Medical and Health Disclaimer

1. In an emergency

MHE is not an emergency service, and nobody watches your entries for you. If you think you or someone else needs urgent medical help, call 112 or 999 now.

Call at once if you have chest pain, a severe headache, changes to your vision, sudden weakness or numbness, trouble breathing or speaking, or you faint. Do not wait for your doctor or for a reply from us.

2. Education, not medical advice

Everything in the app, including programs, plans, targets, recipes, reports and messages, is general education about nutrition, exercise, hydration, sleep and stress. It is not medical advice, diagnosis or treatment, and it does not replace a doctor, pharmacist, dietitian, midwife or other professional who knows you.

If anything in the app conflicts with your doctor's advice, follow your doctor. Never delay or ignore medical advice because of something in the app.

Our content reflects the evidence we reviewed when we wrote it, and science moves on. Results differ from person to person, and we do not promise any particular result.

3. What the app is for

MHE is a lifestyle and education tool. It is not intended to diagnose, treat, cure or prevent any disease, or to manage a condition in place of your care team. We have not certified or registered it as a medical device. Programs about health markers such as blood sugar or blood pressure help you build habits and keep a record of readings you type in. They do not tell you whether you have a condition, and they do not change any treatment.

4. How your plan is built

No clinician assesses you through the app. The app builds your plan with fixed rules from the details you enter, and its calorie, nutrition, exercise and step figures are estimates that can be wrong for you. If a target feels wrong for your body, stop and check with a professional.

5. Before you start

Talk to your doctor before you start a program or change how you eat, fast or exercise, especially if you:

• have a long-term condition, such as heart disease, high blood pressure, diabetes, kidney or liver disease
• take any prescribed medicine
• are pregnant, trying for a baby or breastfeeding
• have, or have had, an eating disorder
• are very overweight or underweight
• feel chest pain, faintness or breathlessness when you are active, or have been told to limit exercise.

6. Our safety precautions

The app takes reasonable precautions based on the details you give us. Depending on your age, body measurements, pregnancy, conditions and medicines, it may close or limit programs, calorie deficits or fasting for you, and it shows prompts to see your doctor. When it closes something, it tells you on the screen.

These precautions have limits:

• They work only on what you tell us. Keep your details accurate and up to date. If you leave something out, or enter a medicine or condition the app does not recognise, it cannot take that into account.
• They can miss things. No warning does not mean a plan or a reading is safe for you.
• If you update your health details, the app tells you when your plan no longer fits, and you need to rebuild it.
• They do not replace your doctor. If the app closes something to you, do not work around it.

Pregnancy and breastfeeding. No program adjusts calorie targets for pregnancy or breastfeeding, so any target is likely to be too low for you. Take any calorie target to your midwife or GP before you follow it.

7. Medicines

Never start, stop or change a medicine or its dose because of the app. Only your prescriber can do that. Changes to your diet, weight, fasting or exercise can change how some medicines work, including diabetes medicines (such as insulin, SGLT2 inhibitors and GLP-1 medicines) and blood pressure medicines. Agree your plan with your prescriber before you start. With insulin or sulfonylureas, eating fewer carbs, fasting or a calorie deficit can cause a dangerous low blood sugar (a hypo). With blood pressure medicines, weight loss and less salt can push your pressure too low.

If you take an SGLT2 inhibitor and feel sick, vomit, have stomach pain, breathe fast or feel unusually tired or confused, get urgent medical help, even if your blood sugar looks normal.

8. Readings and health prompts

Any reading you type in, such as blood pressure, blood test results or ketones, is for your own record. A message about a reading is a prompt to act, not a diagnosis, and one reading cannot diagnose anything. The app does not check every reading for danger, including blood sugar, cholesterol and ketone readings. It does not send your readings to a doctor, and it does not alert anyone. If a reading worries you, or you feel unwell, act on it yourself and trust your symptoms over the app. Questionnaires in the app are simple self-checks, not a diagnosis of any condition.

9. Food, exercise and supplements

Nutrition values are estimates. Check every food label and ingredient against your allergies, intolerances and any medical diet. If your care team limits your fluids, follow their limit, not the app's hydration guidance.

Exercise carries a risk of injury and, rarely, of a heart problem. Start at a level that suits you and build up in small steps. Stop at once and get medical help if you feel chest pain, faintness, unusual breathlessness or a racing or irregular heartbeat.

Information about supplements is general education, not a recommendation to take anything. Supplements can interact with medicines and conditions, so check with a pharmacist or your doctor first.

10. Eating disorders

Tracking food, weight and calories can be harmful if you have, or have had, an eating disorder. Use the app only with your treatment team's agreement, and stop if it makes things harder. If tracking makes you anxious, or you find yourself skipping meals or making up for what you ate, stop using the tracking features and talk to your GP.

Help is available from Bodywhys in Ireland (01 2107906) and Beat in the UK (0808 801 0677). If you feel you cannot cope, call Samaritans on 116 123 in Ireland and the UK, or call 112 or 999.

11. Our responsibility to you

We take care to make the app's content and precautions work as this disclaimer describes. If you think something went wrong, stop following that part of your plan and tell us at support@myhealthengineer.com.

Nothing in this disclaimer excludes or limits our responsibility for death or personal injury caused by anything we do or fail to do, for fraud, or for anything else the law does not let us limit. Nothing in it affects your legal rights as a consumer. Our Terms of Service (section 7) set out the rest of our responsibilities.

12. Changes and contact

We update this disclaimer when the app or the evidence changes. When a change matters, we email you in good time before it applies, and the app asks you to accept it. A change we need to make for your safety may apply sooner. Terms section 6.1 explains your rights when we make a change. Questions: support@myhealthengineer.com. For anything urgent, use section 1.
