By default, each Browser instance stores all user data such as history, cookies, cache on disk. Since 6.8 you can configure Browser instance to store all user data in memory (Chromium's "Incognito" mode), so that all user data will be cleared once your Java application is terminated.

The following example demonstrates how to configure Browser instance to work in "Incognito" mode and store all user data in memory:

import com.teamdev.jxbrowser.chromium.Browser;
import com.teamdev.jxbrowser.chromium.BrowserContext;
import com.teamdev.jxbrowser.chromium.BrowserContextParams;
import com.teamdev.jxbrowser.chromium.StorageType;
import com.teamdev.jxbrowser.chromium.swing.BrowserView;

import javax.swing.*;
import java.awt.*;

 * This sample demonstrates how to configure Browser instance
 * to use in-memory data storage.
public class IncognitoModeSample {
    public static void main(String[] args) {
        // No user data will be stored to the "user-data-dir" folder.
        // This directory will be used for internal purposes
        // on macOS and Linux platforms.
        BrowserContextParams params = new BrowserContextParams("user-data-dir");

        BrowserContext browserContext = new BrowserContext(params);
        Browser browser = new Browser(browserContext);
        BrowserView view = new BrowserView(browser);

        JFrame frame = new JFrame();
        frame.add(view, BorderLayout.CENTER);
        frame.setSize(700, 500);
