Privacy

DiffGears.com is a catalog of differential parts and an Amazon Associates site. Purchases are completed on Amazon. This page lists the cookies, pixels, and third parties that collect information here.

Google Analytics

Every page loads Google Analytics 4, measurement ID G-RJ8R52H6QR, from googletagmanager.com. Google may set cookies, including _ga and _ga_RJ8R52H6QR. Those cookies commonly last up to two years. Google receives technical information such as your IP address, browser, device, and the pages you open.

The same Analytics property also receives these events when they occur:

• view_item, when a product page loads
• add_to_cart, when you add a part
• view_cart, when you open the cart, at most once per browser session
• begin_checkout and view_on_amazon, when you continue to Amazon

An event can include the product ASIN, name, price, quantity, and, when we have them, the manufacturer and part number. These events do not include your name or email address.

This site does not load a Google Ads tag, a Facebook pixel, or any other advertising pixel.

How Google uses Analytics data is described in Google's privacy policy. You can opt out with Google's Analytics opt-out add-on, or block and delete cookies in your browser. The tag is present on the page either way. Blocking cookies stops the later requests. It does not stop a hit that already left your browser.

Cart storage in your browser

The cart is kept in your browser with localStorage, under the name cart. It stores the ASIN, name, part number, price, quantity, and image address of each part you add, so the cart is still there on a later visit. That information stays on your device. It is not sent to a DiffGears server.

A sessionStorage flag named dg_view_cart_tracked remembers that the cart-view analytics event already ran during this visit.
