GradeFlow

Improve SmartSchool with grade overviews, weighted averages, period filters, chat, and arcade games.

PEER-TO-PEER CHAT - BETA (press F7) • Opt-in overlay chat with other GradeFlow users, fully off by default • Direct browser-to-browser over WebRTC, no server, no account • Host generates one invite link per friend (room code is baked in), share each link yourself (Discord, messages, etc.) • Each invite slot doubles as a kickable seat once someone connects • Rooms cap at 8 people (host + 7) • Survives page navigations on SmartSchool, the chat stays alive while you browse • Messages are kept in memory only (max 60, wiped when the room closes or the tab is closed). GradeFlow never writes chat to disk, but other people in the room can copy or save what you send. • Warning screen on first use: your IP is visible to every peer, there is no moderation, and any peer can pick any nickname and send anything. Only chat with people you actually know. • Fully translated (Dutch, English, French) • This feature is in beta. Connections may not work on school or corporate networks. Use with caution. KEYBOARD SHORTCUTS • F7 - open/close the chat overlay • F8 - open/close the arcade • Esc - close settings, arcade, or current game • P - pause game • R - restart game • Arrow keys / WASD - game controls • Z - rotate (GradeStack) PRIVACY GradeFlow reads your grades from SmartSchool's own API (you need to be logged in) and keeps everything locally in your browser. No grade data ever leaves your machine. No analytics, no tracking. The optional P2P chat connects directly between browsers using WebRTC and makes a single STUN request (Google's public STUN server) to establish the connection. No chat content is ever sent to us or any third-party server. See the full privacy policy for details.
