Lion's Legacy - Offline Vault

Lion's Legacy is the offline vault app that never touches the cloud. Cards, bank accounts, identity documents, passwords, private notes, and a digital legacy planner — all encrypted on your phone with AES-256, HMAC-SHA256, and PBKDF2 at 200,000 iterations. The app does not request the network permission. Your data never leaves your device.

🔐 SECURITY YOU CAN VERIFY • AES-256-CBC with HMAC-SHA256 (encrypt-then-MAC) • PBKDF2-HMAC-SHA256 with 200,000 iterations • Hardware-backed keys in the Android Keystore • Encrypted SQLite database (SQLCipher) • Biometric unlock plus 6-digit PIN • FLAG_SECURE blocks app-switcher screenshots • Pure-Dart crypto core, no third-party crypto dependencies • 130+ unit tests for crypto and storage paths

🏛️ DIGITAL LEGACY PLANNER WITH SPLIT-KNOWLEDGE RECOVERY • Emergency contacts (doctor, lawyer, executor, next of kin) • Final wishes for funeral, medical, legal, financial, personal messages • Document locations (bank locker, home safe, lawyer's office) • Wellness check-in with a configurable grace period • Split-knowledge recovery — neither LionScripts nor your contact can access the vault alone

💾 TRIPLE-ENCRYPTED .lionlocker BACKUPS • Single file survives any device loss • Protected by passphrase, backup token, and integrity hash • Restore on any device — no cloud, no account, no recovery email

🚫 WHAT WE DO NOT DO • No internet permission — ever • No accounts, no sign-up, no recovery email • No analytics, no telemetry, no crash reporting, no third-party SDKs • No ads, no banners, no nags • No data leaves your device unless you export a backup yourself

🆚 ALTERNATIVE TO 1PASSWORD, LASTPASS, ICLOUD KEYCHAIN Most vault apps upload your data and promise it's safe. Lion's Legacy takes the opposite stance. Even if we get hacked tomorrow, the worst case is our marketing site goes offline. None of your data is ever in our hands.

🎨 PREMIUM EXPERIENCE • Material 3 light, dark, and system themes • Realistic virtual cards with EMV chip visualization • Customizable swipe actions • CSV import and export • 12-page interactive onboarding with sample data
