Hourmark

See where your study time went.

Hourmark is a local-first Chrome extension that helps students track study time by course and task, and see where their browser time actually went during a study session. - Count-up timer that measures the work you put in, not a countdown to a break. Timing survives closing the popup or restarting the browser. - Every session belongs to a course, and optionally a task, so your hours stay attached to real coursework. - See which websites your study time went to — recorded only while a session is running, never in the background. - Manual time entry for offline reading, handwriting, or study groups. - Search, filter, and correct your session history. Export to CSV or a full JSON backup at any time. - Everything is stored on your device. No account, no sign-in, no sync, no ads, nothing sold. Read exactly what's collected and why in the privacy policy. Study effort, made visible.
