This Privacy Policy describes how CalzTrack ("we", "us", or "our") collects, uses, and discloses your information when you use our mobile application and related services (the "Service").
1. Information We Collect
We collect information you provide directly to us, including:
- Account Information: Email address, display name, and authentication credentials when you sign up or sign in.
- Profile Information: Age, height, weight, gender, activity level, dietary preferences, and health goals you enter during onboarding or later update.
- Meal & Scan Data: Photos of meals, food descriptions, nutrition logs, exercise logs, and health metrics you record.

2. How We Use Your Information
We use the collected information to:

- Detect, prevent, and address technical issues or abuse.
3. AI Processing
We use third-party AI services (including OpenAI) to process meal photos and descriptions for nutritional analysis. Images and descriptions are transmitted to these services for the sole purpose of generating nutrition estimates. We do not use your personal data to train or improve these AI models beyond the scope necessary to provide the Service.
4. Data Sharing & Disclosure
We do not sell your personal information. We may share your data with:
- Service Providers: Third-party vendors who perform services on our behalf (e.g., cloud hosting, AI processing, analytics).
- Legal Requirements: If required to do so by law or in response to valid legal requests.
- Business Transfers: In connection with a merger, acquisition, or sale of assets, your information may be transferred.
5. Data Retention
We retain your personal information for as long as your account is active or as needed to provide the Service. You may request deletion of your account and associated data at any time by contacting us.
6. Data Security
We implement reasonable technical and organizational measures to protect your data. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
7. Your Rights & Choices
Depending on your jurisdiction, you may have the right to:
- Access, correct, or delete your personal information;
- Object to or restrict processing of your data;
- Data portability;
- Withdraw consent at any time (where processing is based on consent).
You can manage much of your data directly within the app. For other requests, contact us at the email below.
8. Third-Party Services
The Service integrates with third-party services such as Apple Health and Google Fit. When you connect these services, your data is shared subject to their respective privacy policies. We recommend reviewing their policies before connecting.
9. Children's Privacy
The Service is not directed to individuals under the age of 13. We do not knowingly collect personal information from children. If we become aware that a child has provided us with personal data, we will take steps to delete it.
10. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy on this page and, where appropriate, through the Service.
