The service

Contrivance is software sold by Holbrook Tire & Glass LLC that runs on your Windows computer. It searches the supplier accounts you log in to and shows parts and prices. It does not place orders.

Paying for searches

You pay for each successful search (a punch) at the price shown on your account page. A punch counts only when the app finds the windshield and it matches the vehicle's VIN. Every counted punch is listed on your account page. You keep a card on file, and on the first day of each month that card is charged for the punches from the month before. If a charge fails, searching is paused until the balance is paid. Payments are processed by Stripe and are not refunded unless the law requires it.

Your license key

Your key is for your shop only. It works on up to 3 computers at a time. Do not share, resell or publish it. Do not copy, modify, decompile or reverse engineer the app, or try to get around the license check. We may turn off a key that is shared or misused.

Your supplier accounts

You need your own accounts with each supplier and must follow each supplier's terms. You are responsible for how you use those accounts. Supplier websites change, and a supplier can change or block access at any time, so some results may be missing or out of date until we update the app.

Check before you order

Results come from supplier and catalog data and from the VIN. Always confirm the part, price and stock with the supplier before ordering or installing. Holbrook Tire & Glass LLC is not responsible for orders placed, parts installed, or costs that come from relying on the results.

No warranty

The software is provided as is, without warranties of any kind, to the extent the law allows. Our total liability for any claim is limited to the amount you paid us in the four weeks before the claim.

Changes

We may update these terms. If we make a big change we will email you before it takes effect.
