Marketing Platform Privacy Notice

Last updated: 1 September 2020




Crossover Consulting Limited (Crossover) is a marketing company that helps organisations to deliver more relevant communications to consumers.


Crossover is registered with the ICO under the Data Protection Act, with registration number ZA700092


This policy applies to Crossover Consulting Limited, it’s subsidiaries and affiliates (referred to as ‘we’, ‘our’ or us). 


We are committed to maintaining the highest standards of privacy compliance including compliance with the GDPR. This notice explains the nature of the personal data that we process and the associated rights of consumers.




Our marketing products rely on various forms of data collected from apps that are installed on user’s mobile devices as well as websites that have been visited.


This includes:

Precise and relative location data

Unique device identifiers known as ‘Mobile Advertising ID’s’ 

Time and date information

IP addresses

Partner audience segments (i.e. interest profiles based on location and app/website usage)


In doing so, we do not collect any Personally Identifiable Information such as name, email address, telephone number etc.


We do not collect or process any ‘special category data’ as defined by the GDPR, for example personal data that relates to ethnicity, religion, political opinions, health, sexual orientation etc.


Nor do we knowingly collect data from those aged under 16.




The data described in this policy is used for the following purposes:


Creating ‘interest-based audience segments’ - this allows us to serve more relevant advertising to particular devices.


Measuring marketing effectiveness - we analyse aggregated groups of users who have been served particular messages to understand whether overall behaviours have changed.


Creating traffic based insights such as store catchment area analysis or aggregated store visitation patterns.


These purposes may involve combining and/or matching data with other sources where legally permissible.


We do not sell personal data to third parties.



We receive data from third parties on the contractual basis that data has been lawfully obtained and that the device user has granted consent for such data to be transmitted to Crossover. Such partners are responsible for obtaining all applicable consents from device users.


Our lawful basis for processing the above data is consent and Crossover acts as a data controller.


You have the right to withdraw your consent at any time. Please see sections titled ‘Data Protection Rights’ and ‘Opting Out’ for further details.




We disclose data to affiliate and third party service providers who provide data processing services to Crossover, for example cloud storage providers or platforms that we use to serve ads including Google, Facebook, Snap, Twitter, TikTok and Pinterest. We may also disclose data to those who otherwise process personal information for purposes that are described in this Privacy Policy or are notified to device users when personal information is collected. 


We may also disclose data if required by law or a valid and effective subpoena.




We store data in the United Kingdom and the European Union. If personal data is transferred outside of the EEA or Switzerland such transfers are safeguarded by European Standard Contractual Clauses and Data Processing Agreements where this is required by European Data Protection Law.


Data is stored in Amazon Web Services and Google Cloud Platform and we adhere to generally accepted industry security standards during transmission and once it is received.


We retain personal data for as long as necessary to provide our Services or for legal and contractual purposes. Ordinarily, Mobile Advertising IDs will only be stored for 12 months from the date on which we received such data. After this date, ID’s may be hashed and de-identified.
