Privacy Policy

1. Overview

Chatita ("we," "our," or "the app") is a personal diabetes management companion. This Privacy Policy describes how we collect, use, and protect your information when you use our service.

2. Data We Collect

• Account information (email address, name)
• Glucose readings you log manually
• Meal photos and nutrition data
• Mood and symptom entries
• CGM integration credentials (encrypted at rest with AES-256-GCM)
• Chat messages with Chatita's AI assistant

Location: if you ask Chatita for food options near you, the app asks for your location at that moment and uses it once to look up nearby places. Your coordinates are never stored in our database or logs — only the resulting place names and distances are shared with the AI for that single reply. Declining never limits the rest of the app. / Si le pides a Chatita opciones de comida cerca de ti, la app pide tu ubicación en ese momento y la usa una sola vez para buscar lugares cercanos. Tus coordenadas nunca se guardan en nuestra base de datos ni en registros — solo los nombres y distancias de los lugares se comparten con la IA para esa única respuesta. Decir que no nunca limita el resto de la app.
