How to clear all cookies on an Android device to troubleshoot browsing issues or secure your personal information

• You can clear the cookies on an Android device by heading to your browser's settings and deleting your browser data.
• Cookies are an essential part of how the web works, but you may need to clear cookies to troubleshoot browsing issues, or for privacy or security reasons.
• You can disable cookies entirely, but most websites will not work properly.

Cookies are data files stored on your device that makes the web work smoothly and efficiently, allowing websites to offer various kinds of personalization and ease of use. Cookies remember your login credentials so you don't have to sign into the same sites over and over, for example, as well as remembering personalization details and the content of your shopping cart.

Sometimes, though, you might want to clear your cookies on your Android device. You may need to free space, troubleshoot a glitch with a website, or you're simply concerned about your privacy or security. Whatever the reason, you can clear your cookies pretty easily.

1. Start the Chrome app.

2. At the top right, tap the three-dot menu and tap Settings.

3. Tap Privacy and security.

4. Tap Clear browsing data.

5. Make sure Cookies and site data is selected, and then tap Clear data.
