Last updated: July 2025

1. General Information

We are committed to protecting your privacy and personal data in accordance with the General Data Protection Regulation (GDPR) and all applicable data protection laws. This privacy policy explains how we collect, process, and use your data when you use the GeoLineup website.

2. Controller and Contact

The data controller responsible for data processing on this website is:

3. Data Collection and Processing

a) Website Access Data

When you visit this website, the following data is automatically collected by the web server and stored in log files for security and technical reasons:

IP address (anonymized, not personally identifiable)
Date and time of access
Browser type/version and operating system (if sent)
Accessed pages/URLs

This data is used solely to ensure the proper functioning, security, and optimization of the website and is not merged with other data sources.

b) Web Analytics with Matomo (self-hosted, cookieless)

We use the open-source analytics software Matomo for website analytics.
Matomo is hosted on our own server in the European Union and is operated without the use of cookies.
We have configured Matomo for IP anonymization and do not store any data that could directly identify you as an individual.

No personal profiles are created.
No tracking cookies, advertising cookies, or third-party tracking tools are used.
You can prevent analytics processing at any time by enabling the "Do Not Track" setting in your browser.

Legal basis: Art. 6(1)(f) GDPR (legitimate interest in analyzing and improving our offering).

In addition to general page usage statistics, we also use Matomo to track anonymous gameplay data in GeoLineup. Specifically, we record:

Selected game level (e.g., easy, medium, hard)
The set of cities shown in each round (as anonymized IDs)
The latitude distance between cities (for game balancing purposes)
If a game was canceled or aborted (without personal data)

This helps us evaluate and improve the fairness and functionality of the game mechanics. No personal data or user profiles are stored, and the information is never linked to individuals.

c) Feedback Survey (Nextcloud Forms)

We offer an optional user feedback survey to help us improve the project.
This survey is conducted via Nextcloud Forms on our own Nextcloud instance, which is securely hosted by Hetzner Online GmbH in Germany (EU).
Participation in the survey is voluntary. No personal data is required unless you choose to provide it (e.g., in free text or an email address field).

All survey responses are transmitted in encrypted form and stored exclusively on our Hetzner-hosted server within the European Union.
The data is not shared with third parties and is processed in accordance with the GDPR.
For more information, please refer to the privacy policy of Hetzner Online:

d) Contacting Us

If you contact us by email or via the contact form, the data you provide will be used solely to process your request and will not be shared with third parties.

4. Cookies

Cookies may be used for technical reasons (e.g., saving language preferences or session state), but not for advertising or profiling.
