EtherPK Sync Server
Your encrypted knowledge, synced across your devices.
EtherPK runs this server for Sync+. Your devices encrypt your notes before they arrive, so it stores only what it cannot read.
Stores only ciphertext
Your devices encrypt every change, snapshot and file before it arrives. The server keeps them without the keys to read them.
Protected sign-in
Passkeys and two-factor authentication guard your account, and the keys to your graphs never leave your devices.
Recovery without exposure
Device Approval and your Recovery Code let a new device in. The server keeps only encrypted key material.
