Clearing cookies on your Android device achieves a few things. First, deleting cached images and files frees up space on your phone that’s been taken up by temporary files. Regularly clearing out these files is also paramount for staying on top of your personal security. Each cached file is a piece of your digital footprint, and removing this trace lowers the likelihood of cybercriminals going after your data. Learn how to clear the cache and cookies on popular Android mobile browsers like Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera.

What does it mean to “clear cache and cookies?”
Clearing the cache and cookies is the process of removing temporary files from a device to clear out space, resolve performance issues, and fix issues with mismatched website versions and histories. Each time you open a browser and start a new session, it remembers certain information about you, like which sites you visited before, what accounts you signed in to, or what region you’re in. Regular deletions help fix loading issues if your temporary data doesn't match the updated website version.
Although the terms cache and cookies are often used side by side, they refer to different aspects of browsing data. Cookies are temporary files that help websites and apps remember your browsing preferences. Websites also use cookies to monitor your activity and store some information about your identity. If exposed, this information could be misused by cybercriminals. Deleting your cookies can lower the likelihood of your personal data being exposed.
The cache stores website resources like images, fonts, or scripts to help websites load faster each session. Deleting temporary files stored in the cache helps refresh the sites efficiently and avoid loading issues.
Clearing the cache typically doesn’t log you out of websites. Deleting cookies, on the other hand, ends your existing login sessions and starts a brand new session, erasing any history of your previous browsing. In some cases, deleting cookies can also erase your login credential autofill data.
Clearing the cache and cookies can impact website and app loading speed. The browser has to download all data anew, which can make websites load more slowly and increase your data usage. However, in the following sessions, the websites access temporary data to load quickly until the next cache reset.
Why should you clear your cache and cookies?
Knowing how to clear your cache and cookies comes with the understanding of why this process is necessary. Temporary files stored in your cache build up, taking up unnecessary space and causing loading issues when websites or apps are updated. This can go against the cache’s purpose of making websites load faster, causing display issues instead.
Deleting cookies is a matter of privacy. Cookies are stored on your browser as text files that contain all information about your behavior as a site’s user. This information ranges from more surface-level details like your language and display preferences to more precise information like your location or username.
If a cybercriminal were to steal your phone and access your cookie files, they could use that information to identify who you are based on your personal data. They can then impersonate you online under your usual usernames or even your actual legal name.
Clearing cookies on Chrome
You have two options to clear browsing data on Chrome. The first is to delete broader history via the “History” section:

Select “Delete data.” Keep in mind that if your Google account is synchronized on mobile and desktop, both the web browser and Android cookies will be deleted.
Alternatively, you can quickly clear the cache by selecting “Delete browsing data” in the menu:
In Chrome, tap the three dots at the top right corner and select “Delete browsing data.”

Select “Settings.”
Scroll down to “Privacy and security” and select “Delete browsing data.”
Check the boxes to select which browsing data to delete. By default, all tabs will be selected — open tabs, history, cookies and site data, cached images and files, site permissions, and downloads.
Tap “Delete browsing data.” You will see a pop-up screen asking you to confirm the process. Select “Delete” to proceed.
Clearing cookies on Microsoft Edge

In the profile pop-up, tap the gear icon on the right side to access settings.
Select “Privacy and security.” Then, tap “Clear data.”
Check the boxes to select the data you want to delete. Ensure you include the “Cookies and site data” box.
Tap “Clear data” to confirm.
Managing your Android device after clearing the cache
Some browsers allow you to clear data on exit, meaning each time you start a new session, the app will automatically delete cookies on Android. However, if you frequently close the browser and don’t want a clean slate each time, you can also safely manually clean up your Android device yourself once or twice a month.
Keep in mind that when you remove cookies on Android, you might have to log back in to some of your accounts. Practically all browsers also let you delete saved passwords, which can lead to loss of credentials. To save yourself the hassle of manually reentering each password and avoid losing your data to a mistap, consider using a third-party password manager over the built-in browser manager.
With a password manager like NordPass, you can easily create, store, and autofill your credentials. All your login credentials are protected with XChaCha20 encryption and zero-knowledge architecture, ensuring they stay safe and within your reach. You can store unlimited passwords, passkeys, secure notes, and personal documents and access them on your Android, iOS device, desktop, or web browser. Keep your browsing data up to date and don’t let login processes discourage you from routine security practices.
