Tracking and data privacy


When you implement tracking on the website or app or your advertiser, you will have to provide visitors a data privacy statement. This is because several cookies are used for tracking and in most countries, the usage of cookies requires visitor’s consent. This article provides you with a standard data privacy statement informing the visitors of your advertiser’s website. Furthermore, a brief script is added which allows visitors of your advertiser’s website to opt-out of tracking. A brief description on how visitors of mobile applications can deactivate any mobile in-app tracking is added as well.
