Roundproxies Switcher does not collect, transmit, or share any user data. Proxy addresses and credentials you enter are stored locally in your browser (browser.storage.local) and are transmitted only to the proxy server you configured, solely to establish the proxy connection. The extension contains no analytics, telemetry, tracking, or remote code, and nothing is sent to Roundproxies or any third party. Removing the extension deletes all stored data.
