**Server Log Files**

When you visit this website, our hosting provider automatically collects and stores information in server log files that your browser transmits to us. This includes:

- Content of the request (specific page)
- Access status / HTTP status code
- Amount of data transferred
- Website from which the request originated (referrer)
- Browser type and version

This data is not merged with other data sources. The legal basis for this processing is Art. 6(1)(f) GDPR (legitimate interest). Our legitimate interest lies in the technically error-free presentation and optimisation of this website.

## 5. Interactive Map (Stadia Maps)

The photo map page (`/photos/map`) uses map tiles provided by **Stadia Maps** (Stadia Maps, LLC, <https://stadiamaps.com>). When you visit this page, your browser loads map tiles directly from Stadia Maps servers located in the European Union (`tiles-eu.stadiamaps.com`). This causes your IP address and browser information to be transmitted to Stadia Maps.

Stadia Maps does not track users across websites and processes data in accordance with GDPR. For details, see their privacy policy: <https://stadiamaps.com/privacy-policy/>. A Data Processing Addendum (DPA) is available at <https://stadiamaps.com/legal/data-processing-addendum/>.

The legal basis for this processing is Art. 6(1)(f) GDPR (legitimate interest in providing an interactive map of photo locations). Map tile requests are only made when you actively visit the map page.

The map data is provided by **OpenStreetMap** contributors (<https://www.openstreetmap.org/copyright>, ODbL license) and processed into vector tiles by **OpenMapTiles** (<https://openmaptiles.org>).
