G Dev Toolbox

Privacy Policy

Last updated: June 24, 2026

G Dev Toolbox does not collect, store, or transmit any personal data. Ever.

This privacy policy describes how G Dev Toolbox ("the app") handles information on your device. The app is developed and maintained by Gabriel Castillo as an independent project.

Data Collection

G Dev Toolbox collects no data of any kind. Specifically:

No analytics or crash reporting
No advertising identifiers
No personal information
No usage statistics
No network requests are made by the app

All functionality runs entirely on your device. Nothing leaves your Mac.

Screen Recording and Screen Content

G Dev Toolbox uses macOS Screen Recording solely to power two on-screen tools: the Loupe (magnifier) and the Color Picker. When one of these tools is active, the app reads the current contents of your display using Apple's ScreenCaptureKit framework so it can magnify the area around your cursor or read the color value of the pixel under your cursor. This screen content is processed entirely on your device and only in memory. It is never saved to disk, never transmitted off your device, and never shared with the developer or any third party. Each captured frame is held only momentarily and is continuously replaced by the next frame; all captured data is discarded as soon as the tool is turned off or the app quits.

System Permissions

The app requests only one macOS permission. All processing happens locally on your device and the data is never stored or transmitted.

Screen Recording

Required by macOS for ScreenCaptureKit, which the Loupe magnifier and Color Picker use to read the pixels under your cursor. Frames are processed in memory and immediately discarded — nothing is saved to disk.

User Preferences

The app saves two preferences to your local device using macOS standard storage (NSUserDefaults): your selected zoom level for the Loupe tool and your preferred ruler unit. These values never leave your Mac.

Third Parties

G Dev Toolbox does not integrate any third-party SDKs, analytics services, advertising networks, or data brokers. The app makes no network connections, so no data is ever shared with anyone.

Children's Privacy

G Dev Toolbox does not collect any information from anyone, including children under 13.
