About Jap!

Jap! is a lightweight credential management and autofill extension designed for schools, computer labs, classrooms and other shared-device environments. Admins can create Local or Sync Workspaces, import credential lists by CSV or paste directly from spreadsheet applications, search and autofill credentials, and manage Reader access without requiring users to create a Jap! account. Local mode works entirely on the device and is free to use. Local Reader Mode allows a shared computer to provide controlled search and autofill access while administrative functions remain protected by the Admin's Master Password. Jap! Sync is an optional lifetime upgrade that enables encrypted credential synchronization between Admin and Reader devices using a Sync Code. It also provides Broadcast announcements, Reader Inbox, domain-only Activity monitoring and Class Session management. During a Class Session, Admins can view online Readers, assign accounts to specific computers, organize Readers using custom names such as PC 1 or PC 2, search Readers, filter accounts by class or tags, and remotely request credential autofill on assigned Reader devices. Remote Fill uses credentials already available in the Reader's synchronized Jap! data and does not transmit plaintext passwords through the realtime command channel. Admins can also send Personal Alerts to one Reader, selected Readers or all online Readers. A Personal Alert displays a blocking notification over supported webpages and requires the Reader to acknowledge it before continuing. The End Class feature helps protect shared computers after a session by allowing an Admin to remove relevant website login-session data from connected Reader devices, reducing the risk of accounts remaining signed in after class. Jap! Sync supports up to 3 Admin devices and up to 5 Sync Workspaces per lifetime license. Reader access is free. Credential synchronization data is encrypted client-side before being stored on the backend. Activity and Class Session status use limited information such as the Reader device identifier, custom Reader name, current domain and last-seen or online status. Jap! does not collect full URL paths or queries, page content, screenshots, keystrokes or detailed browsing-history logs. Jap! is available in English and Bahasa Melayu.
