# Håck mas Castle 2026 Fahrplan (open-source calendar and contacts app)

> Håck mas Castle 2026 Fahrplan is a free, open-source calendar and contacts app for Android. Eine Fahrplan-App für Håck ma’s Castle 2026. It has 279 GitHub stars and is released under the Apache-2.0 license, and you can install it from F-Droid and Google Play.

Håck ma’s Castle ist ein offenes Schloss für alle Arten von Nerds. Wir wollen das Schloss als inklusiven Ort nutzen, als einen niederschwelligen Einstieg, um Wissen zu vermitteln und Erfahrungen auszutauschen. Håcken steht dabei für den kreativen Umgang mit Technik zum Beispiel bei Computern, Nähmaschinen, der Gesellschaft und Herdplatten (Essen ist wichtig!). Niemand soll sich aufgrund fehlenden Wissens, (bisher) fehlender Zugehörigkeit oder fehlender Erfahrung ausgeschlossen fühlen. Unser Schloss hat keine geheimen Türen – nur offene Räume, in denen man gemeinsam tüfteln, lernen und staunen kann.
