고객관리 노트 (Customer DB)

When running a business, you often find yourself scattering customer information, consultation details, and contact information across notepads, KakaoTalk messages, and photos.

Customer Management Notes is an offline customer management app designed for business owners and the self-employed. It provides: ✔ Easy customer records, ✔ Excel file storage, and ✔ Data backup/recovery when changing devices.

Data is stored solely on your phone, without being transferred to a server. You can then export it to an Excel file whenever needed, for organizing, printing, and archiving.

Even if you change or reset your phone, you can safely restore customer data using a backup ZIP file, ensuring you never lose important customer records.
