Track every nutrient — not just macros

🔒 Privacy Policy

Who we are

Micro Macro Nutri Labs operates the Micro Macro Tracker mobile application ("the App"). This policy explains what data we collect, how we use it, and your rights.

Data we collect

• Account information – your email address and display name when you register or sign in with Google or Apple.
• Food & nutrition data – meals, nutrients, and food logs you enter within the App. This data is stored locally on your device and automatically synced to Firebase Firestore while you are signed in.
• Health & body data – personal data you optionally enter such as weight, height, age, sex, and body fat percentage, used solely to calculate your personalised nutritional targets.
• Workout & fitness data – workout programs, exercise logs, and session history you create in the App, stored locally and synced via Firebase Firestore while you are signed in.
• Food photos – if you use the AI food analysis feature, the photo you take or select is sent to Google's Gemini API for analysis. Photos are not stored by us after the analysis is complete.
• AI assistant queries – text messages you send to the in-app AI nutrition assistant are transmitted to our backend server for processing. These queries are not stored beyond the duration of your session.
• Device location (optional) – if you use the tap water mineral suggestion feature, the App requests your device's GPS location once to suggest a suitable tap water mineral profile for your region. This location data is not stored on our servers or on your device; it is used only in-session to produce the suggestion. The reverse-geocoding (place name lookup) uses your device's built-in geocoding service.
• Voice input – if you use voice food logging, your speech is processed by your device's built-in speech recognition. Audio is not transmitted to or stored by us.
• Authentication tokens – short-lived tokens managed by Firebase Authentication to keep you signed in securely.
• Subscription status – your in-app purchase status is managed by RevenueCat. Your account identifier is shared with RevenueCat to verify your entitlement; payment card details are handled solely by Google Play or the Apple App Store and are never visible to us.

Data we do NOT collect

• We do not store location data. The optional tap water mineral suggestion feature accesses your GPS location in-session only and does not retain or transmit that data to our servers.
• We do not collect payment card or banking information directly (handled by Google Play / Apple App Store via RevenueCat).
• We do not track your activity across other apps or websites.
• We do not sell, rent, or share your personal data with third parties for marketing purposes.

How we use your data

• To authenticate you and secure your account.
• To store, sync, and display your personal nutrition, health, and fitness logs.
• To calculate personalised nutritional targets based on body data you provide.
• To perform AI-powered food analysis when you submit a photo (data sent to Google Gemini API and not retained).
• To process AI assistant queries via our backend server.
• To manage your subscription entitlement via RevenueCat.

Third-party services

The App uses the following third-party services, each governed by their own privacy policies:

• Firebase Authentication (Google LLC) – account management and secure sign-in.
• Firebase Firestore (Google LLC) – cloud storage and sync of your nutrition and workout data while signed in.
• Google Sign-In – optional OAuth sign-in via your Google account.
• Sign in with Apple – optional OAuth sign-in via your Apple ID.
• Google Gemini API (Google LLC) – AI-powered food photo analysis. Food photos are transmitted to Google's servers for processing when you use this feature.
• RevenueCat – subscription and in-app purchase management. Your account identifier is shared with RevenueCat to verify purchase entitlements.

Data retention & deletion

Locally stored data remains on your device until you uninstall the App or clear its data. Cloud-synced data stored in Firebase Firestore is retained until you delete your account. To delete your account and all associated data, use the "Delete account" option in the App settings or contact us at the address below.

Children's privacy

The App is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. The effective date below will be updated accordingly. Continued use of the App after changes constitutes acceptance.

Effective date: 13 May 2026
