MacroDrop ("we", "our", "the app") is a nutrition and macro tracking application. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.
| Data type | Purpose | Required? |
|---|---|---|
| Email address, name (via Google/Apple Sign-In) | Account creation, authentication | Only for AI features |
| Photos of food | AI-powered food recognition (sent to Google Gemini for analysis) | Only when using photo logging |
| Voice recordings / transcribed speech | AI-powered food logging via voice (converted to text on-device, then sent to Gemini for analysis) | Only when using voice logging |
| Body metrics (sex, age, height, weight, activity level) | Calculating personalized calorie and macro targets | Yes, during onboarding |
| Food and meal logs | Core app functionality — stored locally on your device | Yes |
| Barcode scans | Looking up product nutrition info via Open Food Facts | Only when using barcode scanning |
Most of your data — meals, foods, daily goals — is stored locally on your device using an on-device SQLite database. It is not uploaded to our servers except as described below.
Account data (email, authentication tokens) is stored with Supabase, our backend provider, secured via row-level security so only you can access your own data.
| Service | What we share | Purpose |
|---|---|---|
| Supabase | Email, authentication tokens, AI usage counters | Account management, backend infrastructure |
| Google Gemini API | Food photos and transcribed voice input (when you use these features) | AI food recognition |
| Google / Apple Sign-In | Basic profile info (email, name) via OAuth | Authentication |
| Open Food Facts | Barcode number only (no personal data) | Product nutrition lookup |
We do not sell your personal data to third parties. We do not use your data for advertising.
You can delete your account at any time from Settings → Delete Account. This permanently removes your account and associated usage data from our servers. Locally stored meal data remains on your device until you uninstall the app or clear its data.
MacroDrop is not directed at children under 13 (or the relevant minimum age in your jurisdiction). We do not knowingly collect data from children.
Depending on your location, you may have rights to access, correct, or delete your personal data (e.g., under GDPR for EU/EEA users). To exercise these rights, contact us using the details below.
All data transmitted between the app and our servers is encrypted in transit via HTTPS/TLS. AI API keys are never stored on your device — all AI processing is proxied through our secured backend.
We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
