Why does the app need an account?
Signing in comes first, with Google or an email link. It is what gives AI features their monthly credits and, on Pro or the trial, syncs your Canvas data, notes and study material, encrypted, to every device you sign in on. On Free, sync pauses.
The server holds your identity, plan, credits and calendar feed, never the coursework itself.
What does Pro change?
250 AI credits a month instead of 3, background sync every 30 minutes, every course on your calendar feed instead of 2, and encrypted sync across every device, course files included.
The calendar, the planner, notes, decks and quizzes work the same on both.
How do I cancel?
Settings, Account, Manage billing. Pro runs to the end of the period you paid for, then the account drops to Free. Semester, notes and decks are untouched either way.
Does my data follow me to another computer?
Only Canvas needs the extension, and only on one computer. Notes, decks, quizzes and the study plan follow you the moment you sign in on Pro or the trial. No code to enter, no separate step.
A phone or an iPad cannot run the extension. Sign in there too, and the semester appears once Canvas is connected on a computer with Chrome.
How does syncing across devices work?
It follows your account. Sign in with Google or an email link on Pro or the 14-day trial, and every device you sign in on after that stays in sync. No code, no QR, no phrase to keep.
Notes and study material are encrypted before they leave the device, with a key stored with your account so any device you sign in on can open them. That means we hold the key. We do not read student data; access to keys is limited to the running service and every key read is logged. Canvas flows one way, from the computer running the extension out to your other devices.
Settings, Devices lists your devices, renames or unlinks one, and has a switch to pause sync on this device only.
