Privacy Policy

Last updated: March 2026

Overview

Cull is operated by Homespect Ltd, a company registered in England and Wales, trading as Cull ("we", "our", or "the app"). We are committed to protecting your privacy. This policy explains how we handle your data when you use our grocery health scanning app.

The short version: We collect minimal data, we don't run ads, and we never sell your information.

What We Collect

Device Identifier We generate an anonymous, randomly generated UUID stored on your device. This is used to authenticate API requests and associate your data across sessions. It is not linked to your name, email, or Apple ID. It resets if you uninstall and reinstall the app.

Camera & Photos Camera access is used to scan product barcodes and labels. Photos taken for scanning are processed on-device and/or sent to our servers for product identification — they are not stored beyond the scan session. When you submit a product to the community database, those photos are uploaded, processed (background removal, quality enhancement), and stored permanently as part of the shared product catalogue.

Country Code We request approximate location permission to determine your country (ISO country code only, e.g. "GB"). This is used solely to suggest products available in your region. We do not collect or store GPS coordinates, city, address, or movement data. If you deny location permission, we fall back to your device's locale setting.

Search Queries Product searches you perform are sent to our servers to return results. Search queries are not permanently stored or linked to your identity.

Scan History & Favourites Products you scan and favourite are stored on your device. When you sign in with Apple, this data syncs to our servers so it is available across your devices.

AI Chat Messages Messages sent to the AI Nutritionist are sent to our servers for processing. Chat conversations are not stored permanently on our servers.

Dietary Profile Your dietary preferences, restrictions, and allergens are stored locally on your device only to personalise health scores. This data is never sent to our servers.

Apple Sign-In If you sign in with Apple, we receive an opaque identifier to sync your data across devices. We never see your email address unless you choose to share it.

Crash Reports We use Firebase Crashlytics to collect crash logs and diagnostic data when the app crashes. This may include device model, OS version, and the state of the app at crash time. No personal data is included in crash reports.

Community Submissions Product photos and data you submit are uploaded to our servers, processed by our image pipeline, and stored in the community database. Submission metadata (status, timestamps) is associated with your anonymous device identifier.

What We Don't Collect

Precise GPS location (country code only)
Your name or email (unless you choose to share it via Apple Sign-In or contact support)
Payment information (subscriptions are handled entirely by Apple)
Advertising identifiers
Usage analytics or behavioural tracking
Contacts, health data, or browsing history

Advertising

Cull does not display advertisements. We do not collect data for advertising purposes, and we do not share any data with advertising networks.

Third-Party Services

Cull API — our own backend, hosted on Vercel, for product data, AI analysis, and community features
Open Food Facts — open-source product nutrition database (no personal data shared)
Apple — authentication (Sign in with Apple) and subscription/payment management
Firebase Crashlytics (Google) — crash reporting only (analytics disabled)
Google Gemini — AI-powered data extraction from product photos (server-side, no personal data)
Upstash — database hosting for product and community data

Data Storage & Deletion

Your dietary profile is stored only on your device. Scan history, favourites, and submissions are stored both on your device and on our servers.

You can clear your local history and favourites anytime in Settings. To request deletion of server-side data, contact privacy@getcull.com.

Community product submissions remain in the shared database after deletion of your account, as they benefit all users. Personal identifiers are removed from submissions upon account deletion.

Data Sharing

We do not sell, trade, or transfer your personal information to third parties. Product photos may be processed by third-party GPU services for image enhancement — these services process data in transit and do not retain it.

Children's Privacy

Cull does not knowingly collect information from children under 13. The app is intended for general audiences making grocery shopping decisions.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted within the app and at getcull.com/legal/privacy with an updated date.
