"If we were talking about health apps generally in the wider world, then what we found would not be surprising," said Kit Huckvale, a PhD student at Imperial College London, who co-wrote the study."If we were talking about health apps generally in the wider world, then what we found would not be surprising," said Kit Huckvale, a PhD student at Imperial College London, who co-wrote the study.
But given that the apps the study looked at were supposed to have been vetted and approved, finding that most of them did a poor job of protecting data was a surprise, he added.But given that the apps the study looked at were supposed to have been vetted and approved, finding that most of them did a poor job of protecting data was a surprise, he added.

Mr Huckvale and colleagues looked at 79 separate apps listed in the NHS library. Over six months they periodically supplied the apps with fake data to assess how they handled it.Mr Huckvale and colleagues looked at 79 separate apps listed in the NHS library.

More than half of the apps had a privacy policy but many of these were vaguely worded and did not let people know what types of data were being shared.More than half of the apps had a privacy policy but many of these were vaguely worded and did not let people know what types of data were being shared.
Mr Huckvale said the most of the data the apps gathered and shared was about a person's phone or their identity, with only a handful collecting information about the health of users.Mr Huckvale said the most of the data the apps gathered and shared was about a person's phone or their identity, with only a handful collecting information about the health of users.

Mr Huckvale added that the NHS needed to work harder on testing because of how apps were likely to be used in the future.Mr Huckvale added that the NHS needed to work harder on testing because of how apps were likely to be used in the future.
