The short version

The checker runs entirely in your browser. Your listing text, fact list and phrase lists are never sent to us or anyone else. We don't use analytics or tracking scripts, and no AI model reads your text.

What stays on your device

• Your draft, fact list, MLS limit and ignored flags are saved in your browser's localStorage so a refresh doesn't lose your work. Only this browser can read them. Clear them with the checker's Clear button or your browser's site-data settings.
• If you arrive from a link with utm_ tags, they're kept in sessionStorage for that visit so a purchase can be credited to the post you came from.
• ListingLint Pro is a single file on your computer. Its brokerage phrase list is saved in that browser's storage, or exported to a file you control.

When you buy or sign up

• Payments are handled by Stripe on Stripe's checkout page. We get your name, email and what you bought, never your full card number. A tracking reference built from the link's utm tags (for example tiktok_launch_hook-07) may be attached to the checkout. See Stripe's privacy policy.
• Email updates (optional) are handled by Kit (ConvertKit). We store your email and the same utm tags, and we send only rule-update notices. See Kit's privacy policy. You can unsubscribe from any email.
• Hosting is on Cloudflare Pages, which keeps standard server logs (such as IP address and pages requested) for security and operations.
