Privacy & cookies policy

This is the privacy and data ethics policy of the Micro:bit Educational Foundation. It defines how we deal with your information across all our products and services. Any material changes to this policy will be communicated either directly or via a banner update to the site as relevant.

Our values


We are committed to keeping your personal data safe and secure, and handling it in accordance with our legal obligations.


We aim to make data collection and removal as simple as possible to ensure privacy.


We work with a range of partners who have their own privacy policies. Relevant policies are detailed here under Third-party websites.


We are passionate about making brilliant products and services. We use data to help us understand which content, products and services are most interesting and useful for our audience. We also use data to help us identify errors and test features. We also use personal data to stay in contact with our audiences.

Audiences - teachers and children

Although we have users of all ages, the BBC micro:bit and the resources provided on this website are designed for those aged between 8-14 and the educators who teach them. We consult with children and educators on a regular basis to help the Foundation design new products, as well as policies on data collection and processing.


The Foundation is based in the UK and subject to GDPR legislation from 25 May 2018. The Foundation is registered with the Information Commissioner’s Office.

Under Article 8 of GDPR legislation (and the UK Data Protection Bill) only children aged 13 or over are able provide their own consent. This age may vary in different nations.

As a responsible global organisation, we therefore request that children under the age of 13 seek consent from whoever holds parental responsibility for the child when using the Foundation services.

Cookies and analytics

Like most websites, the Micro:bit Educational Foundation uses cookies to learn how people are using in order to improve it. As well as the Foundation uses subdomains; i.e. platforms owned and managed by partners, which provide services such as different code editors, challenges, support and technical information and are subject to the platform’s privacy policies.

We use cookies on subdomains such as and Some of our subdomains such as and have their own policies on cookies and analytics.

The Micro:bit Educational Foundation completes a risk assessment before entering into arrangements with platform partners to ensure their policies are in line with our values and practices. Where these are managed by partners we have linked their privacy policies below.

What are cookies?

Cookies are small files that our website places on your device (computer, tablet or phone). They allow us to distinguish you from other users of our website.

Cookies contain an identifier (a string of letters and numbers) that is sent by a web server to a web browser and is stored on your device by the browser. The identifier is then sent back to the server each time the browser requests a page from the server. Cookies may be either "persistent" or "session": a persistent cookie will be stored by a web browser and will remain valid until its expiry date, unless you delete it; a session cookie, on the other hand, will expire at the end of your session, which is when you close the web browser. We use both of these types of cookie on

What are cookies used for?

Cookies allow us to recognise and count the number of visitors, to see how people move around our website, how long they spend on it and how often they return. Knowing whether you’re visiting for the first time or you’ve been here before helps us work out which features or pages are more popular with you. This lets us improve the way our website works, for example by helping us to ensure that you can easily find what you are looking for. This also helps us create more things on our website that you want to see (and less of what you don’t want). Analytics also tell us which pages on our site were the first and last you visited, which helps us in the same way.

The analytics can tell us where in the world you are and what language you have displayed on your computer. This allows us to focus more on creating exciting content that is relevant to where you live and in your language. As we are committed to users of all backgrounds, we treat all locations the same, so you will see the same content regardless of where you are.

Our website does not use cookies to target advertising and, aside from Google Analytics, we do not share cookies with any other third parties. Analytics give us an overview, including how many people are using our site each month, what countries they are in and when are popular times for visiting our site, and we may share this anonymous headline data with our founding members

What are IP addresses?

IP (Internet Protocol) addresses are used to identify computers and devices when they are connected. They are numbers, a bit like telephone numbers, assigned to each device on a network (such as your computer at home or in school) that allow devices to communicate with other devices on a computer network (such as printers, other computers or the internet). Your school, work, home or mobile network may also have its own unique external IP address that allows it to communicate with other computers and websites across the internet.

How we support privacy

On our main site (excluding third party subdomains) we support privacy in the following ways:

  • We use Google Analytics cookies on Google stores anonymised IP addresses on its servers in the US.
  • Neither the Micro:bit Educational Foundation nor Google associate your IP address with any information that can identify you personally. We don’t store personal information such as your name, age or email address in cookies.
  • We do not use geo-location data from your device but, as with other websites, we may be able to determine your approximate location from your IP address. See the section below on server logs.
  • We only share data with Google for the analytics purposes outlined in this policy.
  • Our Google Analytics dashboard can only be accessed by people working for, or on behalf of, the Micro:bit Educational Foundation.
  • We may use Google Analytics cookies on our own subdomains such as our Python editor
  • For more information about Google Analytics cookies see Google’s information about safeguarding your data.
  • Google have developed the Google Analytics opt-out browser add-on for the Google Analytics JavaScript(ga.js, analytics.js, dc.js). If you want to opt out of Google Analytics, you can download and install the add-on for your web browser here.

