캐다 is a data trading platform where users can participate in data projects and contribute to creating unique and valuable data. It allows users to easily provide data and earn rewards, which can be used for research and the development of new services. The platform ensures that all data is anonymized, making it safe and secure for users to share their information.

One of the key features of 캐다 is the ability to join various data collection projects. Users can browse through the available projects and choose the ones they are interested in. After participating in the data collection process, users can receive rewards based on their contributions.

Another useful feature is the "내 캐다" (My 캐다) section, where users can review the details of the projects they have participated in. This section provides information on the data they have provided and how it has been utilized.

캐다 also offers a convenient way to exchange the earned rewards for real money. Users can simply go to the "환전하기" (Exchange) section and transfer their 캐다머니 (캐다 money) to their personal bank accounts.

The app only requests necessary permissions, such as access to the camera for image data projects, phone number for registration and account security, and location for location-based projects. These permissions are used solely for the stated purposes and not for any other purposes.

With 캐다, users can actively participate in data projects and contribute to making a positive impact on the world while earning rewards for their valuable contributions.
