Health & safety
Effective 5 August 2026 · Saaf for iPhone
Saaf is a wellness app, not a medical device. It does not diagnose, treat or prevent any condition, and it never claims to detect illness.
WHAT THE LANGUAGE MEANS
Saaf says "may indicate", "trending", and "below your baseline" because that is the strength of the evidence a consumer wearable can provide. A body-signal flag means your resting heart rate, heart-rate variability or wrist temperature differs from YOUR OWN recent baseline. It is not a diagnosis and it does not mean you are ill.
WHEN TO SEEK HELP INSTEAD
Chest pain, breathlessness at rest, fainting, an irregular heartbeat that worries you, a fever you cannot explain, an injury, or any symptom that is new and severe — contact a medical professional or emergency services. Do not wait to see what a score does tomorrow.
TRAINING SAFETY
Workout plans are generated from the profile you enter. They cannot see your injuries, your joints, your medication or your medical history. Warm up, use a load you can control, stop if something hurts in a way that is not muscular effort, and get clearance from a professional before starting a new programme if you have a heart condition, are pregnant, are recovering from injury or surgery, or have been inactive for a long time. The same applies outdoors: Running Mode measures a run, it does not judge whether you should be on that road at that pace. Watch the traffic, not the phone.
THE COACH
The Coach is a wellness feature, not a clinician. It explains numbers Saaf already computed and general concepts from a reviewed reference library; it does not examine you, it cannot see anything you have not given it, and it will not tell you what a symptom means, whether to take a medication, or how to manage a diagnosed condition. When a question reaches any of those, it stops and points you to a professional instead of answering — that refusal is the feature working, not failing. Nothing it says is medical advice.
WHAT THE FOOD SCANNER IS
A photograph gives an ESTIMATE of what is on the plate, with a range around it, and the range is part of the answer rather than decoration. It is not a measurement of what you ate. Calorie and macro figures from a scan, from the catalogue, or from a target Saaf derived are all estimates; if a medical or clinical reason means your intake has to be accurate, do not rely on them.
PREGNANCY AND MEDICAL CONDITIONS
Saaf's baselines, targets and scores are not validated for pregnancy, for people managing a chronic condition, or for anyone whose physiology a general population model does not describe. Treat every number as informational in those situations.
ACCURACY
Every score is only as good as the data underneath it. Missing sleep tracking, a phone left on a desk, or a scale that writes an estimated body-fat percentage all change the answer. Saaf shows which inputs it used and how confident it is; read those before you act on a number.
