ShelfScout ("we," "our," "us") is a community-powered price and inventory tracking app for Walmart stores. This policy explains what data we collect, why, and how we protect it.
Account information: When you sign up, we collect your email address, a password (stored as a secure hash — we never see your actual password), and your zip code. Your zip code helps us show you nearby stores.
Location data (GPS): When you open the scanner, we request your device's GPS coordinates. We use this solely to determine which Walmart store you are at so your price scan is recorded at the correct location. We do not track your location in the background, store location history, or build movement profiles.
Scan data: When you scan a product barcode or Walmart shelf QR code, we collect the product identifier (UPC or Walmart ID), the price you enter, the inventory status you select, and the store where the scan occurred. This data is shared with the ShelfScout community to help other users find prices.
Device information: We may collect basic device information such as device type, operating system version, and app version for crash reporting and compatibility purposes.
Google AdMob: We display ads through Google AdMob to keep the app free. AdMob may collect device identifiers and usage data according to Google's Privacy Policy. You can opt out of personalized ads in your device settings.
Firebase Cloud Messaging: We use Firebase to send push notifications about price changes on your watchlist. You can disable notifications in your device settings at any time.
Supabase: Our backend data is hosted on Supabase (cloud infrastructure). Data is encrypted in transit and at rest.
Price scans you submit are visible to other ShelfScout users. This is the core function of the app — crowdsourced price data. Your scans are associated with your account for verification purposes, but other users only see the price, inventory status, and store — not your email or identity.
We retain your account data for as long as your account is active. Scan data is retained to maintain the community price database. If you delete your account, your personal information (email, zip code) is removed. Historical scan data may be retained in anonymized form.

ShelfScout is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it.
We use industry-standard security measures including encrypted connections (HTTPS/TLS), hashed passwords, and secure cloud infrastructure. No system is 100% secure, but we take reasonable steps to protect your data.
We may update this policy from time to time. We will notify you of significant changes through the app or by email. Continued use of ShelfScout after changes constitutes acceptance of the updated policy.
