How is my Muscle-Loss Risk Score calculated? From your quiz answers (age, weight trajectory, medication, weeks on it, training habits), anchored to published research on lean-mass loss during GLP-1 treatment (STEP-1 lean-mass substudy). It's an educational estimate, not a diagnosis.
Do my photos get uploaded? No. Weekly check-in photos are stored only on your device and are deleted when you delete the app.
What does the AI coaching send? Only the day's numbers (protein, training, shot day, appetite, local hour) — never your name, photos, or anything identifying. You can switch to built-in coaching any time in Settings → AI coaching.
How do I cancel my subscription? Settings app → your Apple ID → Subscriptions → Lean → Cancel. Deleting the app does not cancel a subscription.
How do I turn reminders on or off? Lean → Settings → Reminders. Each reminder (shot-day morning, evening protein check, weekly check-in) has its own toggle.
Can Lean tell me what dose to take, or when to stop my medication? No. Lean never gives medication or dosing advice. Those decisions belong to you and your prescriber.
