Hush does not collect, store, or transmit any personal data.

• No data collection. Hush has no analytics, tracking, accounts, or servers.
• No message access. Hush only changes how the Slack page looks (hiding the sidebar, swapping the tab icon and title marker). It does not read, store, or send the content of your messages, channels, or workspace.
• Local setting only. Whether focus mode is on is saved in your browser’s local storage on app.slack.com (hush-focus-on). It never leaves your device.
• One network request. To draw the gray tab icon, Hush downloads Slack’s public logo image from https://a.slack-edge.com. No cookies or personal information are sent with this request.
• Permissions. Hush runs only on https://app.slack.com/* and requests no other browser permissions.
