My Body, Their Business: User Perspectives on Commercial Data Practices in FemTech mHealth Apps

Key findings from this study

This research indicates that:

• Users differentiate sharply among data types, resisting peripheral data collection while accepting data use more readily when functionally necessary for app features.
• Interface prototypes with exaggerated transparency elicited more forgiving user responses to commercial practices compared to text-only vignette descriptions of identical practices.
• Commercial data use was judged conditionally—participants tolerated commercial practices primarily when aligned with stated health functionality.

Overview

FemTech applications for fertility, menstruation, and menopause management increasingly collect sensitive health data through opaque commercial models. This study examined how 187 survey participants perceived and negotiated data collection and commercial use practices within these apps, using factorial vignettes and interface prototypes designed to elicit reflection on user boundaries and discomfort.

Methods and approach

An online survey combined factorial vignettes with provotypes—interface prototypes engineered to provoke critical reflection. Participants evaluated data collection and commercial practices across multiple scenarios. Provotypes presented exaggerated transparency conditions, while vignette conditions used brief text descriptions. The dual-method design enabled comparison of user responses to varying presentation modes.

Results

Participants exhibited differentiated responses across data types, resisting peripheral data collection and pervasive tracking mechanisms. Commercial practices received conditional acceptance, tolerated primarily when functionally relevant to app core functionality. Notably, provotypes elicited more forgiving responses to commercial practices than vignette-based text descriptions achieved, suggesting interface design and transparency presentation substantially influenced user judgment.

Participants drew sharp distinctions between data categories, distinguishing necessary from unnecessary collection. Tracking behaviors perceived as tangential to stated health purposes generated stronger resistance. When commercial use aligned with functional necessity, tolerance increased measurably. The gap between provotype and vignette responses indicates that presentation modality affects user perception of identical commercial practices.

Implications

Interface design emerges as a consequential factor in how users perceive commercial data practices, warranting consideration in FemTech development beyond textual privacy disclosures alone. Enhanced transparency through visual interface design may increase user acceptance, though this mechanism requires careful calibration to avoid obscuring underlying commercial practices through design choice. FemTech developers must align commercial data collection with demonstrated functional relevance to core health features.

The conditional acceptance pattern suggests user-developer alignment improves when commercial practices serve explicit health or feature purposes. Developers designing FemTech applications should establish clear functional boundaries for data collection and justify commercial practices within those boundaries. Future FemTech governance frameworks should mandate transparency approaches that combine textual clarity with interface-level visibility rather than relying solely on traditional privacy documentation.
