# Privacy policy

WhichCarParts is a reference site, not a service you sign up for. This page explains exactly what that means for your data. Last updated 23 August 2026.

## What this site is, and what it does not collect

WhichCarParts publishes vehicle maintenance specifications: oil types, battery sizes, tire fitment, and similar reference data, organised by year, make, and model. There are no user accounts, no login, no sign-up form, no checkout, and no comments section anywhere on the site. The one interactive control, the vehicle search box, filters a list already loaded in your browser; your search text is never transmitted to a server, logged, or stored anywhere.

## Analytics

Where configured, this site uses Google Analytics 4 to understand which pages are useful. It can set cookies or similar identifiers, and collects an approximate location from your IP address, the pages you view, and general device and browser information, viewed only in aggregate. We do not run any advertising network, retargeting pixel, or data broker script on this site.

## Server logs and hosting

This site is hosted on Vercel, which keeps standard request logs (IP address, user agent, requested URL) for every visit, as any web host does. We treat Vercel as a hosting sub-processor handling that data on our behalf and do not separately collect or store it ourselves.

## Cookies

We do not set any cookies of our own. The only cookies that can appear on this site come from Google Analytics, and only when it is configured. Nothing on this site depends on a cookie to work.

## Third-party links and images

We link out to sources such as NHTSA and manufacturer documentation, and our vehicle photographs are sourced from Wikimedia Commons, credited on the [credits page](https://whichcarparts.com/credits). Once you leave whichcarparts.com, that site's own privacy policy applies, not this one.

## Children's privacy

This site is a general reference resource and is not directed at children. We do not knowingly collect personal information from anyone, of any age, because we do not collect personal information at all through the site itself.

## Your rights

If you are in the UK or EU, data protection law gives you rights to access, correct, or request erasure of personal data. If you are a California resident, the CCPA and CPRA give you similar rights. We do not sell or share personal information, and we never have.

## Data retention

We do not keep a database of visitors. Google Analytics data, when active, is retained under Google's own default retention settings, and hosting request logs are retained under Vercel's standard operational retention period, not indefinitely.

## Changes to this policy

If what this site collects ever changes, we will update this page and its last-updated date.
