Superbar — Privacy Policy

Last updated: 26 August 2026

Superbar collects nothing, transmits nothing, and sells nothing. Everything it does happens on your device.

There are no servers, no analytics, no accounts, no third-party services, and no network requests of any kind.

What Superbar accesses

To group your tabs by website, the extension reads, from tabs you already have open in your own browser:

the URL of each tab — this is what determines which site a tab belongs to
the title of each tab, as part of the same tab data Chrome returns
tab group state — which groups exist, their names, colours, and whether they are collapsed
the favicon Chrome has already cached for a site, used to pick that group's colour

Superbar does not read page content. It installs no scripts into any web page, and requests no access to the sites you visit.

It does not use Chrome's browsing-history API. Chrome labels the tabs permission as “Read your browsing history”, but what that permission actually grants here is the ability to see the URLs of tabs that are open right now.

What Superbar stores

Two things, both in Chrome's extension storage on your own device:

Stored	Purpose	Lifetime
A map of tab-group id to the site that group represents	So a group can keep collecting tabs from its site, and so groups the extension did not create are never touched	Until the group is closed
Which tab was used most recently in each group	So reopening a group returns you to the tab you were last on	Held in memory only; cleared when the browser restarts

The first stores site identifiers such as github.com or docs.google.com/document. It stores no full URLs, no page content, and no history of pages you have visited or closed.

Neither is ever uploaded, backed up, or shared. Both are deleted when you uninstall the extension.

Permissions, and why each is needed

Permission	Why
`tabs`	To read the URL of open tabs. Without it Chrome removes `url` and `title` from tab data entirely, and grouping by site becomes impossible.
`tabGroups`	To create, name, colour, collapse and dissolve tab groups. This is the extension's core function.
`storage`	To keep the two local records described above.
`favicon`	To read Chrome's locally cached favicon for a site and derive that group's colour. Reads from Chrome's own cache; makes no network request.

Superbar requests no host permissions, so it has no access to the content of any website.

Children

Superbar is not directed at children and collects no data from anyone.

Changes

Any change to this policy will be published at this same address, with the date above updated.
