access a partner store through the app's in-app browser and make a purchase.
There's no need to enter a separate coupon or earn points, so you can enjoy rewards while shopping as usual.

② Real-time Cashback Check & Withdrawal
You can check your accumulated cashback in real time on My Page, and once you've accumulated 10,000 won or more, you can withdraw it directly to your account.

③ Referral Code Rewards
Invite friends and earn referral rewards.
The default reward is 2.5%, but higher reward rates are available when certain conditions are met, further increasing the value of your activity.

④ User-centric, Simple Structure
Without complex leveling systems or conditional events, cashback is transparently accrued based on actual purchase amounts.
The app securely tracks purchase history to ensure error-free accrual, and user information is thoroughly protected.

⑤ Expanding Diverse Partner Brands
Cashback is offered from a variety of partner brands, including beauty, health, and lifestyle, and will expand to more categories in the future.
Customized benefits are also continuously provided based on user shopping patterns.

Cosback is not just a simple rewards app; it's a practical rewards platform that converts users' spending value into actual cash.
Designed to provide meaningful benefits even with everyday shopping, it's easy for anyone to use.

Download Cosback now and begin a new consumer experience where everyday shopping earns you cashback.
