Privacy Policy

Musette holds your bodyweight, your workout metrics, and what you ate. That is health data, and this page states plainly what happens to it.

The short version: Your data is used solely to compute your fueling plan and shopping lists. It is never sold, and never shared for advertising or marketing. Three sub-processors process it on our behalf, named below. You can export or erase your data anytime with one tap.

What Data is Held

CategoryPurposeRetention Window
Bodyweight, height, age, sexCalculates resting metabolic rate (BMR) and carb targetsUntil account deletion
Workouts: hours, load, power, heart rateCalculates daily energy expenditure and recovery statusUntil account deletion
What you ate & checked offReconciles planned intake against actual consumption90 days (pruned automatically)
Passkey credentials (public key)Enables secure, passwordless authenticationUntil account deletion
intervals.icu API credentialsSyncs completed workoutsUntil you disconnect the integration

The 90-day retention limit on the food log is enforced by automated code in the sync engine — old items age out automatically.

Legal Basis (GDPR Article 9)

Bodyweight and physiological training load constitute special-category health data under Article 9 of the UK and EU GDPR. We rely on your explicit consent, provided during enrollment and recorded with a timestamp. You may withdraw consent at any time by deleting your account, which erases your stored record.
