Cookie Notice
Effective as of November 22, 2025
This Cookie Notice explains how Higgsfield Inc. ("Higgsfield", "we", "us" or "our") may use cookies, web beacons, pixel tags, mobile analytics software, log files, or other technologies to collect certain information about your online activity. Those technologies provide us analytics and statistical information that allows us to provide improved and more relevant services and content. You may, however, disallow receiving cookies at any time through your web browser. It is not our intention to use cookies to retrieve information unrelated to Higgsfield's services. Some or all of the cookies below may be stored in your browser by Higgsfield or our partners.
Please refer to our Privacy Policy for more information on our privacy practices.
Managing your preferences
Before we dive into the details – if you are just looking to manage your preferences on our Service relating to cookies and similar technologies (including opting-out), you can do so at any time.
If you do not accept our cookies, you may experience some inconvenience in your use of our Service.
If you want to find out more about cookies and similar technologies on our Service and emails, please keep reading.
What types of technologies does Higgsfield use?
We may use any or all of the following "technologies" on our Service and in our emails:
Cookies:
A cookie is a very small text file that may be placed on your browser or in the storage on your device. There are two types: "session cookies" and "persistent cookies":
• Session cookies are cookies that disappear from your device or browser when you close your browser.
• Persistent cookies stay on your device even after you close your browser.
Please note that both Higgsfield and third-party service providers may set cookies on via our Service – these 'third party cookies'...
Pixel tags:
• A pixel tag is a single pixel, transparent GIF image with a unique identifier that can recognise certain types of data on your device (similar to how cookies do). They are used to operate and improve the Service and our email practices, including to help deliver cookies, count visits and understand usage and email campaign effectiveness.
• For example, we may put pixel tags on emails to understand how you interact with that email (whether you opened it, forwarded it, clicked on a link, etc.). These pixels may collect the time, location and operating system of the device you use to read the email.
Other similar technologies:
We may also use other tracking technologies, such as mobile advertising IDs and tags, HTML5 local storage / local shared objects (which store relevant data locally on your device), for similar purposes as described in this Cookie Notice.
So, when we refer to cookies and "similar technologies" in this Cookie Notice, such reference includes reference to the pixel tags discussed above, HTML5 local storage / local shared objects and other equivalent tracking technologies.
How can you manage your consent?
You can control or limit how cookies and similar technologies are used by taking the following steps:
• Pixel tags in emails can typically be blocked by default by configuring your preferences in your email client to block external images or setting it to show "plain text only" emails.
For more information
For more information about cookies, including about the cookies that have been set on your device and how to manage and delete them, visit www.allaboutcookies.org. Also, to learn more about targeting and advertising cookies and your choices more widely, you can go to the Network Advertising Initiative, the Digital Advertising Alliance's Consumer Choice, or if you are in Europe, Your Online Choices.
Finally, if you do not accept certain non-essential cookies and similar technologies, you may experience some inconvenience in your use of our Service. For example, we may not be able to recognise your device and you may need to log in every time you visit our Service.
