Local credential autofill with encrypted Reader sync, broadcast inbox and domain-only activity. Jap! is a lightweight credential autofill extension designed for schools, computer labs, classrooms and shared-device environments. Admins can create Local or Sync Workspaces, import account lists, search and autofill credentials, and manage Reader access without requiring users to create a Jap! account. Local mode works entirely on the Admin device and is free to use. Jap! Sync is an optional lifetime upgrade that enables encrypted Reader synchronization, Broadcast announcements, Reader Inbox and domain-only Activity monitoring. Reader devices can connect using a Sync Code and use permitted autofill features without signing in. Jap! Sync supports up to 3 Admin devices and up to 5 Sync Workspaces per lifetime license. Reader access is free. Sync data is encrypted client-side before being stored on the backend. Activity monitoring records only the current domain and last-seen status — not full URLs, page content, screenshots, keystrokes or browsing history. Jap! is available in English and Bahasa Melayu.
