Cookie Policy

Our KLA Foundation Privacy Policy and EEA+ Supplemental Data Protection Law Disclosures explain how we collect and use personal information and what choices you have. This KLA Foundation Cookie Policy (“Cookie Policy”) describes how cookies and similar technologies are used on the websites owned or operated by the KLA Foundation (the “Foundation”).

This Cookie Policy contains the following:


This Cookie Policy serves as a notice and provides you with the information that the Foundation is required to give website users about how the Company uses cookies. This notice may be supplemented by additional cookie notices, or terms, provided on certain areas of our policy or during interactions with you.


Cookies are small files which are downloaded to your device when you visit a website. The cookie then sends information back to the originating website on each subsequent visit, or to another website that recognizes that cookie. Cookies are useful because they allow a website to recognize a user’s device. You can find more information about cookies at: and

Cookies do lots of different jobs, like letting you navigate between pages efficiently, remembering your preferences, and generally improving the user experience.


Cookies are either first-party or third-party cookies:

  1. First-Party Cookies: First-party cookies are placed by the website operator. For example, first-party cookies on our Site are cookies placed by the Foundation.
  2. Third-Party Cookies: Third-party cookies are cookies placed by a third party. For example, we use a third-party service provider called Google Analytics to analyze how users use our Site. Google Analytics collects de-identified information about usage, such as how long users stop on a web page and route they took through the Site. Google Analytics places cookies to collect this usage information.

The Foundation uses both first-party and third-party cookies on our Site.

Cookies are also often categorized by function.

Information collected:

Our cookies collect several types of information, including information about your usage of our Site, device identifier, screen resolution, browser identifier, city, state, region, language, service provider, link from which a user comes to the Site, links on the Site, Site pages visited, and length of time on a Site page, and your IP address. An IP address is the number assigned to your device, for example your laptop or mobile phone, when your device accesses the internet. Your device may have a static IP address, which means that your device always has the same IP address or it may have a dynamic IP address, which means that the IP address changes each time the device accesses the internet.

Strictly necessary cookies do not require your consent under the laws of the European Economic Area, the United Kingdom, or Switzerland. The legal basis under the laws of the European Economic Area, the United Kingdom, or Switzerland for the collection and further processing of information through the use of strictly necessary cookies is contract performance (Art. 6 (1) lit. b GDPR/UK GDPR) (if we concluded a contract on the use of the website with you) or legitimate interests of us or third parties (Art. 6 (1) lit. f GDPR/UK GDPR), such as the provision of a functioning website.

The other categories of cookies require consent before they can be placed on your device. The legal basis under the laws of the European Economic Area, the United Kingdom, or Switzerland for the collection and further processing of information by such cookies and similar technologies is your consent (Art. 6 (1) lit. a GDPR/UK GDPR).

To the extent information collected through cookies is individually identifiable, we treat it as personal data in accordance with our Privacy Policy.

Location of information processing:

The information collected by our cookies is processed in servers located in the United States.

California notice provisions

California residents, see our separate CCPA Disclosures here.


You can choose how cookies are used on our Site if you are located in the European Economic Area, the United Kingdom, or Switzerland.

You may reject cookies at any time with future effect here. Such a withdrawal will not affect the lawfulness of the processing prior to the withdrawal of consent. The Help menu on the menu bar of most browsers will also tell you how to prevent your browser from accepting new cookies, how to have the browser notify you when you receive a new cookie, and how to disable cookies altogether. For more information on using browser settings to reject cookies, please visit

You should note that rejecting cookies may mean that any preferences you set on the Site will be lost and that the Site may not work as well. Please see the cookies charts above for more information about the particular cookies. In addition, using the browser settings to reject cookies may also cause your browser to reject cookies from all websites, not just our Site.


If you have any questions about our Cookie Policy, we’ll do our best to answer them. Contact us at: [email protected].


If we change our Cookie Policy, we will post those changes on this page and update the Cookie Policy modification date. If we materially change this Cookie Policy in a way that affects how we use or disclose your personal information, we will notify you by prominently posting a notice of such changes before making them and by stating the effective date of the changes.
