AggregateIQ (AIQ) was accused of processing people’s data “for purposes which they would not have expected”.
The firm has appealed against the notice, which was issued by the UK’s Information Commissioner’s Office. Law firm Mishcon de Reya said the notice was “significant”.
If the company fails to appeal to the ICO’s notice or does not comply with it, it could face a large fine. The Information Commissioner’s Office confirmed the story to the BBC.
AIQ is a small Canadian data firm that uses data to target online ads at voters during public polls.
