In the daily operations of The Green Web Foundation, we use a number of third party services, who process data on our behalf – our data processors.

We use these services to work with clients, manage contributions to our publications, host our websites and digital publications, and handle communications like email.

Each supplier we use has a policy that explains what data they process, how they process it, how long they keep it, and how they keep it safe.

Where data is stored

The Green Web Foundation website is hosted in the UK. Our Member portal servers are hosted in Finland.

Where organisations who process data on our behalf are are based outside the European Economic Area (the EEA), or where data may be be transferred outside the EEA, we have put in place agreements to ensure that data is processed to the same standards of protection as European Law.

How long data is stored

We do not store data longer than necessary. We review our records every quarter to remove or anonymise data that should no longer be retained.

We use the following criteria to decide if data is necessary:

  • Do we still carry out the activities for the purpose it was provided?
  • Is this information still up to data and accurate?
  • Are we required by law to keep this data, like for tax or employment purposes?
  • Are there contractual obligations we need this data for, in order to be able to honor them?

How we keep data safe

We take care to choose services and tools that make it possible to follow good security practices, like strong passwords,  2 factor authentication, and secure connections using known protocols like TLS, and SSH.

We have reviewed the privacy policies  and security practices of every service and tool we use. We have written agreements that require them to protect the personal data they process.

We limit administrative access to key individuals, and only for as long as necessary.

Further details for specific services

Accessing our websites

Information collected automatically

When you use our websites we automatically collect information about your visit. This helps us understand how to improve our site and services.

We use Cabin Analytics, a privacy-first, cookie-free, carbon conscious analytics service. This data is stored in the UK, and collection does not identify you personally. You can see a full list of the data points collected, and more about their approach to privacy, and how they follow data protection laws around the world.

Information you provide for the member portal

We collect your email address, and a username when we create an account for you, so you can update info about hosting providers and datacentres. We use this to identify you, when signing in to make updates.

Submitting information via our form builder tools

We use form builder software on our main website to collect information from you in a structured form when you apply for a position, request support and so on.

This information is stored on the same server as the website, and our existing policy for retaining data (see “how long is data stored?” above).

Using the Green Web Browser Extensions and Addons

When you use one of the Green Web browser plugins, the following information is sent to the Green Web API automatically:

  • the domain of the current page you are on – this shows if the current page runs on green power or not
  • the domain of any links on the page – this shows if sites linked to run on green power

Nothing else is sent to TGWF servers, and you can’t be identified by sending this data.

What is retained, and why

Once the information about the domains is returned to be displayed in your browser, we retain the following information:

  • the domains that were checked
  • the time of the check, at the resolution of the nearest minute

We use this to track changes to how servers behind a given domain name are powered, over time as part of our mission to speed a transition to an internet running on green power.

Since there is not a moment in the day that we have less then dozens different users per minute (on average around 20.000 checks per hour are carried out as we write) there is way to connect these sites to a certain user.

Nothing else is stored about the request, and nor anything that links a user to checking a specific domain.

Transparency and open source

We also publish the source code of as much software as we can in providing our services. You can find the source code for the API server used to carry out green checks, as well as the browser extensions for Firefox and Chrome, and for Safari. You can find out more about how Github use data in their privacy policy.

Other access data

To help prevent abuse of our services , we retain access logs at the server level, for a period of 21 days. These record:

  • The time of the request
  • The request sent
  • The status
  • That type of device sent  (specifically, the user agent)

We track this to identify patterns in usage that may affect the ability for services to function – for example, if one user is making so many requests that it stops the API working for others.

After the retention period, we delete these logs.

Aggregated Statistics

We may compile statistical data about the behavior of uses of the offered services.

For instance, we  reveal how many downloads a particular version of a browser add-on received, or say which versions or websites are most popular based on checks against the web services we offer.

None of these statements are linked to personally-identifying information in any steps of the aggregation process.
