How your notes stay private.

When you create a note in Kilde, it is encrypted on your device using AES-256-GCM with a key that only you possess. The encrypted data is then transmitted to our servers in the EU. We store it. We cannot read it. We never will.

Algorithm: AES-256-GCM
Key Exchange: X25519 + Kyber-768 (hybrid post-quantum)
Authentication: Argon2id (memory-hard KDF)
Transport: TLS 1.3 (EU-terminated)
