How can Google offer this service for free?
We believe that all users deserve free, fast and sanitary online access. To offset the cost of providing the TiSP service, we use information gathered by discreet DNA sequencing of your personal bodily output to display online ads that are contextually relevant to your culinary preferences, current health status and likelihood of developing particular medical conditions going forward. Google also offers premium levels of service for a monthly fee (see below).
Note: We take your privacy very seriously. So we treat all TiSP users' waste-related personal information with tremendous discretion, in accordance with our Privacy Policy.
