Privacy Policy

Last updated: May 2026

1. Who we are

Gramo is a mobile application for AI-powered food and nutrition tracking. We are operated as an independent developer project. For legal contact, see the Impressum.

2. What data we collect

  • Account data: email address used to register (via Supabase Auth)
  • Meal data: photos you upload, food labels, and nutrition values we calculate
  • Usage data: anonymous analytics events (via PostHog, EU region) to understand how the app is used — no personal identifiers
  • Water logs and fasting session timestamps stored locally and in your account

3. How we use your data

  • To provide the core app functionality (meal tracking, calorie history, goals)
  • To analyse food photos using Groq AI (images are processed and not stored by Groq)
  • To send optional local push notifications you configure
  • To improve the app through anonymous usage analytics
We do not sell your data. We do not use your data for advertising.

4. Food photos

Photos you upload are stored in Supabase Storage in the EU (eu-west-1). Photos are sent to Groq Cloud API for food analysis over an encrypted connection. Groq does not store images. You can delete any meal — which also deletes the photo — at any time within the app.

5. Data storage and security

All data is stored on Supabase servers located in the EU. Data is encrypted in transit (HTTPS/TLS) and at rest. We use Row-Level Security so your data is only accessible by your account.

6. Your rights (GDPR)

If you are in the EU/EEA, you have the right to:
  • Access your data
  • Correct inaccurate data
  • Delete your account and all associated data
  • Export your data in a portable format
  • Object to or restrict processing
To exercise these rights, use the "Delete Account" or "Export Data" options in the Profile tab of the app, or contact us directly.

7. Third-party services

8. Children

Gramo is not directed at children under 16. We do not knowingly collect data from anyone under 16.

9. Changes to this policy

We may update this policy. Significant changes will be notified via the app. Continued use after changes means you accept the updated policy.
