Cookies are small text files placed on your device when you visit a website. They help the website function correctly, remember your preferences, and provide information to the site owner about how the site is used.
yellow3.io uses a minimal number of cookies. We do not use cookies for advertising or tracking across other websites.
This policy covers yellow3.io and yellow3 services at buyer.yellow3.io, including the Digital Product Passport Buyer Platform and yellow3 EU Desk. We use strictly necessary storage for core functions and, if you actively consent, Google Analytics 4 to understand use of our public pages.

If you choose “Yes, allow analytics”, yellow3 loads Google Analytics 4 on public pages. Google Analytics may set identifiers such as _ga and related _ga_* cookies so we can understand aggregate site usage. Analytics is not loaded before consent, and choosing “No, only essentials” does not limit access to the site.
When you make a payment through our website, Stripe may set cookies on your device to process the transaction securely and prevent fraud. These cookies are governed by Stripe's Privacy Policy.
Your analytics choice is stored locally in your browser so we can remember it. That preference record is used only to apply the choice you made.
You can control and delete cookies through your browser settings. Most browsers allow you to:
Please note that blocking all cookies may affect the functionality of our website, particularly during the payment process.
Strictly necessary cookies and storage are used to sign you in, remember the organisation you are acting in, process payments, secure the service and remember your cookie choice. We do not ask for consent for storage that is strictly necessary to provide those functions.
Analytics is optional. Google Analytics 4 is loaded only after you actively choose to allow analytics. It is not enabled by continuing to browse, scrolling or closing a notice. Refusing is one click and does not reduce site functionality.
You can review or change that choice at any time:
