Privacy and retention by design
- Profiles are numbers only, with consent, kept 12 months; captures are kept 180 days.
- Internet addresses are stored only as one-way hashes, and Bluetooth records device types only.
Students and instructors should be able to understand what is stored and why. ExamLock distinguishes numerical identity profiles from evidence captured after escalation, limits evidence access, and offers a minors mode that stores no images, audio, or video.
Instructors see only their own students. Evidence is served through short-lived access links.
