Website Privacy Notice 


1. Introduction

This privacy notice sets out how Knowles Corporation and our subsidiaries ("we", "us" or "Knowles") will process your personal information when using or accessing our website, content, apps and services (each a “Service”).

This notice explains why Knowles collects information concerning the users of the Services (each a "user", "you" or “your”), what type of information we collect and how we use that information.  This Privacy Notice applies to any such information collected via any Service which displays it (or a link to it).

Additional information for users located in the European Economic Area (“EEA”), Switzerland and the UK about their rights and other information can be found in the EEA Annex to this Privacy Notice.

This notice was last updated on 17 April 2024.

2. What data we collect

When a user interacts with any of the Services, Knowles may collect certain data about that user.  This data falls into 2 broad categories: (i) data about a user themselves, which the user gives us; and (ii) data about the way a user interacts with the Services or Services, which is collected by us electronically (collectively "User Information").

We collect the following User Information in accordance with applicable law:

  • Information that users provide to us, directly or via a third-party registration service for the purpose of registering with us or our group companies
  • Information users provide to us when users interact with our customer service team
  • Information about user interactions with our Services, and any direct communications the user receives from us (such as emails)
  • Device IDs or unique identifiers, location data, device and software characteristics (such as type and configuration), connection information, statistics on page views, referral URLs, ad data, website and app navigation, IP address and standard web log information
  • The language choices made by users in relation to their use of the Service, which may include information relating to their location when using the Service
  • The details of any third-party digital property (such as a website) that referred or linked a user to the Services
  • Information about how users behave on our Services (such as the type of content they view, how frequently, at what times etc).

We may also collect personal information from a variety of third-party sources.  These include service providers who allow us to verify, enhance, or supplement the User Information collected on our Services, and business partners to whom we are offering a service. 


3. How & why we use the data we collect

We use the User Information for three main purposes: (i) to operate and improve the Services and to ensure that we can provide the Services; (ii) to optimize the content on the Services; and (iii) send marketing and show advertising to our users. 

We will use the User Information to do one or more of the following things: 

  • Administer our Services
  • Recommend goods, services or promotions which may be of interest to the user
  • Supply services purchased via our Services
  • Send notices and invoices to users, and collect payments from them
  • Deal with enquiries and complaints
  • Comply with any legal or regulatory requirements and otherwise to respond to any relevant regulator or competent authority as required by law
  • Understand user trends and patterns
  • Develop aggregate analysis in respect of our users and business intelligence that enable us to operate, protect, make informed decisions and report on the performance of our business


Much of the User Information that we collect, and most of the information we employ in connection with advertising, is obtained via the use of cookies and similar technologies.  Cookies are usually a string of numbers and/or letters that a website transfers to a User's hard drive. Similar technologies include pixel tags and web storage and other technologies, and we refer to all these things as “cookies” in this section. The cookies enable the Services to "remember" you, either for the duration of your visit (session cookies) or for repeat visits (persistent cookies). 

On this Services, we use the following types of cookies:

 Strictly necessary cookies - These cookies are essential to enable the user to navigate around the Services securely and to provide the user with Services they have specifically requested. 

• Functionality cookies - These cookies enhance the functionality of the Services by storing user preferences. For instance, they can remember your name and location, if you provide this information and the types of content you are interested in.

• Performance cookies - These cookies improve the performance of the Services. For instance, they help pages load quicker.

• Analytics cookies - We use third party analytics services such as Google Analytics and others. Your IP address and other information will be collected by automated means to evaluate your use of the website, compile reports on website activity, identify user patterns and provide related services. For more information about how Google Analytics uses your information please click here. In addition, authentication and tracking logs will be used to compile user statistics.

 Targeting/advertising – These cookies help us serve relevant advertisements and implement frequency capping procedures.

These types of cookies may also be placed on the Services by our business partners or service providers. 

If you register with us or if you continue to use our Services, you agree to our use of cookies. In some cases, when you arrive on our Services a pop-up message will appear asking for your consent to place advertising cookies on your device as required by applicable law.  In order to provide your consent, please click ‘OK’. Once your consent has been provided, this message will not appear again when you revisit, unless you delete cookies via your browser settings or otherwise. 

Most web browsers automatically accept cookies, but if you prefer, you can change your browser to prevent that, or opt-out as explained below. You may not be able to take full advantage of our Services or use certain functions if you disable cookies.

5.Disclosure of User Information

We may share User Information with any member of the Knowles group where this is necessary for business administration purposes in accordance with applicable law.  We may also allow other members of the Knowles group to contact users with relevant offers, competitions and latest news (where they have consented to doing so, if required by applicable laws).

We may also share User Information with selected third parties including:

• Business partners, suppliers and sub-contractors in connection with providing Services to our users
• Advertisers and advertising networks that require the data to select and serve relevant adverts to the user 
• Analytics and search engine providers that assist us in the improvement and optimisation of the Services 
• If we decide to sell the business operating the Service or it is integrated with another business, we may disclose User Information to our advisers and any prospective buyer’s advisers as well as to the new owners of the business
• If we are under a duty to disclose or share a user's personal information in order to comply with any legal obligation, or in order to enforce or apply our terms
• In order to prevent fraud, cheating and money laundering we may disclose User Information and betting and gaming history to third parties including, but not limited to, any relevant regulator, gaming and sporting bodies, financial institutions and law enforcement agencies or any other body that deals with the investigation of alleged offences.

