Third-Party Services

OpenAI (ChatGPT & GPT-4 Vision)

CycleFit uses OpenAI's services to power two features:

• Smart Coach: When you use the Smart Coach feature, your messages are sent to OpenAI's ChatGPT API to generate personalized coaching responses.
• Meal Photo Analysis: When you upload a photo of your meal for nutritional analysis, the image is sent to OpenAI's GPT-4 Vision API to identify foods and estimate nutritional content.

OpenAI processes your data according to their API Data Usage Policies:

• OpenAI does not use data submitted via their API to train their models
• Your messages and images are processed to provide responses and then deleted according to OpenAI's retention policies (typically 30 days for abuse monitoring)
• OpenAI's privacy policy is available at: https://openai.com/privacy
• OpenAI's API data usage policies are available at: https://openai.com/policies/api-data-usage-policies

Third-Party Privacy Commitment: All third parties with whom we share user data (including OpenAI) are contractually required to provide the same or equal protection of user data as stated in this privacy policy and as required by applicable privacy laws and app store guidelines. These third parties are contractually obligated to use your data only for providing the specific services you request (such as coaching and meal analysis) and not for any other purpose, including advertising, marketing, model training, or data mining. We regularly review our third-party agreements to ensure ongoing compliance with these privacy standards.

We do not share your account information, cycle data, or biometrics with OpenAI—only the specific messages and meal photos you send to the coach and nutrition features.

Apple Health & Google Fit

If you enable health data sync in Settings, CycleFit will request permission to read health data (HRV, sleep, steps, active energy) from Apple Health (iOS) or Google Fit (Android). This data is read locally on your device and sent to CycleFit's servers to personalize your experience. We do not share this data with any third parties except as described in this policy.

Tracking and Advertising

We do not track you across apps and websites for advertising purposes. CycleFit does not engage in "tracking" as defined by Apple's App Tracking Transparency framework. We do not:

• Share your data with data brokers
• Use your data for targeted advertising
• Track your activity across other companies' apps or websites
• Use third-party SDKs that engage in tracking for advertising purposes

All data collection and usage is limited to providing and improving CycleFit's health management services. If we ever introduce features that require tracking permissions, we will request your explicit consent through Apple's App Tracking Transparency prompt before any tracking occurs.

Analytics & Crash Reporting

We do not collect product analytics or crash logs via third‑party SDKs (e.g., no app analytics or crash reporting tools are installed). We may keep minimal, short‑lived server logs for security and operations (for example, to prevent abuse), and we avoid linking these to your identity unless required to protect the service.

Health Data Usage Restrictions

Your health data is protected by strict usage restrictions:

• No Advertising or Marketing: We will never use your health data (including HRV, sleep, steps, calories, cycle information, symptoms, or any other health-related information) for advertising, marketing, or other use-based data mining purposes.
• Health Management Only: Your health data is used exclusively to improve your health management through personalized training, nutrition, and recovery recommendations.
• Third-Party Restrictions: Any third-party service that processes health-related information (such as OpenAI for coach messages that may reference your health data) is contractually prohibited from using that data for advertising, marketing, or data mining. They may only use it to provide the specific health management service you requested.
• No Sale of Health Data: We will never sell, rent, or trade your health data to any third party for any purpose.
• Research Consent: If we ever wish to use aggregated, de-identified health data for health research purposes, we will obtain your explicit consent first.

These restrictions apply to all health data collected through CycleFit, whether entered manually or synced from Apple Health, Google Fit, or other sources.

Content Moderation

To maintain a safe and respectful environment, CycleFit employs automated content filtering for messages sent to the AI coach feature.

• Automated Filtering: User messages are automatically screened for inappropriate, abusive, or harmful content before being processed.
• Violation Tracking: Users who repeatedly attempt to send inappropriate content will receive warnings. After 3 violations, access to the AI coach feature will be restricted.
• Appeal Process: Users who believe their access was restricted in error may contact support@cyclefit.app to appeal the decision.
• Reporting: Users can report inappropriate responses from the AI coach by using the "Report" button on any message or by contacting support@cyclefit.app.

We take user safety seriously and continuously improve our content moderation systems to prevent abuse while maintaining a helpful coaching experience.

Sharing

We do not sell your data. We share limited data with service providers to operate CycleFit:

• OpenAI (ChatGPT) - to process coach messages and provide AI responses (only the messages you send, not your full health profile)
• Payment providers (Stripe, RevenueCat) - to manage subscriptions and billing (no health data is shared)
• Cloud infrastructure providers - to host and operate the app

All service providers are contractually required to protect your data, use it only for the purposes we specify, and comply with the same privacy standards outlined in this policy. Specifically, they are prohibited from using your health data for advertising, marketing, or data mining purposes.

Your Choices

• Consent: You can withdraw health data consent in Settings.
• Health Sync: You can disable Apple Health or Google Fit sync at any time in Settings.
• Notifications: You can enable/disable reminders in Settings.
• Delete: You can delete your account and all data from Settings. This will permanently remove all your data from our servers.

Data Retention and Deletion

We retain your data for as long as your account is active or as needed to provide you with our services. You can request deletion of your account and all associated data at any time from the Settings page in the app.

When you delete your account:

• All your personal data, health data, and logs are permanently deleted from our servers within 30 days
• Data shared with third-party services (like OpenAI for coach messages) is subject to their retention policies
• Some data may be retained for legal or regulatory compliance purposes as required by law

Data Security

We use industry-standard security measures to protect your data, including encryption in transit (HTTPS) and at rest. However, no method of transmission over the internet is 100% secure.

Children's Privacy

CycleFit is not intended for users under 13 years of age. We do not knowingly collect data from children under 13.

Medical Disclaimer

CycleFit provides personalized training and nutrition recommendations based on your health data and cycle information. These recommendations are for informational and educational purposes only and do not constitute medical advice, diagnosis, or treatment.

Always consult with a qualified healthcare professional before making any health-related decisions, starting a new fitness program, or making dietary changes. If you have any medical conditions or concerns, seek professional medical advice.

Changes to This Policy

We may update this policy from time to time. We will notify you of material changes by updating the "Last updated" date and, where appropriate, providing additional notice within the app.
