Universal Sign Out privacy policy
Effective November 10, 2026.
Universal Sign Out is a prerelease Safari extension and companion app for Mac, iPhone, and iPad, developed by Tylor Mayfield. This policy covers the app and extension. Visits to this website follow the separate TylorNZ privacy and cookie policy.
Website data stays on your device
When you request sign-out, the extension processes website addresses, cookies, and browser storage on your device to identify and clear the current site's supported login data. It needs Safari website access to perform that action. Cookies shared by a parent domain may also affect related subdomains.
Cleanup includes the current origin's local storage, session storage, IndexedDB, Cache Storage, and service workers, plus cookies that apply to the current hostname. Clearing data can remove local drafts, preferences, or offline content. It does not end server sessions or sign out other devices.
The app and extension do not send browsing URLs, page content, cookie values, or browsing history to Tylor Mayfield, Apple, or RevenueCat as part of cleanup. The app has no advertising, browsing analytics, or account signup. Websites you visit still follow their own privacy practices.
Settings stored on your device
The app saves the floating-button preference, setup progress, temporary action reservations, and cached subscription access on your device. The extension can also temporarily save a sign-out issue notice so it can display it when the page reloads. These records do not form a website history.
Removing local app data removes the settings and access cache held there. It does not cancel a subscription or remove purchase records held by Apple or RevenueCat. An active subscription can be restored.
Purchases and subscription access
Apple processes payments and determines trial eligibility. RevenueCat helps the app check subscription access, restore purchases, and report sales. The app uses an anonymous RevenueCat customer identifier rather than asking you to create an account.
Apple and RevenueCat process purchase information such as customer, product, and transaction identifiers, purchase status, and related technical, device, and network information. This information supports billing, purchase verification, and subscription management. Their handling and retention follow their policies and applicable requirements. Read RevenueCat's privacy policy and Apple's privacy policy.
Use Restore purchases and Manage subscription in the companion app, or follow Apple's subscription controls. Deleting the app does not cancel a subscription.
Support and privacy requests
If you email support, Tylor Mayfield receives your email address, message, and any attachments you choose to send, and uses them to respond to your request. Do not send passwords, cookie values, security codes, or private page content. Redact screenshots before sending them.
For support, privacy questions, or requests about information you have sent, contact hello@barkontrack.com. For payment records held by Apple, use Apple's privacy controls. Requests about RevenueCat's processing can also be directed through its privacy policy.
Material changes to this policy will appear here with an updated effective date. Universal Sign Out support explains setup, cleanup limits, and purchases.