Where relevant, we will disclose User Information and anonymized information associated with a user's use of and interaction with the Services to the partner on whose behalf we operate that Services, for the purposes of marketing and advertising, and to promote their own products and services.  

6.Your right to opt-out

If you, or another user of your device, wish to withdraw your cookies consent at any time, you have the ability to accept or decline cookies by modifying your browser setting. You may also go to or if you are in Europe, or to if you are anywhere else for instructions on how to disable cookies. You may opt-out from Google Analytics here. In some instances, when you opt-out, a new cookie (Opt-Out-Cookie) is placed in your web browser. This tells the third party provider to cease data collection from your browser and prevents advertisements from being delivered to you.

7. Security

We understand that the security of your User Information is important to you.  When handling User Information, security is paramount and we seek to ensure that User Information is protected through appropriate technical and organizational measures.  

We use reasonable administrative, logical and physical controls, including password protection, to safeguard your User Information against loss, theft and unauthorized access, use or modification. Unfortunately, the transmission of information via the internet is not completely secure. Although we will do our best to protect your User Information in accordance with applicable law, we cannot guarantee the security of your User Information.

8. International data transfers

Information that we collect may be stored and processed in and transferred between any of the countries in which we operate in order to enable us to use the information in accordance with this notice.

Information which you provide may be transferred to our group companies, commercial partners, suppliers or agents located outside your country as set out in paragraph 5 above. We will ensure adequate protection of personal data transferred outside of your country as required under applicable laws. For example, if you are located in the EEA, Switzerland or in the United Kingdom, we may enter into model clauses with the recipient. You may contact us for a copy of the safeguards which we have put in place to protect your personal data in these circumstances.

In addition, personal information that you submit for publication on the Services will be published on the internet and may be available, via the internet, around the world. We cannot prevent the use or misuse of such information by others.

11. Changes

We reserve the right to change the practices described in this Privacy Notice at any time by posting an updated Privacy Notice.  Please check here periodically.  If we amend this notice, your continued use of our Services will amount to your acknowledgement of the amended notice.


In order to comply with data privacy regulations in the EEA, Switzerland and the UK, Knowles provides additional information to its EEA, Switzerland and UK based users. 

What is personal data? 

“Personal data” is information about you (a “data subject”) the use of which is governed by applicable data protection laws. It will include any information from which you can be identified, directly or indirectly, in particular by reference to an identifier such as your name, an identification number, location data, an online identifier or other information about your identity. Most User Information will constitute personal data. 

What is the legal basis on which Knowles relies to process your personal data?

On some occasions, we process your personal data with your consent (for example, when you agree to participate in our surveys and other activities or when you give us consent to send you marketing communications (adopting a “double-opt-in” where required) or to deal with your enquiries, as set out in paragraph 3 letter (d)).

On other occasions, we process your personal data when we need to do this in order to fulfil a contract with you (for example, to make available to you the requested content or for billing purposes) or in order to take steps prior to entering into a contract (for example, verifying your information), as set out in paragraph 3 letters (a), (b), (c), (f), (g), (h), (i), (j) and (k). 

We also process your personal data when it is in our legitimate interests to do this and when these interests are not overridden by your data protection rights, as set out in paragraph 3 letters (c), (e), (j), (k), (l), (n) and (o). For example, we may process your personal data in our legitimate interests to ensure that our Services and Services are provided efficiently and in an user-friendly and personalised manner taking into account user feedback, data and profiles, unless consent is required for any such processing under applicable law. We will process personal data to ensure the security of our business and the information of our users, and to ensure the proper and efficient administration of our business. You may contact us for further information.

Finally, we will process your personal data where we are required to do this by law (for example, where we have to fulfil anti-money laundering requirements or disclose information under a court order), as set out in paragraph 3 letters (f), (g), (k) and (m).  

How long does Knowles keep data?

Knowles keeps your data for only as long as required to provide you with the necessary Services and to carry out the processing set out in this notice, and in line with its obligation under applicable law. This means that we will generally not keep your personal information for longer than six years following your last interaction with us, and the retention period will often be shorter. For example, we may keep your information for marketing purposes for a period of 3 years following the termination or expiry of our relationship, or your last contact with us. 

Your rights

Data subjects may ask us for a copy of their information, to correct it, erase it or to transfer it to other organisations at their request. Data subjects also have rights to object to some processing including profiling and, where we have asked for their consent to process the data subject’s data, to withdraw this consent. In particular, data subjects have the right to object to direct marketing at any time. Where a data subject withdraws their consent, this will not affect the legitimacy of the processing conducted prior to your request.  Where we process data because we have a legitimate interest in doing so (as explained above), the data subject has a right to object to this. Where we make a decision based solely on automated processing which significantly affects the data subject, he or she may have the right to contest the decision, express his or her point of view and obtain human intervention. Data subjects have the right to have their data transferred to another provider. 

These rights may be limited in some situations – for example, where we can demonstrate that we have a legal requirement to process your data. 

Please use the contact information set out in our Contact section above. We will aim to acknowledge your enquiries within 72 hours and respond within one month, unless otherwise required by law. 

We hope that we can satisfy queries you may have about the way we process your data. However, if you have unresolved concerns you also have the right to complain to your local data protection authority.
