Marker – Highlighter & Notes runs entirely inside your browser.
- It has no server. It does not create accounts and does not ask for an email address.
- It collects no analytics, telemetry, crash reports or usage statistics.
- Everything it stores (settings and the content you create with it) is kept in your browser's local extension storage on your device. You can export it as a file and delete it at any time from the extension's settings page.
- It does not sell, share or transmit your data to anyone, because it never leaves your computer.
Permissions
The extension asks Chrome for the following, and uses each only as described:
- storage — Stores settings and a signal that keeps the side panel in sync with highlights made on the page.
- sidePanel — The highlight list and library live in Chrome's side panel.
- contextMenus — Adds "Highlight selection" to the right-click menu.
- activeTab — Lets the panel read the current tab's URL to show that page's highlights.
- Access to all sites — Highlights must be restored automatically when a page loads, without a click, on any site you read. Marker reads page text only to find the passages to re-highlight; nothing is sent anywhere.
Data retention
Data exists only in your browser's local extension storage for as long as the extension is installed. Removing the extension deletes its local data. No copy exists anywhere else.
Changes
If a future version ever changes what the extension stores or where, this page and the extension's store listing will say so before that version ships.
