A lot or a little?
Parents need to know that Hopscotch: Learn to Code Through Creativity is a drag-and-drop programming app for kids to write their own programs plus a community for sharing creations, playing or remixing others' creations, and commenting on and supporting other programmers. The app is free to use, but a monthly subscription unlocks features including the option to add your own images and customize profiles. To register, kids set a username and password and give an email address (a parent's email for kids under 13). The privacy policy spells out how information collected could be shared and explains how to opt out (by uninstalling the app).
