## What is Dark Bio?

Nothing happens to your Ark without your say-so. Ark Companion is the key to your Ark; pair once, and every unlock, every analysis, every access goes through you first.

Pairing is verified visually: a color sequence must match on both devices before a post-quantum encrypted link is established. From that point on, you are the gatekeeper.

  • Approve or deny every unlock with a hold-to-authorize gesture
  • Review third-party analysis tasks before they touch your data
  • Browse a tamper-evident audit journal of every device event
  • Get notified the moment your Ark needs attention
  • Lock the app behind Face ID or Touch ID

Your Ark encrypts your data locally, on hardware you physically hold. Ark Companion never sees, stores, or transmits that data. All communication is end-to-end encrypted through a zero-knowledge relay that cannot read your messages.

No account. No analytics. No tracking. Just you and your Ark.
