Privacy Policy

Our Policy

Zone2AI ("we," "us," or "our") provides mobile and web-based applications to help users track and optimize their Zone 2 training performance. We take your privacy seriously and are committed to protecting your personal data. This Privacy Policy explains how we handle information, including personally identifiable data ("Personal Data") and other related information.

Health Data We Process

Apple HealthKit data is processed and displayed directly on your device. We do not upload your HealthKit data to our servers, and we do not share it with advertising platforms, third-party analytics, or data brokers. All HealthKit data remains on your device and is used solely to provide in-app features. You can revoke Zone2AI's access to your HealthKit data at any time through your Apple Health settings.

Garmin Connect Data: How It Is Collected, Used, Processed, Stored, and Deleted

Connecting a Garmin account is entirely optional. If you choose to connect, you authorize Garmin to share certain fitness and activity data with Zone2AI so we can personalize your Zone 2 heart rate training. We use Garmin's Health API, Garmin's Activity API, and a Zone2AI Garmin Connect IQ watch app. We never receive or store your Garmin login credentials, and all access uses tokens issued through Garmin's secure OAuth 2.0 process.

What we collect

When you connect Garmin and as you complete activities, we may collect:

• Fitness metrics: your VO2 Max, fitness age, and resting heart rate.
• Activity and workout data: activity type and name, start time and duration, average and maximum heart rate, the detailed heart rate samples recorded during the activity, lap summaries (lap times and lap heart rate), calories, distance, and device model name.
• Training metrics reported by the Zone2AI watch app: the Zone 2 and Zone 5 time and warm-up time calculated on your Garmin device, a heart rate summary for the session (average, maximum, and minimum), the activity type and distance, whether your session goal was met, and the effort rating you optionally enter on the watch after a session.

We do not collect or store your Garmin GPS tracks, location, routes, sleep, stress, body composition, pulse ox, respiration, or any Garmin account profile or contact information. Your Garmin data is stored under an anonymous Zone2AI identifier, not your Garmin user ID.

How we use it

We use this data solely to power the app's fitness features: calculating and personalizing your Zone 2 (and Zone 5) heart rate ranges, recognizing and analyzing your workouts, tracking your training progress and goals, and generating optional AI coaching messages. We do not use Garmin data for advertising, and we do not sell it.

Where it is stored and who processes it

Your Garmin data is stored securely with Google Firebase / Firestore (a Google Cloud service), which acts as our hosting and database provider. We also rely on the following service provider, who processes this data only on our behalf to deliver an app feature:

• Google Gemini AI — if you use the optional AI coaching feature, a limited set of your metrics (VO2 Max, resting heart rate, your age range, and your recent average workout heart rate) is sent to Google's Gemini AI service to generate your personalized coaching text. This data is used only to produce your coaching text.

We use a separate product analytics service (Mixpanel) to understand feature performance and reliability. We do not send your Garmin physiological values (such as VO2 Max, resting heart rate, or workout heart rate) to our analytics service, and we never send it your Garmin credentials, location, or GPS data. These providers act as our processors under their own privacy and security commitments. We do not share your Garmin data with advertisers, data brokers, or any other third parties, and we do not sell it.

How long we keep it

We retain your Garmin data for as long as your Garmin account stays connected, so the app can show your history and trends. You can delete it at any time as described below.

How to disconnect and delete it

You can stop the data flow and delete the Garmin data we hold at any time. Disconnecting Garmin in the Zone2AI app's settings permanently deletes the Garmin fitness metrics and all Garmin workout data we store for you, retaining only the minimal identifier needed to reconnect you later if you choose. You may also revoke Zone2AI's access from your Garmin Connect account settings; doing so immediately stops any further collection and triggers deletion of the Garmin fitness metrics and workout data we hold for you. You can also request deletion at any time by emailing us at support@zone2ai.com.

Important

Zone2AI is a general wellness and fitness app. The Garmin data above is used only to personalize fitness training. It is not used to diagnose, treat, cure, monitor, or prevent any disease or medical condition, and it is not a substitute for professional medical advice.

Other Data We May Collect

We may also collect minimal non-personal data to improve the user experience, including:

• App usage analytics (e.g., feature engagement, crash reports) through privacy-compliant services like Google Analytics or Firebase.
• Basic device information (e.g., device model, OS version) for performance optimization.
• User-provided contact details (only if you voluntarily contact us for support).

We do NOT sell, trade, or rent your data to third parties.

Third-Party Services

Zone2AI may integrate with third-party services (e.g., payment processors, cloud storage providers). These services have their own privacy policies, which we encourage users to review.

Enforcement & Compliance

We regularly review our compliance with this Privacy Policy. If you have concerns or questions about how we handle data, please contact us at support@zone2ai.com.

If we receive formal written complaints, we will respond promptly and take appropriate steps to address the issue.

Changes to Our Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page, and the "Last Updated" date at the top will reflect the latest revision.

If significant changes are made, we will notify users through in-app messages or emails where applicable.

By continuing to use Zone2AI after these changes take effect, you agree to the revised Privacy Policy.

Applicable Laws

This Privacy Policy is governed by the laws of the United States of America, and we comply with applicable data protection regulations, including:

• GDPR (EU users)
• CCPA (California users)

If you access Zone2AI from outside the United States of America, you do so at your own discretion and are responsible for compliance with local laws.

Depending on your location, you may have rights regarding your personal data, including:

• The right to access any data we store about you.
• The right to request deletion of your data.
• The right to opt out of any tracking (if applicable).
