리멤버Call is an Android app designed to display the business card of the caller on your phone screen. This app is compatible with Android 9.0 and above. To use this feature, you must first update the '리멤버' app to the latest version and log in to your account. Once you've done that, you can link your '리멤버' account with the '리멤버Call' app and complete the authorization process.

This app requests permission to access your phone and call records to display the caller's business card. Additionally, it also requires permission to display the business card on top of other apps and to turn off battery optimization. Please note that the caller's phone number is sent to the server when a call is received to retrieve the business card information. However, this information is used solely for this purpose and is not stored on the server.
