3. What personal data is processed?

The LiquidEarth app has been designed so that little personal data needs to be processed in order to use it. However, the full functionality of the app is only available to you if you are registered and have shared further personal data with us. If, in addition, we wish to process personal data that is not directly required for the use of the LiquidEarth app, we expressly ask you to consent to the respective data processing.

In order for you to be able to assess the type and scope of data processing, we explain below exactly what data is processed in connection with the LiquidEarth app:

3.1 Technically necessary connection and location data

  • IP address

  • User Agent (terminal type and operating system)

  • Date and time of access

  • HTTP Status Code

  • URL and referrer URL

  • user uploaded content

  • When spatial anchors are set , limited location data.

  • When using the app in AR mode, the camera data is used for providing the background of the AR session. This data never leaves your device.


4. Functions of the app and purposes of data processing

In the LiquidEarth app, the personal data just explained are processed in order to provide the various functions of the LiquidEarth app and to protect it against misuse and manipulation. We explain the different processing purposes in detail below:

4.1 Basic functions of the LiquidEarth app and informational use

You can download the LiquidEarth app without registering. However, then you can only use the LiquidEarth app when logged in with a registered user account. Location data will only be processed if you consent to this use.

4.2 Profile and login

You can use some functions of the LiquidEarth app only if you are registered and logged in. The email address, password and username are used for authentication when you login via the app. Through the login we can protect the LiquidEarth app against misuse and manipulation. Your username is used to enable the LiquidEarth app to address you appropriately. You may find more information regarding the registration data in our privacy policy on your website.

4.3 Data processed during operations of the LiquidEarth App

While the App is being used, it frequently communicates with the LiquidEarth backend services over a TLS secured connection to load data or process user requests. Processing and response of these requests require your devices IP address to be temporarily stored in our backend.

You can share spaces with other Liquid Earth Users for collaboration. Sharing a space requires You to enter the email address of the user you want to share a space with. Sharing a space with another user will allow that user to view your email address that is stored in the spaces meta data.

While using the real-time collaboration features of the Liquid Earth App (“Multiplayer”) your username is transmitted and visible to other users to identify users in the current session. Real-time collaborative sessions can only be established between users with common access to a shared space. Therefore, your username and email address is not visible to other users as long as you have not shared a space with them.

5. What permissions does the app require on the functions of the end device?

In order to use all the functions of the LiquidEarth app, the LiquidEarth app needs permission to access various functions of your end device.

5.1 Technical requirements

In order to use the LiquidEarth app, an active internet connection of the terminal device is required. The app can be used with limited functionality in offline mode that operates with data previously cached on the device.

5.2 Possible additional permissions

The LiquidEarth app also needs access to the following features of your terminal device if you want to use all features of the LiquidEarth app. Before the LiquidEarth app can access these end device features, you will be explicitly asked for your consent.

a. Camera

If you want to use the augmented reality features, you must allow the LiquidEarth app to access the camera of your end device.

b. Location

If you manually enable location data or set spatial anchors, the LiquidEarth app needs permission to process your location.

c. Bluetooth

If the location determination is to be done with Bluetooth Beacons, the LiquidEarth app needs access to the Bluetooth function of your end device.

d. Media storage

If you want to upload data from your terminal device to our cloud environment, you need to allow the LiquidEarth app to access your end device's media storage.

6. Deletion of the data

Different retention periods apply to different types of personal data.

6.1 Technically necessary connection and location data

We only store the technically necessary connection and location data temporarily and the raw data is deleted after 14 working days.

6.2 Profile and login
