PRTCL
Local Brain

Your health data
never has to leave.

Your data never goes missing, and it is never anyone else's asset. PRTCL keeps every protocol, dose and reading in an encrypted database on your own device. Cloud sync is a choice you make, not a condition of using the app.

Encrypted at rest

Unreadable without you.

The local database is encrypted with SQLCipher. Without your device credential the file is unreadable — even to someone holding the phone.

  • Protocols, doses and history stored on the device
  • Encrypted database file, not a plain cache
  • Works fully offline
Sync is opt-in

Your call, every time.

Use PRTCL entirely offline if you want. Turn sync on and your protocols follow you to a new device; turn it off and they stop leaving.

  • Off is a real option, not a degraded mode
  • Move to a new phone without starting over
  • Switch it off whenever you like
Access log

An access log you can read.

Every read of your health data is written to a local audit log. When PRTCL for Clinics launches and you choose to share with a clinic, you will see exactly when they looked, and at what.

  • Every read, timestamped
  • Kept on your device, readable by you
  • Sharing is granted per category and revocable
App lock

Locked behind your face, print or PIN.

PRTCL locks itself the moment you leave it. Your fingerprint or face where your device supports them, a six-digit PIN where it does not, and no way in without one of them. A wrong attempt stays locked. Only you get the green light.

The business model

We would rather hold less of your data.

PRTCL does not sell health data, and there is no advertising business behind it. The subscription is the business model — the only arrangement that keeps both of those true.
