Approximately 75% of the top 100 free mobile apps are tracking user data without explicit consent, as revealed by a study from Tenscope. The most invasive app is Facebook Messenger, scoring 100 out of 100 for invasiveness, collecting over 20 times the data compared to more privacy-conscious apps. Lyft ranks third in terms of data privacy concerns. The study also identified common deceptive design patterns that pressure users into granting excessive permissions, such as 'All or Nothing' consent and complex privacy settings. The 10 most private apps include TeaOnHer, ParentSquare, and Microsoft Edge, which demonstrate that robust functionality can be achieved with minimal data collection.
