What are cookies?

Cookies are small pieces of data that websites store on a device. Cookies can improve your visitors’ browsing experience because they help websites remember preferences and understand how people use different features. Squarespace places two kinds of cookies on visitors’ browsers:

  • Necessary cookies so visitors can navigate and use key features on your site. 

  • Non-essential, or analytics and performance cookies, that collect information on your behalf about how visitors interact with your site.

To learn more, review our Cookie Policy.

How long will cookies remain on my computer or mobile device?

The length of time that a cookie remains on your computer or mobile device depends on whether it is a “persistent” or “session” cookie. Session cookies last until you stop browsing and persistent cookies last until they expire or are deleted. Most of the cookies we use are persistent and will expire between 30 minutes and two years from the date they are downloaded to your device. See the section below on how to control cookies for more information on removing them before they expire.

How to control cookies?

You can control and manage cookies in various ways. Please keep in mind that removing or blocking cookies can negatively impact your user experience and parts of our website may no longer be fully accessible.

Most browsers automatically accept cookies, but you can choose whether or not to accept cookies through your browser controls, often found in your browser’s “Tools” or “Preferences” menu.
