HalalScanner Privacy Policy
Last updated: 6 Aug 2026
This Privacy Policy explains how the HalalScanner mobile app collects, uses and protects your information. It applies to the HalalScanner app specifically — for how this website itself handles information, see our website Privacy Policy.
Overview
HalalScanner helps you check whether a food product is halal by scanning its barcode, photographing its packaging, or typing its ingredients. This policy explains what information we collect, why, where it is processed, how long we keep it, and the choices and rights you have.
Information We Collect
Account information: your email address, used to sign you in and manage your account.
Content you provide: barcodes you scan, ingredient text you type or photograph, and photos you upload for AI food analysis or issue reports.
Usage data you create: scan history, favourites, shopping lists, and dietary and allergy preferences.
Diagnostic data: only if you enable Analytics in Settings, anonymous crash and error reports help us find and fix problems — this is off by default and nothing is sent unless you turn it on.
Why We Collect It
Your email lets you sign in and recover your account. Barcodes, ingredient text, and photos are what we analyse to produce a halal assessment. Scan history, favourites, shopping lists, and preferences let the app remember your activity and choices between sessions. Diagnostic data, only if you opt in, helps us find and fix bugs.
Third-Party Services We Use
We rely on the following external services to provide HalalScanner's features. None of them receive more information than they need to perform their specific function, and none are permitted to use your data for their own advertising.
Supabase: hosts our database, authentication, and file storage (your account, scan history, favourites, preferences, and uploaded photos are stored on Supabase's infrastructure).
Anthropic (the "Claude" AI model): analyses ingredient text and food photos you submit to help assess halal status — only the ingredient/photo data needed for that specific analysis is sent, never your email or account identity.
Open Food Facts: an open, third-party product database we query by barcode when a product isn't already in our own catalogue; only the barcode is sent, never any of your personal information.
Sentry: receives anonymous crash and error reports, and only if you have enabled Analytics in Settings — see "Diagnostic Data" below for exactly what is (and is never) included.
Diagnostic Data (Analytics)
Analytics is off by default. If you turn it on in Settings, HalalScanner sends anonymous crash and error reports to Sentry to help us find and fix problems — this never includes your email address, your full account details, product images, ingredient or OCR text, your scan history, or your exact location. Turning Analytics off in Settings stops any further reports from being sent.
Where Your Data Is Stored
Your account and app data are stored with Supabase. Photos you upload (for AI food analysis or issue reports) are stored in private Supabase Storage, accessible only to your account. We do not control the physical server locations chosen by our service providers, but we select providers who apply industry-standard security practices.
Data Retention
Your data is kept for as long as your account exists. You can delete your account at any time from Settings, which permanently removes your profile, scan history, favourites, shopping lists, preferences, and uploaded photos — see "Account Deletion" below for exactly what this does.
Account Deletion
Deleting your account (Settings → Delete Account, inside the app) permanently and irreversibly removes: your profile and display name, your scan history, your favourites, your shopping lists, your saved dietary and allergy preferences, and any photos you've uploaded. This also permanently deletes your sign-in credentials. This action cannot be undone and requires an internet connection to complete.
If you are unable to sign in to request deletion yourself, contact us at support@zavaraai.com from the email address associated with your account and we will process the deletion on your behalf. See our dedicated Account Deletion page for full details.
Security
We use industry-standard measures to protect your information, including encrypted connections (HTTPS/TLS) between the app and our servers, database-level access controls that restrict every user to their own data, and secure on-device storage for your session credentials. No method of transmission or storage is perfectly secure, but we work to protect your information using practices appropriate for the type of data we hold.
Your Rights and Choices
You can edit your display name, control your Analytics preference, and delete your account at any time from Settings. Your account email is managed through your sign-in provider and cannot be edited in-app. You may request a copy of your personal data, ask us to correct inaccurate information, or ask us questions about how your data is handled by contacting us using the details below. We do not sell your personal information, and we do not use it for third-party advertising.
Children's Privacy
HalalScanner is not directed at children and is not intended for use by anyone under the age of 13. We do not knowingly collect personal information from children under 13.
Changes to This Policy
We may update this policy from time to time. Material changes will require you to review and re-accept the updated policy the next time you open the app — see Settings for the version you last accepted.
