Ontracker
OnTracker is a free daily email brief for Deakin University students on OnTrack. It runs every weekday morning and tells you exactly what's overdue, what to work on next, and what your tutor has said without you having to log in or check anything. Install it once, and it just shows up.

About
What we built.
The full story behind Ontracker.
A full-stack student productivity tool, an MV3 Chrome extension paired with a Flask + PostgreSQL backend running thousands of individualised APScheduler jobs that email each user a daily task brief via Resend. Solved a rotating-token auth problem: OnTrack issues a fresh token on every API response, so the extension continuously captures the latest token from the browser and pushes it (encrypted at rest) to the backend, keeping scheduled briefs running unattended. Integrated Clerk for single sign-on identity and deployed on Railway with a Docker-based local dev stack.
