CryptKeeper is 100% non-custodial. Your seed phrase is generated locally using BIP39 standards and encrypted with AES-GCM (PBKDF2, 310,000 iterations, SHA-256). Private keys never leave your device and are never transmitted to any server.

Unlike custodial wallets where a third party holds your keys, CryptKeeper ensures you retain full ownership and control of your digital assets. All transactions are signed locally on your device before being broadcast to the blockchain.
