Support

Contact

Email emtrack2026@outlook.com. Include your interface language, Chrome and extension versions, time of the issue and steps to reproduce it. Do not send passwords, invitation links, session credentials, student contacts or lesson files. Redact personal data from screenshots. Support is handled manually; no 24/7 response or fixed response time is promised.

Connection and invitations

Check your connection and reopen the board after the server is available. Do not treat unacknowledged actions made during a lost connection as saved. Ask the teacher for a new invitation if access has ended. Only the teacher can change invitation permissions or revoke access.

Limits

A teacher account includes 30 MiB for boards and cabinet records. A PDF can be up to 25 MiB and 100 pages; an inserted image up to 2 MiB. Delete unneeded materials or contact support about additional storage. Extensions and student browser clients need the server for shared access; unlimited concurrent lessons or uninterrupted service are not guaranteed.

For forgotten passwords or account deletion, follow the account procedure. For a suspected leak, stop sharing the invitation, revoke it and contact support privately. Do not publish security details with real access links.
