What We Collect
Visual Learning Hub collects minimal data to improve your experience:
- Analytics data — page views, device type, browser, and approximate location (country level). Collected via Cloudflare Zaraz (server-side, no client-side tracking scripts).
- Local preferences — your theme choice (light/dark) and consent preference, stored in your browser's localStorage.
We do not collect personal information, email addresses, passwords, or any form of user accounts.
How We Use It
- Understand which topics are most useful so we can prioritize content
- Monitor site performance and fix issues
- Improve the overall learning experience
Cookies & Local Storage
We use browser localStorage (not traditional cookies) for the following:
| Key | Purpose | Set When |
|---|---|---|
vlh-theme | Remembers your dark/light mode preference | Theme toggle |
vlh-consent | Stores your consent choice (granted/denied) | Consent banner interaction |
Third Parties
- Cloudflare — hosts our site and provides server-side analytics via Zaraz. Cloudflare Privacy Policy
- Google Fonts — serves web fonts. Google may log font requests. Google Privacy Policy

Advertising
This site may display advertisements via Google AdSense. If you accept cookies via our consent banner, ads may be personalized based on your browsing interests. If you reject cookies, you may still see ads, but they will not be personalized.
All tools and learning content work fully regardless of your consent choice. We never gate functionality behind ad consent.
Your Rights
- Opt out — click "Reject" on the consent banner, or clear your browser's localStorage
- Access your data — all data we store is in your browser's localStorage (open DevTools → Application → Local Storage)
- Delete your data — clear localStorage in your browser settings, or use DevTools
- Change consent — clear the
vlh-consentkey from localStorage and the banner will reappear on your next visit
GDPR Legal Basis
- Essential storage (theme preference) — legitimate interest (necessary for site functionality)
- Analytics — consent (only collected after you accept)
- Ad personalization — consent (only enabled after you accept)
