Non-Essential Cookies

Google Analytics: analytics.js (__ga, _gat), used by Google to generate web analytics and for tracking how you use the website, compiling reports on website activity for website operators and providing other services relating to website activity and internet usage. The information generated by the cookie will be forwarded to Google servers in the U.S. for statistical analysis purposes only.

Google Adwords: Using Google Adwords code we are able to see which pages helped to lead to contact form submissions. This allows us to make better use of our paid search budget.

Youtube/Vimeo: We embed videos from our official YouTube and Vimeo channel using a privacy-enhanced mode. This mode may set cookies on your computer once you click on the YouTube video player, but YouTube will not store personally – identifiable cookie information for playbacks of embedded videos using the privacy-enhanced mode.

Hotjar: We use Hotjar in order to better understand our users’ needs and to optimize this service and experience. Hotjar is a technology service that helps us better understand our users experience (e.g. how much time they spend on which pages, which links they choose to click, what users do and don’t like, etc.) and this enables us to build and maintain our service with user feedback. Hotjar uses cookies and other technologies to collect data on our users’ behavior and their devices (in particular device’s IP address (captured and stored only in anonymized form), device screen size, device type (unique device identifiers), browser information, geographic location (country only), preferred language used to display our website). Hotjar stores this information in a pseudonymized user profile. Neither Hotjar nor we will ever use this information to identify individual users or to match it with further data on an individual user. For further details, please see Hotjar’s privacy policy by clicking on this link.

We are able to use this information to show ads and make recommendations to you if we believe you may be interested in our work or supporting our work. For more information, please see Facebook’s cookies policy by clicking here.

Pixel tags

A pixel tag is an invisible tag placed on certain pages of a website, which enables cookies to be downloaded to your browser. Pixel tags register when a particular computer and/or mobile device visits a particular page, allowing a particular user to be identified across various sites, and for targeted adverts to be served to that user across the various websites he/she visits.

Controlling pixel tags: Pixel tags are not stored on your computer or mobile device. If you disable cookies, the pixel tag will only detect an anonymous website visit.

Facebook pixel code: Facebook pixel code is a tracking pixel which matches users anonymously with their Facebook ID, enabling re-marketing, analysis, and reporting of our advertising campaigns.

For details on these cookies, please view the Facebook Cookie Policy provided at: 

Hashed lists, social media and web advertising

We may share your personal data for the purpose of targeted marketing for our campaigning and fundraising activities through Facebook advertising so that they can determine whether you are a registered account holder with them. Our adverts may then appear when you access Facebook. We may also share your personal data as part of an exclusion list for our ad campaigns, which helps us target new people for ClientEarth, rather than targeting people who have already engaged with us.

When sharing information with Facebook we will upload “hashed” personal information to Facebook Ads Manager.  Facebook then matches the hashed personal data with Facebook profiles on in their database, which will create a Lookalike audience. The process of “hashing” is commonly used in digital advertising to convert directly identifiable personal data to pseudonymous personal data for the purposes of security and privacy during data transfer. The hashed data that we share with social media platforms is deleted after between 15 mins and a few hours (subject to database size) and not used for any other purpose.

We may also use social media platform advertising tools to build audiences matching particular characteristics to serve our advertising campaigns. For example, we might target people who have shown an interest in climate change or deforestation. This targeting is based on pages and/or posts people have previously engaged with on the platform. These tools allow us to inspire new people to engage with our work, and help us spread awareness about the issues facing our planet.

If you wish to prevent this use of your data then you can adjust your settings via the social media site (

The data we send could include your name, email address, telephone number and postal address.

Please note that we may share your personal data in a similar way with other social media platforms without further notification provided we assess any new online platform as having similar functioning to Facebook as well as having the required privacy standards and protocols in place to handle this data. Where the functioning of the new social media platforms or the privacy standards and protocols in place are not sufficiently similar we will notify you of any changes to our privacy policy in this respect.

Using online platforms in this way is the most efficient way for us to reach more people who are likely to take an interest in our work, meaning we use our funds most effectively.

Other Third Party Cookies

We have also included a number of features, which allow our users to share some of our content via Facebook. This does not set a cookie by itself, but if one is present it will read it. Another service we use is provided through MailChimp, which helps us to design email newsletters, share them on social networks and integrate with our other services. ClientEarth doesn’t have direct access to those cookies and the use of those third-party cookies is governed solely by the respective service provider’s Privacy statement.

Storage Time: The cookies are stored for a period of two years unless you clear their cache and the cookies themselves.
