suprswitch — Privacy Policy

Last updated: June 28, 2026

suprswitch switches your Google account in the tab you're already on. That is
all it does. It has no servers, no accounts, no analytics, and no ads. It
collects nothing and sends nothing to us — we never see your data, because it
never leaves your browser.

WHAT SUPRSWITCH KEEPS, AND WHERE

So it can do its job, suprswitch remembers a few things in Firefox's own
extension storage. Nothing here is ever transmitted to suprswitch, its
developer, or anyone else:

— Your settings: the modifier key you choose, the number you start counting
accounts from, and the default account you set.
— Account labels: so the popup can show you people instead of /u/0, /u/1,
suprswitch reads the name, email, and profile photo already shown on the
Google page you're viewing, and remembers which account number they belong to.
— A technical hint per site: how each Google app encodes the account in its
URL, so a switch lands in the right place.

All of this lives in your browser's built-in extension storage
(browser.storage.sync). If you have Firefox Sync enabled, Firefox may sync this
data across your own devices under your account — the same way it syncs your
bookmarks. It is never sent to us.

WHAT WE NEVER DO

— We don't collect, transmit, or store your data on any server. We don't run one.
— No analytics, telemetry, tracking, fingerprinting, or ads.
— No selling or sharing of your data, ever.
— No remote code — everything the extension runs ships inside it.

THE PERMISSIONS IT ASKS FOR

suprswitch requests the minimum it needs, and only works on google.com pages:

— storage — to remember your settings and labels, in your browser.
— activeTab — to rewrite the address of the tab you're on when you press the
shortcut, so the switch happens in place.
— webNavigation — to send you to your chosen default account when you type or
bookmark a Google address.
— Access to google.com (://.google.com/*) — suprswitch runs only on Google
pages and does nothing anywhere else.

YOU'RE IN CONTROL

Everything stays on your device. To erase it, remove suprswitch from Firefox —
uninstalling clears its stored settings and labels. There is nothing for us to
delete on our end, because we never had it.

CHANGES & CONTACT

If this policy ever changes, we'll update it and the date above. Questions about
