This privacy notice is for visitors to the Office for National Statistics (ONS) website. If you are a survey respondent and would like to find out how we collect and use your personal data, please visit our data protection pages.

What data we collect

We collect information about how you use the ONS website (ons.gov.uk) to help us improve the site and make sure it is meeting the needs of its users.

Google Analytics 4

We use cookies and page tagging techniques to enable Google Analytics 4 to collect information such as:

  • the pages you visit

  • how long you engage with the pages

  • how you arrived at the site

  • how you interact with the content

  • the files you download

  • what you search for on the site

We do not store your personal information through Google Analytics 4, for example, your name, address or internet protocol (IP) address. We do not allow Google Analytics 4 to use or share data about how you use the site. We will not identify you through analytics information, and we will not combine analytics information with other datasets in a way that would identify who you are.

Google Analytics 4 replaced Universal Analytics in July 2023. Universal Analytics was running on the site between February 2016 and July 2023. This version collected truncated IP addresses to ensure the data were not personally identifiable. These data will be deleted in July 2024 and there are currently no plans to retain or archive these data.

Hotjar

Hotjar is a third-party tool that we use to gather behaviour analytics and user feedback.

We use cookies and page tagging techniques to enable Hotjar to collect information such as:

  • your responses and feedback to pop-up surveys

  • how you have interacted with our pages in the form of heatmaps and recordings

We do not store your personal information through Hotjar, for example, your name, address or IP address. We do not allow Hotjar to use or share data about how you use the site. We will not identify you through analytics information, and we will not combine analytics information with other datasets in a way that would identify who you are.

On-site feedback forms

We use feedback forms on the site to allow you to send direct feedback or queries to our customer contact centre, for example, on our feedback page. As part of these services, we collect information such as:

  • questions, queries or feedback you leave

  • your name and email address if you choose to provide it

We only use the personal data you provide to respond to your query, please see our Stakeholder privacy policy for more details.

Cloudflare access log data

Access log data are collected by Cloudflare. These are used to provide analytical reports relating to the technical performance of the website. The raw data in access logs contains:

  • hit-level data such as the page URL

  • http status codes

  • the IP address used to access the site

IP addresses are used within Cloudflare to identify bot traffic and potential security threats. Access log data are pushed from Cloudflare into Splunk for our monitoring. If we detect activity which constitutes a breach of our terms and conditions we may share log data with our service providers to assist in identifying security threats. We will not combine Cloudflare information with other datasets in a way that would directly identify who you are.

Why we need your data

We collect information through these tools to help:

  • make sure the site is meeting the needs of its users

  • make improvements to the website

  • gather feedback to improve our services

  • respond to any feedback you send us, if you have asked us to

  • monitor use of the site to identify security threats

More details about the information we collect is available in our Cookies policy. You can also change which cookies you are happy for us to use.

Our legal basis for processing your data

The legal basis for processing anonymised data for Google Analytics 4 and Hotjar is your consent.

The legal basis for processing all other personal data is that it is necessary:

  • to perform a task in the public interest

  • in the exercise of our functions as a government department

What we do with your data

The data we collect may be shared with our technology suppliers, for example, our hosting provider.

We will not:

Where your data are processed and stored

We design, build and run our systems to make sure that your data are as safe as possible at all stages, both while they are processed and when they are stored.

All personal data are stored in the European Economic Area (EEA). Data collected by Google Analytics 4 or Hotjar may be transferred outside the UK and EEA for processing.

Where data processing happens in the United States (US), suppliers need to meet the certification standards set out in the UK-US data bridge agreement. This facilitates flows of personal data to certified US companies that have opted in to the EU-US Data Privacy Framework.

How we protect your data and keep it secure

We are committed to doing all that we can to keep your data secure. We have set up systems and processes to prevent unauthorised access or disclosure of your data -- for example, we protect your data using varying levels of encryption.
