Cookies are files saved on your phone, tablet, or computer when you visit Plesk. They are used to make Plesk work smoothly and to provide information to the Plesk company.

Two types of cookies exist:

• Session cookies. Session cookies are stored in temporary memory and they are not kept after a browser is closed. Session cookies do not collect information from your computer. They typically store information as a session ID, which does not personally identify the user.
• Persistent cookies. Persistent cookies are stored on your hard drive until they expire (persistent cookies have expiration dates) or until you delete the cookies. Persistent cookies collect user-identifying information, such as web surfing behavior or user preferences for a specific website.

Additionally, a website might use external services, which also set their own cookies, known as third-party cookies.

Plesk and Plesk extensions use the following types of cookies:

• Cookies that help us to improve the product
  We use anonymous tracking cookies to collect information on how you use Plesk. It helps us make Plesk better. Tracking cookies do not identify anyone. They store anonymized information about Plesk pages you visited, time you spent on them, and page objects you clicked on.
  We do not share the collected data with third-party services.
• Cookies that help with our communications and marketing
  These cookies collect information about your Plesk preferences and help us provide you with personal recommendations.
• Strictly necessary cookies
  These cookies enable core functions such as security, network management, and accessibility. They always need to be on. Necessary cookies also include functional cookies that are in charge of personalization and usability improvements (for example, language settings, font size, prefilled forms).
  You may disable necessary cookies in your browser settings but this may affect Plesk.
  

The tables below explain the cookies we use in more detail.

You can change your cookie preferences in Plesk at any time. To do so, go to Tools & Settings > Cookies (under "Plesk"), turn cookies on or off, and then click Save. You may need to refresh your page for your settings to take effect.

Deleting cookies

To delete all cookies on your device, clear your browser history. This will remove all cookies from Plesk, Plesk extensions, and from all websites you have visited.

Note: If you delete cookies, you will lose certain saved information (for example, saved login details and website preferences).

See how to manage and/or delete cookies using browser settings.

Managing site-specific cookies

To fine-tune site-specific cookies, check the privacy and cookie settings in your browser.

Blocking cookies

You can set modern browsers to prevent any cookies being placed on your device. After that, however, some services and functions may not work properly (for example, profile logging in). If that's the case, you can manually adjust the corresponding preferences each time you visit a particular website or page.
