Classy Apps
Apps designed with simplicity, ease and without collecting data
Welcome! These apps are built for students, teachers, and makers: anyone who loves to dream up ideas and bring them to life. Each tool is designed to help you through the design process, from brainstorming and sketching to planning, building, and refining. Every app is completely free and open source, so you’re welcome to explore the code, learn from it, or make it your own. They run right in your web browser with nothing to install, or you can download them and run them locally on your own computer, even without an internet connection. Your privacy matters: these apps collect zero data and send zero data. Your work stays yours, on your device, always. So jump in, experiment, and have fun creating!
