THE privacy reference for menstrual tracking in 2026. Since the Flo saga (FTC 2021 + $56M class action in 2025), the positioning gap is enormous.

ADHD relevance: women with ADHD overwhelmingly report symptom variations across the hormonal cycle. Cross-referencing Clue with an ADHD tracker can reveal things like “the days my executive function collapses = 3-5 days before my period”. Potentially life-changing.

A natural companion for an ADHD app partially aimed at women.
