GlucoAI Privacy Policy

Last updated: March 19, 2026

1. Introduction

GlucoAI ("we", "our", "us") is a diabetes tracking application developed by Ignis Algos. This Privacy Policy explains how we collect, use, and protect your information when you use the GlucoAI mobile application ("the App").

2. Information We Collect

Health Data (stored locally on your device only): Blood glucose readings, insulin doses, meal logs, carbohydrate counts, and other diabetes-related data you enter into the App. This data is stored in an encrypted local database on your device and is never uploaded to our servers.

Food Photos (processed ephemerally): When you use the AI Food Scanner, your meal photo is sent to Google's Gemini API via a secure Firebase Cloud Function for analysis. The photo is processed in real-time and is not retained by our servers or by Google after analysis is complete.

Account Information: If you create an account, we collect your email address for authentication via Firebase Auth.

Purchase History: If you subscribe to GlucoAI Premium, purchase data is processed by RevenueCat for subscription management.

Device Identifiers: Firebase App Check uses device attestation (Play Integrity on Android) to prevent abuse. No advertising identifiers are collected.

3. How We Use Your Information

To provide diabetes tracking and AI-powered carb estimation
To generate personalized health reports and data exports
To manage your subscription (via RevenueCat)
To prevent abuse of our AI services (via Firebase App Check)

4. Data Storage and Security

Your health data is stored locally on your device only using the Hive encrypted database. It is never uploaded to our servers unless you explicitly export it. All network communications use HTTPS/TLS encryption.

5. Third-Party Services

Google Firebase: Authentication, Cloud Functions (Gemini proxy), App Check
Google Gemini API: AI food analysis (photos processed ephemerally, not stored)
RevenueCat: Subscription management
Nightscout / Dexcom: CGM data (only if you connect your CGM; credentials stored locally)

These services have their own privacy policies governing data use.

We do not use your data for advertising
We do not store your health data on our servers
