This Privacy Policy describes how LLWE collects and processes personal information about you, how we use and protect this information, and your rights.

This Privacy Policy describes the privacy practices of LLWE only and does not cover the practices of other companies. The Digital Services, including the other products and services made available through the Digital Services (collectively, the “Materials”), are made available for informational and entertainment purposes only. 

2. WHAT INFORMATION WE OBTAIN

When you use a Digital Service, we obtain various types of information related to you and your use of the Digital Service or Materials. This data includes personal information that directly identifies you such as your name or contact information as well as information such as online identifiers or cookie-level data that may indirectly identify you. The information we obtain generally consists of information that (1) you provide us about yourself or that we directly collect from you, (2) you provide us about others, (3) automatically collected about your interactions with the Digital Services or Materials, and (4) we get from other sources as described further below.

A. Information we collect directly from you

LLWE asks you to provide information about yourself when you use the Digital Services, including when you create an account, complete a form or subscribe to a mailing list. You may not be able to use certain features if you choose not to submit the requested information.

  • Demographic information (e.g., region, preferred language, topics of interest).

  • Transactional and activity information (e.g., requests, searches or orders).

B. Information automatically collected

The Digital Services automatically log certain information about visits to the Digital Services, such as the number and frequency of visitors, technical information about browsers and devices used to access the Digital Services, and information about crashes or other technical issues. In addition, in accordance with your expressed preferences, we and third parties automatically collect certain information through cookies and similar tools (referred collectively as “Cookies and Similar Technologies”) about your activities over time across the Digital Services as well as across third-party sites, apps or other media. Some Cookies and Similar Technologies assign or collect unique cookie IDs or other identifiers associated with your browser or device. Cookies and Similar Technologies may collect information while you are using the Digital Services or while they are running in the background of your device. More information about the Cookies and Similar Technologies used on the Digital Services, including how to manage your preferences, is set out in the Cookie Policy.

The information automatically collected includes the following:

3. HOW WE USE INFORMATION WE OBTAIN

LLWE uses the information we obtain for the following business purposes:

A. To provide you with the Digital Services. This service includes:

  • Processing your requests regarding the Digital Services and the Materials.
  • Providing customer assistance or technical support.
  • Customizing the Digital Services and Materials, providing recommendations and enhancing the quality and your overall experience with the Digital Services, including by retaining your user preferences, optimizing the presentation of the Digital Services and Materials based on your interests, and for the browser or device you use to access the Digital Services.
  • Maintaining, operating, improving and developing the Digital Services and Materials, and other related products and services.
  • Learning about users of the Digital Services and analyzing how you and others interact with and respond to the Digital Services and Materials, including by measuring and optimizing usage, reliability and performance, conducting market research, performing analytics, and supporting our operations (e.g., for accounting, auditing, financial, or other purposes).

B. To communicate with you. This activity includes:

  • Sending you Materials you have requested or which we believe are of interest to you.
  • Sending you informational messages about the Digital Services (e.g., to confirm your access to the relevant Materials or notify you of changes to a Digital Service).
  • Delivering marketing or promotional communications.
  • Responding to your questions or addressing your requests.
  • Providing you with surveys regarding the Digital Services.


C. For advertising and marketing purposes, including interest-based advertising.

This activity includes:

