Privacy Policy

Last updated: April 2026 · Applies to GeoItero (testspil.prutfis.dk) and Prutfis.dk

      We keep this short because we genuinely collect very little. No accounts, no passwords, no email addresses, no tracking pixels. Here is exactly what happens to your data.
    

1. What data we collect and why

Data	Where it is stored	Purpose	Who can see it
Your quiz scores (per mode and difficulty)	Your browser only (localStorage)	Show your personal best scores	Only you
Your chosen display name	Your browser (localStorage) and our leaderboard server	Identify you on the public leaderboard	Everyone who views the leaderboard
A random anonymous ID (UUID)	Your browser (localStorage) and our leaderboard server	Link your name to your score without requiring an account; allows you to update your name	Only our server (never shown publicly)
Combined quiz score percentage	Our leaderboard server	Power the public leaderboard	Everyone who views the leaderboard

We do not collect your IP address, email, location, device fingerprint, or any other personal identifiers beyond the above.

2. localStorage (on-device storage)

Quiz scores, your display name, and your anonymous UUID are stored in your browser's localStorage. This data never leaves your device unless you choose to submit a leaderboard entry. You can clear it at any time by clearing your browser's site data for this domain.

3. Leaderboard server

When you submit your name via the leaderboard input, we send your chosen name, your anonymous UUID, and your combined score to our server. The leaderboard is stored in server memory and resets periodically (every time the server restarts). We do not persist this data to a database or long-term storage. No IP addresses are logged.

4. Third-party advertising (Adsterra)

GeoItero displays advertisements provided by Adsterra. Adsterra may use cookies and similar tracking technologies to serve relevant ads. This is a third party over which we have no control. You can review Adsterra's privacy practices at adsterra.com/privacy-policy.

If you use an ad blocker, no Adsterra code will execute in your browser.

5. Cookies

We do not set any cookies ourselves. The only cookies that may be set on this site come from Adsterra's ad scripts. If you wish to avoid ad-related cookies entirely, use a browser extension such as uBlock Origin.

6. Multiplayer game data (Prutfis.dk — Fart Cloud Wars)

When you play Fart Cloud Wars, a WebSocket connection is established with our game server. Your chosen in-game name and your game actions (position, size) are transmitted in real time to other players in the same session. This data is not stored after the session ends. No account is created and no data is retained.

7. Your rights under GDPR

If you are located in the European Economic Area, you have the following rights:

Right to access — ask us what data we hold about you.
Right to erasure — request deletion of your leaderboard entry. Because entries are identified only by an anonymous UUID stored in your browser, the easiest way to remove yourself is to clear your browser's localStorage for this site (which deletes your UUID) and contact us so we can remove the orphaned entry.
Right to object — object to data processing, including ad-based tracking by Adsterra.
Right to portability — request a copy of the data we hold.

To exercise any of these rights, contact us at geoitero@gmail.com. We will respond within 30 days.

8. Data retention

localStorage data — retained until you clear your browser data. We have no access to or control over it.
Leaderboard data — retained in server memory until the server restarts (typically days to weeks). Not backed up to permanent storage.

9. Children

This site is not directed at children under 13. We do not knowingly collect personal data from children. If you believe a child has submitted personal information, contact us and we will remove it promptly.

10. Changes to this policy

We may update this policy if we change how data is handled. The date at the top of this page will reflect any changes. Continued use of the site after an update constitutes acceptance of the revised policy.
