Privacy Policy

Last updated: November 13, 2026

At CalculatorTireSize.com ("we", "us", "our"), your privacy comes first. The site is owned and run by Saqib Ahmed and lives at calculatortiresize.com. This policy says what data we get, how we use it and how we keep it safe when you use our tire tools.

1. All Math Runs on Your Device (We Store No Car Data)

All tire math runs inside your web browser. That includes height, aspect ratio, speedometer error, gear ratios, offset, fit checks and the scale drawings.

• We do not send your tire sizes, tire brands, wheel sizes or car model to our servers.
• We do not ask you to sign up, log in, pay or give your VIN to use any tool here.

2. Information Collected Automatically

Like almost every site, some basic tech data is made each time you load a page.

• Server logs: Our web host keeps basic logs. They hold your IP address, browser and its version, system, the page that sent you here, the date and time, and the pages you asked for. We use them only to fix faults, limit floods of traffic and block abuse and attacks. Logs are deleted on a set schedule.
• Total, anonymous stats: We may look at overall traffic stats with no names attached. For example, total visits, screen widths and the country a visit came from. This helps the drawings and tables look right on every device. We build no profile of you.

3. Cookies and Browser Local Storage

We keep data use small.

• No ad or tracking cookies: We use no ad cookies from others, no trackers that follow you across sites and no marketing pixels.
• Your settings: We may use your browser's storage (such as localStorage) only to remember your settings. For example, it can keep your choice of metric units (mm, km/h) or US units (inches, mph). You can clear this at any time in your browser.

4. Messages and the Contact Form

If you write to us through our contact page or by email at support@calculatortiresize.com, we get the name, email and message you send. We use them only to read your feedback, answer fit questions or help with bugs. We never sell, rent or share your details with marketers. We keep messages only as long as we need to answer them.

5. Fonts and Links to Other Sites

• Fonts: To load fast and look clean, our site uses fonts from Google Fonts. When your browser asks for these files, your IP address goes to their server. That is how any HTTPS request works.
• Links to other sites: Our guides and tools may link to other car sites, maker docs or industry standards, such as Tire Rack or ETRTO. We do not run those sites. We are not responsible for their content, their policies or how they treat your data.

6. Your Data Rights (GDPR, UK GDPR & CCPA/CPRA)

Based on where you live, data laws may give you rights over any personal data we hold, such as emails you sent us. You may have:

• The right to see your data or get a copy.
• The right to have wrong data fixed.
• The right to have your messages deleted.
• The right to object to, or limit, how we use your data.

We have no user accounts and no profiles. So the only records we hold are messages you chose to send us.

7. Children's Privacy

CalculatorTireSize.com is a car reference site for drivers and the general public. We do not knowingly ask for or collect personal data from children under 13. In parts of Europe where the law sets the age at 16, we use 16.

8. Changes to This Policy

We may update this policy from time to time for new features or new laws. Any change will be posted here with a new "Last updated" date.
