DietLens

Privacy Policy

DietLens (“DietLens”, “we”, “us”) is a food-scanning and AI nutrition-coaching app operated by DietLens (“the Company”). This policy explains what we collect, how we use and share it, your choices, and how to delete your data. By using DietLens you consent to the practices described here. If you do not agree, do not use the app.

1. Information we collect

• Account information: when you sign in with Google, we receive your name, email address, profile photo, and a unique account identifier.
• Profile information you provide during setup: age, gender, height, weight, goal weight, activity level, main goal, training habits, meal and cooking preferences, dietary preferences, allergies or foods to avoid, obstacles, and any custom goal text you enter.
• Food and scan data: photos of meals and menus you scan, and the resulting nutrition estimates, scores, notes, and the items you choose to log.
• Health and fitness data via Health Connect — see Section 4.
• Subscription data: your subscription status and entitlements.
• Diagnostic and usage data: feature usage, scan counts, and limited technical logs used to operate, secure, and debug the service. We do not use any third-party analytics or advertising SDKs.

2. How we use your information

• To analyze the photos and food descriptions you submit and to estimate nutrition, goal-fit, and coaching responses.
• To personalize your daily calorie and macro targets, AI tasks, insights, and coaching, based on your profile.
• To operate, maintain, secure, and improve the app, and to prevent abuse (rate limiting and fraud prevention).
• To send optional reminders if you enable notifications.

We process health-related profile details only to provide these features, on the basis of your consent.

3. AI processing

To generate scan results, nutrition estimates, coaching replies, insights, daily tasks, and your nutrition plan, we send the relevant content — such as your scan photos, the food text you enter, your coaching messages, and relevant profile details — to Google Vertex AI (Gemini), which processes it on our behalf to return a result. This content is processed under Google Cloud’s terms and is not used to train Google’s foundation models. We do not send your Health Connect activity data to the AI.

4. Health Connect

If you connect Health Connect, DietLens reads (read-only) your steps, active energy burned, distance, and workout sessions to show your daily activity on the home screen.

• This Health Connect data is used only on your device to display your activity. It is not uploaded to our servers, not shared with any third party, and not sent to the AI.
• We never use health or fitness data for advertising, to determine employment or insurance eligibility, or for any unauthorized sharing.
• You can grant or revoke this access at any time in your device’s Health Connect settings.

5. How your information is stored and shared

We store your data on Google Cloud using Firebase (Cloud Firestore, Cloud Storage, and Cloud Functions). Scan photos are stored as compressed thumbnails linked to your account. We share data only with service providers that process it on our behalf:

• Google (Firebase, Cloud Storage, Vertex AI, Firebase Cloud Messaging) — hosting, storage, AI processing, and push notifications.
• RevenueCat and Google Play — to process and manage your subscription; we share your account identifier and subscription status.

We do not sell your personal information, and we do not share it with third parties for their own advertising. We may disclose information if required by law or to protect the rights, safety, and security of our users and the service. Your data may be processed on servers located outside your country.

6. Data retention

• Your account, profile, scans, logs, and history are retained while your account is active.
• Coach chat history is automatically removed after about 30 days, and older in-app notifications are removed once a limit is reached.
• You can delete individual scans at any time.
• When you delete your account (Section 7), we delete the personal data associated with it, except limited information we must keep for legal, security, or fraud-prevention reasons, retained only as long as necessary.

7. Your choices and deleting your data

• You can edit your profile any time in Settings, and turn notifications on or off in your device settings.
• Account and data deletion: you can request deletion of your account and the data associated with it at any time — in the app via Settings (where available), or by emailing dietlensapp@gmail.com from your account email address. We complete deletion within 30 days, subject to the retention exceptions above. See: How to delete your account & data.
• Depending on your location, you may have rights to access, correct, export, or delete your data and to withdraw consent. Contact us to exercise them.

8. Security

We use industry-standard safeguards, including authenticated access, encryption in transit, and server-side access controls. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

9. Children

DietLens is not intended for anyone under 13 years of age. We do not knowingly collect data from children under 13. If you believe a child has provided us data, contact us and we will remove it.

10. Health disclaimer

DietLens provides estimates and general wellness information. It is not medical advice and is not a substitute for a doctor, dietitian, or other qualified professional. Always consult a professional before making significant changes to your diet, especially if you have a medical condition.

11. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by an updated version and date, and we may ask you to review and accept the revised policy.
