Tab Cascade does not collect, store, transmit, or share any personal data.
The extension runs entirely on your device.
The list of URLs you paste is used only to open tabs in your current browser window. Progress is kept in session storage and is cleared when the browser is closed.
The extension makes no network requests of its own and requests no host permissions. No data ever leaves your browser.
No analytics, tracking, advertising, or third-party services are used.
tabs — open the URLs you provide in new tabs and detect when each page finishes loading, so they open one after another.
storage — remember the progress of the current run (session only).
alarms — a safety timer that lets a run resume if the browser suspends the extension's background process.
sidePanel — display the extension's interface in the browser side panel.
