Privacy Policy
Last updated August 15, 2026
What we collect
Your account (email address and sign-in identity) is managed by Clerk, our authentication provider. Your watchlist, plan tier, and deal history live in our database. Payments are processed entirely by Stripe — we never see or store your card number. Basic, non-identifying usage data (page loads, API requests) appears in our hosting providers' logs.
How we use it
Your email is used for deal alerts on cards you watch and for billing notices (failed payments, cancellations). Your watchlist is used to run the scanner on your behalf. That's it — we don't sell or share personal data with advertisers, and we don't send marketing email you didn't ask for.
Who processes data for us
Clerk (authentication), Stripe (payments), Neon (database), Vercel (hosting), Railway (scanner infrastructure), and Resend (email delivery). Each processes only what it needs to provide its function. Deal data itself comes from public eBay listings and public price guides.
Cookies
We use session cookies required for sign-in (set by Clerk), and Google Ads conversion-measurement cookies (Google tag) that help us understand whether our advertising works. We don't run third-party ad networks on the site or sell your data.
Your choices
You can cancel your subscription anytime from the billing portal in your dashboard. You can also delete your account and all its data yourself — the "Delete account and all data" control at the bottom of your dashboard cancels any subscription and permanently removes your watchlist, account record, and sign-in identity, immediately.
Changes and contact
If this policy changes materially, we'll note it here. Questions: contact@slabfloor.com.
