Privacy Policy

Our Commitment to Privacy

GlutenScanning is designed with privacy at its core. We believe your health data is personal and should remain private.

Information We Collect

Information You Don't Need to Provide

• No account creation required
• No email address needed
• No phone number required
• No name or personal identification

Data That Stays on Your Device

• Scan History: All scanned products are stored locally on your device
• Favorites: Your saved products remain on your device
• Settings: Your preferences are stored locally
• Search History: All searches are kept on your device

Third-Party Services

OpenFoodFacts

When you scan a barcode, we query the OpenFoodFacts database (world.openfoodfacts.org) to retrieve product information. This query includes:

• The barcode number you scanned
• Your IP address (standard for any web request)
• User agent (identifies our app)

OpenFoodFacts is a non-profit organization. Read their privacy policy at: https://world.openfoodfacts.org/privacy-policy

AI Image Analysis

When you use AI meal photo analysis, your photo is sent to the GlutenScanning analysis service, which passes it to OpenAI's API to estimate the meal's ingredients and allergens. The photo is:

• Sent securely via HTTPS
• Sent without your name, an account or a device identifier
• Not stored by GlutenScanning
• Not used by OpenAI to train its models; OpenAI may keep API data for a limited time to monitor for abuse (see OpenAI's API data policy)

Ingredient translation and recipe ideas work the same way: the ingredient text, or the list of allergens you want to avoid, is sent through the same service to OpenAI, without an account or device identifier.

No App Analytics

The app contains no analytics, advertising or tracking SDKs and does not collect usage statistics. If you choose to share analytics with app developers in your iPhone's settings (Privacy & Security › Analytics & Improvements), Apple shares crash reports with us in anonymous form.

What We Don't Do

• ❌ We don't sell your data
• ❌ We don't share your data with advertisers
• ❌ We don't track you across other apps or websites
• ❌ We don't create user profiles
• ❌ We don't access your camera without permission
• ❌ We don't store your photos

Data Security

Since most data stays on your device, it benefits from your device's built-in security:

• Protected by your device passcode/biometrics
• Encrypted when your device is locked
• Backed up to iCloud if you have backup enabled (encrypted)

Children's Privacy

GlutenScanning does not knowingly collect personal information from children. Since we don't collect personal information from anyone, the app is safe for all ages under parental supervision.

Your Rights

Since your data stays on your device, you have complete control:

• Delete Data: Clear scan history in Settings or delete the app
• Export Data: Not applicable (data is already on your device)
• Opt Out: The app collects no analytics. Crash-report sharing is set in your iPhone's settings (Privacy & Security › Analytics & Improvements)

Website Analytics

This website (glutenscanning.com) uses Google Analytics 4 to understand how visitors find and use the site. This is separate from the GlutenScanning mobile app, which does not use any third-party analytics.

Our website analytics setup is configured to be privacy-first:

• Consent required: No analytics data is collected until you click "Accept" on the cookie banner
• IP anonymization: Your IP address is anonymized before being processed
• No advertising: Google Signals and ad personalization are disabled
• No cross-site tracking: We do not share data with advertising networks
• Easy opt-out: Click "Decline" on the banner, or clear your browser's local storage to be asked again

We use analytics to count visits, see which pages are popular, and understand which search terms bring people to the site. We do not use it to identify individuals.

Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by updating the "Last updated" date at the top of this policy.
