Privacy by Design
Your privacy isn't an afterthought—it's our foundation.
Last updated: August 6, 2025
Our Core Privacy Promise
FoodGrader is built to be a private, secure place for your health information. We do not require accounts, names, or email addresses. Your dietary profiles are created on your device and associated with an anonymous identifier, not your personal identity. To provide our AI-powered analysis, the text of your profile is sent to our secure backend and stored so the app can function, but because we don't have your personal information, it is not linked back to you. We do not track you, and we do not sell your data.
Information We Collect (and Why)
We collect the absolute minimum information required for the app to function and to provide our services.
Information You Provide
- Dietary Profiles: The natural language descriptions of your dietary needs, goals, and restrictions are stored on your device. To provide our AI-powered scoring, this text is sent to our secure backend for analysis, but it is not associated with your personal identity.
Information We Collect Automatically
- Anonymous User Identifier: To manage premium subscriptions and ensure access to FoodGrader+ features, we rely on an anonymous identifier provided by the App Store. This ID is not linked to your personal identity and is used solely for managing your subscription status with our provider, RevenueCat.
- Product Barcodes: When you scan a product, the barcode is sent to our servers to retrieve nutritional information from our data sources. These requests are anonymous and are not linked to your profile or device.
- AI Analysis Data: For AI-powered features, we send anonymous data (such as product nutrition information and your anonymized dietary profile text) to our AI service providers (e.g., Google Gemini) for processing. This data is not stored by the providers after the request is completed.
Information We Explicitly DO NOT Collect
We believe in data minimization, so we have built our app to function without ever collecting:
- Your name or email address
- Your location data (IP address, GPS, etc.)
- Device identifiers like advertising IDs
- Contacts, photos (other than temporary processing of nutrition labels), or other personal files
- Third-party analytics that track your behavior across apps
Data Storage and Security
Your dietary profiles and history are stored locally on your device using its secure storage. This means your data is protected by your device's passcode and encryption. When you delete the app, this data is removed.
Third-Party Services & Data Sources
FoodGrader relies on high-quality data and services to function. We may share anonymous data with the following third parties:
- Apple (App Store): Manages the download, installation, and payment processing for subscriptions. We do not see your Apple ID or payment information.
- RevenueCat: Manages the status of your subscription using the anonymous App Store identifier.
- Google (Gemini): Our primary AI provider for analyzing food data and dietary profiles. All data sent is anonymous.
- Data Sources: To provide comprehensive product information, we retrieve data from sources including the USDA FoodData Central and Open Food Facts. We may add or remove data sources to improve quality.
Your Rights and Control
You have complete control over your data. Since we do not maintain user accounts, your data lives on your device. You can delete your profiles within the app at any time, or delete all data permanently by uninstalling the app.
Children's Privacy
We do not knowingly collect any personal information from anyone, including children. The app can be used to create profiles for children, but this information remains on the user's device and is not tracked by us.
Changes to This Policy
If we make significant changes to this Privacy Policy, we will notify you within the app. Your continued use of the app after such a notice will constitute your consent to the new terms.
