Where Android stores cookies and why you might want to remove them

Cookies are small files that websites store on your Android device to remember information about you — your login details, what you put in a shopping cart, sites you've visited. They live inside your web browser, not scattered across your phone like regular files. When you delete cookies, you're clearing out that stored information, which can speed up your browser, free up a small amount of storage, and remove records of where you've been online.

The steps to delete cookies depend on which browser you use. Chrome, Firefox, Samsung Internet, and Opera all store cookies in different places and use slightly different menus. The process takes less than a minute once you know where to look. You can delete all cookies at once or choose a date range — for example, cookies from the last week only — and you'll be logged out of most websites afterward, so you'll need to sign back in the next time you visit them.

Key Takeaways

  • Cookies live inside your web browser app, not in your phone's main file storage, so you delete them from within the browser itself.
  • Chrome, Firefox, Samsung Internet, and Opera each have their own menu for clearing cookies, usually found under Settings or History.
  • You can delete all cookies at once or choose a date range — for example, cookies from the last week only.
  • Deleting cookies will log you out of most websites, so you'll need to sign back in the next time you visit them.

Deleting cookies in Chrome on Android

Open the Chrome app and tap the three vertical dots in the top right corner. Scroll down and tap Settings. Tap Privacy and security, then tap Clear browsing data.

A window will appear with several checkboxes. Make sure Cookies and site data is checked — it usually is by default. At the top of the window, you'll see a dropdown that says All time. You can leave it there to delete all cookies, or tap it to choose a shorter time period like Last hour, Last 24 hours, or Last 7 days. When you're ready, tap the blue Clear data button at the bottom. Chrome will delete the cookies when ready, and you'll be logged out of most websites you were signed into.

Deleting cookies in Firefox on Android

Open Firefox and tap the three horizontal lines (the menu button) at the bottom right of the screen. Tap Settings. Scroll down and tap Delete browsing data.

You'll see a list of data types with checkboxes. Find Cookies and make sure it's checked. Below that, you can choose what time period to clear — Everything will delete all cookies, or you can select Last hour, Last 24 hours, or Last week. Tap the red Delete browsing data button to finish. Firefox will remove the cookies right away and log you out of signed-in accounts.

Deleting cookies in Samsung Internet

Open Samsung Internet and tap the three horizontal lines at the bottom right. Tap Settings. Tap Privacy. Tap Delete browsing data.

Check the box next to Cookies and site data. You can choose to delete all cookies or select a time range from the dropdown at the top. Tap Delete to remove them. The browser will clear the cookies and sign you out of websites when ready.

Deleting cookies in Opera on Android

Open Opera and tap the red O icon at the bottom right. Tap Settings. Tap Privacy. Tap Clear browsing data.

Make sure Cookies is checked. Choose your time range — All time removes everything, or pick a shorter window. Tap Clear data to finish. Opera will delete the cookies and log you out of any sites where you were signed in.

What happens after you delete cookies

Once cookies are gone, websites won't remember you until you visit them again and they create new cookies. You'll need to sign back into email, social media, banking apps accessed through a browser, and shopping sites. Your browsing history remains unchanged — deleting cookies does not erase the list of sites you've visited, only the information those sites stored about you.

If you want to prevent cookies from being stored in the first place, most browsers have a private or incognito mode. In Chrome, tap the three dots and select New incognito tab. In Firefox, tap the menu and select New private tab. Websites can still see you're visiting, but they won't store cookies that follow you to other sites.

Clearing cookies on a schedule

If you delete cookies regularly, you can set your browser to clear them automatically. In Chrome, go to Settings > Privacy and security > Clear browsing data, then check the box that says Delete browsing data when you close Chrome. Firefox has a similar option under Settings > Privacy > Delete browsing data on quit.

This way you don't have to remember to do it manually. Every time you close the browser, it will remove cookies automatically. You can still choose which types of data to clear — if you want to keep your browsing history but delete cookies, uncheck the history box and leave only cookies checked.

Frequently Asked Questions

Will deleting cookies delete my passwords?

No. Passwords are stored separately from cookies. Deleting cookies will log you out of websites, but your saved passwords remain in your browser. When you sign back in, the browser will offer to fill in your password automatically.

Can I delete cookies from just one website?

Most Android browsers don't offer a straightforward way to delete cookies from a single site. Your best option is to use private or incognito mode when visiting that site, which prevents cookies from being stored in the first place. Otherwise, you'll need to delete all cookies and then sign back into the sites you want to stay logged into.

Does deleting cookies free up a lot of storage space?

No. Cookies are tiny files — usually just a few kilobytes each. Even if you have thousands of them, they take up far less space than photos, videos, or apps. Deleting cookies won't noticeably improve your phone's storage unless your device is extremely full.

What's the difference between cookies and browsing history?

Browsing history is the list of websites you've visited. Cookies are information those websites stored on your device. You can delete one without deleting the other — most browsers have separate options for each in their clear data menu.

If I delete cookies, will websites load slower?

Slightly, the first time you visit them after deleting cookies. Websites use cookies to remember your preferences and login information, so they don't have to load that data from scratch. Once you visit a site again, it will create new cookies and load at normal speed.
