Apps that deal with some of the most sensitive and personal data, such as that concerning a user’s mental health or religious activities, are said to rank among the worst privacy offenders.
This is the conclusion of a study conducted by the Mozilla Foundation, which singled out mental health and prayer apps as being prone to track and collect data revealing a person’s state of mind, feelings, and thoughts, and then “share” that for-profit via targeted advertising.
Mozilla’s team looked into 32 apps from this category, putting a “privacy not included” label on 29, and publishing the findings in a guide of the same name. 25 of these apps didn’t pass the foundations’ minimum security standards around password quality and handling of security updates.
PTSD Coach, developed by the US The Department of Veterans Affairs, has “strong privacy policies and security practices,” while chatbot Wysa “seems to value users’ privacy.” And the Catholic prayer app Hallow was the only one to “respond in a timely manner” to Mozilla’s emails.
Besides these technical issues, the apps singled out in the report are also said to target “vulnerable users with personalized advertisements” and track and share biometric data.
