Import & backup
Pull in a school or team calendar, or save a copy of everything.
From a calendar link
Canvas, Google Calendar, and most team sites offer a subscription URL ending in.ics. webcal:// links work too.
From a file
Downloaded an .ics export? Drop it here — it's read entirely in your browser.
Start a new term
Pick the day your last term ended and anything due before it drops out of the Work and To-do lists. Nothing is deleted — it stays in your backups, and your XP, streak and badges are untouched, because those are worked out from what you finished rather than from the lists. Each page says how much it's holding back and can show it again in a click.
Tidy up
No duplicates found — every assignment, activity, and scheduled event is unique.
Backup
Study Hall keeps everything in this browser under study-hall:v1. Clearing site data wipes it, so export a copy before you switch browsers or machines.
