Who we are

We are Stella McCartney LTD with registered offices at 3 Olaf Street, London W11 4BE, United Kingdom, and Stella McCartney Italia SRL, with registered offices at Via Morimondo 2/3, 20143 Milano (Italia) and, for the purposes described in this Notice, we are the Main Joint Data Controllers of your Personal Data.

Stella McCartney LTD and Stella McCartney Italia SRL are collectively identified below as (“Stella McCartney” “SMC,” “we” or “us”).

When we collect your Personal Data during your purchasing process on our E-commerce (i.e. when you buy our Services online, or you are interested in a particular product and you place it in your shopping cart), we are Joint Data Controllers of your Online Shopping Data together with Drop Srl, which is the Merchant of Records for the online purchases processing activities on our E-commerce.

What data we collect and process

What data we collect and process

We may collect data from Our Pages, Mobile Applications, E-commerce, when you visit one of Our Shops, and/or when you attend one of Our Events. Data collected and the relative purposes of processing depend on how you interact with us and how you manage the settings of your Browser and the Device you are using.

You may find further details on the reasons why we process your Personal Data in the “Why we use your Data” section below.

Data you provide

You can provide us with Personal Data such as your name, phone/mobile number(s), date of birth, sex, e-mail address, postal address, payment and billing information, as well as your preferences (e.g., hobbies, job, interests, size or particular colours of your purchase history). It is the case, for example, when you use our Services, make purchases in Our Shops, participate in one of Our Events or when you ask us questions, make requests, interact with our support services or participate in our surveys. You can also choose to provide us with Information about your location if, for example, you want to search for one of Our Shops in a particular location (e.g., London, Milan, Paris, etc.) or when you order our products.

If you provide us with the data of third parties (e.g., postal addresses or payment data of third parties for a gift), you will be held responsible for having shared such information with us. You must be legally authorized to share it (i.e., authorized by the third party to share their information or for any other legitimate reason). You must fully indemnify us against any complaints, claims or demands for compensation of damages which may arise from the processing of third-party Personal Data in violation of applicable data protection law.

Data collected by the Browser and the Device

When you use Our Pages, we collect information on the Browser and the Device you are using. This information includes your IP Address, the date, time and the requested URL, Unique Identifiers and other information such as the type of your Browser or Device. Information related to your Browser or Device may include your operating system, language, network settings, telephone operator or internet provider, installed third-party applications and plug-in lists.

Some of this information is collected using Cookies, SDK and Other Tracking Technologies that are on your Browser or Device. This helps us, for instance, to avoid malfunctions during the provision of the Services, and allows us to provide you with Content that may be useful to you. You can find the complete list of Cookies and SDK we use here.

Data inferred by your activity

We collect information based on your online and offline interactions with our Services in order to improve them and to identify Content that may be useful to you. This happens, for example, when you are interested in a particular product and you place it in your shopping cart, when you click on an advertising link on Our Pages, or when you participate in Our Events. In such cases, we will attempt to provide you with relevant content.

In other cases, such as when you contact us by email, mail, telephone or otherwise regarding our products or request other information, we will collect and maintain a record of your contact details, communications and our responses. If you contact us by telephone, more information will be provided during the call.

Information about your location

We collect information about your location to allow you to view Our Shops near you, and to provide you with Content that may be useful to you. Your location can be determined by manually entering an address, city or zip code or by checking your IP Address.

Your location is determined - more or less accurately - depending on whether it is collected from the Browser or Device and on the privacy settings you have set on them. We make every possible effort to ensure that Information on your location is not used to infer your Sensitive Data.

You can limit our collection of your position by changing your Browser or Device settings, as set out in the “How to control your Data and manage your choices” section below.

Third parties we collect data from

Data collected by third parties

We may ask third-party business partners (e.g., social media, co-branding companies, etc.) to send or display our advertisements to their users on the basis of certain criteria/interests. These so-called micro-targeting and/or retargeting activities typically do not lead to the direct collection of Personal Data by SMC. Instead, they usually allow us to obtain Aggregated Information on the effectiveness of those advertisements or lead to the registration of new users or new followers. In accordance with European legislation, in carrying out these activities both SMC and our business partners make every possible effort to verify the conformity of the data (including joint controllership agreements) before they are used. You can request more information on our list of active commercial partners and the obligations of the respective parties by writing to privacy@stellamccartney.com.

When you buy our Services in one of our Shops, your Shopping Data are processed by our Affiliates operating our Shops, acting as independent Data Controllers for the related purchases processing activities.

In order to have a better insight and understanding of your needs, we may ask the Affiliates operating our Shops to send us your Shopping Data to enable us to analyse them and send you offers targeted to your interests. The transfer of your Shopping Data from our Shops to SMC is subject to your explicit prior consent.

Data collected from public or publicly accessible sources

We may collect or enrich your Personal Data with information obtained from third parties and public sources accessible within the limits of the law applicable to us. These sources may include data brokers, public registers, online newspapers, lists or public directories. Please note that a preliminary check is always carried out on the possibility to use this information, according to the best practices established by the competent Supervisory Authorities to which we are subject (the UK ICO and the Italian Garante).

For your convenience, we will collectively refer to all Personal Data mentioned here above as "Data".
