Local-area-network file & message transfer between Android phone and any browser.

Capabilities Two-way transfer: text and files move between Android and the browser over HTTP and WebSocket, with progress and failure states for both directions. The browser accepts drag-and-drop file uploads. Images and videos show proportional thumbnails in bubbles, with an in-app preview on Android and a fullscreen lightbox in the browser. Session history: Room-backed sessions support search, pin, rename, grouping, per-message actions, configurable retention, and crash recovery. Recall and cleanup: messages can be recalled during an active session, optionally including the other end's messages; local history items and sessions can be deleted with confirmation or undo where appropriate. Deleting a file frees its on-disk copy while History keeps an inert record. Files overview: browse files from all sessions in one place with direction/category filters, search, sorting, and multi-select actions (favorite, save, share, jump to message, delete). Favorites: keep independent text or file snapshots in collections, add local items without a session, search them, and send them back into an active transfer. Portable archives: export sessions, favorites, settings, or all data to a ZIP archive; save it on Android or serve it to a browser, then import it later. When imported sessions already exist locally, choose to skip or overwrite them. Adaptive appearance: Material 3 Expressive themes, custom theme color, dark mode, contrast, motion speed, avatars (including a browser-side avatar), bubble shape, grouping, and selected appearance settings stay aligned across phone and browser. Multilingual: both the app and the browser client support Chinese and English, and the language setting stays in sync across both ends. Offline browser client: the HTML, CSS, JavaScript, mdui components, Material Symbols font, and design tokens are bundled in the APK; no CDN is used.
