Privacy Policy

Last updated: October 2026

1. Anonymous by Design

Joining as a player requires only a nickname and a session PIN. Zembil does not collect student email addresses, phone numbers, or persistent cross-session identifiers during gameplay.

2. Zero Proctoring & Surveillance

We strictly enforce an anti-surveillance guarantee: no webcam monitoring, microphone recording, keystroke biometrics, or lockdown browser integrations are ever used or permitted on our platform.

3. Multi-Tenant Isolation & Data Retention

Organization and institutional data is strictly partitioned using PostgreSQL Row-Level Security (RLS). Personal data subject requests (DSAR/GDPR/KVKK) allow automated erasure of user records while respecting statutory retention obligations.

4. What your organisation’s staff can see

If you join an organisation with your account — a school, a department, a team — the staff who run its classes and assignments can see your account’s display name next to your work, results and progress in that organisation. They do not see your activity in any other organisation. Someone who joins a live session with only a nickname is never shown by name.

5. Cookies

The cookies this site sets, what each one is for and how long it lasts are listed in our cookie policy.
