Account information is kept while your store uses the account, and is deleted when you or your store ask us to delete it.

5. Store information shown in the app

PC status, sales and staff names shown in the app are read from your store's KAFE counter each time you open the screen. Neither the app nor our server stores them.

6. Information stored on your device

The sign-in token (encrypted with the device keystore), login ID, selected store, sort order and app language. They are excluded from device backups and transfers, and are removed when you uninstall the app.

The app contains no advertising or analytics SDKs.
Update checks are handled by Google Play or the App Store under their own privacy policies.
Our servers are located in the Republic of Korea.

8. Your rights

You can ask to access, correct or delete your information, or to stop its processing. Ask your store's administrator (who manages your account in the KAFE counter) or email us at nsm@nsmaker.co.kr.
Accounts are created by your store in the KAFE counter. You cannot sign up in the app.
