“Data controller” means the natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data; where the purposes and means of such processing are determined by relevant law of the Hong Kong Special Administrative Region of the People’s Republic of China.

The data we collect

The data we collect about you depends on the services that you use and how you use them, and it also depends on your relationship with us: if you are a user, a business partner, a prospect etc.

We will deploy indiscriminate and anonymous means of statistics, including “cookie” and “pixel tag”, to collect and store the data.

“Cookie” is a small text file, including a single or a string of word character(s), and is used as an anonymous mark to distinguish a unique web browser. Cookie can only be read or changed by the website operator(s) or service providers who deploy(s) it. Most of the browsers allow cookies as default, but you can change your browsers setting, and make your browsers reject any third-party cookies, or accept cookies only if you agree. Please click on the “help” button in your browsers to know more about the cookies setting of your browsers.

“Pixel Tag” is a string of code that is displayed as a 1x1pixel graph on the webpage. Pixel Tag allows service providers or third-party operator to read and change the cookies and transfer other data, including which webpage that the user is currently browsing, about the computer that is used to view the webpage, user’s operation system, browser type and other data such as IP address and time.

Other than for business contacts data as provided below, we do collect any information such as email, address, phone number, credit card information etc. The data we hold about you is not data which allows us to know you. We do not process any data in such a way that it could be used, including through a third party, to establish the identity of a user, unless you voluntarily provide those data to us. If you voluntarily share with us your personal data, we will also collect contact information including but not limited to personal name, company name, telephone or mobile number and email address, in order to contact you.

End-user data

We are a company operating in the field of marketing and advertising technology. We provide advertising and analytics services for the benefit of our business customers, giving them the ability to reach users who are most likely to be interested in the products and services of the clients we work for. We collect data from millions of users and use the data collected and processed to inform audience targeting and generation of insights about consumers.

For Europe-based users:

We do not target users in the EU/EEA and it is not our intention to process the personal data of users located there. In order for us to process your data, you will normally have consented and accepted to data processing and accepting cookies or similar technologies from one of the publishers that we collect data from. So, it is possible that when visiting Chinese language websites you may have consented to data processing or accepted cookies which might lead to us processing your data even if you are located outside of China. On the other hand, we will target Chinese travelers when visiting Europe with advertising campaigns ran on behalf of our clients. You can change your preferences at any time and you can also exercise your rights by writing to

We rely upon consent as a legal basis for most data we process. Still we believe we have a legitimate interest to collect and process personal data for the following purposes:

  • Understanding whether users have made purchases after having seen ads.
  • Counting the number of times users who have seen ads have proceeded to buy a product or service to understand the overall return on investment of that ad.
  • Understanding browsing behaviors of aggregated users.
  • Ensuring ads are not shown to the same users more than a certain number of times.
  • Counting the number of times ads have been seen.
  • Counting the number of times ads seen have been clicked on to understand which creative formats generate interest and engagement.
  • Understanding if ads are seen by users to optimize advertising investment.
  • Checking for fraudulent behavior.

Business contacts data

If you are a business contact, a business partner, a client, an agency, a publisher, a data provider, a prospect etc., we may hold some personal data about you. We will need that data in order to communicate, invoice, manage contracts and products and services we offer to you. That data we have collected may take many forms, ie name, email address, billing address, office address, phone numbers, title, employer etc. We would only hold this information because you have shared that information with us; it may be because you are a client (and we had to invoice you, offer our services to you etc.) or you may be a prospect and we would have obtained that information from exchanging emails or business cards, or during meetings or events etc.

For European users:

Under the current law, we would not have to obtain consent in order to keep that data as we require this data in order to manage our contract with your organization, or the data processing is necessary for our legitimate interests in marketing our services or evaluating new services and supplies. You can exercise your data subjects’ rights of that personal data and contact us at

Our retention policy for this data is as follows, i.e. we will delete your data:

  • Three years after the last contact.

How do we use the data

We will process the above data and analyze your preference and interest, and display the advertisements that match your interest the most. We will also contact you, answer your inquiry, share with you the latest news of EternityX through email or other communication means, according to the contact information that you may have voluntarily provided.

We will use the collected data to make decisions or buy, track, or report on ads served via ad exchanges. We may also share performance data with advertisers or/and their agencies. During this process, we may overlay third-party data collected from third-party data providers to enhance our decision making. Data also helps our clients to serve ads more relevant to users, therefore enhancing the return on investment and making ads more meaningful. In compliance with the best industry standards, we also use IP addresses for purposes such as fraud detection to help alert us to situations which could not have been caused by human behavior, such as a massive amount of clicking in a limited period of time.

We do not process any information or combine with information obtained through third parties in order to determine the identity of users. We will also contact you, answer your inquiry, share with you the latest news of EternityX through email or other communication means, according to the contact information that you may have voluntarily provided.

For European users:

We provide data to other companies in our corporate group and technical service providers based outside the EU/EEA that require access to data in order to assist us in providing our services. In particular, we work with reputable external organizations (such as ad exchanges, measurement and verification services), to which we provide certain data which may include personal data, in order to provide our technology platform and services, on the basis of detailed written agreements requiring among other things compliance with applicable laws and security standards.

If any governmental body, law enforcement agency, or regulatory authority requested data from us, then we would normally comply with such request without having to notify you or other users.
