Privacy Policy — KV-TextCatcher

Last updated: 2026-04-25

KV-TextCatcher is a macOS menu-bar utility that captures a user-selected region of the screen, runs optical character recognition on it, and places the recognised text on the clipboard.

What data the app collects

None. The app does not collect, store, transmit, sell, or share any personal information or usage data. There are no accounts, no analytics, no crash reporters, no advertising identifiers, and no telemetry of any kind.

What the app reads locally

To capture a region of the screen, the app uses Apple’s ScreenCaptureKit / CGWindowListCreateImage APIs. macOS gates these behind the Screen Recording permission, which you grant explicitly the first time you capture (or via System Settings → Privacy & Security → Screen Recording).

On capture:

• The pixel data for the selected rectangle is read into memory.
• Apple’s on-device Vision framework (VNRecognizeTextRequest) performs OCR locally. Language detection is automatic on macOS 13+ with a CJK fallback for older systems.
• The resulting text is written to the system clipboard so you can paste it wherever you were working.

This information:

• never leaves your Mac;
• is held in memory only for the duration of the capture; the pixel buffer is released as soon as OCR returns;
• is not written to disk (except the clipboard entry, which macOS manages like any other copy-paste), not uploaded anywhere, not shared with any third party.

Network activity

The app makes no network connections of its own.

Children

The app is rated 4+ and contains no user-generated content, ads, or external links.

Changes

If this policy ever changes, the updated version will be published at the same URL.
