Privacy Policy
Last updated: 30 July 2026
EasyTireSize (“we”) respects your privacy. This policy explains what we collect, how we use it, and how we protect it, in line with Thailand’s Personal Data Protection Act B.E. 2562 (PDPA).
1. Information we collect
This site is a static set of calculators with no user accounts. We do not ask for or store identifying information such as your name, email, or phone number.
Values you enter into the calculators (such as tire or wheel sizes) are processed entirely in your browser and are never sent to our servers.
2. Cookies and analytics
We use Google Analytics to understand overall usage and improve the service. It starts collecting automatically (via Google Consent Mode), and you can press “Decline” in the cookie consent banner at any time to stop it.
The data Google Analytics collects is aggregate and non-identifying — for example pages visited, device type, and approximate country.
3. Data stored on your device (localStorage)
This data lives in your own browser, is not sent to us, and you can remove it by clearing site data in your browser.
- Your light/dark theme preference, so the site remembers how you like it displayed.
- Your cookie consent choice, so the consent banner isn’t shown again.
4. Third-party services
- Google Analytics (provided by Google LLC) for usage statistics, once you consent.
- Google Forms, if you choose to submit feature suggestions through our form link — that data is governed by Google’s policies.
5. Your rights under the PDPA
You have the right to access, correct, delete, or withdraw consent to data collection. Because we hold no identifying data, you can withdraw analytics consent at any time by clearing cookies/localStorage or pressing “Decline” in the consent banner.
6. Changes to this policy
We may update this policy from time to time. The most recent revision date is shown at the top of this page.
