- Detailed status: docs/MAJOR_SCAN_2026-02-28.md and docs/DEPLOYMENT_RUNBOOK.md.
The project started from a simple student pain point: repetitive downloads in Google Classroom.
What began as sketches on paper turned into a production extension used across multiple browsers and operating systems.
The original system idea started in a university lecture as handwritten architecture notes, then moved into iterative builds and testing. View the original handwritten system sketch.
- V1: Native JavaScript prototype.
- Modern CQD: WXT + React extension with an edge + backend analytics stack.
Peer feedback confirmed the same pattern: manual downloading is slow, especially near exams when file volume spikes.
Make downloading class materials boringly easy, so students spend time learning, not clicking.

CQD is built to avoid personal tracking.
| ✅ We Collect | ❌ We Never Collect |
|---|---|
| File type + status (success/fail/cancelled) | File contents |
| Browser + OS | Names/emails |
| Country-level usage (derived at edge) | Passwords/Google credentials |
| Performance/health metrics | Personal browsing history |

Yes. CQD is intentionally focused on classroom.google.com workflows.
No. CQD does not collect file contents, passwords, or personal account identity.
Cancellation analytics are highly accurate overall, but extremely fast near-cancel actions right after clicking download can be undercounted due to browser timing races.
CQD is also backed by a distributed reliability pipeline, but the deep engineering docs are split by module for easier reading:
