Privacy Policy & Terms of Service

Effective date: 23 June 2026 · Last updated: 23 June 2026

This page explains how the Halal & Healthy application (the "App", "we", "us", or "our"), published by Tag'In Tech , handles your information, and the terms under which you may use the App. By installing or using the App, you agree to this Privacy Policy and to the Terms of Service set out below.

1. Overview

Halal & Healthy lets you scan product barcodes to look up food products and additives (E-codes), check their halal and nutritional status, save favourites, view scan history, and receive optional reminders. You can use the core features of the App without creating an account . We do not require your name, email address, or a sign-in to use the App.

Most of the data you generate (favourites, scan history, and settings) is stored locally on your device and is not transmitted to us. A limited amount of diagnostic and usage data is processed by third-party services described below to keep the App stable and to understand how it is used.

2. Data we collect

Category	What & why	Where it goes
Camera input	Used to scan product barcodes and, optionally, to take product photos you choose to contribute. Barcode scanning is processed on your device.	On-device; photos only if you choose to upload (see Open Food Facts).
Photos / media	If you choose to add or contribute a product image, you may select a photo from your gallery and crop it.	Uploaded only when you submit it to Open Food Facts.
Notification token	A device push token issued by Firebase Cloud Messaging, used to deliver the App's reminder and update notifications. It identifies the installation, not you, and is created only while notifications are enabled.	Google (Firebase Cloud Messaging).
Diagnostics / crash data	Crash reports and stack traces, device model, operating-system version and app version, collected to diagnose and fix problems.	Google (Firebase Crashlytics & Performance).
Usage & analytics data	Anonymous/aggregated interaction events, app open counts, screen views, and device identifiers including the advertising identifier (Android AD_ID), used to understand usage and improve the App.	Google (Firebase Analytics).
Contact form	If you write to us through the in-app contact form, the message you type and the reply address you enter are sent to us so we can answer you. Sending a message is entirely optional.	Our contact endpoint on halalapp.app, forwarded by email to [email protected].
Locally stored content	Favourites, scan history, language and theme preferences, and onboarding state.	Stored only on your device. Removed when you uninstall the App.

We do not collect your name, email address, contacts, or payment information, and we do not sell your personal data.

3. Device permissions

The App may request the following permissions, each used solely for the stated purpose:

Camera — Scan barcodes and capture product photos Photos / Storage — Select and crop a product image to contribute Notifications — Send scan reminders and update notices (can be turned off) Internet — Look up product data and load images Flashlight — Torch while scanning in low light Vibration — Scan feedback Advertising ID — Analytics measurement (Firebase)

You can grant or revoke these permissions at any time in your device settings. Denying a permission only disables the related feature; the rest of the App continues to work.

4. How we use data

Provide core features: barcode lookup, additive (E-code) information, favourites, and history.
Send the reminder and update notifications you have not turned off.
Maintain stability and fix crashes (diagnostics).
Understand aggregate usage and improve the App (analytics).
Display product information and images retrieved from third-party data sources.

We do not use your data for automated decision-making that produces legal or similarly significant effects on you.

5. Third-party services

The App relies on the following third-party services, each governed by its own privacy policy:

Google Firebase (Analytics, Crashlytics, Performance Monitoring, Cloud Messaging) — diagnostics, usage measurement and the delivery of push notifications. Firebase privacy · Google Privacy Policy .
Open Food Facts — the open, collaborative food-product database used to look up products and additives. Product data shown in the App comes from Open Food Facts, and any photo, edit, or contribution you submit becomes part of their public open database (licensed under the Open Database License). Open Food Facts privacy .
Google Translate — used to translate product or additive text; the text to be translated is sent to Google's translation service. Google Privacy Policy .
In-app review — used to optionally prompt you to rate the App, through Google Play on Android and the App Store on iOS.
Resend — the email provider that forwards messages sent through the in-app contact form to our inbox. Resend privacy .

7. Retention & deletion

On-device data (favourites, history, settings) is kept until you delete it within the App or uninstall the App.
Diagnostics and analytics data held by Firebase is retained according to Google's retention policies and our configured retention settings.
Contact-form messages are kept in our mailbox for as long as needed to answer you and to keep a record of the exchange.
Contributions to Open Food Facts (e.g. photos you upload) remain part of their public open database and are governed by their terms.

To request deletion of diagnostic/analytics data associated with your device, contact us at the address below and identify your device where possible.

8. Security

Network requests to product-data and Google services use encrypted (HTTPS/TLS) connections. While no method of transmission or storage is completely secure, we take reasonable measures to protect the limited data the App processes.

9. Children's privacy

The App is not directed to children under 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal data from children. If you believe a child has provided us with data, please contact us so we can remove it.

10. Your rights

Depending on where you live (for example under the EU/UK GDPR), you may have the right to access, correct, delete, or restrict the processing of your personal data, and to object to certain processing. Because most data stays on your device, you can exercise many of these rights directly by clearing data in the App or uninstalling it. For diagnostic/analytics data, you can opt out by denying the advertising-ID permission and you may contact us to make a request. You also have the right to lodge a complaint with your local data-protection authority.

11. Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date at the top of this page. Continued use of the App after an update constitutes acceptance of the revised policy.
