What Stackboard doesn’t do.

The short version

Stackboard is a free new-tab extension for Chrome. It keeps your bookmarks as ordinary Chrome bookmarks on your own device. It collects no personal information, sends nothing off your device, has no analytics, runs no remote code and has no server.

What the extension touches

Bookmarks: your spaces, stacks and links are Chrome bookmarks under Other bookmarks › Stackboard. Chrome syncs them to your other devices through your Google account, the same way it syncs any bookmark. On first run, Stackboard can copy your existing bookmarks into a space; it makes those copies on your device and leaves the originals untouched.
Favicons: icons come from Chrome’s built-in _favicon/ store. The extension sends no page addresses anywhere to get them.
Open tabs: Stackboard reads the addresses of your open tabs, on your device, to mark bookmarks that are already open and to switch to them. The toolbar button reads the current tab’s title and address when you save it. If you use Stash this window, the titles and addresses of that window’s tabs are saved as bookmarks on your device. Tab information never leaves your browser.
A few local settings: the id of its bookmark folder, the space you last had open, whether the sidebar is collapsed, a count of new tabs opened and the date of the first one (used once, to decide when to ask for a rating), whether you answered that ask, and a marker for the first day after install (used to show a tip about Chrome’s “Keep it” prompt). These stay on your device.

Permissions the extension requests, and why

bookmarks: where your spaces, stacks and links are stored.
favicon: icons next to each link.
tabs: open links as tabs, show which bookmarks are already open, save the current tab from the toolbar button, and stash a window.
tabGroups: open a stack or a space as a named tab group.
storage: the local settings listed above.

The Stash shortcut (Alt+Shift+S by default) is a Chrome keyboard command; you can change it at chrome://extensions/shortcuts.

Data sharing

None. The extension contacts no server. Nothing is sold, transferred or shared with anyone. No ads, no telemetry, no crash reporting, no analytics. Links you choose to open, such as the store page from the rating prompt, open in your browser like any other link.

Children

Stackboard is not directed at children under 13 and collects no data from anyone, of any age.
