Dark Bio: Ark Companion

Dark Bio AG

About this app

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.

• Hold to approve unlocks, updates, upload, app and reports
• Browse your Ark's tamper-evident journal of every device event
• Review third-party analysis apps before they touch your data
• Review every report before it is released back to your computer
• Save reports on your phone, encrypted and out of your backups
• Manage all your Arks, physical and emulated, in one app
• Get notified the moment your Ark needs attention
• Lock the app behind face or fingerprint unlock

Your data stays on your Ark, encrypted and in your hands. Ark Companion only ever sees app reports, never your raw data. All communication is post-quantum end-to-end encrypted through a zero-knowledge relay.

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