The JusProg e.V. app for Android does not collect any personal data to be transmitted to JusProg e.V. or third parties. Parents create profiles for themselves and their children and can freely assign user names and passwords as well as age groups to the children. This data is only stored in the app and is not accessible to JusProg or other third parties.
For the functionality of the Android youth protection programme, it is unavoidable that when a user (child) calls up a website, the app transmits the domain called up and the age level in real time to a JusProg server (location: Germany) in order to receive information from there as to whether the website should be displayed or blocked for the age level. This data exchange is encrypted. No surfing logs or IP addresses are stored on the server and for statistical reasons (to improve the filter list), data on the frequency with which websites are called up is only recorded cumulatively; it is not technically possible to calculate back to an individual user.
When a website is called up, the app attempts to retrieve information on age classification under the same domain; this is usually done by calling up domain.tld/age-de.xml and domain.tld./age.xml. These calls are made anonymously without any personal information about the user. Technically, IP addresses are always transmitted with calls on the internet, even when calling up normal websites.
Accessibility Service API
Our JusProg child protection app uses the Accessibility Service API of the Android operating system. This API (internal interface) allows us to control screen access. We use this to prevent children from accessing the settings so they cannot simply turn off the app. Personal data is not read out via the Accessibility Service API.
Connection with the JusProgManager
The app works as an internal VPN, another VPN cannot be used in parallel. For function and bypass security, the app must be authorised (via AccessibilityService API) to “lock screen”, restrict access to the “settings”, be activated as a “service” as well as a “device administrator” and the “Private DNS” must be set to “Off”. It is recommended to switch off the “optimisation of battery power” for the app.
No personal data is collected, forwarded or stored via the AccessibilityService API.
