CoachSage

Privacy Policy

Last updated: 22 June 2026

CoachSage ("the app", "we") is an AI training coach for endurance athletes. This policy explains what data the app accesses, how it is used, and the control you have over it. We have designed CoachSage to keep your data on your device wherever possible.

      In short: Your health and training data stays on your iPhone. When you ask for coaching, the relevant context is sent securely to our coaching service and our AI provider purely to generate your plan or reply — it is not stored on our servers, sold, or used for advertising.
    

Health and fitness data we access

With your explicit permission, CoachSage reads the following from Apple Health (HealthKit) to assess your recovery and build your training plans:

Heart rate variability (HRV) and resting heart rate
Sleep analysis
Workouts (runs, rides, swims and other activities), including distance, duration, heart rate, and — for cycling — power and cadence
Step count

This data is read on demand and processed on your device. CoachSage does not write to Apple Health unless a future feature explicitly asks you to.

Information you provide

You may enter goals (such as a target event and date), training-day preferences, your post-workout effort ratings, and notes for your coach. This is stored locally on your device.

How your data is used

To generate your daily guidance, weekly plan and goal plan, the app sends a summary of the relevant health and training context, along with your goals and preferences, to:

Our coaching service — a stateless backend that forwards your request to our AI provider and returns the result. It does not maintain a database of your health data; the information is used only to process that request.
Anthropic, our AI provider, whose Claude models generate the coaching text. Data sent through Anthropic's API is used only to produce your response and, per Anthropic's policy, is not used to train their models.

We do not sell your data, use it for advertising, or share it with any other third parties. CoachSage contains no third-party advertising or analytics tracking.

Where your data is stored

Your plans, goals, preferences and effort ratings are stored locally on your device. Your coaching access key is stored in the iOS Keychain. Health data read from Apple Health is not retained on our servers after a request is processed.

Your control and choices

You can review or revoke CoachSage's access to any Health data type at any time in the Health app → Profile → Privacy → Apps → CoachSage.
You can choose which device's HRV is used for recovery in the app's Settings.
Deleting the app removes the data stored locally on your device.

Children

CoachSage is not directed at children and is intended for users aged 16 and over.

Changes to this policy

We may update this policy as the app evolves. Material changes will be reflected here with a new "last updated" date.
