To configure Google Chrome to automatically clear all site data (cookies and local storage) every time you exit the browser, follow these exact steps:
- Open Chrome.
- Click the three-dot menu (⋮) in the top-right corner and select Settings.
- In the left sidebar, click Privacy & Security.
- Click Site Settings in the main pane.
- Scroll down and click Additional content settings to expand more options.
- Click On-device site data.
- Toggle on Delete data sites have saved on your device when you close all windows.
This setting will ensure that all site data (including cookies and local storage) is deleted each time you close all Chrome windows.
Note:
- This will not clear your browsing history, download history, or passwords—only site data like cookies and local storage. If you want to clear additional types of browsing data on exit, Chrome does not provide a built-in setting for that. You would need to use extensions or configure policies via Group Policy or the Windows Registry for more comprehensive data clearing.
- If you are using a managed (work or school) account, some options may be unavailable or controlled by your administrator.
