# FemTech Design Guide

The FemTech market is projected to reach \$100 billion, yet women's health has been historically underserved by technology. Building products women trust requires understanding the unique privacy, clinical, and design considerations in this space.

## Privacy-by-Design for Sensitive Health Data

Women's health data is uniquely sensitive — it can reveal pregnancy status, fertility intentions, and reproductive health decisions. Privacy must be foundational:

* **Data minimization**: Collect only what's clinically necessary
* **Granular consent**: Separate consent for different data uses (cycle tracking, research, sharing with providers)
* **Anonymization**: Options for anonymous participation in research
* **No data selling**: Clear policies against selling health data

## Cycle Tracking UX Patterns

The most common FemTech feature requires thoughtful design:

* **Prediction vs. confirmation**: Track confirmed data vs. predicted dates
* **Symptom logging**: Flexible, customizable symptom categories
* **Fertile window**: Clear communication of prediction uncertainty
* **Pregnancy mode**: Transitions from tracking to pregnancy support

## Fertility and Pregnancy Journey Design

Design for the emotional complexity of fertility:

* **Sensitive language**: Avoid assumptions about family-building goals
* **Loss and disappointment**: Design for cycles that don't result in pregnancy
* **Medical integration**: Connect fertility data to clinical care
* **Partner/caregiver features**: Shared access with appropriate privacy controls

## Addressing Historical Distrust

Women have reasons to be skeptical of health technology:

* **Transparency**: Open about data practices and clinical evidence
* **Clinical validation**: Invest in research that validates your approach
* **Community input**: Involve users in product decisions
* **Diverse representation**: Ensure design and testing includes diverse populations
