4. Web tracking

We use services provided by Marketo EMEA Limited (“Marketo”) to collect statistical data about the use of our website and to optimise our services accordingly, as  well as to carry out e-mail marketing activities. If you visit our website and use one of the aforementioned forms in the “Clean Air S olutions” product area to send us personal information (e.g. when requesting a call-back or signing up for the newsletter), you will be asked as part of the registration form to consent to the processing of your personal data.

Marketo also uses cookies in accordance with S ection ‎3 of this policy. The information the cookie generates about your use of our website is transferred to and  stored on a Marketo server. This server may be located in a country which does not have an equivalent level of data protection, in which case data protection is  ensured via the conclusion of standard data protection contracts or the Privacy Shield agreement. On our behalf, Marketo will use this information to evaluate the use of the website by the registered individuals and to create reports about activities on our website. You can opt out of cookie storage and change this setting at any time. You can also prevent the use of cookies in general by changing the corresponding setting in your browser software.

We would also like to inform you that, after receiving your consent, Marketo will analyse your us age patterns on our behalf when sending you the newsletter (cf. S ection ‎7 of this policy) or other requested information. To enable this analysis, the e-mails contain web beacons, also known as tracking pixels. These are one-pixel image files which link to our website and allow us to analyse your us age patterns. The data obtained in this way is used to create a user profile so that we can tailor the newsletter to your interests. We record when you read our newsletters and which links you click on and use this information to deduce your personal interests. We link this data with the actions that you carry out on our website.

Tracking is not possible if displaying pictures is deactivated by default in your e-mail application. In this case, however, the newsletter will not be displayed properly and you may not be able to use all functions. If you manually permit the pictures to be displayed, this will enable tracking as described above. You can also prevent tracking by changing your cookie use settings.
