Cookies that help with our communications and marketing

We want to spread the word about what3words and to encourage visitors to return to our website/apps.

User behaviour on our website may also be used to build audiences for our Twitter, TikTok, Facebook and LinkedIn advertising campaigns (e.g. if you visit our website, you might be shown an advert for what3words on another website that shows adverts run by those third parties). We also use Google AdWords for “remarketing” purposes, which means showing adverts on other websites to people who have already visited our website or who have the what3words app installed in order to encourage users to return. In order to do this, we make use of cookies, which in this case are a randomly generated number that uniquely identifies a web browser on a specific computer as having visited the website or completed certain actions on the website.
