Choosing which cookies to keep

A cookie is a small file that a website can place on your hard drive. It contains information about when you visited the site, and may contain tracking and settings information. For more information about cookies, see the Wikipedia entry.

Note: Flash cookies (which are used by Adobe Flash) are cleaned differently by CCleaner. See this topic for more information on Flash cookies.

You may choose to delete cookies for privacy reasons. Be aware, though, that some sites may forget your login data if you delete their cookies. Others will simply replace the cookie the next time you visit.

By default, when you run the Cleaner, CCleaner deletes all of the cookies for all of your Web browsers (Internet Explorer, Mozilla Firefox, Safari, Opera, and so on) except those in the Cookies to Keep column, which can be found in Options > Cookies.

The Cookies to Keep column contains cookies which CCleaner does not clean by default because they:

  1. Are from a frequently used website.
    Deleting these cookies might mean you are logged out of the websites you use most, such as Facebook.
  2. Are required to improve your experience.
    CCleaner Free users may sometimes be shown contextual offers (for example, to install Google Chrome or Avast antivirus). So that only relevant offers are displayed, a cookie is stored on the user’s machine. To ensure that users are only ever shown a relevant offer, CCleaner will always try to keep or replace these cookies.

Deleting these cookies might mean that you see offers more often than intended because the cookie that records offer display frequency has been removed during cleaning.

There are three ways to manage the cookies on your PC while still making full use of CCleaner.

Option 1: To keep all cookies on your PC

  1. In CCleaner, click the Cleaner icon on the left.
  2. On the Windows tab, under Internet Explorer, clear the Cookies check box.
  3. If you have no other Web browsers installed, you have finished. If not, click the Applications tab.
  4. Under each browser listed, clear the Cookies check box.

From this point on, whenever you run the Cleaner, it will retain all cookies from these browsers.

Option 2: To keep certain cookies on your PC

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. You’ll now see a list of cookies from all the browsers you have installed on your system. The left column displays all cookies available to clean and the right column displays a list of Cookies to Keep.
  3. To keep cookies, move them to the Cookies to Keep column by selecting cookies and clicking the right-arrow button. You can select multiple cookies by using CTRL+click, or select a set of cookies in a row by clicking the first one and then SHIFT-clicking the last one.

Option 3: To delete certain cookies on your PC manually

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. This list displays cookies from all the browsers you have installed on your system.
  3. To remove a specific cookie, right-click on it and select Delete now. This can also be done for multiple cookies by using CTRL+click, or select a set of cookies in a row by clicking the first one and then SHIFT+click the last one.

Not sure which cookies to keep?

CCleaner’s Intelligent Cookie Scan can help you by adding some popular websites to the 'cookies to keep' list. This stops you from being logged out of websites like Facebook and Twitter, or email providers like Gmail and Yahoo.

To use Intelligent Cookie Scan:

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. This list displays cookies from all the browsers you have installed on your system.
  3. To keep the cookies that store login data for the websites you use (for example web mail) click right mouse button on the Cookies to Delete column and choose Intelligent Scan from the menu list.
  4. Dialog box Intelligent Cookie Scan will appear and ask you to allow CCleaner to keep your persistent logins for websites. Selecting No cancels the operation. Selecting Yes (Recommended) keeps all logins for websites and all available cookies form the Intelligent Cookie Scan list appear on the Cookies to Keep list.

Notes:

  • CCleaner Free users may sometimes be shown contextual offers (for example, to install Google Chrome or Avast antivirus). So that only relevant offers are displayed, a cookie is stored on the user’s machine. CCleaner will always try to keep or replace these cookies because deleting them might mean that you see offers more often than intended (because the cookie that records offer display frequency has been removed during cleaning).
  • If you use the method in Option 1 to keep all cookies on your PC, the cookies in the Cookies to Delete column will not be deleted.
  • If you have a long list of cookies, you can easily search through them for the ones you want. Click inside the Search box and type a few letters in the cookie's domain name. For example, typing HOO will return cookies for Yahoo.com.
  • If you want to add a domain entry that hasn't appeared on your PC yet, right-click a blank part of the Cookies to Keep list, and then click Add. Type the domain name in the dialog box and then click OK.
