Mobile apps may collect, share, and analyze data from users. Although users can choose to decline apps' data collection behaviors through mobile permission systems or in-app settings, it is challenging and time-consuming for users to manually discover and correctly configure all the privacy settings for apps on their mobile phones. This issue also occurs in IoT apps, where users need to configure each device separately. Although they can manage some settings with platform apps (like Apple Home), many IoT devices expose device-specific settings within a device-specific app. In this position paper, we propose the PrivacyProfile, a framework that allows users to easily set their global privacy preferences and apply them to apps automatically. Users can indicate whether each of their privacy-related information can be collected, shared, and analyzed in their profile. Compatible apps then read the privacy profile and automatically configure their settings for users, e.g., enabling data collection behaviors or disabling data sharing. This design enables users to easily configure their privacy preferences once, rather than having to manually open each app and locate the corresponding privacy settings.
