The extension does not collect any of your personal data.
Your extensions settings, track information from your deezer.com listening queue and playlists data are stored within your browser.
All data is used by the extension internally; we don't send this data to 3rd-party services.
The access is required to interact with the API of the deezer.com website and to inject the extensions functionality into the website.
Uninstall the extension normally and all local user data will be erased.
