Andrell Education and GDPR
We take your data privacy seriously and follow UK data protection law (the UK GDPR and the Data Protection Act 2018).
This page is a plain English summary. The full details are in our Privacy Notice and Legal Notice.
Your rights
Under UK data protection law you have the right to: ask for a copy of your personal data; have it corrected; have it deleted; ask us to restrict how we use it; object to how we use it; receive it in a format you can take elsewhere; and withdraw your consent at any time where we rely on consent. To use any of these rights, email support@bigmaths.com. We will reply within one month. If you are unhappy with how we have handled your data, please tell us first so we can put it right. You can also complain to the Information Commissioner’s Office (ICO) at https://ico.org.uk or on 0303 123 1113.
Legitimate interest
The law gives several lawful reasons for using (“processing”) personal information. One of them is “legitimate interest”. Broadly, this means we can use your personal information if:
- we have a genuine and legitimate reason; and
- we are not harming your rights and interests.
We carefully weigh any effect on you and your rights, and we may rely on legitimate interest for:
- preventing fraud;
- keeping our systems secure;
- keeping business records; and
- running and improving our websites and services.
We send news and marketing emails only to people who have subscribed to receive them, and we use analytics cookies only if you accept them in our cookie banner.
Some services need your information to work. If you choose not to give it, we will be unable to provide that service. We keep information only for as long as we reasonably need it, and we will delete your data if you ask us to and we are able to.
Andrell as the data controller
We are the data controller for the information we collect from you. Our Privacy Notice and Legal Notice set out how we act as data controller. We use other companies to help us provide our services. They process data on our behalf and have contracts in place with us. Our Privacy Notice lists them.
Andrell as the data processor
When a school uses Big Maths Online, the school is the data controller for its pupils’ data and we process that data for the school, under our agreement with it. We do not look at this information without the school’s permission.
How we protect your information
We build privacy into how we collect, store and process data, and we use security measures to protect your personal information against unauthorised access, alteration, disclosure or destruction.
Where your data is stored
Our Andrell Education websites are hosted by IONOS on servers in the UK. Big Maths Online and the Big Maths at Home database are hosted by Node4 on servers in the UK. Big Maths at Home web pages and images are delivered by Amazon Web Services (including Amazon CloudFront), whose servers can be outside the UK, for example in the United States. Some of our other providers, including Mailchimp and Google, are based in the United States. Where data leaves the UK, we rely on safeguards approved for UK data: the UK Extension to the EU-US Data Privacy Framework or the UK International Data Transfer Agreement or Addendum.
