Opportunity
Many period tracker users want better predictions but also worry about sensitive health data. A privacy-first cycle app can compete by combining transparent predictions, on-device storage and user-controlled exports.

Solution(s)
Build local-first cycle tracking and explainable predictions; add symptom pattern reports; sell premium privacy features, clinician exports and education packs.
Background
Past enforcement actions and lawsuits around period-tracker data sharing have made privacy a core product differentiator. Better prediction alone is not enough; trust and data control are the opening.
