VimNinja: Interactive Vim Tutorial and Game の個人情報保護方針
VimNinja collects nothing and sends nothing: the extension makes no network requests at all.
Your progress, settings and reminder times stay in the extension's own storage on your computer, apart from the vimninja.com website's, and uninstalling the extension removes them. Reminders are worked out on your computer from that progress. The extension asks to show notifications only when you choose a reminder, and never reads your tabs or the pages you visit.
