BIOLOCK Privacy

BIOLOCK PRIVACY POLICY

Effective Date: 25 May 2026 Last Updated: 28 May 2026

Yehudah Shilo Groskin ("Developer") operates the BIOLOCK mobile application (the "App") for iPhone and Apple Watch.

 

Quick links

 

The short version

BIOLOCK collects no data from you. The App contains no networking code. Nothing leaves your device. This is enforced at compile time, not by a policy promise.

 

Information the App reads

The App reads three signals locally on your device:

  1. Microphone audio — used only to compute the voice-coherence input V(t) in real time. Audio is not stored. Audio is not transmitted.

  2. Motion sensor data — read from CoreMotion to compute the motion-stability input ms(t). Motion data is not stored as raw samples. Motion data is not transmitted.

  3. Heart-rate variability — read from HealthKit to compute the HRV-coherence input hrvC(t). HRV data is read by the App at runtime and is not transmitted.

The computed steadiness score (PAS_bio) and the session summary (SessionRecord) are saved locally on your device as JSON files in the OS application sandbox.

 

Information the App does NOT collect

The App does not collect, store, or transmit:

  • Personal identifiers (no name, no email, no account)

  • Contact information

  • Location data

  • Browsing or search history

  • Advertising identifiers

  • Diagnostics or analytics

  • Raw audio recordings

  • Raw motion samples

  • Raw HRV samples beyond what's needed for real-time computation

 

How the App enforces "no transmission"

The App's source tree includes a compile-time build-phase script that fails the build if any of the following symbols appears in the Swift source:

import Network, URLSession, Socket, Stream, NSStream, HTTPClient, URLRequest, Firebase, CloudKit, AWS, Amplitude, Mixpanel

This means the App that you install from the App Store is the same App that was built — and that App has no way to send data anywhere.

In the App Store privacy nutrition label, all 14 data categories are set to "Data Not Collected."

 

Local storage

Session records are saved as JSON files in the OS application sandbox at:

~/Library/Application Support/BIOLOCK/{uuid}.json

These files contain the time series of the steadiness score, the drift derivative, and the corrective values for one session. They contain no personal identifiers.

When you delete the App, the OS deletes these files automatically.

 

Sharing

If you wish to share a session record with a third party (for example, a clinician or researcher), the App exposes a local file URL that you can pass to the iOS share sheet. The share sheet is provided by the operating system; the App itself does not perform the transmission. You initiate and authorize any such sharing.

 

Your rights

Because the App collects no personal data, there is nothing to access, delete, or opt out of beyond what the iOS Settings app already controls (HealthKit, Microphone, Motion & Fitness permissions, and on-device storage).

Children's privacy

The App is not directed to children under 13. The App collects no personal information from anyone, including children.

 

Changes to this policy

If this policy changes, the new version will be posted at this URL with a new "Last Updated" date. Because the App is shipped with no networking code, policy changes here cannot retroactively transmit your data — the App you installed cannot do so by construction.
