HIDDEN CODES ist ein Mobile Game der Bildungsstätte Anne Frank und widmet sich dem Thema Radikalisierung im Netz. In einer simulierten Social Media-Umgebung chatten die Spieler*innen, durchstöbern Profile und reagieren auf Storys und Kommentare anderer Nutzer*innen. Die App befähigt junge Menschen spielerisch dazu, problematische Inhalte oder Aussagen zu erkennen und kompetent darauf zu reagieren: Wie nutzen radikale Gruppen digitale Medien, um zu für ihre Zwecke zu mobilisieren? Welche politischen Codes und Verschwörungsmythen werden im Netz verbreitet? Was kann ich tun, wenn ich mitbekomme, dass sich jemand in meinem Umfeld radikalisiert? Spezifische Themen und Elemente rechter und islamistischer Radikalisierung werden in einzelnen Episoden beleuchtet.

Ogmntd brings paper to life: point the camera at a worksheet, a drawing or a poster – and a video plays right there, in perspective and with sound. FOR STUDENTS • Open the app, scan the channel's QR code, done – no account, no sign-in. • Point the camera at the worksheet and the explainer video appears on the paper. • Works offline too: videos are saved on the device. FOR TEACHERS • Sign in with your school's own Nextcloud – your password is only entered on the Nextcloud page. • Create channels and print the channel card with its QR code, or put it right on the worksheet. • Photograph a trigger image: a live meter shows whether it will be recognized well. Sheets photographed at an angle are straightened automatically. • Record a video or pick one from your library, then place, rotate, scale and tilt it on the real sheet with simple gestures. • Remove green screen backgrounds with an eyedropper – so an explainer character can stand right on the worksheet. • Three playback modes: on the sheet, anchored in the room, or full screen. • Large videos are compressed and uploaded in chunks. On poor Wi-Fi, uploads resume automatically later. PRIVACY • No tracking, no analytics, no ads, no third-party SDKs. • All content is stored only on your school's Nextcloud – never with us. • Camera images are processed on the device only and are never saved or transmitted. Ogmntd runs on iPhone and iPad with iOS 17 or later. Creating content requires a Nextcloud; viewing only needs a channel's QR code.
