Privacy by design. We store only cryptographic hashes of your public key — never the key itself. We use memory-hard scrypt hashing (N=16384). Feature configurations are NIP-44 encrypted and only decrypted during processing of an incoming e-mail. No plaintext personal data is persisted.
No analytics, no cookies, no tracking. This page loads no external resources — all libraries (NIP-44 crypto, scrypt-js) are self-hosted. Nothing leaves your browser until you choose to purchase.
