Privacy Policy

Last updated: October 11, 2026

This policy explains what data the Halal Scanner iOS app (“Halal Scanner”, “the app”) collects, why, and what you can do about it. Halal Scanner is published by Obzena LLC, 30 N Gould St #45213, Sheridan, WY 82801, USA (“we”, “us”).

1. Data we collect

Data	Why	Linked to you?
Label photos you take or choose (ingredient lists, packaging, certification marks)	To read the label and produce a result	Processed in the moment, not stored on our servers
Scan results (product name, verdict, ingredient findings) and items you save as favorites	Your scan history and favorites	Linked to your anonymous identifier
Questions you type in the chat about a result	To answer your question about that product	Processed in the moment; the conversation is kept on your device
Your preferences (for example school of thought, stance on seafood, alcohol traces and doubtful ingredients, language)	To apply your own standard to results	Stored on your device and with your anonymous profile
Anonymous identifier (Firebase Authentication)	To keep your history and recognize your subscription	Yes, but it does not reveal who you are
Purchase status (via Apple and RevenueCat)	To unlock Halal Scanner Premium and restore purchases	Linked to your anonymous identifier
Support messages and feedback (your message, the email you give us if you choose to, result ratings, error reports)	To answer you and improve result quality	Linked to your anonymous identifier
Usage and diagnostics (app events, crash reports, device model, OS and app version, approximate region from the IP address)	To keep the app working and understand which features help	Not used to identify you

We do not collect your precise location, contacts, health data or advertising identifier (IDFA). The app does not ask for App Tracking Transparency permission because it does not track you.

2. How a scan is processed

1. You take or choose up to a few photos of a product label.
2. The app sends them over an encrypted connection to our backend (Google Cloud Functions for Firebase). Firebase App Check verifies that the request comes from the genuine app.
3. Our backend sends the images and your preferences to OpenAI's API, which reads the label and returns a structured result.
4. The result (not the photos) is saved to your scan history. A small thumbnail is kept on your device only.

Under OpenAI's API terms, data sent through the API is not used to train OpenAI's models. OpenAI may keep API inputs for up to 30 days to detect abuse, then deletes them.

3. How we use data

• To provide the app: scanning, results, chat, history, favorites and your subscription (App Functionality).
• To fix crashes and errors and to keep the service secure and free of abuse.
• To understand, in aggregate, which features are used and where results can be improved (Analytics).
• To answer your support requests.

We do not use your data for advertising, we do not build advertising profiles, and we do not sell or rent your data.

4. Service providers

We share data only with providers that help us run the app, under their own privacy terms:

• Google Firebase (Authentication, Firestore, Cloud Functions, App Check, Analytics, Remote Config): firebase.google.com/support/privacy
• OpenAI (label and text analysis): openai.com/policies/privacy-policy
• RevenueCat (subscription status): revenuecat.com/privacy
• Sentry (crash and error reports, without personal data): sentry.io/privacy
• Microsoft Clarity (aggregate in-app usage analytics, if enabled in your app version): privacy.microsoft.com
• Apple (App Store payments, App Attest / DeviceCheck for App Check): apple.com/legal/privacy

We may also disclose data if required by law or to protect the rights and safety of our users or of Obzena LLC.

5. Device permissions

• Camera: only to photograph product labels when you start a scan.
• Photo library: only when you choose to analyze an existing photo, or to save a result image if you ask the app to.

The app does not send notifications. Each permission is requested only when you use the feature, and you can change it at any time in Settings → Halal Scanner.

6. Retention and deletion

• Label photos: not stored on our servers after your result is produced (see section 2 for OpenAI).
• Scan history and favorites: kept until you delete them. Swipe to delete a single scan, or use Settings → Delete account in the app to erase your history, favorites, profile, local data and anonymous account at once.
• Support messages: kept as long as needed to handle your request, and no longer than 24 months.
• Analytics: kept by Firebase for up to 14 months; crash reports are kept for up to 90 days.

Deleting the app removes data stored on your device, but not your server-side history. Use “Delete account” first, or email hello@obzena.com and we will delete it for you. Deleting your data does not cancel a subscription; manage that in your Apple Account.

7. Your rights

Depending on where you live (for example under the GDPR, UK GDPR, CCPA/CPRA or KVKK), you may have the right to access, correct, delete, export or restrict the processing of your personal data, and to object to processing. Because the app works without an account, please include your request from inside the app's support form, or tell us the approximate date of your scans, so we can find your anonymous record. We respond within 30 days. You may also complain to your local data protection authority.

Our legal bases (where the GDPR applies) are performance of our contract with you (providing the app and your subscription), our legitimate interests (security, crash fixing and aggregate analytics), and your consent where required (for example for optional permissions).

8. International transfers and security

Our providers process data in the United States and other countries. Where required, transfers rely on safeguards such as the European Commission's Standard Contractual Clauses. Data is encrypted in transit (HTTPS/TLS) and access to our backend is restricted. No method of transmission or storage is 100% secure, but we work to protect your data.

9. Children

Halal Scanner is not directed at children under 13 (or the minimum age in your country), and we do not knowingly collect their personal data. If you believe a child has sent us data, contact us and we will delete it.

10. Changes and contact

We may update this policy when the app changes. The current version is always on this page, with the date at the top. Material changes will also be noted in the app.
