Core Insights - Campus running apps are facing significant backlash from university students due to excessive advertisements and intrusive permissions required for usage [1][2][3] Group 1: App Functionality and User Experience - Campus running apps like Yundong Shijie, Budao Le Pao, and Shandong Campus have become essential tools for tracking students' physical activities, but they have transformed into platforms primarily focused on advertising revenue [2][3][4] - Students are required to download these apps to record their exercise, which has become a mandatory part of their physical education curriculum [3][4] - The apps often require multiple permissions, including accessibility features, which are claimed to be necessary for tracking exercise but are also used to push advertisements [10][11][12] Group 2: Advertising Revenue Model - The revenue model for these apps relies heavily on advertising clicks and user engagement, with each interaction generating income for the app developers [13][16] - The apps have been reported to use at least 20 different advertising SDKs, indicating a robust advertising strategy that capitalizes on user attention [11][12] - The cost for universities to implement these apps is relatively low, with contracts often ranging from 1.6 million to 7 million yuan, suggesting a high-profit margin primarily derived from student engagement rather than direct service costs [15][16] Group 3: Privacy Concerns and Regulatory Issues - The use of high-sensitivity permissions, particularly accessibility features, raises significant privacy concerns as they allow the apps to perform actions without user consent [12][20] - Legal experts have pointed out that the bundling of permissions and the forced consent for non-essential data collection may violate privacy laws [19][20] - There is an ongoing debate about the ethical implications of using accessibility features for commercial purposes, with potential regulatory scrutiny on the practices of these campus running apps [19][20]
