What we see.
What we never do.
Plain language, no lawyer-speak. Hand this page to any parent. A tutoring organisation may copy it onto their own letterhead.
What ClassLume is
ClassLume lets a teacher see, during a live class, a small preview of the screen each student chooses to share — the same awareness a teacher has walking around a physical classroom. It is a visibility tool, not a recording tool.
What is captured
Only the single browser tab or window the student explicitly selects. A low-resolution still image is taken roughly every 3 seconds and shown to their teacher during the session.
What is never captured
No microphone. No camera. No keystrokes. No video recording. Nothing outside the one tab the student picked — not their other tabs, files, or desktop.
How long anything lives
Each snapshot is held in temporary memory and automatically deleted after 60 seconds. Snapshots are never written to disk and never used to train any model. Only a brief activity log (joined, idle, asked for help) is kept, for up to 30 days, so a teacher can review the session.
The student is always in control
The student chooses what to share and sees a constant “sharing with your teacher” indicator. They can stop sharing at any moment with one click — instantly and without asking.
Anonymous classes record nothing
If a class is run without a teacher account, no activity log is written at all — snapshots still expire in 60 seconds and nothing persists anywhere.
Questions
A parent or guardian may ask the tutoring organisation to exclude their child from screen sharing at any time, with no penalty to the student.
