Health apps pose ‘unprecedented’ privacy risks
Using popular health apps could mean private information about medical conditions is not kept confidential, researchers warn.
Of 24 health apps in the BMJ study, 19 shared user data with companies, including Facebook, Google and Amazon.
It warns this could then be passed on to other organisations such as credit agencies or used to target advertising.
And data was shared despite developers often claiming they did not collect personally identifiable information.
