How and why do we use Cookies?

A "cookie" is a small data file that our site transfers to your device through your web browser that enables the site systems to recognize your browser and subsequently capture and remember certain information. We use both session cookies, which are erased upon closing your web browser, and persistent cookies, which may be stored for a certain period of time.

We use cookies to help us to improve your overall web experience when on our site. Cookies may enable us to remember and process the items in your shopping cart, to understand and save your preferences for future visits, to compile aggregated and anonymized data about site traffic and site interaction and to reflect geographically accurate information regarding pricing, in the jurisdictions such activity is not prohibited in. In some cases, where permitted, we may contract with third party service providers to assist us in better understanding our site visitors. An example of such third party is Google Analytics. However, those service providers are not permitted to use any personal data collected on our behalf except to help us conduct and improve our business. In limited cases, we may allow such service providers to utilize aggregated, anonymized data for analytical purposes. We do not engage in "cookie swapping" or the sale of cookies to third parties.

You can configure most browsers to prevent them from accepting new cookies or to disable cookies altogether. We recommend that you leave cookies enabled as they allow you to take advantage of some of our essential website functionality. For example, if you block cookies, you may not be able to shop for products on our site or chat with our representatives online.


In what way and on what legal basis do we use the personal data that we receive?

We limit the use of the personal data that we collect from you. We might use your personal data in connection with the following business purposes:

  1. Improve user experience on our websites, as allowed based on applicable law;
  2. Accept and fulfill orders and to meet our contractual obligations relating to such orders as well as answering any inquiries or requests related to potential orders or orders for product, service, support and warranty related matters;
  3. Marketing purposes and to provide additional information regarding our products and services to enable individuals to explore and compare the functionality and features of our products;
  4. Comply with certain legal or regulatory obligations applicable to our business;
  5. If you have given us your consent to process the data, then, we may use the data for purposes of sending marketing materials to you; and
  6. We store and process your information about your use of our website for purposes of misuse detection and tracking. Additionally, we store personal data that enables us to effectively defend ourselves in the event of a possible legal dispute, to the extent permitted by applicable law.

Which recipients and third parties receive the collected personal data?

We are not in the business of selling your personal data. We may in some cases have a need to share your personal data in connection with our business operations. Examples of this might include:

  1. Sharing personal data with employees that have a need to know that personal data in connection with a legitimate business purpose specified in the section above, such as fulfilling an order or answering a customer inquiry.
  2. Sharing personal data with our organizational subsidiaries and affiliated entities, including new businesses acquired through acquisition. Alternatively, in the event that we divest or transfer a technology, business unit or entity, we might be required to share or transfer that personal data to the acquiring entity.
  3. Providing personal data to third parties that are bound by our instructions and are providing products or performing services on our behalf in connection with our business operations. We do not enable our service providers to use that personal data except as required to provide the product or service requested by MKS. Such services may include analysis on website hits, trends and traffic, hosting and IT storage services in which we might store customer contact information submitted (e.g., CRM or ERP systems), marketing vendors that help us to provide you with promotional offers, newsletters and product information, and suppliers of component materials or related services or logistics providers that help us deliver product to you.
  4. Disclosing personal data where we believe it is required in order to comply with the law or to protect users and customers. For example, this may include exchanging information with companies and government agencies for the purpose of fraud protection, credit risk reduction, or compliance with export control laws.

Where personal data is transferred to non-related third parties or any country outside the EU/EEA within the above mentioned cases, appropriate safeguards are provided to safeguard such data transfer and data protection clauses are agreed upon by the recipients, the content of which is made available to you upon your request.
