What each plan costs and what it does. The 30-day windows are spelled out below, not in fine print.
Your first 30 days after signup: unlimited study materials, flashcards, and quizzes, across as many semesters, quarters, or courses as you like. When that window closes, the calendar, sessions, and your study plan stay free — creating and opening study materials, flashcards, and quizzes stops.
Thirty days after a semester ends, that semester’s data is permanently deleted — no undo, no restore. You can export everything before then, free, on either plan. This is a separate clock from the 30-day access window, which runs from signup. Pro keeps every semester forever.
Pro is $10 a month, after the 30-day trial. Payment is handled by Stripe. If you're under 18, a parent or guardian completes the purchase.
Two taps, from Settings or any billing email — no phone calls, no chat with a retention bot. After you cancel, your calendar, sessions, and study plan stay free; study materials follow the Free plan’s rules from then on.
If a charge lands and you didn't mean it to, write to us within 30 days and we'll refund it. No forms to argue with.
