TraceHush helps reduce common advertising and tracking requests while you browse in Safari. Blocking is handled by Safari using rules packaged with the extension. TraceHush does not run a remote filtering service, create an account, or receive a history of the pages you visit. PROTECTION YOU CONTROL • TraceHush uses one compatibility-focused protection configuration. After a subscribed customer enables the Safari extension, it blocks listed hosts when they appear as third-party page resources to reduce the chance of website breakage. • Use the master switch to turn all TraceHush filtering on or off. • Pause protection for the current website from TraceHush's Safari toolbar panel, or manage allowed websites in the containing app's Allowed tab. • Filter sources are reviewed at least every 14 days. Approved changes are compiled, tested, and delivered through signed app updates rather than downloaded silently by the extension. PRIVATE BY DESIGN • No account or sign-in • No analytics, telemetry, advertising SDK, or behavioral profile • No remote filter downloads • No browsing-history database • Your filtering preference and allowed website hostnames stay on your device in an App Group shared only by the TraceHush app and Safari extension SUBSCRIPTION OPTIONS • Monthly: $1.99 per month, with a 7-day introductory trial for eligible first-time monthly subscribers. Unless canceled at least 24 hours before the trial ends, it automatically converts to the monthly subscription at Apple's displayed price. • Annual: $7.99 per year, with no introductory trial • Purchase, restore, and subscription-management controls are available in the containing app and use Apple's StoreKit No TraceHush account is required. Payment and subscription administration are handled by Apple. Both plans renew automatically until canceled through Apple. Introductory-offer eligibility and localized prices are determined by the App Store. TraceHush works in Safari only. It does not filter traffic in other apps, does not provide device-wide network filtering, and cannot remove every advertisement or tracker. Website designs and advertising systems change, and some pages may need a website exception. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
