Last updated: April 12, 2026

Overview

Coach Max ("we", "our", "the app") is an AI-powered running coach app. We take your privacy seriously and only collect data necessary to provide personalized coaching.

Data We Collect

Account information: Email address and name (for authentication)
Health data: Heart rate, HRV, sleep, steps, workouts, and running metrics from Apple Health (only with your explicit permission)
Training data: Your training plans, race goals, and coaching conversations
Device information: App version and basic device type for support purposes

How We Use Your Data

To provide personalized AI coaching and training plans
To analyze your health and workout data for coaching recommendations
To sync your training progress across sessions
To improve our coaching algorithms

Data Storage

Your data is stored securely on Supabase (PostgreSQL) with row-level security. Health data from Apple Health is processed on our servers to generate coaching insights but is not sold or shared with third parties.

Third-Party Services

Supabase: Authentication and database
Anthropic (Claude API): AI coaching responses (your conversations are sent to generate coaching advice)
RevenueCat: Subscription management
PostHog: Anonymous usage analytics
Strava/Garmin: Workout sync (only if you connect these services)

Apple Health Data

We request access to Apple Health data (heart rate, HRV, sleep, workouts) solely for coaching purposes. This data is never sold, shared with advertisers, or used for purposes other than providing you with personalized training advice. You can revoke access at any time in iOS Settings.

Calendar Access

With your permission, Coach Max reads the next 7 days of your calendar events so the AI coach can suggest realistic run times that don't clash with your schedule. Event titles and times are sent to our backend only to generate the current coaching response and are not stored. You can revoke Calendar access at any time in iOS Settings → Coach Max → Calendar.

Location

Coach Max uses your approximate location (city level) to fetch local weather and reference local running context when you chat with the coach. Location data is not stored or shared with third parties.

Data Deletion

You can request deletion of all your data by contacting us at yilmaz.koeknarx@gmail.com. We will delete your account and all associated data within 30 days.

Children's Privacy

Coach Max is not intended for children under 16. We do not knowingly collect data from children.

Changes

We may update this policy from time to time. Changes will be posted on this page.
