Section 01 • Data Protection
Privacy Policy (100% Local & Offline)
Last updated: November 8, 2026
MirrorDesk is designed from the ground up to operate completely offline. We don't collect, store, track, or share your data. Everything stays strictly on your own devices.
1. Local Peer-to-Peer Architecture
MirrorDesk acts as an AirPlay receiver on your Mac. All video frames, audio packets, and screen mirroring streams are transmitted directly and exclusively between your Apple devices (iPhone, iPad) and your Mac across your local Wi-Fi network or a direct physical USB cable. No media or network packets ever leave your local environment.
2. Information We Do NOT Collect
No Personal Information: We do not ask for, collect, or store your name, email address, phone number, or account credentials.
No Device Identifiers: We do not log UDIDs, MAC addresses, hardware serial numbers, or advertising identifiers.
No Telemetry or Analytics: MirrorDesk contains zero third-party tracking frameworks, crash analytics SDKs, advertising libraries, or cookies.
No Screen or Audio Recording Without Consent: Screen mirroring is processed in temporary system RAM. Recordings and snapshots are initiated strictly by you.
3. Local File Storage
When you choose to record your screen (.mp4) or take a screenshot (.png) using MirrorDesk, all generated media files are written strictly and exclusively to the local destination folder chosen by you on your Mac (by default, your Movies folder for recordings and your Pictures folder for screenshots). MirrorDesk has no server upload functionality.
4. System Permissions
Screen Recording Permission: Asked for only when you record your Mac's screen or Mac audio. Mirroring, snapshots and Device Only recordings don't need it.
Microphone Permission: Optional; requested only if you choose to record your voice simultaneously with your screen.
Local Network Permission: Required by macOS to discover and connect to AirPlay streams over Wi-Fi.

Section 03 • Engine Source Code
Open Source Notices & GPLv3 Compliance
The underlying AirPlay receiver core used by MirrorDesk is based on UxPlay, licensed under the GNU General Public License v3.0 (GPLv3). It runs as its own helper program inside the app (MirrorDesk.app/Contents/Helpers/MirrorDeskEngine) and passes the received video to MirrorDesk, which displays and records it.
In strict accordance with Section 6 of the GPLv3 license, all custom source code modifications, patches, and build scripts created for the streaming engine are openly and publicly available to everyone at:
The engine uses open-source libraries such as GStreamer and GLib (GNU LGPL 2.1) and several BSD and Apache-licensed components. Their licence texts ship inside the app, in MirrorDesk.app/Contents/Resources/Licenses.
Note: MirrorDesk's proprietary macOS SwiftUI application wrapper, recording pipeline, user interface, audio routing, and icons remain proprietary intellectual property, with all rights reserved.
