Privacy & Data Collection in LockDown Browser on Mac
What LockDown Browser sees and what Respondus Monitor records are different. LDB alone reads the active exam window, the running-process list, and basic system identifiers. Monitor adds webcam, microphone, and periodic screenshots, uploaded to Respondus servers for instructor review. Several U.S. universities have restricted or banned remote proctoring; class-action lawsuits in 2021-2024 have alleged Fourth Amendment violations.
What LDB and Respondus Monitor actually access on Mac
The two products have different data-access profiles. Treat them separately when evaluating privacy:
| Resource on your Mac | LDB alone | + Respondus Monitor |
|---|---|---|
| Active exam window content | Yes (kiosk-mode rendering) | Yes |
| Other Safari tabs | Blocked from rendering during exam | Same |
| Documents folder, iCloud Drive, Time Machine | No access | No access |
| Browser history, autofill, passwords | No access | No access |
| Running process list | Yes (blacklist enforcement) | Yes |
| System info: hostname, OS version, hardware UUID | Yes (telemetry) | Yes |
| Network endpoints contacted | respondus.com, blackboard.com (varies by LMS), institution endpoints | Same + Monitor video upload |
| Webcam stream | Not accessed | Recorded for exam duration |
| Microphone audio | Not accessed | Recorded for exam duration |
| Screen recording (entire screen) | Periodic frames (kiosk-mode enforcement) | Same + uploaded |
| Files outside the exam window | No access | No access - recordings are screen frames, not file system |

Class-action lawsuits and university bans timeline
The legal and policy context around remote proctoring on Mac (and elsewhere) has been actively contested since 2020. Major events:
- 2020-2021. COVID-19 pushed proctoring adoption to record highs. EFF published "Proctoring Tools and Dragnet Investigations Rip the Throat Out of Student Privacy" (Aug 2020). Multiple petitions circulated at universities.
- 2022. Cleveland State University sued in Ogletree v. Cleveland State; Northern District of Ohio ruled the room-scan portion of a Respondus Monitor exam violates the Fourth Amendment.
- 2022-2023. Yale Law School moved to in-person final exams. UIUC and Cleveland State restricted room scans.
- 2024. Settlements in some cases. Continued use at most large universities. Coverage of accessibility issues - facial-detection underperforms on darker skin tones.
- 2025-2026. Several universities adopted "Respondus Monitor only with student consent" policies; some allow opt-out for in-person.
