Daguerre is a Chrome extension for capturing, annotating and exporting screenshots. It is built to work entirely on your device.

What Daguerre handles

When you take a screenshot, Daguerre handles:

the image of the page you captured, and any annotations you add
the page title and address (URL) of the captured tab, used to name and search your screenshots
your settings (capture delay, export quality)

If you use Copy Text or Searchable PDF, the text in the screenshot is read on your device by the built-in text recognition engine.

Where it is stored

Everything stays in your browser's local storage on your device (IndexedDB, localStorage and chrome.storage). Daguerre:

does not send screenshots, text, page addresses or any other data to any server, including ours
does not use analytics, tracking, advertising or third-party services
does not sell, share or transfer your data to anyone
does not sync your screenshots between devices

The text recognition engine and its English language model ship inside the extension and run offline.

Permissions

Daguerre asks for access to a page only when you capture it. Access to all sites is optional and requested only when you choose All tabs. You can revoke it at any time in chrome://extensions.

Desktop app

The Daguerre desktop app for macOS, Windows and Linux follows the same rules. It captures only when you ask: a selected area, a window or a screen. It stores screenshots, window titles and settings in the app's local storage on your device and sends nothing over the network. Delete screenshots from its History at any time. On macOS it needs Screen Recording access, which you can revoke in System Settings.

Deleting your data

Delete individual screenshots, or use Clear all on the History page. Uninstalling the extension removes all of its stored data.

Changes

If this policy changes, the new version will be posted here with a new date.
