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.

• Interactive Study Arena: Utilize a four-tier memory rating protocol (Again, Hard, Good, Easy) for precise algorithmic feedback.