  • Developing, managing and conducting advertising and marketing campaigns, promotions and offers, including about the Digital Services, Materials and other lucha-related products, services or initiatives.
  • Cross-device linking. If you access the Digital Services from multiple browsers or devices, we, our service providers and third parties may try to establish connections among and link the different browsers and devices you use to access the Digital Services. This helps us provide you with a seamless experience across the browsers and devices you use and serve you with the relevant Materials.
  • Interest-based advertising (also known as targeted or personalized advertising or ads) is advertising based on your interests as inferred from your activities over time on the Digital Services and online services operated by third parties, as well as other information. Interest-based ads consist of text ads, images, animations or videos and are displayed to you based on various factors, including the context of the site or app in which they appear (e.g., sport or travel section), information you provided to the operator of the site or app (e.g., when you created an account), your activities on the site or app (e.g., pages viewed, searches performed or ads clicked), and information such as your demographic, interests and household information.
  • In line with your expressed preferences we, our service providers and third parties use automated means including Cookies and Similar Technologies on the Digital Services and on third-party sites, apps or other media to (a) collect information for interest-based advertising purposes or (b) serve you interest-based ads. When you agree to the use of Cookies and Similar Technologies on the Digital Services, unique identifiers may be associated with your browser or device to support interest-based advertising.
  • We use online and offline information we obtain about you, including your personal information, for interest-based advertising purposes. We aggregate the information we obtain to create audiences that are most likely to respond to ads based on demographic, interests or household information.
  • Interest-based ads may be displayed to you by third parties, such as ad networks or exchanges.
  • There are steps you can take to limit the collection of your information by Cookies and Similar Technologies and the use of your information for interest-based advertising purposes. These steps vary for the web and mobile app environments and are browser and device specific. To learn more about these choices, see the Cookie Policy.


D. To protect our rights or the rights of others
. This protection includes:

  • Detecting, preventing and responding to fraud or potentially illegal activities, misuse of the Digital Services, intellectual property infringement or other violations of law, this Privacy Policy, our Terms of Use or other policies.
  • Performing audits, assessments, and testing or troubleshooting activities.
  • Backing up our systems, including for disaster recovery purposes, and enhancing the overall security of the Digital Services.
  • Complying with and enforcing applicable legal requirements, including legal process such as court orders, warrants, regulatory investigations, or subpoenas, and/or fulfilling contractual obligations.


LEGAL BASIS FOR USING THE INFORMATION

We must have a legal basis to process your personal information. The legal basis will be one of the following:

  • To honor our contractual obligations to you when we use your information to provide you with the Digital Services or Materials. For example, when you purchase a pay-per-view access, subscription or other materials from us, it will be necessary to process your payment details and contact details to confirm and provide your purchases to you. Similarly, when you sign up for a mobile app, we will need to process your registration information so that we can set up your user account and provide the relevant services to you. Failure to provide the information could prevent or delay our ability to provide the requested services. 
  • To comply with our legal obligations when we use your information to protect our rights or the rights of others and when we share your information with other parties where required by law or as necessary to protect our rights. We are required to collect certain information from you when processing your subscription payment for tax or financial reporting reasons. Similarly, local tax law will often require us to keep information about contest or promotion participants for audit and taxation purposes.
  • To meet our legitimate interests when we use your information to provide you with the Digital Services, to communicate with you and for advertising and marketing purposes, including interest-based advertising or when we share your information with our affiliates and subsidiaries, in the context of a corporate transaction or with our business partners, social media platforms and advertisers. Our legitimate interests include improving the Digital Services, our products and services, understanding how you interact with our Digital Services and publications, deriving knowledge to develop new products and services, and customizing the Digital Services by making them more relevant and interesting to you and others. When we process personal information to meet our legitimate interests, we put in place safeguards to help ensure that your privacy is given due regard.
  • We will obtain your consent to collect and use certain types of personal information when we are required to do so by law (for example, in relation to sharing of your information with third parties for their own marketing activities). If we ask for your consent to process your personal information, you can withdraw your consent at any time by contacting us using the details at the end of this Privacy Policy.


Information on our use of cookies and similar technologies

Our Digital Services use Cookies and Similar Technologies to provide our Services, to understand how our Services are used, and for advertising purposes, as explained in this Privacy Policy.

We share your information as and when we believe it necessary or appropriate to protect, enforce, or defend our legal rights, the privacy or safety of our employees, users of the Digital Services or other individuals and entities, or to comply with or enforce applicable law or legal process, including responding to court orders, warrants, regulatory investigations, subpoenas and other requests from public and government authorities.
  7. Corporate Transactions. We reserve the right to transfer any of the information we have about you to proceed with the consideration, negotiation, or completion of a sale or transfer of all or a portion of our business or assets to a third party, such as in the event of a merger, acquisition or other disposition, or in connection with a bankruptcy reorganization, dissolution, or liquidation.
  8. With Your Consent or Otherwise at Your Direction. In addition, we share your information with third parties when you consent to or request such sharing.
