Privacy issues shadow medical apps’ claims to improve care
The technology could revolutionize health care by encouraging consumers to be more involved in their health. But most apps aren’t subject to federal laws that safeguard medical information.

WASHINGTON — Smartphones and tablets are go-to gadgets to count calories, document daily jogs, measure heart rates and record sleep patterns. Some applications even analyze blood-sugar levels, track fertility or monitor moods for signs of depression.
Inexpensive and easy to use, mobile medical apps are also booming business: more than 97,000 varieties are available. By 2017, the mobile industry tracker Research2Guidance predicts, the market will grow to $26 billion.
By then, the firm estimates, half the world’s more than 3.4 billion smartphone users will have downloaded health apps.
The technology could revolutionize health care by encouraging consumers to be more involved in their own fitness and by making medical technology more ubiquitous, portable and cheap. Increasingly, it could bring high-tech help to populations with little access to physician care.
But not all apps deliver the medical miracles they promise. And most aren’t subject to federal laws that safeguard medical information. So consumers need to be wary.
“People who are using these health and fitness devices ... record a tremendous amount of truthful and very sensitive information about their bodies and behaviors with companies that they know very little about,” said Heather Patterson, a postdoctoral scholar at New York University’s Information Law Institute.
Consumers log everything from diet to sexual activity to tap all the features an app offers, she said.
“They want to get accurate feedback about their sleep quality and the exercise they’re getting and make a decision about that muffin they’re thinking about eating,” Patterson said.
They may not realize how the companies that collect that information are using it or know whether it’s stored securely, Patterson said.
The Health Insurance Portability and Accountability Act, which Congress passed in 1996, limits who can look at and receive your medical information. That means doctors, insurers and pharmacies must keep your records confidential, unless you explicitly give them permission to share them.
The developers of health apps don’t necessarily have the same obligation.
A study published in July found that many medical apps don’t encrypt the sensitive data that consumers input about their health.
Apps frequently share that data with advertisers and other third parties without users’ knowledge. Of the free apps reviewed in the study, less than half posted privacy policies, and only half of those that did described the apps’ technical processes accurately.
Often data was sent unencrypted, Givens said. One app shared users’ locations and other personal information with 10 other companies within three seconds of being turned on, she said.
Unwitting consumers may be opening themselves to insurance or employment discrimination, identity theft, or targeted advertising that references their personal struggles with infertility, depression or incontinence.
Paid apps in the study tended to pose lower risks because they rely less on ads to make money.
Consumers also should assume that any information they do share may be sent to the app developer, as well as third-party sites, data-mining companies and marketers, Givens said.
Givens and other consumer advocates want federal regulators to step in and set stricter rules to regulate the safety and security of medical apps.
The Food and Drug Administration proposed guidelines in 2011 that would apply to apps that meet the agency’s definition of medical devices or are used as accessories to medical devices. The guidelines have yet to be finalized.
More scrutiny will come as laws catch up with the technology, said Dr. Nicholas Genes, an emergency-room physician and assistant professor at the Icahn School of Medicine at Mount Sinai.
Many of the apps created recently could be game changers for the medical profession, especially in remote areas that have poor access to modern health-care facilities, Genes said.
“In the developing world this can be a real boon, because everyone has (cell)phones, but they may not have money for expensive equipment,” he said.
