Dive Brief: 

• Facebook has removed HasOffers and Kontagent from its mobile marketing partner program. 
• The two companies violated Facebook policy by holding onto user data for too long and not requiring advertisers to update their privacy policies to notify users of data collection. 
• App developers using HasOffers or Kontagent to track their app install campaigns on Facebook will no longer have access to the data. 

Dive Insight: 

Facebook is smart to keep a diligent watch on mobile marketing partners to ensure that they are in compliance with its terms of the agreement. The social giant certainly has an upper hand in the relationship, as it is the gatekeeper to the data. Cutting HasOffers and Kontagent will certainly send the message that Facebook is serious about its policies. 

UPDATE: Kontagent CEO issued additional commentary in response to Facebook's decision. The statement, which can be found here, describes in greater detail what Kontagent's actions were regarding data.
