Privacy Policy

Last updated October 21, 2026

1000off helps you check whether the car you found is available somewhere else for at least $1,000 less. This page explains what we collect and why.

What we collect

• The link you paste and the car details we read from it (year, make, model, trim, price, mileage, VIN).
• Your approximate location (ZIP code), taken from your internet connection or typed by you, so we can search nearby and estimate shipping.
• If you sign in with Google: your name and email address from your Google account, and which car listings you opened on 1000off.
• Your search history (the cars you checked and what we found) and, if you sign in, it’s linked to your account.
• Your IP address and a random browser ID, used to give each visitor 3 free checks and to stop automated abuse. We don’t use them to identify you.

We don’t ask for your password, payment details or Social Security number, and we never see your Google password.

How we use it

• To find and show you comparable cars and estimate shipping costs.
• To show you the seller’s details for listings you choose to unlock.
• To contact you about cars you viewed and related services, such as arranging transport. You can ask us to stop at any time.

Who we share it with

We use service providers to run 1000off: Supabase (sign-in and storage), Google (sign-in), MarketCheck (car listings), Anthropic (AI that matches car trim names; it receives car details only, never your name or email) and Vercel (hosting). They process data on our behalf. We don’t sell your personal information, and we never sell or share your email address with dealers. If you ask us to help with something like transport, we’ll share the details needed for that request only with your permission.

The 1000off browser extension

The 1000off extension for Chrome works only on car listing pages. When you click its button or toolbar icon, it reads the listing you’re viewing — the page address, VIN, price, mileage, year, make, model and photo — and sends those details to 1000off so we can check for a lower price. The result appears on the page, and “View deal” opens 1000off.com. It doesn’t read other pages, your browsing history, passwords, or form entries, and it sends nothing until you click. The details it sends are handled like any other search, as described above. The extension also sends an anonymous notice when it’s installed, updated or removed, so we can count how many people use it. That notice contains only the extension version and a random number, never anything about you.

Your choices

You can use the price check without signing in. To see or delete the information linked to your account, email us and we’ll take care of it.

Changes

If we change this policy, we’ll update the date at the top of this page.
