This cookie policy ("Policy") explains how Arter Unipessoal Lda. ("Arter", "we", "us" or "our") uses cookies and similar technologies on the arterjewelry.com website ("Website") and any of its related products and services (collectively, "Services").

Who we are

The Website is operated by Arter Unipessoal Lda., Rua de Serralves 761, 4150-708 Porto, Portugal (VAT number PT516007521). We are responsible for the use of cookies on this Website. You can reach us at info@arterjewelry.com.

What are cookies?

Cookies are small text files that are stored on your computer or mobile device when you visit a website. They allow the website to remember your actions and preferences, either for a single visit ("session cookies") or across several visits ("persistent cookies").

Session cookies are deleted when you close your browser. Persistent cookies remain on your device for a set period or until you delete them.

Cookies set by us are called "first-party cookies". Cookies set by other companies, such as our analytics, advertising or payment partners, are called "third-party cookies". This Policy also covers similar technologies such as pixels, tags and local storage, which we refer to collectively as "cookies".

How we use cookies

Strictly necessary cookies are placed without your consent because the Website cannot work without them. All other cookies are only placed after you have given your consent through our cookie banner. You can change or withdraw your consent at any time.

What type of cookies do we use?

  • Strictly necessary cookies

These cookies are essential for the Website to function. They keep your shopping cart, enable secure checkout and payment, remember your country, currency and language, protect against fraud, and store your cookie choices. They are set by us and by Shopify, our e-commerce platform, and by our payment providers when you check out. These cookies do not require your consent. Typical duration: from the end of your session up to one year.

  • Functionality cookies

These cookies remember choices you make to give you a more personal experience, such as the pieces saved to your wishlist or your account login. Typical duration: up to one year.

  • Analytics cookies

These cookies help us understand how visitors use the Website, for example which pages are visited most and how visitors move through the site. We use this information to improve the Website and your experience. Typical duration: up to one year.

  • Marketing cookies

These cookies are set by us and by our advertising and email partners. They are used to measure the effectiveness of our campaigns, to show you relevant Arter advertising on other websites and social media, and to personalise our emails. They may record that you visited our Website, the pages you viewed and the pieces you added to your cart. Typical duration: up to two years.

Third parties we work with

Depending on the choices you make, the following third parties may place or read cookies through our Website:

  • Shopify (Shopify International Ltd., Ireland) – e-commerce platform, shopping cart, checkout and store analytics.
  • Payment providers (including Shopify Payments, Shop Pay and Klarna) – secure payment processing and fraud prevention.
  • Meta (Meta Platforms Ireland Ltd.) – Meta Pixel, used to measure and personalise our advertising on Facebook and Instagram.
  • Klaviyo (Klaviyo, Inc.) – email marketing and personalisation of our newsletters.
  • Wishlist app – saving the pieces you add to your wishlist.

Some of these providers may process data outside the European Economic Area and Switzerland, including in the United States. Where this happens, the transfer is protected by appropriate safeguards, such as the EU-U.S. Data Privacy Framework (and its Swiss extension) or the European Commission's Standard Contractual Clauses. Each provider processes data in line with its own privacy policy.

Do we use web beacons or tracking pixels?

Our emails may contain a small tracking pixel that tells us whether an email was opened and which links were clicked. We use this to understand which content our readers find most interesting and to improve our communications.

If you do not want this pixel to load, you can read our emails in plain-text view or with images disabled. You can unsubscribe from our emails at any time using the link at the bottom of every email.

Your cookie choices

When you first visit the Website, our cookie banner lets you accept all cookies, reject non-essential cookies, or choose which categories you allow. Rejecting non-essential cookies will not affect your ability to browse and shop.

You can change or withdraw your consent at any time by clicking "Cookie preferences" at the bottom of any page. Withdrawing your consent does not affect the lawfulness of any processing carried out before you withdrew it.

You can also block or delete cookies through your browser settings. Please note that blocking strictly necessary cookies may prevent parts of the Website, such as the cart and checkout, from working properly.

Your rights

Where cookies involve the processing of personal data, you have the right to access, correct, delete or restrict that data, to object to its processing, and to data portability, in accordance with the EU General Data Protection Regulation (GDPR) and the Swiss Federal Act on Data Protection (FADP). To exercise these rights, please contact us at info@arterjewelry.com.

You also have the right to lodge a complaint with a data protection supervisory authority. In Portugal this is the Comissão Nacional de Proteção de Dados (CNPD). In Switzerland this is the Federal Data Protection and Information Commissioner (FDPIC). You may also contact the authority in your own country of residence.

Changes and amendments

We may update this Policy from time to time, for example when we start using new cookies or when the law changes. When we do, we will revise the updated date at the bottom of this page. Where changes require your consent, we will ask for it again through our cookie banner.
