The questions, explanations and flashcards are stored in the app, and your study progress stays on your device. YOUR DATA AND THE AI FEATURES The AI Tutor, the College Counselor and Scan & Solve send what you ask to AI services run by other companies: Google Gemini, with Anthropic Claude as a backup, through our server. Depending on the request, that is your message and the earlier messages in that chat; the question and its passage, the answer choices, the answer you chose, the correct answer and whether you got it right; for a question you are reviewing, its explanation and how many times you missed it; for a flashcard, the card and your pick; in the College Counselor, a short study summary (your score estimate and section ranges, goal score, number of practice sessions and how many colleges match) and the app's data on colleges you name; and in Scan & Solve, the photo you take. We don't include your name, email address or a device identifier. The app asks before it sends anything for the first time, and you can turn this off in Settings. Practice questions, flashcards and tests work without it. We use Tenjin to measure which of our ads lead to installs and subscriptions. The app works the same whether or not you allow tracking. FREE AND PREMIUM Free: a 5-question practice session a day for Math and one for Reading & Writing, a 10-card flashcard session a day, 3 AI messages a day shared by the AI Tutor and the College Counselor, accuracy by section, and one practice test. Premium removes the daily practice and flashcard limits and adds AI messages with no daily cap (fair use applies, and AI help can pause when demand is very high), more practice tests, and every feature marked Premium above. SUBSCRIPTIONS Premium comes as Monthly and Annual auto-renewing subscriptions. If your Apple Account is eligible for Apple's introductory offer, Premium starts with a 7-day free trial; the subscription screen shows whether a trial applies to you. Payment is charged to your Apple Account when you confirm the purchase or, if a free trial applies, when the trial ends. A subscription renews automatically unless it is canceled at least 24 hours before the end of the current period. Manage or cancel it in Settings > your name > Subscriptions.
