Privacy Summary
How Shelf to Cart handles shopping and scan data
This page summarizes the privacy topics shoppers most often need to understand before using Shelf to Cart.
Camera and price tag images
Shelf to Cart uses your device camera to scan grocery shelf price tags. Images are processed to extract product and price information. According to the app privacy policy, images are processed temporarily and are not permanently stored by Shelf to Cart. Saved shopping sessions store item, price, quantity, tax, and store-name data, not the original scan image. A copy of each scanned label photo may stay on your device for your current and previous shopping trip so you can double-check it. These copies are deleted automatically as you move on to later trips, and when you sign out.
OCR and AI processing
Native iOS and Android versions may use on-device text recognition, including Apple Vision and Google ML Kit. Browser scans, fallback OCR, or validation paths may use Google Cloud Vision. Extracted text or images may be sent to Google Gemini or Anthropic for price and product name identification. These services are used to turn shelf tags into editable cart items.
Optional location for tax estimates
Location is optional and used when you request automatic tax-rate detection by tapping the location icon in tax settings. Store-name suggestions when saving a trip come from your previous shopping history. When you request tax-rate detection, coordinates may be processed by Shelf to Cart servers and reverse-geocoding providers such as BigDataCloud, OpenStreetMap Nominatim, or geocode.xyz. Shelf to Cart does not maintain a user location history or use location for advertising or tracking.
Account and shopping session data
If you create an account, Shelf to Cart stores account information, preferences, shopping sessions, item prices, quantities, totals, and timestamps. Account data is stored with Supabase. Shopping sessions are kept so you can review them later unless you delete them.
