We never collect your data.
Last updated: 20 May 2026
Marks (the "Extension") is a Chrome browser extension that replaces the default new-tab page with a personal bookmarks dashboard. This Privacy Policy describes — in plain English — what data the Extension touches, where it lives, and who can see it.
1. Summary
- The Extension does not contact any remote server.
- The Extension does not collect analytics, telemetry, crash reports, or any usage data.
- All bookmarks, workspaces, collections and tags you create are stored locally on your device in
chrome.storage.local. - No third parties receive any of your information through the Extension.
- There are no accounts, no sign-up, no login.
2. What data the Extension handles
The Extension lets you save and organize the URLs, page titles, descriptions and tags you choose. This data is created and read entirely on your device. Specifically:
- URLs and titles you save (manually or via the toolbar popup, context menu or keyboard shortcut).
- Tags, descriptions, collections and workspace names you create.
- UI preferences (selected theme, active workspace).
To bring in bookmarks you already have, export them from any browser as an HTML file and drop that file into the Extension. The file is parsed entirely on your device and the entries are written to the Extension's own local storage. The Extension does not access your browser's native bookmarks.
3. Where the data is stored
Exclusively on your device, inside the browser profile, via the standard
Chrome Extension storage API (chrome.storage.local).
Uninstalling the Extension wipes that data automatically.
4. Permissions
Chrome shows the user a list of permissions on install. Here is exactly why each one is requested:
storage— Used to persist the user's bookmarks, workspaces, collections, tags and UI preferences between browser sessions.contextMenus— Used to register the right-click "Save to Marks" item on pages and links.activeTab— Used by the toolbar popup to read the URL, title and favicon of the tab the user is currently on, so the popup can pre-fill the bookmark form. No other tab is ever accessed.
5. Third parties
None. The Extension contacts no remote endpoints, embeds no analytics or
advertising libraries, and ships no remote code. Page favicons displayed in
the dashboard are loaded from Google's public favicon service
(www.google.com/s2/favicons) using only the host name of each
saved bookmark — same behavior that Chrome itself uses to render favicons.
6. Children's privacy
The Extension is a general-purpose productivity tool. It is not directed at children under 13. We do not knowingly collect personal information from anyone — including children.
7. Changes to this policy
If we ever change how Marks handles data, this page will be updated and a new version of the Extension will be published in the Chrome Web Store with a clear changelog entry. Material changes will be flagged in the Extension on first launch.
