Privacy Policy
Learn how GlutenGo AI handles your information.
Last updated: October 20, 2026
Introduction
GlutenGo AI respects your privacy. This Privacy Policy explains how we handle information when you use our mobile app and related website.
We aim to collect as little information as possible. Many app features store information locally on your device, not on our own servers.
Information We Collect
The categories below describe what information may be handled depending on how you use GlutenGo AI.
A. Account information
Firebase Authentication handles account registration, login and security, including email, account identifier, name and sign-in-related data. The reviewed mobile app's in-app Delete Account button does not yet perform account deletion; requests can be sent to support.
B. App usage information
Where enabled, GlutenGo's own Supabase analytics systems may collect user-linked feature events, scan actions, recipe and place usage, AI assistant activity, sessions and acquisition indicators. This differs from locally stored shopping lists, favorites and chat history. It is not accurate to describe every usage event as exclusively stored on the phone.
C. Product and scan information
When you scan a product, GlutenGo AI may process the barcode on your device to show product-related information.
GlutenGo AI does not store your scan history on our own servers. If you choose to save scanned products, they are stored locally on your device.
Product information may come from app data, third-party sources, or databases used by the app. Product labels and ingredients can change, so always verify the product packaging before consuming food.
D. AI chat information
When you use the AI assistant, the message you send is transmitted to OpenAI API to generate a response.
The AI assistant is designed to answer gluten-free, celiac/coeliac disease, food label, ingredient, recipe, restaurant, and gluten-free lifestyle questions.
Do not share sensitive medical information, passwords, payment information, or other highly sensitive personal information in the AI chat.
If chat history is saved in the app, it is stored locally on your device unless the app clearly states otherwise.
E. Device, advertising, and technical information
Firebase and advertising providers may process IP addresses, device data, identifiers, diagnostic and interaction information. Separately, first-party Supabase analytics may store app events linked to an account when implemented in the distributed app.
F. Diagnostics, crash reports, and logs
On both iOS and Android, the app stores and the underlying operating system may automatically collect crash reports, diagnostic logs, and performance data when the app crashes or behaves unexpectedly, such as device model, operating system version, app version, and crash stack traces.
We use this diagnostic information only to identify, understand, and fix bugs and stability issues, and to improve app performance. This information is collected by Apple and Google as platform providers and is processed according to their own privacy policies.
Diagnostic and crash information is not used by GlutenGo AI for advertising or profiling.
G. Location information
The reviewed mobile code requests camera access for product scanning and can request precise or approximate device location to search for nearby places. Search coordinates may be sent to OpenStreetMap's Overpass API. If location is unavailable, fallback coordinates can be used. Opening Google Maps is a separate action.
Specific data practices
Scanning uses the camera to read a barcode. A product lookup sends that code to Open Food Facts, whose operators may also receive IP or request metadata. Ingredients, allergens and product safety must be checked on the current package.
Nearby search can use device location and send coordinates to OpenStreetMap/Overpass operators. Returned listings and some restaurant details may contain generated examples, fallback values, or outdated information; they do not certify safety.
AI chat sends the user's message and a limited recent context, up to 18 messages in the reviewed implementation, to OpenAI. The mobile app also saves chat history locally, but provider-side handling has separate retention practices. Avoid supplying sensitive medical information.
Profile data and a self-selected gluten sensitivity preference may be stored locally. The latter can reveal health-related information but is not a medical diagnosis.
Separate first-party Supabase analytics may store user-linked feature events. On the website, Vercel Analytics operates and Google Analytics may be enabled. Google AdMob may process advertising identifiers, device details and interactions, subject to applicable consent requirements.
Local data may remain until you erase it, clear app storage or uninstall; cloud account records, AI requests, analytics, ads and service logs have different retention schedules. We will honor applicable data-access, correction, deletion and objection rights and can be reached at support@glutengo.net.
The website's contact form opens your email client; nothing is sent to GlutenGo until you send the email yourself.
How We Use Information
We use information only as needed to operate the app features you choose to use. We may use information to:
- Create and manage your login account through Firebase Authentication
- Let you access the app securely
- Provide AI responses when you send a message to the AI assistant
- Display ads through Google AdMob, depending on your consent and region
- Load recipe content stored in Supabase
- Help maintain app security and prevent abuse
- Respond to support, privacy, or account deletion requests if you contact us
We do not sell personal data for money. The reviewed mobile app saves shopping lists, product favorites and chat history locally, while some account-linked usage events may be processed in Supabase analytics systems.
AI Assistant and Health Information
GlutenGo AI provides educational information only. The AI assistant does not provide medical advice, diagnosis, treatment, or emergency support.
AI responses may be incomplete, inaccurate, or outdated. Always verify product labels, ingredient lists, allergen statements, and restaurant information before consuming food.
