In this article, we'll describe what first and third-party cookies mean.
What are first-party and third-party cookies?
Note: Google plans to disable third-party cookies for 1% of users in 2024 for testing, with a goal phaseout third-party cookies in H1 2025. Read more here.
Dreamdata only uses first-party cookies. That means that if you're using Dreamdata's tracking script this will still work after Google has disabled third party cookies in Chrome.

First-party cookie
These are set by the publisher’s web server (or any JavaScript loaded on the website).
First-party cookies:
- Available to the domain that created it
- Supported by all browsers
- Can be blocked or deleted by the user
- Used for login, tracking, target experiences and more
Third-party cookie
Third-party cookies, on the other hand, are set via code loaded on the publisher’s website or by a third-party server - eg. AdTech vendor
Third-party cookies:
- Accessible on any website that loads third-party server’s code
- Supported by all browsers, many block the creation of third-party cookies by default.
- Users are also able to delete third-party cookies on their own.
