Privacy Policy
Last updated: October 2026
The short version: BasketChecker does not store your photos, your shopping lists, or any personal information. Photos are processed temporarily by AI to extract your list items and are immediately discarded. We hold no data about you.
Who we are
BasketChecker is a personal project operated by an individual based in the United Kingdom. It is a web application that helps you turn a photo of your shopping list into a basket at your chosen UK supermarket.
If you have any questions about this privacy policy or how your data is handled, please contact us at basketchecker@yahoo.co.uk.
What data we collect
BasketChecker collects no personal data. Specifically:
- Photos: When you upload or take a photo of your shopping list, it is sent securely to an AI service (Anthropic) to extract the list items. The photo is processed in transit and is never stored by us, Anthropic, or any other party.
- Shopping list items: The items extracted from your photo or typed into the app exist only in your browser session. They are not saved, transmitted to us, or stored anywhere once you close the app.
- No account data: BasketChecker does not require you to create an account. We hold no names, email addresses, passwords, or any other identifying information about our users.
- No analytics or tracking: We do not use Google Analytics, Facebook Pixel, or any other third-party tracking or advertising tools.
- No cookies: BasketChecker does not use advertising or tracking cookies. A service worker is installed to enable the app to load quickly — this stores only the app's own files, not any personal data.
How photos are processed
When you submit a photo, the following happens:
- Your photo is compressed within your browser before being sent anywhere
- It is transmitted securely (HTTPS) to our server function hosted on Cloudflare
- Cloudflare passes the photo to Anthropic's Claude AI API for text extraction
- Anthropic returns the extracted list items and the photo is discarded
- The extracted items are returned to your browser and displayed on screen
At no point is the photo saved to any database, storage system, or server. Anthropic's API terms confirm they do not retain API inputs beyond the duration of the API call and do not use them for model training. You can read Anthropic's privacy policy at anthropic.com/privacy.
Third parties
BasketChecker uses the following third-party services to operate:
- Anthropic — AI text extraction from photos and list processing. Data is not retained or used for training. Privacy policy →
- Cloudflare Pages — Hosting and content delivery. Privacy policy →
When you tap "Shop on [store]", you are taken to that supermarket's own website. From that point, the supermarket's own privacy policy applies. BasketChecker is not affiliated with Tesco, Sainsbury's, Asda, Morrisons or Ocado.
