MathBoard is provided as an iPhone and iPad mental-arithmetic worksheet and whiteboard practice app for personal and educational use. Use of MathBoard is also subject to Apple's standard End User License Agreement (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/.
1. Use of the app
You may use MathBoard and its included content for personal, non-commercial learning and practice. A parent, guardian, or teacher should guide young children. Do not reverse engineer, redistribute, resell, or misuse the app or its assets.
2. Local data and drafts
MathBoard saves local preferences, worksheets, practice attempts, wrong answers, and PencilKit whiteboard drafts. Local data can be lost if the app is deleted or device data is erased; keep copies of any worksheet PDFs you want to retain.
3. Optional purchases
MathBoard may offer optional in-app purchases for Pro: a Monthly or Yearly auto-renewable subscription, or a one-time Lifetime purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Purchases are processed by Apple through StoreKit. Refunds, cancellations, billing issues, and purchase account management are handled by Apple.
4. Free and Pro features
Core practice is entirely free — all problem types, number ranges, and set sizes are available without paying. Pro unlocks PDF export (question/answer/wrong-answer walkthrough editions), full step-by-step explanations with vertical and visual models, wrong-question drills with per-skill mastery, learning reports (weekly/monthly trends and weak areas), and batch generation with unlimited worksheets.
5. Educational accuracy
MathBoard generates problems and grades answers using deterministic local rules, and worked explanations are generated to support learning. Always supervise young children and verify important results independently.
6. Availability
Features may change as the app is improved. We aim to preserve purchased Pro access for the Apple ID used for purchase, subject to Apple platform behavior and StoreKit availability.
