Cubbyed is the classical-education app built for the way real children actually learn — through repetition, primary sources, and teachers who care. A FULL CLASSICAL CURRICULUM, K–12 Lessons in mathematics, grammar, Latin, logic, history, rhetoric, literature, and natural philosophy. Every subject is taught the classical way: from first principles, with the great books, and a teacher (not an algorithm) in the loop. MATH AS PUZZLES, NOT TESTS The Math Puzzle Lab presents every problem as a drag-and-drop puzzle. Wooden tiles slide into cubby-shaped slots. Wrong pieces don't get a red X — they simply don't fit. Right pieces explain the rule they prove. The Five Universal Rules of Math (place value, the four operations, the commutative/associative/distributive properties, equation balance, and the inverse principle) are practiced to automaticity. The post-it-on-the-fridge promise: calculus before freshman year. AGE-AWARE COACHING Cubbyed knows whether it is talking to a 1st grader or a high-school senior. K–5 get Captain Cubby's "POW! Nailed it!" cheers. 6–8 get Coach Nova's "locked in." 9–12 get Professor Sage's "mastery pace." Every prompt, every reaction, calibrated to who is holding the device. FRESH LESSONS EVERY DAY An on-device AI agent generates a daily learning gem and a fresh full lesson for every grade band, every night. Nothing reaches a student until a teacher or parent has approved it. Every item is fact-checked by a second AI pass before review. The library does not get stale. CLASSICAL LIBRARY + READER Homer, Plato, Shakespeare, Euclid, Aristotle, Cicero, the U.S. Constitution, Common Sense, Pride and Prejudice — the great works, free forever. Built-in reader with bookmarks, page notes, Dark / Sepia / Light themes, and class-shared annotations. HISTORY CARDS A binder of digital baseball cards for the world's great figures — Socrates to MLK, with verified facts and primary-source quotes. Tap any card to flip it. KNOWLEDGE CONSTELLATION The K-through-calculus math curriculum rendered as a star map. A child can literally see calculus glowing at the bottom of the screen on day one — the path made visible. SAT & ACT PREP — BUILT RIGHT IN Ten focused minutes a day, starting in 7th grade. By test day a student has accumulated hundreds of practice questions, real test-taking strategies, and genuine content mastery. No separate course. No extra cost. SAFETY AND SECURITY — ARCHITECTURE, NOT MARKETING Default-deny database rules. Owner-only profile access. No student-to-student messaging. No advertising. No behavioral tracking. No data brokers. TLS 1.3 + HSTS preload. Apple In-App Purchase on iOS — Cubbyed never sees a card number. FERPA-aligned, COPPA-compliant design. Full policy at https://cubbyed.com/security. FAMILY CUBBY Optional subscription for up to four students per family. Monthly or annual, with Family Sharing on. Cancel any time in Settings.
