Built to be auditable. Open source, end‑to‑end encrypted.

Aplexica's security model is documented and the source is public. Read what we do, what we don't, and how to report a vulnerability.

Four security pillars.

  • 01

    Open source daemon

    What runs on your machine is what is in the repo. Build it yourself if you prefer.

  • 02

    Zero-knowledge cloud

    XChaCha20-Poly1305 over a per-namespace key. Keys never leave your devices; Aplexica cannot read your content.

  • 03

    Customer-managed keys

    Enterprise can supply their own KMS-rooted keys. Aplexica becomes a transport that has no decryption capability.

  • 04

    Audit by default

    Every artifact change is signed and chained. Tamper-evident logs are exportable to your SIEM.

Your machine is the trust boundary.

The Open Source daemon makes zero network calls in its default configuration. When you opt into Cloud, sync uses XChaCha20-Poly1305 for content and X25519 + Ed25519 for transport. Keys are generated and stored on your devices. Aplexica's servers see only ciphertext.
