Privacy policy

Last updated: June 14, 2026

Important: Tire comparison results are estimates for planning only. This site does not provide mechanical certification, OEM approval, or on-vehicle clearance guarantees. Confirm final tire fitment, load/speed ratings, and speedometer calibration with a qualified tire professional or your vehicle and tire manufacturer before driving.

This privacy policy describes how the Tire Size Calculator website (“we”, “us”) handles information when you use our automotive informational tools, including the tire conversion tool experience and related pages. We aim to be transparent, minimal, and practical—this is not mechanical or automotive certification advice.

Scope and non-certification

This website does not provide mechanical or automotive certification advice. Tire calculations are for informational comparison purposes only. You should verify final tire fitment, load/speed ratings, and vehicle compatibility with qualified professionals or manufacturers before purchasing or installing tires.

Data collection

We do not require an account to use the calculator. We do not intentionally collect sensitive personal data or vehicle ownership records as part of normal browsing. No sensitive personal or vehicle ownership data is stored by us unless you voluntarily submit it (for example, through the contact form fields you choose to provide).

Cookies usage

We may use a minimal set of cookies or similar technologies that are necessary for site operation, security (such as CSRF protection on forms), and preferences where applicable. Preference-related storage may include theme selection stored in your browser (for example, via localStorage) to improve repeat visits.

Analytics tracking

We may use privacy-conscious analytics to understand aggregate traffic, performance, and errors. Where enabled, analytics is intended to be configured toward anonymous usage tracking and aggregated reporting rather than profiling individuals.

Third-party services

The site may load fonts or assets from reputable third-party providers (for example, a font CDN). Those providers may process technical data such as IP addresses according to their own policies. Embedded third-party content, if added in the future, will be disclosed here.

Browser storage

Features such as recent comparison history may store values on your device to improve convenience. Where used, that data remains under your control and can typically be cleared via browser settings.

Server logs

Like most websites, servers may automatically record technical information (for example, IP address, user agent, timestamps, and requested URLs) for security and reliability. We retain logs only as long as needed for those purposes unless a longer period is required by law.

Contact information

For privacy-related requests, please contact us through the contact page. Include enough detail for us to verify and respond responsibly.

User rights and privacy protection

Depending on your jurisdiction, you may have rights to access, correct, delete, or restrict certain processing of personal data, or to object to certain processing. We will respond to valid requests consistent with applicable law. If we cannot verify a request, we may ask for additional information.

Data security

We use reasonable administrative and technical measures designed to protect information submitted through this site. No method of transmission or storage is completely secure; use the tools at your discretion and avoid submitting unnecessary sensitive information.

Children’s privacy

This site is intended for a general audience interested in automotive planning. It is not directed to children, and we do not knowingly collect personal information from children.

Changes

We may update this policy to reflect product changes or legal requirements. Material changes will be reflected by updating the “Last updated” date and, where appropriate, additional notice on the site.
