    How the ACC app works:

    The app used by the user clearly shows the messages that the ACC developed by us sends to the end devices. The message to the ACC app web service in the cloud (Azure cloud is hosted and hosted by us through an interface (ACC channel)) administered / used). This ACC app web service is necessary to send push notifications to the end device. The end device can then download the message from the ACC app web service and display it in the ACC app. For more information on this and on the complete range of functions, go to The message can then be accepted or rejected via the app (feedback to the ACC app web service and thus to the ACC). In addition, there are other functions such as "Set participant status" to interact directly with the ACC (or the ACC app web service). The content of the ACC database is updated here.

    Localization of the processing processes of used data:

    The data processing takes place via two servers, the ACC server, which is operated by the user, and the above-mentioned cloud server (ACC app web service). The data of the messages (message text, times, etc.) are then on the cloud server.

    Type of the user's personal data processed by the app:

    • User name of the user (ID or telephone number)
    • the user's personal password (encrypted storage)
    • other app-specific, individual settings of the user, e.g. ringtone setting
    • Information or messages transmitted by the ACC to the user (message text, status of the message, etc.)

    Evaluations of the user's personal data processed by the app:

    We do not evaluate the personal data processed by the app (for example: individual usage analyzes, determination of score values, etc.). The user receives (only) the information that he has requested in processed form. There is the possibility of submitting a support request and the data already described above will be sent to ACC support by e-mail.

    Securing the user's personal data:

    The data backup is always based on the state of the art with current backup systems:

    • In the app: In a database (SQLite) and in the internal app storage
    • In the ACC app web service: in a database of the Microsoft SQL server

    Deletion of the user's personal data:

    The user can manually delete the messages in the ACC app. Depending on the setting, the messages can be saved for a maximum of 99 days. Data such as the user name, password and settings of the user are stored until the user account is deleted. A deletion occurs when the employee no longer works for the company or should no longer be alerted by the ACC. If the app is uninstalled from the smartphone, the personal data are also deleted, but they are still available in the ACC app web service. All personal data processed with the use of the ACC app will be deleted after the statutory, in particular tax retention periods have expired.
