Site information

Privacy, without the fog.

Fitment North lets you calculate anonymously. Contact details are requested only if you separately ask for a partner introduction.

What stays on your device

Manual wheel and tyre values are calculated in your browser. Fitment North does not save those measurements in browser storage or send them to the server. Using the calculator does not require a name, email address or account.

Vehicle lookups

Vehicle lookup is not active in this free public version. The wheel and tyre values you enter manually stay in your browser. If licensed vehicle lookup is added later, this notice will be updated before it is enabled.

Aggregate measurement

We count three anonymous actions by day: comparisons completed, retailer interest and installer interest. These counters do not contain a name, email address, vehicle, IP address or device identifier. Indexable pages also load Google Analytics 4 (measurement ID G-PMCM6GY63D) for aggregated page measurement. Analytics storage starts denied until your consent choice is updated. GA4 events from this site do not include names, emails or other contact details.

Cookies and consent

The site initialises advertising and analytics storage as denied and waits briefly for an update before those tags run with granted storage. Google may then show a consent message on eligible pages. You can change advertising choices in My Ad Center. Cloudflare may set cookies needed to deliver and protect the site.

Advertising

Eligible public content pages use Google AdSense. Google and its advertising partners may process cookies, device information, IP addresses and page interactions to deliver, measure and protect ads, subject to your consent choices and applicable law. Google may show a consent message before eligible ads are served. You can review Google's advertising controls in My Ad Center.

Hosting

Cloudflare hosts the site and may process normal technical request data for security and delivery. Its own policies govern that infrastructure.

Optional fitment matching

If you submit a fitment request, we store the email address, optional phone number, country, location, vehicle and the current and proposed wheel and tyre measurements shown in the form. We use this information only to assess and arrange one relevant retailer or installer introduction.

Storage, retention and deletion

Fitment requests and partner coverage applications are stored in Fitment North's private site database. Partner applications contain the business and contact details, website, service areas, fitment types and notes the applicant chooses to provide. We use them only to assess and operate the founding partner pilot. For fitment requests, we first show a potential partner an anonymous summary. We tell you which partner wants the introduction and do not share your contact details until you agree. We delete or anonymise information that is no longer needed to arrange an introduction, manage the pilot, handle a dispute or meet accounting and legal obligations. To access or delete a record, email support@fitmentnorth.com and include its FN or FNP reference.

No sale or automatic sharing

We do not sell personal information or send one request to a list of partners. A request is not consent to marketing. Contact details are shared only for the named introduction you approve.

Commercial independence

Google may pay Fitment North for valid advertising activity, and a participating retailer or installer may pay for an accepted introduction. Neither route can change the geometry calculation, hide an uncertainty or purchase a fitment guarantee. There are currently no live affiliate links on this free public tool. See the commercial disclosure for the full boundary.

Your choices

You can use the calculator without sending Fitment North any contact details. Submitting the separate request form is optional and requires explicit consent. Questions can be sent to support@fitmentnorth.com.
