Overview
MarketCheck is a browser extension that helps users analyse Facebook Marketplace listings for price comparison and potential scam detection. We are committed to protecting your privacy.
Key Point: We do not collect, store, or sell any personal information.
Information We Access
When you click "Check this listing", the extension reads:
- Listing title, description, and price
- Seller's public profile information
- Listing images (URLs only)
- Item condition and location
How We Use This Information
Data is sent to our analysis API to identify the product, compare prices, and assess potential risks. Analysis is performed in real-time and we do not store your analysis history.
Data Storage
We only store locally on your device: panel position preference and temporary cache for the current session. This data never leaves your device.
Data Sharing
We do not sell data to third parties, share with advertisers, track browsing history, or collect personally identifiable information.
Third-Party Services
Our API uses Anthropic's Claude AI. The "Check images online" feature uses Google Lens.
