Cookies aren’t always the delicious answer to a more comfortable online browsing experience. In some cases, they can slow down your device and put your personal information at risk.

If you’re keen on staying safe while browsing the web, you need to understand how cookies work on Android, and what they do. Learning how to clear cookies on an Android phone can prevent or even solve some common issues, as well as protect your privacy. Let's get started.

What Are Cookies, and Why Should You Delete Them?

Cookies are text files saved by websites that store information about your visit and they work similarly on PC and Android. Cookies track the information you’ve configured on each page, including:

• Individual login information
• User browsing preferences
• Customized advertising
• Shopping tendencies

While cookies are generally harmless and provide quite a bit of convenience, companies like Facebook and Twitter, along with advertisers, can use them to track your browsing activity. The decision to clear your cookies depends heavily on the sites you visit.

Sometimes it’s hard to tell whether a website you’re visiting is safe. Typically, you want to avoid accepting third-party cookies or those on unencrypted websites. Third-party cookies are those generated for companies that aren't the owner of the website you're visiting. These are usually created via scripts and are typically for advertising purposes.

Unencrypted websites don't protect information exchanged between you and the page. Here, accepting certain cookies can expose your activity on the site to anyone with access to those cookies.

If you’ve already agreed to cookies in these cases, there’s no need to fret, as you can clear them to be safe. In some cases, clearing cookies can fix bugs you encounter while browsing the web. Luckily, clearing your cookies on Android is a simple process. Let's take a look at how to clear cookies on some of the best web browsers for Android.

It’s important to keep in mind that deleting cookies will log you out of all your online accounts on that browser. You’ll need to log back into your accounts on websites manually afterward.
