This mac app shows a vectorscope to a selectable region of the desktop. This single purpose app helps photo editors color correct beautiful skin tones with applications that provide white balance but no good way to visualize the target skin tone.

When launched, a circular vector scope is shown on the desktop. Drag the small rectangular box widget over a region of skin. The pixels contain within the selection are plotted on color vector scope. Adjusted white balance using your app’s colors correction tools to get the pixels to track as closely to the skin tone line as desired.

This app does not provide any tools to adjust color. It simply visualize the color with a line for skin tones to give photo editors the vector scope popular with color grading specialists in the cinema industry.

This app is a simple pay once / no ads / no in app purchases. This app does not collect any user information nor communicates with the internet.

However, this app requires special permission for the app to see your desktop in order to function.

First launch will prompt for Screen Recording. You can grant it manually: System Settings → Privacy & Security → Screen & System Audio Recording → Desktop Vectorscope. You will need to close and restart the app.

Privacy Policy — Desktop Vectorscope for Mac

Last updated: July 19, 2026

Desktop Vectorscope is a real-time color analysis tool (a chroma vectorscope) for macOS. This policy explains how the app handles your data. The short version: we do not collect, store, share, or sell any data — everything the app does happens entirely on your Mac.

Screen Recording Data — Collection, Use, Sharing, and Retention

Desktop Vectorscope uses the macOS Screen Recording permission (ScreenCaptureKit) for one purpose only: to read the pixel colors of the screen region you select, so it can display a real-time vectorscope and color readouts on your device.

Collection: The app reads pixel data only from the region you explicitly select, and only while capture is active. You can stop capture or quit the app at any time.
Use: Pixel data is used exclusively to render the live vectorscope display and the average / center-pixel color values. It is not used for analytics, advertising, or any other purpose.
Storage and retention: Captured data is processed entirely in memory and discarded as each new frame arrives. It is never saved to disk or to any other storage. Retention is effectively zero.
Sharing and disclosure: Captured data never leaves your Mac. The app contains no networking capability and no third-party code, and we do not share, sell, or disclose any captured data to anyone, including ourselves.

Other Data

The app collects no personal information, contains no accounts or sign-in, no analytics or crash-reporting SDKs, no advertising, and makes no network connections. It links only Apple system frameworks.

Third Parties

Although the developers do not collect any data, your privacy may be affected by the software platforms used to distribute this app. Desktop Vectorscope is distributed through the Apple App Store, and Apple may collect some information through your download and use of the app (for example, App Store analytics if you have opted into). You can review what Apple collects and their privacy practices at https://www.apple.com/legal/privacy/en-ww/.

Disclaimer of Warranties

Desktop Vectorscope is provided “as is” and “as available,” without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that the app will be error-free, uninterrupted, or that its measurements will meet your requirements.

The vectorscope display and color readouts are provided for informational and creative reference only. Desktop Vectorscope is not a calibrated or certified measurement instrument and should not be relied upon for broadcast compliance, legal, medical, safety-critical, or other applications where an error in color measurement could cause harm or loss.

Limitation of Liability

You use this app at your own risk. To the maximum extent permitted by applicable law, the developers shall not be liable for any direct, indirect, incidental, special, consequential, or exemplary damages — including but not limited to loss of data, loss of profits, business interruption, or costs of substitute goods — arising out of or in connection with your use of, or inability to use, the app, even if advised of the possibility of such damages.

Changes to This Policy

This policy may be revised at any time, for any reason, without prior notice. Changes take effect when posted to this page. Your continued use of the app after changes are posted constitutes acceptance of the revised policy. Please check this page periodically for updates.
