1. Purpose and overview of this privacy notice

This privacy notice provides information about how Crimtan Holdings Limited a company registered in England & Wales under company number 07810698 (Crimtan, we, us or our) collects and processes data in connection with advertising services.

We provide services that allow online advertisers contracted to members of the Crimtan Group (our advertiser clients) to deliver relevant advertising more accurately.  We believe internet users benefit by encountering advertising that is more relevant to their perceived interests – we call this Relevant Advertising.

The Crimtan Group is made up of different legal entities:

  • Crimtan Holdings Limited
  • Crimson Tangerine Limited
  • Crimtan CEE Limited
  • Crimtan Technology Limited
  • Crimtan Polska SP Zoo
  • Scene Stealer Limited
  • Crimtan AU PTY
  • Crimtan MENA FZ LLC
  • Crimtan Singapore PTE Limited
  • Crimtan Japan KK
  • Crimtech LLC

2. The data we store and use

We attribute an identifier to your browser or device (an ID).  This identifier is not associated with any data that identifies anything other than your browser or device.

Once you consent to Relevant Advertising, when you visit the sites of our advertiser clients or sites where we serve online advertising, we associate what we learn about your visit with the ID. Here is how this works:

  • You visit site, consent to Relevant Advertising and we set up an ID in your browser
  • We track some aspects of how this ID behaves
  • We deliver more relevant advertising to that ID

Where you have consented to Relevant Advertising, we may collect, use and store different kinds of data against the ID (we refer to this as ID-related Data) which we have grouped together as follows:

Technical Data which includes:

  • internet protocol (IP) address
  • browser type and version
  • time zone setting and location
  • browser plug-in types and versions
  • operating system

Profile Data which includes the perceived interests associated with the ID.

Usage Data which includes:

  • web pages which have been viewed and the date and time of viewing
  • location
  • domain type
  • responses to an advertisement delivered by us for our advertiser clients

Consent to Relevant Advertising which includes the preferences you communicate to us.

We also collect, use and share Aggregated Data such as statistical or demographic data for any purpose. Aggregated Data may be derived from ID-related Data but is not associated with an ID, and thus is not treated as personal data in law. For example, we may aggregate your Usage Data with Usage Data associated with other IDs to calculate the percentage of users accessing a specific website feature. However, if we combine or connect Aggregated Data with ID-related Data, we treat the combined data as personal data which will be used in accordance with this privacy notice.

We do not collect any Special Categories of Personal Data against an ID (this includes details about your race or ethnicity, religious or philosophical beliefs, sex life, sexual orientation, political opinions, trade union membership, information about your health and genetic and biometric data). Nor do we collect any information about criminal convictions and offences.

3. How is ID-related data collected?

We use different methods to collect ID-related Data including through:

  • Direct interactions. This includes your consent to Relevant Advertising when you register your consents/non-consents which we associate with the ID.
  • Automated technologies or interactions. Once you have consented to Relevant Advertising, then as the ID interacts with websites containing our cookies and pixels, we may automatically collect Technical Data and Usage Data and associate it with the ID.

Please see our cookie information page for further details.

Third parties or publicly available sources.  We may receive data on the perceived characteristics and interests that we associate with the ID from various sources providing data based on location and category-based interests.

4. How we use ID-related data

In line with the requirements of the law, we generally rely on your consent as the legal basis for collecting and processing ID-related Data.

  • Request correction of ID-related Data that we hold about you. This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.
  • Request erasure of ID-related Data. This enables you to ask us to delete ID-related Data where there is no good reason for us continuing to process it. You also have the right to ask us to delete ID-related Data where you have successfully exercised your right to object to processing (see below), where we may have processed your information unlawfully or where we are required to erase ID-related Data to comply with a legal or regulatory obligation. Note, however, that we may not always be able to comply with your request of erasure for specific legal reasons which will be notified to you, if applicable, at the time of your request.

What we may need from you

We may need to request specific information from you to help us confirm your identity and ensure your right to access the relevant ID-related Data (or to exercise any of your other legal rights). This is a security measure we take to help avoid ID-related Data being disclosed to a person who has no right to receive it.
