Introduction
Welcome to Pure. This Privacy Policy explains how we collect, use, and protect information when you use the Pure mobile application (the "App"). Pure is an ingredient scanner that helps you understand what is really in the food and products you consume. We are committed to protecting your privacy and handling your information with care.
By using the App, you agree to the practices described in this policy. If you have any questions or concerns, please contact us at tithipal699@gmail.com.
Information We Collect
Information you provide during onboarding
- Your first name (optional)
- Your age
- Your dietary preferences and restrictions (e.g. vegan, gluten-free)
- Your health goals and focus areas
- Known allergens or ingredients you want to avoid
This information is stored locally on your device using secure device storage. It is not linked to any personally identifiable account and is not transmitted to our servers in a form that identifies you personally.
Scan and ingredient activity
- Barcodes you scan are sent to third-party product databases to retrieve ingredient and nutritional data.
- Ingredient lists and your profile context are sent to our AI analysis backend to generate personalised ingredient analysis results.
- Messages you send to Pure AI are processed by our backend to generate responses. These messages are not permanently stored by us.
Anonymous authentication data
We use Firebase Anonymous Authentication to identify your app session. No email address, phone number, or account credentials are required or collected. An anonymous user ID is generated automatically by Firebase and is used solely for security purposes such as rate limiting.
Usage data
We may collect non-identifiable usage data such as app crashes and error logs to improve performance. This data does not include your health profile or message content.
How We Use Your Information
- To personalise ingredient analysis results based on your dietary preferences and health goals.
- To provide AI-powered responses through the Pure AI chat feature.
- To look up product ingredient and nutritional data from third-party databases.
- To prevent abuse of our backend services using anonymous session identifiers.
- To improve App performance and fix technical issues.
We do not sell, rent, or share your personal information with advertisers or marketing companies.
AI Data Processing & Your Consent
Pure uses an AI-powered backend to generate ingredient analyses and to power the Pure AI chat feature. Before these features are activated, the App explicitly asks for your permission during onboarding. You may withdraw or re-grant consent at any time in Profile → AI & Privacy.
What data is sent to the AI service
- Your first name (if provided during onboarding), used to personalise AI responses.
- Product names, brands, categories, ingredient lists, and allergen labels retrieved from scanned barcodes.
- Ingredient text captured by your device camera (on-device OCR output).
- Messages you send to the Pure AI chat assistant.
- Your profile context — dietary preferences, health goals, focus areas, and ingredients to avoid — used to personalise analysis results.
Who receives the data
The data listed above is sent to our AI analysis backend, which is hosted on Cloudflare Workers infrastructure. The backend uses Cloudflare Workers AI (and, depending on configuration, other AI model providers such as Google Gemini or OpenRouter) to generate ingredient analysis results and chat answers. Each provider is governed by its own privacy policy:
How the data is used
- Solely to produce the ingredient analysis result or chat answer that is displayed to you in the App.
- All requests are encrypted in transit (HTTPS) and authenticated with Firebase App Check tokens to prevent unauthorised access.
- Message and ingredient content is not permanently stored by us on the backend.
If you decline AI consent
If you decline or later withdraw AI consent, no personal data will be sent to any AI service. Barcode product lookups (using open product databases) will continue to work, but AI ingredient analysis and the Pure AI chat assistant will be disabled until consent is re-granted.
Third-Party Services
The App uses the following third-party services. Each has its own privacy policy that governs how they handle data.
- Google Firebase (Firebase Auth, Firebase App Check) — Used for anonymous authentication and to protect our backend API from abuse. Firebase Privacy Policy
- Open Food Facts, Open Beauty Facts, Open Products Facts — Open-source product databases used to retrieve ingredient and nutritional data from scanned barcodes. Product barcodes are sent to these services over HTTPS. Open Food Facts Privacy
- Go-UPC — A supplementary product lookup service used to find product data when other sources do not return results.
- Cloudflare Workers (our AI backend) — Our AI ingredient analysis and Pure AI chat run on a backend hosted on Cloudflare's infrastructure. Requests are authenticated using Firebase tokens and processed without permanently storing your message or ingredient content. Cloudflare Privacy Policy
Data Storage and Retention
Your profile, scan history, and saved products are stored locally on your device using device-level storage. This data is not uploaded to our servers and is deleted when you uninstall the App.
We do not maintain a server-side user database. Your anonymous Firebase session ID may be retained by Firebase in accordance with their data retention policies.
Children's Privacy
The App is designed for use by individuals aged 13 and over. We do not knowingly collect personal information from children under the age of 13. If you believe a child has provided us with personal information, please contact us at tithipal699@gmail.com and we will take steps to delete such information.
Your Rights
Because we do not collect personally identifiable information, most traditional data rights requests do not apply. However, you can:
- Delete all locally stored data by uninstalling the App.
- Withdraw AI consent at any time via Profile → AI & Privacy.
- Contact us to request deletion of any Firebase anonymous session data associated with your session.
If you are located in the European Union or California, and believe additional rights apply to your situation, please reach out to us at tithipal699@gmail.com.
Security
We take reasonable technical and organisational measures to protect your information. All communication between the App and our backend is encrypted using HTTPS. Our AI backend requires a valid Firebase App Check token on every request to prevent unauthorised access.
