                    Analytics are disabled by default. If you choose to enable them, we will begin tracking the
                    following:
                    <br />
                    <ul>
                      <li>Name of active provider (e.g. Immoscout)</li>
                      <li>Name of active adapter (e.g. Console)</li>
                      <li>language</li>
                      <li>os</li>
                      <li>node version</li>
                      <li>arch</li>
                    </ul>
                    The data is sent anonymously and helps me understand which providers or adapters are being used the
                    most. In the end it helps me to improve fredy.
