Ladderglass: Full Page Screenshot — Privacy Policy
Ladderglass is a browser add-on that takes screenshots of web pages and lets you mark, crop and save them. It works locally. The extension stores data only in your browser (storage.local and the add-on’s own IndexedDB); nothing is sent to Zydeno or anyone else. There are no analytics, no telemetry, no accounts, no advertising and no remote code.
Your screenshots
- Ladderglass reads a page only after you start a capture on it: with the toolbar button, a keyboard shortcut or (if you turned it on) the right-click menu. It never reads pages in the background.
- During a capture it scrolls the page (or the scroll area you chose), takes one picture of the screen per step and puts the page back as it was. The pictures are kept in the add-on’s own browser storage (IndexedDB) only while the editor tab that shows them is open. Closing that tab deletes them; captures left over after a browser crash are deleted at the next start after 12 hours.
- The marks you add in the editor (arrows, text, pixelated areas…) are saved next to the capture, so reloading the editor tab does not lose them. They are deleted together with the capture.
- Files are saved only when you press Save (or Ctrl+S); they go to your browser’s normal download folder. Copy puts a PNG picture on your clipboard only when you press Copy (or Ctrl+C) in the editor.
- Pixelate and blur replace the pixels under the mask in the saved file; the original pixels are not stored in it.
What is stored, only in your browser
- Settings: default format, JPG quality, PDF page size, the file-name pattern, theme, language, the right-click menu switch and the two capture options (fixed headers once, wait for pictures).
- A counter for the {n} part of file names, and whether the welcome tour was shown.
- Export in Settings writes these settings (never screenshots) to a file in your download folder, only when you press it.
- Which editor tab shows which capture, in the browser’s session memory (storage.session), cleared when the browser closes.
Permissions
- activeTab: gives Ladderglass access to the tab you are looking at, and only after you click its button, press its shortcut or choose its menu item. It is used to take the screenshot of that tab.
- scripting: on that same tab and only at that moment, runs Ladderglass’s own capture script, which scrolls the page, shows the progress bar or the selection frame, and puts everything back afterwards.
- storage: keeps the settings listed above and the open capture in your browser.
- clipboardWrite: lets the Copy button put the screenshot on your clipboard.
- contextMenus: adds “Ladderglass → Whole page / Visible area / Select a region / Scroll area” to the page’s right-click menu. The menu stays off until you switch it on in Settings. Opera asks for this permission at that moment and you can say no; Firefox grants it without a prompt, because the permission gives no access to pages or data.
- Ladderglass does not ask for access to all websites, your browsing history, bookmarks, downloads list or cookies.
Deleting data
- Closing an editor tab deletes its capture. Removing the extension removes all of its stored data, including settings.
This policy covers the extension only. Websites you capture have their own policies; respect the rights of others in what you capture and share.
