SecureDisplay Privacy Policy

Summary

SecureDisplay is a local-first tool that processes display and input data between nearby devices that the user explicitly authenticates. No account is required. Display pixels, keyboard input, pointer input and raw camera frames are not uploaded to Peaceful Journey servers.

We do not sell personal data or track users across other companies' apps or websites. The current app does not include advertising, behavioral analytics, session replay, or remote crash-reporting SDKs.

Local Display And Input Data

When the host Mac captures a display selected by the user, the display data is compressed and encrypted in memory for delivery to an authenticated receiver. If mobile touch input is enabled, pointer movement, left-click and drag data for that receiver's display is sent to the host over the encrypted connection.

This display and input data is not stored on Peaceful Journey servers or associated with an account. Active input and video session state is ended when the connection closes or the app or display becomes inactive.

Device Discovery, Authentication And Local Storage

To discover and directly connect nearby devices, SecureDisplay may process device names, app roles, network addresses, capabilities, and temporary connection identifiers on the local network. The six-digit code shown by the receiver is used only for verification; the code itself is not sent over the network or written to logs.

SecureDisplay stores an approved device ID and public identity key in each device's Keychain so that later connections can detect an unexpected identity change. Display layout, transport policy, quality, display mode and user-selected input settings may remain in local app storage. The in-app trust reset removes stored peer trust. Removing the app deletes ordinary app-container settings; using the in-app reset first is the most reliable way to remove app-created Keychain trust records.

Permissions

• Screen Recording: used by the host Mac to send a user-selected display to a receiver.
• Local Network: used to discover nearby receivers and open authenticated display and control connections.
• Accessibility: used to perform pointer clicks and drags on the host Mac only when the user enables mobile touch input.
• Camera: used only after the user starts automatic display-layout calibration and approves each camera round.

Declining a permission disables the related feature. Permissions can be changed in macOS, iOS or iPadOS system settings.

Camera-Based Display Calibration

Calibration analyzes screen-corner markers from rear-camera frames on the device. Raw photos or video are not sent over the network, saved to files, or added to the Photos library. Only results such as marker identifiers, normalized corner coordinates, frame dimensions and confidence are sent to the host over the authenticated encrypted local connection.

If the user cancels, the app becomes inactive, or the camera stops, new frame processing closes and pending frames and results are discarded. A calculated layout is saved only after the user reviews and applies it.

Diagnostics, Support And Website Downloads

App logs are designed not to contain display content, six-digit codes, encryption keys, or full network addresses. If a user requests support, only the device types, OS versions and reproduction details the user voluntarily provides are used to handle the request. Do not send display content, pairing codes, keys, or other sensitive information.

The official website and future package storage may use web-delivery infrastructure such as Cloudflare Pages and R2. Standard HTTPS processing may expose connection metadata—including IP address, request time, requested path, and browser or app user-agent—to that infrastructure for delivery, security, and abuse prevention. A Peaceful Journey account or email registration is not required to download the app.

Retention, Deletion And Policy Changes

SecureDisplay servers do not hold account records of display, input, or raw camera data. Local preferences and trust records may remain until the user resets them in the app or removes the app. Information voluntarily sent in a support email is retained only as needed to handle the request, investigate security issues, and meet legal obligations.

Automatic updates remain disabled until update signing and recovery are validated. If privacy practices change, the app or this page will identify the change and date. New permissions or new server transmission will not be silently enabled.
