Microsoft How Old do I Look app

How Old do I Look was an app developed and released by Microsoft that enabled people to upload their own images, or those of anyone discovered on Microsoft's search engine Bing, to be analysed for their age and gender. 

Designed to site to showcase Microsoft's cloud server software, the app drew on the company's Face API to analyse twenty-seven 'facial landmarks' using statistical algorithms.

Accuracy

The app reputedly drew 240 million pictures from 33 million users in four days, but views on the app's accuracy were mixed, with some people reporting is was uncannily accurate, and others lamenting it was 'terrible' and a 'flop'.

Privacy

Microsoft promised not to retain users' pictures. However, privacy experts expressed their concerned that Microsoft's general cloud services agreement contradicted what it said on the app by stating the company could copy, edit and distribute any uploaded pictures for use with their internet services.
