Privacy Policy

Last updated: October 2026

Overview

World of Physics is committed to protecting your privacy. This website is designed to collect as little personal data as possible. We do not serve advertisements, and we do not sell or share personal information with third parties. Analytics services that set cookies are loaded only after you accept them in our cookie banner; if you choose "Essential only", none of them run.

What We Collect

Contact form submissions: If you use our contact form, we receive your name, email address, subject, and message. This data is used solely to respond to your inquiry and is not stored beyond what is necessary for that purpose.

Server logs: Our hosting provider may collect standard server access logs (IP addresses, browser type, pages visited, timestamps). These logs are used for technical maintenance and security purposes only, and are automatically deleted after 30 days.

What We Don't Collect

  • No advertising identifiers
  • No cross-site tracking
  • No social media tracking pixels
  • No fingerprinting
  • No analytics or session recording at all unless you accept it — choose "Essential only" and nothing in the section below is loaded

External Services

This website loads resources from the following external services:

  • Google Analytics 4 — for anonymous visitor statistics, loaded only with your consent. IP addresses are anonymized. No data is shared with third parties for advertising. Google Privacy Policy
  • Microsoft Clarity — for heatmaps and session recordings, loaded only with your consent. Clarity reconstructs how pages are used: mouse movement, scrolling, clicks and rage-clicks, and the layout of the pages you visit. It sets its own cookies and the data is processed by Microsoft, which may involve transfer to servers outside the European Economic Area. Microsoft Privacy Statement
  • KaTeX CDN (Cloudflare) — for mathematical formula rendering, loaded only with your consent. Cloudflare Privacy Policy
  • Formspree — for contact form processing, used only when you submit the contact form. Formspree Privacy Policy

We do not use Google Fonts. All typography is rendered using system fonts installed on your device. Google Analytics and Microsoft Clarity are activated only after you give explicit consent through our cookie banner.

Session Recordings and Heatmaps

If you accept analytics, Microsoft Clarity records how you interact with the page so that we can see which explanations and interactive graphics people actually use. A recording captures pointer movement, scroll depth, clicks and the rendered page, not your camera, microphone or screen outside this website.

Clarity masks text input by default, so anything you type — including in our contact form — is not meant to appear in a recording. We do not use Clarity to identify individual visitors, and we never combine it with contact form data.

You can withdraw your consent at any time by clearing this site's data in your browser, which removes the stored consent and brings the banner back. Microsoft also offers a general opt-out at choice.microsoft.com.

Legal Basis

Where this site processes data that is not strictly necessary to deliver the page — analytics, heatmaps and session recordings — the legal basis is your consent under Article 6(1)(a) GDPR, given through the cookie banner. Server logs are processed on the basis of our legitimate interest in operating a secure website under Article 6(1)(f) GDPR. Contact form submissions are processed to answer your enquiry under Article 6(1)(b) GDPR.

Local Storage

We use your browser's localStorage to remember your theme preference (light/dark mode) and your cookie consent choice. This data never leaves your device and is not transmitted to any server.

Your Rights

Under the GDPR and other applicable data protection laws, you have the right to access, correct, delete, or export any personal data we may hold about you. To exercise these rights, please contact us.

Changes

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated date.