How long are cookies kept?

Analytics cookies are kept on your device for up to two years. See Google’s information on cookie usage for more details. You are in control of your cookies - you can delete them by following the guidance below.

On your first visit to this website you will have seen a pop-up to tell you about the purposes for which cookies are being used and the means to opt-out. Please read this cookie policy carefully for more details about the way we use cookies. Although this pop-up will not usually appear on subsequent visits you can withdraw your cookie consent at any time by changing settings in your web browser. The Information Commissioner’s Office has guidance on how to do this:

Please note that if you block certain categories of cookies some functionality of our website or third party websites such as will be reduced.

Server logs

Websites like need web servers to process all the HTTP requests coming from browsers. Web servers make a note of every request or error in logs. A human or a computer can read these logs and determine:

  • Which page and feature of the website is being requested
  • The time and date of the request
  • The IP address making the request which in turn provides the country where the IP address is located
  • The HTTP request code and the response the websever gave(e.g 404 for an error)
  • The browser and build version that made the HTTP request
  • The operating system and version of the machine making the request

The Foundation web team may look at these internal server logs to fix errors(such as the server being slow or a page being broken). We may use these logs if we think the website is under attack.

We process the data from these logs using analytics software. This assumes that the data isn’t being faked. The software processes the data, essentially counting up all the types of requests. The processed data allows the Foundation to know how the website is being used(popularity of pages or browsers) and from the IP address, we can determine which country or region is making the request.

We never combine this data with any data from any other system. So we never know how you use the website with your unique data provided to the Foundation in 3rd party systems. We also do not use this data to show you content based on a location.(So a student in Edinburgh UK has the same experience as someone in San Paulo, Brazil).

We purge logs to save space and to secure the data on a regular basis.

The Python editor

The editor at is hosted and maintained by the Foundation and is subject to this policy. This includes the use of server logs and Google Analytics (as stated above).

micro:bit classroom

Student code, names and related information are communicated between the teacher and students using a Micro:bit Educational Foundation Web service running in Amazon Web Services and a third-party communication service provided by Pusher. All data is transmitted securely via HTTPS. The third-party Pusher service cannot read student names or code. We do not retain the content of the messages. Whenever possible we switch to direct connections between the teacher and students (using WebRTC).

After creating or joining a classroom, a strictly necessary cookie containing a temporary identifier for your session is stored by your browser. This identifier is removed when you sign out or end the classroom session.

BBC micro:bit playground survey

What data are we collecting and why?

As part of BBC micro:bit - the next gen we're running the playground survey, which intends to support learning about data and scientific techniques.

As part of the survey we would like to collect the data that pupils and teachers have collected to view as a large data set, potentially giving us insights into the different situations in playgrounds across the UK. For instance your playground may be bigger or smaller, have different plants, insects or animals than another schools.

Schools that are participating in the playground survey could complete the lessons without uploading their data, and so share no data if they are most comfortable with this. The data will be viewable locally, and in replacing the programme on your micro:bit all data will be deleted from the device.

Each data set is entered by the teacher taking part in the survey except the data from “Tracking our physical activity” which is shared when a student opens their movement data file on the micro:bit, uses the class code, and chooses send.

If your school wants to include their data into the survey the below data sets are collected:

  • School name (which can then be linked to the location of the school)
  • Class name
  • Class size
  • Student age group (tick box selection of age groups)
  • Date and time of submission
  • Playground temperature - average for 4 surfaces
  • Biodiversity - species of plants, species of animals
  • Area of playground
  • Where classes participate in “Tracking our physical activity” student movement data will be shared
  • Pupils can open and view their movement data file without sharing any data
  • Movement data is only shared when they enter the class code provided by their teacher and select ‘Send’
  • The movement data shared includes data collected by the accelerometer and, where they used the activity tracker hex, the activity the machine learning model estimated the pupil was doing (e.g. walking, running)
  • The pupil rating of that movement data is shared

What will we do with this data?

This data is sent to a database in AWS London and stored by the Foundation in restricted access DropBox folders. It will be viewable on a dashboard on the playground survey data upload tool.

Internally we will use this data to understand the impact of the playground survey activities and resources, for instance how many schools have engaged with the survey and how many times, how useful do pupils or teachers find the machine learning tool. This will help us understand if our approach supported pupils and teachers to engage in these topics and lessons. We will also be sharing the reports from this information with partners.

The survey data uploaded by a teacher/class can be viewed by that teacher if they log in using their class code and password.

Data will be shared with the ONS, who will analyse this data looking for commonalities or interesting differences.

Data will be stored in a database in AWS London. We will store data from our DropBox folders in January 2025, it will then be fully deleted from our back ups by the end of February 2025.

The aggregate data and reports will continue to be available.
