UNDA — Intended Purpose

Status: Draft. This is UNDA's formal intended-purpose statement per §1. Reviewers: Must be reviewed by qualified EU/Spanish counsel before public launch. Last reviewed: 2026-08-08

Statement of intended purpose

UNDA is a fitness and training support product. It helps users understand their own menstrual cycle patterns and adapts training recommendations to the phase of the cycle, the user's recent training, their subjective energy and symptoms, and their historical individual response.

UNDA is not a medical device. It does not diagnose, prevent, monitor, predict, prognose, treat, or alleviate any disease. It does not replace a doctor, physiotherapist, or other qualified healthcare professional.

In scope

UNDA:

1. Lets users log period dates, symptoms, mood, and energy on the days they choose.
2. Computes an estimated cycle day and estimated cycle phase from the user's own logged data.
3. Recommends workouts from a library, taking cycle-phase estimates as one input alongside training history, subjective energy, and user goals.
4. Lets users mark workouts as completed and record how the workout felt.
5. Shows users patterns in their own historical data (symptoms per phase, sessions per phase, felt-score averages per phase).
6. Optionally imports fitness activities from Strava, Intervals.icu, Garmin, Apple HealthKit, or Google Health Connect to individualise the plan.
7. Optionally syncs the user's data across their own devices via Supabase (EU region).

Explicitly out of scope

UNDA does not, and must not be marketed to:

• diagnose PCOS, endometriosis, amenorrhoea, hormonal imbalance, or any other condition;
• detect disease or reproductive disorders of any kind;
• treat PMS or any medical condition;
• prevent RED-S, injury, or any disease/disorder;
• measure the user's actual hormone levels;
• determine whether exercise is medically safe or unsafe on a given day;
• replace a doctor, physiotherapist, dietitian, coach, or any other qualified professional;
• provide clinical decision support;
• prescribe treatment.

Where UNDA sits in the user's care

UNDA is a personal tool. It has no clinical role. Users can and should consult qualified healthcare professionals for any medical question.

Users

• Primary user: healthy adult women (18+) who train regularly.
• Excluded from v1: users under 18 (see §16); pregnant users (out of scope); users with clinical conditions where training decisions should be made with medical guidance (UNDA does not know this, so the copy defers to the user's own judgement and their care team).

Language & positioning rules

Approved (§1.1):

• "Training that moves with your cycle's rhythm."
• "Training adapted to your cycle, recovery and individual response."
• "Understand patterns between your cycle and training."
• "A training recommendation informed by your recent recovery and cycle pattern."
• "Consider reducing intensity today if the session does not feel right."

Prohibited without separate medical-device review (§1.2): any language that positions UNDA as diagnosing, preventing, monitoring, predicting, prognosing, treating, or alleviating a condition.

Regulatory trigger

Per §1.3, if any planned feature moves from fitness/personalisation into diagnosis/prevention/monitoring/prediction/prognosis/treatment or alleviation of disease, work on that feature stops until a medical-device regulatory assessment is completed.

Examples of features that would trigger this review:

• Auto-detection of "abnormal" cycles → stop.
• "You may have PCOS" or similar → stop.
• Predicting fertility windows for conception → stop and reassess.
• Any RED-S warning system → stop.
• Advising on medication timing → stop.

Changes to this document

Any material change to the intended purpose requires: (a) product owner sign-off, (b) legal review, and (c) an updated claims register (§19).
