Privacy policy

Last updated: 2026-09-13. This policy describes this installation’s current functionality. The operator must complete its identity and contact details before public launch.

Calculator inputs stay on your device

Interactive calculations run in your browser. This application does not submit your calculator inputs to a database or create user accounts. Shared tire URLs contain the selected sizes; anyone with that link can read those sizes. A web server may log the URL when it is requested.

Hosting logs

A hosting provider may retain IP addresses, requested URLs, times, browser information and errors for security and operation. Log retention and hosting-provider details must be set by the site operator before deployment.

Analytics and optional cookies

When analytics is configured, Google Analytics loads with storage denied by default and may send cookieless measurement signals such as device, page and consent-state information. It does not receive permission from this site to read or write analytics or advertising cookies unless you accept optional cookies. Your accept or reject preference is stored in local storage on this device, and you can reopen cookie preferences from the footer. Advertising integrations remain disabled until acceptance. Existing provider cookies may need to be removed through your browser settings.

Contact information

A public contact method has not yet been configured. Do not send sensitive personal or account information if an operator contact method is added later.

External websites

Source links lead to external websites with their own privacy practices. No third-party fonts or calculator libraries are fetched while using the default installation.
