Limits are per day and reset at midnight UTC. Only what Claude writes for you counts: a new lesson (or the rest of one that stopped partway), messages, course plans and graded answers. Rereading a finished lesson, your library and syncing never do.
Payment and sales tax are handled by Polar. Cancel any time from You → Manage billing; Pro lasts to the end of the period you paid for.
