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.

Optional analytics and advertising

Analytics and advertising are disabled unless configured. If optional integrations are configured, this site asks before loading them and stores your accept or reject preference in local storage on this device. Google services, when enabled and accepted, may receive identifiers, device information and usage events. You can reopen cookie preferences from the footer. Rejecting stops future loading after a refresh; 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.
