3. How We Use Your Data

• Personalise your coaching experience and recommendations
• Calculate your calorie, protein, and hydration targets
• Track your progress and generate trend analysis
• Power AI coaching conversations via our AI provider (OpenAI)
• Analyse food and nutrition-label photos you choose to scan, by sending the image to our AI provider (OpenAI) to estimate calories and macros
• Provide accountability scores and programme tracking
• Send relevant notifications and reminders
• Improve the App's features and user experience

4. Sensitive Health Data

Health-related information you provide (such as medical conditions) is treated as sensitive personal data. This information is used solely to personalise your coaching experience and is never sold or shared with third parties for marketing purposes.

Apple Health (HealthKit) and Health Connect.With your permission, the LeanerTogether iPhone app reads your step count and sleep from Apple HealthKit, and the Android app reads them from Health Connect, so they can be logged automatically. This access is read-only: we never write data to Apple Health or Health Connect. Health data obtained this way is used only to show your own progress and daily score; it is never used for advertising or marketing, never used for data mining, never sold, and never disclosed to third parties without your explicit consent. It is stored on our secure servers, not in iCloud. You can revoke this access at any time in your phone's system settings, and deleting your account deletes this data.

5. Data Sharing

We share your data only with:

• OpenAI: To generate AI coaching responses and to analyse any food or nutrition-label photos you scan. Your conversations and scanned photos are processed by OpenAI's servers to return a result; we do not store the photo after it is analysed. Please review OpenAI's privacy policy at openai.com.
• Neon (Database): Your data is stored in a secure PostgreSQL database hosted on Neon's cloud infrastructure.
• Vercel (Hosting): The App is hosted on Vercel's platform.

Other AI features (voice notes, menu and ingredient scans, the body transformation preview, and the context that personalises coach chat, which can include health conditions you have shared, though you can turn that off in your profile) also send the relevant data to OpenAI to return a result. See How we use AI with your data for the full picture.

We do not sell your personal data to any third parties.

6. Data Retention

We retain your data for as long as your account is active or as needed to provide services. Your coaching chat history and coach memory are kept for the life of your account so your coach stays consistent, and are deleted when you delete your account. If you delete your account, we will delete your personal data within 30 days, except where we are required by law to retain it.

Photos you scan (food, nutrition labels, menus) and voice notes are processed to return a result and are not stored afterwards. See How we use AI with your data for the full picture.

7. Your Rights

Under Singapore's PDPA, you have the right to:

• Access your personal data held by us
• Correct inaccurate personal data
• Withdraw consent for the use of your personal data
• Request deletion of your account and data

You can delete your account and all your data yourself, instantly, from Profile → Delete account in the app, or read how at leanertogether.com/delete-account.

To exercise these rights, contact us at chinhock@leanertogether.com

8. Security

We implement industry-standard security measures including encrypted data storage, HTTPS connections, and hashed passwords. However, no system is completely secure, and we cannot guarantee absolute security of your data.

9. Cookies

The App uses cookies and session tokens to maintain your logged-in state. These are essential for the App to function and cannot be disabled.

On our public pages we also use the Meta (Facebook) Pixel to measure how well our advertising works and to understand how visitors arrive from Facebook and Instagram. This may set advertising cookies and share limited event data, such as page views and sign-ups, with Meta. You can control ad tracking through your Facebook ad preferences and your browser or device settings.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes via email or in-app notification. Continued use of the App after changes constitutes acceptance.
