What is ClassGhost?
ClassGhost is a free, teacher-moderated anonymous classroom messaging platform built for students and educators. Students can post questions, feedback, and thoughts anonymously in a private, password-protected group — without fear of judgment.
ClassGhost is designed for educational use only. Every group is private and requires a password to join. Teachers are the group admins and have full moderation control. All messages auto-delete after 24 hours.
Is ClassGhost Safe? (Safety & Moderation)
ClassGhost is built with classroom safety as a core design principle:
- Private groups only — no public boards, no anonymous public access. Students must have a teacher-shared password to join.
- Teacher moderation — the group admin (typically the teacher) can delete any message instantly at any time.
- 24-hour auto-delete — all messages disappear after 24 hours automatically, preventing long-term harm.
- Rate limiting — maximum 5 messages per minute to prevent spam or flooding.
- No personal data — no names, emails, or IP addresses are ever stored. Nothing to expose.
- Password rotation — admins can change the group password at any time to remove access from the group.
These design choices make ClassGhost fundamentally different from open anonymous platforms. ClassGhost is a private classroom tool, not a public anonymous network.

How ClassGhost Works
- Teacher creates a group — chooses a custom Group ID (like MATH101), an admin password (private), and a member password (shared with class).
- Students join — enter the Group ID and member password. No account, no email. Done.
- Post anonymously — messages arrive as sealed envelopes. Students tap to reveal. No names attached.
- Auto-cleanup — everything disappears after 24 hours. The board resets itself daily.
