The respective artists and event organizers are responsible for the rights to and accuracy of the content displayed in the K1 App, including information about exhibitions, artists, events and image credits. The K1 App displays, among other things, content provided by artists and galleries.
The K1 App is a digital guide for a gallery tour in Cologne, Germany.
The app is officially offered through both the Google Play Store and the Apple App Store.
No registration or user account is required to use the K1 App. No personal information needs to be entered for normal use of the app.
The K1 App is developed using the no-code development platform Thunkable and is provided for Android and iOS.
The operator of the K1 App does not generally collect personal data through the app for the purpose of creating user profiles.
In particular, the K1 App does not create user accounts or personal profiles.
The K1 App does not provide functions for entering or storing names, email addresses, telephone numbers or similar personal information.
This does not affect voluntary communication with the operator, for example by email. If a user contacts the operator, the personal data provided in that communication will be processed to handle the respective request.
The K1 App may use the location of the mobile device when location-based functions are used.
Access to the device location requires the user's permission through the respective operating system.
Location data is used in particular to support orientation during the gallery tour and to provide location-based navigation functions.
The K1 App does not create a personal movement or location profile and does not permanently store location data on servers operated by the K1 App operator.
If a user requests directions from their current location to a gallery, the K1 App creates a specially constructed URL for Google Maps. This URL contains the location information required for route calculation.
By opening this URL, a connection to Google is established. The information contained in the URL may be transmitted to Google and processed by Google.
The K1 App does not permanently store this location or route information on its own servers.
Users can change or revoke the location permission at any time through the settings of their mobile device. Without location permission, location-dependent functions may not be available or may only be available to a limited extent.
The K1 App uses Google Maps Platform and the Google Maps SDK to display maps and provide map-related functionality within the app.
The Google Maps SDK is integrated into the Android and iOS versions of the app.
When the Google Maps SDK is used, technical information may be transmitted to and processed by Google. Depending on the platform, SDK version and specific use, this may include information about the device being used, IP address, technical usage information, diagnostic or crash information, and information relating to the use of map functions.
When location-based functions are used, location information may also be processed.
The specific processing carried out by Google is governed by Google's privacy policy and the technical terms applicable to Google Maps Platform.

We do not have complete control over the processing of personal data carried out by Google.
The route-planning function does not use the Web Viewer contained in the K1 App.
Instead, the K1 App opens a specially constructed Google Maps URL for this purpose.
When Google Maps is opened, information required for route calculation may be transmitted to Google. This may include, in particular, the starting point or current location, the destination and technical connection data.
Any subsequent processing by Google is governed by Google's privacy policy.
