LockSeed Lite - Protect Your Crypto Seeds Without Storing Them Your crypto wallet seed phrase is the master key to your digital assets. But where do you keep 12 or 24 words safely? - Paper can burn, get wet, or be found - Digital files can be hacked or leaked - Cloud storage means trusting third parties - Password managers can be breached LockSeed takes a completely different approach: YOUR REAL SEED IS NEVER STORED. Not on your device. Not on any server. Nowhere. HOW IT WORKS 1. Enter your 12 or 24-word seed phrase 2. Create a personal phrase you'll never forget (a song, poem, prayer, or any memorable text) 3. LockSeed generates a scrambled list of 26 or 52 words 4. Your real seed words are hidden among decoy words at specific positions 5. Only your personal phrase can reveal the original seed Even if someone finds your word list, they cannot extract your seed without your personal phrase. The list is useless on its own. 100% OFFLINE - ZERO DATA COLLECTION - Works completely without internet - No data sent anywhere, ever - No cloud storage or sync - No accounts, no registration, no tracking - Everything stays exclusively on YOUR device ADVANCED SECURITY - Real seed is never saved to storage - PIN protection with PBKDF2-HMAC-SHA256 (100,000 iterations) - Brute force protection with progressive delays - Sensitive data cleared from memory after use - No keyboard suggestions on sensitive fields - Session timeout with automatic lock - Clipboard auto-clear after copying addresses - Passphrase strength indicator - Face ID / Touch ID support GUIDED EXPERIENCE - Interactive onboarding tutorial on first launch - BIP39 auto-complete when typing seed words - Automatic language detection (English, Portuguese, Spanish, Hebrew) - Built-in help and manual LITE VERSION INCLUDES - Up to 2 wallets - Up to 3 crypto addresses per wallet - Full encode/decode algorithm (same as Premium) - Manage crypto addresses with QR codes - All 4 languages - All security features SUPPORTS ALL BIP39 WALLETS Works with Bitcoin, Ethereum, Solana, Polygon, BNB Chain, Tron, and any wallet that uses the BIP39 standard (2,048 words).
