Introduction

At Carby, we are committed to protecting user privacy. This policy explains how data is collected, used, and protected.

Information We Collect

• Registration information such as email and user ID.
• Authentication and login data.
• User-entered meal logs.
• Carbohydrate and calorie values.

How We Use Data

• Account creation and authentication.
• Tracking carbohydrates and calories.
• Storing and displaying meal history.
• Improving app performance and usability.

Data Storage

All data is securely stored using cloud-based database and protected using industry-standard security practices.

AI & Image Analysis

The app offers a Photograph Food feature that uses AI to estimate carbohydrate content. When you use this feature:

• Your food photo is sent to Google Gemini for analysis.
• A text prompt is sent alongside the image to identify the food and estimate nutrition.
• Values shown are estimates, not precise measurements — manual verification is advised.
• We do not store your photos on our servers.
• See Google Gemini Terms of Service for details on how Google handles your data.

Camera & Photo Library

The app requires camera access to take food photos and photo library access to select existing images. This permission is used exclusively for the food analysis feature. We never capture or store images without your consent.

Barcode Scanning

When using the barcode scanner, the barcode number is sent to the Open Food Facts open database to retrieve product nutrition information. No personal data is collected or stored during this process.

User Rights

• Access stored personal data.
• Edit or delete account information.
• Request permanent account deletion.
• Opt out of AI features — all other features work without them.