If you have celiac disease, coeliac disease, gluten sensitivity, food allergies, symptoms, or any medical condition, consult a qualified healthcare professional or registered dietitian before making medical or dietary decisions.
Advertising and Consent
GlutenGo AI uses Google AdMob to display ads. Depending on your location, you may be asked for advertising consent through Google's consent system.
AdMob may process advertising identifiers, IP address, device information, diagnostic information, and ad interaction data according to Google's policies and your consent choices.
You may be able to manage ad privacy choices inside the app where required, or through your device settings.
Notifications and communications
Account service communications, such as password-reset emails, may be sent through authentication providers. General mobile push notifications have not been confirmed as available in every distributed GlutenGo version.
If optional push notifications are provided, push tokens, platform, app version, delivery records and account or preference data may be processed. Permission and consent requirements apply; notifications can be disabled in your device settings, and delivery logs may have separate retention rules.
Third-Party Services
GlutenGo AI uses third-party services to operate certain app features:
Firebase Authentication
Account authentication and security; requests to delete the account are currently handled through support or the deletion website rather than the reviewed in-app button.
Sign in with Apple
Used as an optional sign-in method when you choose to sign in with your Apple ID. Apple processes your Apple ID sign-in information according to Apple's own privacy policy.
Google AdMob
Used to display ads and manage advertising consent. AdMob may process advertising identifiers, IP address, device information, diagnostic information, and ad interaction data according to Google's policies and your consent choices.
OpenAI API
Used to provide AI assistant responses. When you send a message to the AI assistant, your message is sent to OpenAI to generate a response.
Supabase
Provides managed content for parts of the GlutenGo service and first-party usage analytics. Where implemented, analytics may contain user identifiers, events, feature engagement and acquisition information, not merely public recipes.
Google Maps
The app may request device location and transmit nearby-search coordinates to Overpass/OpenStreetMap; opening an external map involves a separate provider.
Apple App Store and Google Play (diagnostics)
Apple and Google may automatically collect crash reports, diagnostic logs, and performance data on iOS and Android respectively, to help identify and fix bugs and improve app stability.
These third-party services process information according to their own privacy policies and terms.
Data Storage and Security
- Most user-created app data, such as saved products, scan history, shopping items, preferences, and chat history, is stored locally on the user's device unless clearly stated otherwise.
- GlutenGo AI does not store this local app data on its own servers.
- Account login is handled by Firebase Authentication. Recipe content is stored in Supabase. AI assistant messages are processed through OpenAI API when you use the AI chat feature. Ads are served through Google AdMob.
- We rely on reputable third-party providers to help protect information processed through their services. However, no method of transmission or storage is 100% secure.
Data Retention
- GlutenGo AI does not retain saved products, scan history, shopping lists, preferences, or chat history on our own servers when these items are stored locally on your device.
- Account information is retained through Firebase Authentication while your account exists. When you delete your account, Firebase processes deletion according to its own retention and deletion practices.
- Messages sent to the AI assistant may be processed by OpenAI API according to OpenAI's applicable API data practices.
- Recipe content stored in Supabase is app content managed by GlutenGo AI and is not user personal data.
- Some limited information may remain temporarily in third-party backups, logs, or security systems where allowed or required by law.
Your Rights and Choices
Depending on your location, you may have rights to access, correct, delete, or restrict certain personal information. You can:
- Request deletion at https://www.glutengo.net/delete-account or via support@glutengo.net; the reviewed in-app deletion button currently does not complete deletion.
- Manage advertising consent where required through the app's ad privacy choices
- Manage the camera and location permissions granted to GlutenGo in device settings and external mapping permissions separately.
- Manage or revoke Sign in with Apple access anytime from your Apple ID settings (Settings > [your name] > Password & Security > Apps Using Apple ID)
- Delete local app data by clearing app storage or uninstalling the app
- Contact us for privacy or account questions
Because saved products, scan history, shopping lists, preferences, and chat history may be stored locally on your device, deleting the app or clearing app storage may remove that local data.
Account Deletion
Request account and associated server-held data deletion at https://www.glutengo.net/delete-account or via support@glutengo.net. We may verify account ownership and retain only records permitted or required by law. The reviewed app's in-app deletion button shows a coming-soon message instead of deleting the account. Clearing the app's local data is a separate process.
Children's Privacy
GlutenGo AI is not intended for children under the age required by applicable law to use online services without parental consent. We do not knowingly collect personal information from children without appropriate consent. If you believe a child has provided personal information, please contact us.
International Users
Your information may be processed in countries where our third-party service providers operate. Privacy protections may vary depending on your location.
Changes to This Privacy Policy
- We may update this Privacy Policy from time to time.
- The latest version will be posted on this page, and the “Last updated” date will be updated when changes are made.
