UberMensch Privacy Policy

UberMensch Coach is a training and wellbeing coach made by David Weese (Mad Professors). It is built to work on your phone. We run no servers for it and receive none of your data. There are no accounts, no analytics, no advertising and no third-party tracking.

What the app reads

With your permission, UberMensch reads data from Apple Health (on Android, from Health Connect) to plan your training and answer your questions. That can include activity, steps and workouts; heart rate, heart rate variability, resting heart rate and heart rate recovery; sleep, breathing rate, blood oxygen and wrist temperature; blood pressure and blood glucose; weight, height and body fat; nutrition and water; mindful minutes; menstrual cycle; and your date of birth. You decide which of these to share, and you can change that at any time in the Health app or in your phone's settings.

UberMensch only reads health data. It never writes to Apple Health or Health Connect.

What the app stores, and where

• Your conversations with the coach
• Your goals, plans, strength log and check-ins
• The facts the coach remembers about you (visible and deletable in the app)
• A daily summary of your health values, so the coach can see trends
• Your in-app settings

All of this is stored only on your phone, in the app's private storage. Like other app data, it is included in your phone's backups if you make them. In Settings you can export everything or delete everything; deleting the app removes it as well.

Who answers your questions

You choose the coach's engine in Settings. What leaves your phone depends on that choice:

• This iPhone (iPhone only) uses Apple's on-device model. Nothing leaves your phone.
• Apple's cloud (iPhone only) sends your question and the coaching context (goals, plan, memories and a summary of your recent health values) to Apple's Private Cloud Compute to produce the answer. Apple states that this data is used only to answer the request, is not stored, and is not accessible to Apple.
• Open model runs a model on your phone. Nothing leaves your phone while it answers. The model itself is downloaded once, on your request, from Hugging Face: an ordinary file download that sends no information about you or your health. As with any download, Hugging Face sees your IP address.
• Server is optional and is only for people who run their own UberMensch server (see how to set one up). Before anything is sent, the app asks for your consent. Each question then sends your messages, memories, goals, plan, a summary of your recent days and today's values to the server address you entered. The server keeps a short history of daily values and passes the rest to the model provider its owner configured: Anthropic, OpenAI, or a model running on that machine. Raw health samples stay on your phone. The server is run by you, not by us; a model provider's handling of the data is governed by its own terms and privacy policy. You can switch back to an on-phone engine at any time.

Apple Watch

The Apple Watch app receives today's plan from your iPhone over Apple's Watch connection and sends back the sessions you mark as done. Nothing goes anywhere else.

Notifications

Reminders and check-ins are created on your phone. UberMensch does not use a push notification service.

How health data is used

Your health data is used only to coach you. It is never used for advertising, never sold and never shared with data brokers.

Not medical advice

UberMensch is not a medical device and does not diagnose or treat any condition. Talk to a professional about any health concern.

Children

UberMensch is not directed at children and does not knowingly collect personal data from anyone.
