勤之助タイムレコーダー is a Chrome extension designed to simplify the process of clocking in and out on the cloud-based attendance management system, "勤之助", developed by 万屋一家.

Normally, users have to log in and out of the system each time, which can be time-consuming and inconvenient. However, with this extension, users can stay logged in, allowing them to quickly and easily clock in and out without any hassle. Additionally, the extension includes a main menu, providing direct access to features like attendance records and various applications.

To get started, simply add the extension to your Chrome toolbar. Click on the extension icon and open the options to set up your login information for 勤之助. (The login information is securely stored in your browser and only used for logging into 勤之助. It is also compatible with Chrome sync.)

Once your login information is set up, the extension icon will display a badge indicating your current status:

• Yellow: Not in the office
• Green: Clock in
• Blue: Clock out

Clicking on the icon will display options for "Clock in", "Clock out", and other menus. Enjoy the convenience of managing your attendance with just a click of a button.
