JLPT Vault is a high-performance, offline-first study engine designed for serious Japanese learners. Engineered for maximum operational efficiency, this app combines a sleek Glassmorphism interface with a battle-tested Spaced Repetition System (SRS) to drive your progression from N5 fundamentals to N1 fluency.

WHY THE VAULT? • 100% OFFLINE: Execute your study sessions anywhere—on the train, in the gym, or in the air. Zero internet connection required. • COMPREHENSIVE N5-N2 DATASET: Access a massive, curated database of vocabulary and multi-context grammar sentences spanning JLPT levels N5, N4, N3, and N2. • PRO-GRADE SRS: The logic engine tracks your memory retention for every single item, optimizing your study time by targeting exactly what you are about to forget. • DYNAMIC FURIGANA CONTROL: Toggle furigana visibility to force raw Kanji recognition. The system automatically adapts to your level, stripping basic N5/N4 furigana when studying N2 data to simulate real-world reading.

CORE ARCHITECTURE: • Multi-Tier Vault System: Switch seamlessly between your targeted N5, N4, N3, or N2 databases. • Interactive Study Arena: Utilize a four-tier memory rating protocol (Again, Hard, Good, Easy) for precise algorithmic feedback. • Granular Progress Tracking: Audit your mastery percentage across the entire JLPT spectrum. • Distraction-Free UI: Aesthetic, high-contrast visual design built to maintain hyper-focus during execution.
