You can confirm this by inspecting the login window and checking the URL to ensure it's Sonos. ➤ Limited Data Storage: We only store a temporary access key to communicate with your Sonos system, with no other personal data stored. Analytics are minimal and limited strictly to operational needs. ➤ Easy Data Control: Instantly revoke access through your Sonos account or directly within the extension. Right-click on the Cast to Sonos icon, select "Options," and choose "Clear data" to remove settings and access keys. For those seeking extra privacy and performance, enable the "Disable front-end scripts" option. This feature prevents the extension from adjusting background colors to your current open tab, but reduces page load times. However, this script is highly optimized and runs only after a page has fully loaded so you will probably not see a difference. ———————— PLANS & SUBSCRIPTIONS ➤ Free Plan: Access basic casting features and enjoy standard audio quality. ➤ Premium Trial: Explore premium audio fidelity with a free trial of our enhanced sound quality. ➤ Premium Plan: Upgrade to premium for high-fidelity audio and the best streaming quality your Sonos speakers can offer. For more details and subscription options, explore the plans in the extension settings. ———————— COMPREHENSIVE SUPPORT & REGULAR UPDATES Our team is dedicated to providing a smooth experience with reliable support. Contact us anytime through the Chrome Web Store Support page, and we'll help resolve any issues. We release regular updates to address user feedback, ensure compatibility, and improve performance, so your Cast to Sonos experience keeps getting better. ———————— FAQ: Common Questions about Cast to Sonos ➤ Will this replace my Sonos app? No, Cast to Sonos works alongside your Sonos app, allowing you to control playback, volume, and device selection from either platform. ➤ Why is there a delay? While casting from your browser can introduce a delay due to network streaming, Cast to Sonos now automatically solves this with frame sync technology that measures your Sonos delay and syncs video playback to match. You can customize this behavior in the extension settings (right-click the extension icon and select "Options"). ———————— Transform your Sonos speakers into the ultimate browser-powered streaming system with Cast to Sonos – the essential tool for every Sonos user who wants total control and flexibility.
