Cookies are small files that are saved to the computer of each visitor to your site, and used as temporary holding places for information. Information that is saved in cookies is used to personalize the shopping experience, link visitors to their shopping carts, measure traffic patterns, and improve the effectiveness of promotions. To keep pace with legislation in many countries regarding the use of cookies, Adobe Commerce and Magento Open Source offer merchants a choice of methods to obtain customer consent. For a list of the default cookies in Adobe Commerce and Magento Open Source, the Cookie Reference.

NOTE
If you modify the default Google privacy settings to comply with the General Data Protection Regulation, it is not necessary to obtain user consent for the use of Google Analytics cookies.

Implied consent means that visitors to your store have a clear understanding that cookies are a necessary part of operations, and by using your site, have indirectly granted permission to use them. The key to gaining implied consent is to provide enough information for a visitor to make an informed decision. Many stores display a message at the top of all standard pages that provides a brief overview of how cookies are used, with a link to the store’s privacy policy. The privacy policy should describe the type of information that your store collects, and how it is used.

Operating your store in cookie restriction mode requires visitors to express their consent before any cookies can be saved to their computers. Unless consent is granted, many features of your store are unavailable. For example, if Google Analytics is available for your store, it can be invoked only after the visitor has granted permission to use cookies.

When cookie restriction mode is enabled, visitors to your store are notified that cookies are required for full-featured operations. Depending on your theme, the message might appear above the header, below the footer, or somewhere else on the page. The message links to your privacy policy for more information, and encourages visitors to click the Allow button to grant consent. After consent is granted, the message disappears.

Your privacy policy) should include the name of your store and contact information, and explain the purpose of each cookie that is used by your store. To learn more, see Cookie Reference.

NOTE
If you change the URL key of the privacy policy, you must also create a custom URL rewrite to redirect traffic to the new URL key. Otherwise, the link in the Cookie Restriction Mode message returns 404 Page Not Found.

Example storefront - cookie restriction notice {width="600"}

  1. On the Admin sidebar, go to Stores > Settings > Configuration.

  2. In the left navigation panel under General, choose Web.

  3. Expand the Default Cookie Settings section and do the following:

    Web configuration - default cookie settings {width="600"}

    • Enter the Cookie Lifetime in seconds.

    • If you want to make cookies available to other folders, enter the Cookie Path. To make the cookies available anywhere in the site, enter a forward slash (/). This value can contain only the cookie path, and cannot contain any other cookie parameters.

    • To make the cookies available to a subdomain, enter the subdomain name in the Cookie Domain field (subdomain.yourdomain.com). To make cookies available to all subdomains, enter the domain name preceded by a period (.yourdomain.com). This value can contain only the cookie domain, and cannot contain any other cookie parameters.

    • To prevent scripting languages, such as JavaScript, from gaining access to cookies, make sure that Use HTTP Only is set to Yes.

    • Set Cookie Restriction Mode to Yes.

      If necessary, clear the checkbox and click OK to confirm scope switching.

  4. When complete, click Save Config.

  5. When prompted to update the cache, click the Cache Management link in the system message. Then, refresh each invalid cache.

Step 2: Update your privacy policy

Update your privacy policy so that it reflects the information that your company collects and how it is used.
