Privacy Policy
Last updated: July 14, 2026
Arbitrage Radar ("we", "us") provides a marketplace price-tracking tool. This Privacy Policy explains what information we collect and how we use it.
Information we collect
- Account information: your email address (and name/avatar if you sign in with Google) provided by our authentication provider.
- Watchlist data: the search queries, price thresholds, and marketplace selections you configure.
- Usage data: basic logs (timestamps, error reports) needed to keep the service running.
How we use it
- To run scheduled marketplace scans on your behalf.
- To send you deal-alert emails and product notifications you opt into.
- To secure the service and debug issues.
Third-party services
We use Supabase (authentication and database), Firecrawl (web scraping and LLM extraction), and a managed email provider to deliver alert emails. Public marketplace pages that we scrape (eBay, Facebook Marketplace, Craigslist, Mercari, OfferUp, Poshmark, Etsy, Depop) are only accessed to fulfill your watchlists.
Retention
Watchlists and alerts persist for as long as your account is active. Price history is stored for up to 30 days per watchlist. You can delete a watchlist at any time, and you can request full account deletion by emailing us.
Your rights
You may request access to, correction of, or deletion of your personal data by contacting jacob@pengwinning.com.
