Personal Data Protection and the Privacy Policies of Health and Lifestyle Apps


As a new dad to a healthy and very curious 6 month-old, I live in a constant state of anxiety. The latest of which is that my baby girl’s first spoken word just might end up being “Alexa”, instead of “Mama” or even “Papa”. Technology has indeed crept into our daily lives as natural as breathing air. The convenience of modern technology offers the promise of instant information, entertainment, and connection through voice command or a single tap. Yet through all of these manna from above, sacrifices had been made, at times without our knowledge or consent, to things we hold private.

This study focuses on the state of privacy policies of popular medical and lifestyle apps[i] available in Japan. Imbued with the capability to measure active body movements both during rest (sleeping) and in motion (running), track location, collect activity and search histories, analyze nutritional intakes, monitor heart rates, record sensitive medical conditions, capture images, and even dispense health recommendations.

In the new age of data, the ability and usefulness of using smartphones to benefit our health and fitness should be balanced with valid privacy concerns of the end-users. How could an owner of the latest iPhone or Galaxy smartphone ensure that his or her legal right to privacy will be respected? No other object has captured our data as much as the smartphone through the apps that we ourselves choose to install.

[i] Application programs, further limited to smartphone application programs for the purposes of this study.
