Privacy Policy for NutriScan Chrome Extension

Last Updated: January 17, 2026

Introduction

This Privacy Policy explains how the NutriScan Chrome Extension (“Extension”) handles your data. We are committed to protecting your privacy and being transparent about our practices while you use our extension on supported e-commerce platforms.

Data Controller Information

NutriScan is provided by Devtejman. We act as the data controller for the processing of ingredient data through Google’s Gemini API.

Permissions and Data Usage

The NutriScan Extension requires certain browser permissions to function:

1. Host Permissions (Amazon.in, Flipkart.com, Blinkit.com):
   • Used solely to detect when you are on a supported product page.
   • Allows the extension to extract ingredient text or capture product images (screenshots) for analysis when you click “Add to Cart”.
2. Storage Permission:
   • Used to store your daily scan quota and preferences locally on your device.
3. Identity (Google Sign-In):
   • Used to identify your account for subscription verification and cross-device quota sync via Firebase.

Data Collection and Processing

What we do:

• Extract ingredient text or images from supported product pages upon your request.
• Temporarily process these inputs to send them to Google’s Gemini API for analysis.
• Use Google Sign-In for authentication.
• Store basic user information (Email, Name, UID) and daily scan counts in Firebase Firestore to enforce usage limits.
• Manage subscriptions (Monthly/Annual) through Razorpay.
• Use Chrome’s storage sync to keep your preferences consistent.

What we do not:

• Store your photos or captured screenshots on our servers permanently.
• Store results of your ingredient analyses on our servers.
• Collect or store your credit card or payment details (all handled by Razorpay).
• Track your browsing history on sites other than the supported e-commerce platforms.
• Share your data with third parties for marketing purposes.

Usage Tiers

NutriScan offers the following tiers:

Free Tier:

• Limited to 2 image/text scans per 24-hour period.
• Basic functionality with usage restrictions.

Premium Tier:

• Monthly and annual subscription options available.
• 50 ingredient scans per 24-hour period.
• Ad-free experience and priority analysis.
• Processed through Razorpay.

Subscriptions and Billing

Subscriptions are processed entirely through Razorpay.

• All payment processing is handled by Razorpay.
• We do not have access to your full payment method information.
• We receive only subscription status and transaction IDs to verify your access level.
• Management of subscriptions, including cancellations, is handled through the NutriScan Options page or Razorpay’s customer portal.

Third-Party Services

1. Google Identity API: Used for secure authentication.
2. Google’s Gemini API: Used as the “processor” to analyze ingredient data.
3. Firebase Firestore: Used to store user metadata (UID, Email, Name) and track scan quotas.
4. Razorpay: Used for secure payment and subscription management.

Data Retention

• Images/Text: Captured data is held in temporary memory only long enough to be analyzed by the Gemini API. It is not permanently stored.
• User Profile: We store your Email, Name, and UID in Firestore. (Note: Profile pictures are NOT stored in our database).
• Quota Data: Daily scan counts are stored in Firestore to ensure your limit is respected across different devices.

Your Rights

You can manage your data directly:

• Revoke Access: You can sign out or remove the extension at any time.
