With the app, students, parents or teachers can view the substitution plan on the Untis website. The app is therefore only a "viewer" of the Untis website on an Android device.

The Untis login data can be entered in the configuration in advance. A pre-selection of the year and class is also possible. The display of the substitution plan is then filtered accordingly.

The display of the current day and the following day is not done by automatic switching as on the website, but by the selection of tabs.

Since the app - just like an Internet browser - is only a display of external data, no guarantee can be given for the correctness of the data. The filter function of the year and class also depends on the content and the accuracy is not guaranteed.

No data is collected. The entered login data are also only stored locally (but not separately encrypted) and only transmitted to the Untis website for login. However, possible evaluations on the part of the website provider (Untis) are beyond the control of the app.
