Privacy Policy

Last updated: April 16, 2026

RedEye VB ("the App") is a Mac application that emulates the Nintendo Virtual Boy console. This Privacy Policy explains what information the App does and does not collect.

Summary

The App does not collect, store, or transmit any personal information. No analytics, no telemetry, no advertising SDKs, no crash reporters, no third-party services of any kind. The App functions entirely on your Mac.

Data the App Reads on Your Device

To do its job, the App reads the following data from your Mac. None of this data ever leaves your device.

• ROM files that you explicitly choose via the standard macOS file picker. These are read-only and remain on your local filesystem.
• Save states and SRAM (battery save) files are written next to the ROM you choose to play, in the same folder. The App never moves them off your Mac.
• App settings (such as your selected display mode, palette, and controller mapping) are stored on your local device using Apple's standard NSUserDefaults — a property list inside the App's sandbox container.
• Screenshots and video recordings that you choose to capture are written only to the folder you select in the standard macOS save panel.

Network Use

The App uses your local network for one feature only: link-cable netplay between two copies of the App on the same Wi-Fi network. This is implemented via Apple's standard Bonjour discovery (_redeye-netplay._tcp) and a direct TCP connection between peers you choose to play with.

• No data is sent to any internet server.
• No user identifiers, account names, or telemetry are exchanged.
• The peer-to-peer connection carries only the raw bytes the original Virtual Boy hardware would have sent over its physical link cable.

You may decline local network access at any time in System Settings → Privacy & Security → Local Network. The App will continue to work fully for single-player use.

Data the App Does NOT Collect

The App does not collect, request, or have access to:

• Your name, email address, or any account credentials
• Your contacts, calendars, photos, or other Mac data outside the files you explicitly open
• Your location
• Crash reports or analytics
• Any unique device identifier

Children's Privacy

The App does not knowingly collect any information from anyone, including children under the age of 13.
