Universal Sign Out support

Universal Sign Out is a prerelease Safari extension for Mac, iPhone, and iPad, developed by Tylor Mayfield. This page describes the current prerelease. It is not an announcement of App Store availability.

Set up Safari access

Open the Universal Sign Out companion app and follow its setup steps.
Enable Universal Sign Out in Safari's extension settings. On iPhone and iPad, find Safari under Settings → Apps → Safari, then Extensions. On Mac, open Safari → Settings → Extensions.
In Safari's website access settings for Universal Sign Out, allow access to all websites. Confirm this setting yourself. The companion app can check whether the extension is enabled on supported systems, but it cannot confirm your all-websites permission.
Return to the companion app to confirm a subscription with Apple or choose Restore purchases for an active subscription.

If Safari warns that another app is interfering with clicks while you enable the extension, cancel the prompt and enable the checkbox yourself. Use Touch ID only when you intentionally chose Universal Sign Out. Keep Safari's security safeguard enabled. See Apple's extension guidance.

Sign out of the current site

Save unsynced work before using the extension. Clearing site data can remove local drafts, preferences, and offline data.

On Mac, click Universal Sign Out's door-and-arrow button in Safari's toolbar.
On iPhone and iPad, open Safari's page menu and choose Universal Sign Out. Some Safari versions place it under Extensions in that menu.
To use the optional floating Sign out button, turn it on in the companion app and reload an existing website tab. Closing the button hides it until that page reloads or navigates.

The extension clears supported local login data, then returns to the site's home page in the same tab. It does not open an extra tab. If cleanup cannot finish, it shows a notice on the page when possible. Protected pages or missing website access may require a Safari toolbar popover instead.

What cleanup covers

Cleanup targets the current origin's local storage, session storage, IndexedDB databases, Cache Storage, and service workers, plus cookies that apply to the current hostname. An origin includes the site's protocol, hostname, and port. Cookies shared by a parent domain can also affect related subdomains.

This is local browser cleanup. It does not revoke server sessions or sign out other devices. A site's single sign-on service may sign you back in. Use the website's own sign-out control when you need it to end a server session.

If sign-out does not finish

Close other tabs for the same site and retry. They can keep databases open or recreate cookies. Reload the site to check whether you are already signed out after a partial cleanup notice.

Confirm Safari has granted website access. Private browsing, Safari settings, and other protected pages are unsupported. If access needs refreshing, open the companion app while online. If a site signs you back in through single sign-on, use its own sign-out control.

Trial, subscription, and purchases

The current offer is a three-day free trial for eligible new subscribers, followed by an annual subscription. The US price is US$0.99 per year. Your local price and trial eligibility appear in Apple's confirmation sheet. Apple determines eligibility, and reinstalling does not create another trial.

The subscription renews automatically each year unless canceled. To avoid a trial charge, cancel through Apple at least 24 hours before the trial ends. Deleting the app does not cancel the subscription.

Use Restore purchases in the companion app with the Apple Account used for the purchase. Manage subscription opens Apple's subscription controls. Apple handles billing and refund requests.
