What are cookies and tracking tools?
Cookies are small text files that visited websites send to and store on the user's device, which can then be read during subsequent visits.
Cookies can be used, for example, to keep a session active, store the contents of a shopping cart, remember certain preferences, ensure site security, perform statistical analyses, or, subject to consent where required, measure advertising campaigns and personalize marketing activities.
Similar functions can be performed by other technologies, such as pixels, tags, SDKs, local storage, and other identifiers. In this policy, unless otherwise stated, the term "cookie" also includes similar storage or tracking technologies.
What types of cookies do we use?
Strictly necessary cookies
These are necessary to enable the operation of the site and the provision of services requested by the user. They may be used, for example, to:
- manage the shopping cart and save its contents;
- allow access to the customer account;
- manage the checkout process and orders;
- store necessary settings regarding country, language, or currency;
- ensure security, authentication, and fraud prevention;
- store user privacy and consent preferences.
For these tools, prior user consent is not required when they are strictly necessary for providing the service.
Preference and functional cookies
These allow the site to remember certain choices made by the user and provide additional features or more personalized browsing. When these tools are not strictly necessary, they are used according to the user's expressed preferences.
Analytics cookies
These may be used to understand how users interact with the site, measure visits, page views, traffic sources, performance, and feature usage.
Analytics tools are managed in compliance with applicable law. When conditions that allow them to be assimilated into technical cookies are not met, they are activated only after the user's consent has been obtained.
Marketing and profiling cookies
These may be used to measure the effectiveness of advertising campaigns, attribute conversions, create audience segments, personalize advertising content, and conduct remarketing activities.
These tools, when they require consent under applicable law, are not activated before the user has expressed their choice.

Legal basis and consent
Cookies and other strictly necessary tools are used to the extent necessary to allow browsing and to provide the features and services requested by the user.
For non-essential cookies and tracking tools, where required by applicable law, processing is carried out based on the user's consent.
Upon first accessing the site, the user can use the dedicated banner to accept, refuse, or manage categories of non-essential cookies.

Any consent previously given can be modified or revoked at any time through the privacy preference management command available on the site.
You can change your cookie preferences at any time using the "Cookie Preferences" link or command available on the site.
How long do cookies stay active?
Cookies can be session cookies, which are deleted at the end of the browsing session, or persistent cookies, which remain stored on the device for a set period.
The duration varies depending on the individual cookie, its purpose, and the party providing it. For the main Shopify cookies, the durations indicated by the provider are reported above. For third-party tools, different periods may apply, as described in their respective policies.
How to manage cookies?
In addition to the preference management system available on the site, the user can configure their browser to block, limit, or delete cookies.
