Privacy Policy

Last updated: 2 September 2026

Glyfo does not collect, transmit, or sell any of your data. It has no network code at all — no accounts, no servers, no analytics, no advertising, and no third-party SDKs. Everything the app does happens on your PC.

What Glyfo processes

To do its job, Glyfo reads:

Glyfo only captures the screen at the moment you ask it to. It does not watch, record, or monitor your screen in the background.

Where that data goes

Nowhere. Text recognition uses the OCR engine built into Windows. On Copilot+ PCs, the improved recogniser and the translation feature use the AI models that ship with Windows and run on the device’s own hardware. Read-aloud uses the speech voices installed in Windows. None of these send your images or text off the device, and Glyfo makes no internet connections of its own.

What Glyfo stores on your PC

What Where Why
Your preferences (language, OCR options, shortcut, toggles) Windows app settings for Glyfo, on this PC only So the app remembers how you set it up. These are local settings and are not synced to your Microsoft account.
Temporary copies of images opened from other apps %TEMP%\Glyfo\ So an image shared or opened from another app survives long enough to be recognised.
A diagnostic log of app events and errors %TEMP%\Glyfo.log To make faults reportable. It records events such as “the app started” or “a file was opened”, plus error messages. It does not contain your images or the text Glyfo recognised.

You can delete the two %TEMP% items at any time; Glyfo recreates them as needed. Uninstalling Glyfo removes its settings.

Children

Glyfo is a general-purpose utility. It is not directed at children and collects nothing from anyone.

Changes

If this policy changes, the updated version will be published at this address with a new date at the top.
