Information for schools

For the person who signs it off: your data protection officer, your online safety lead or your business manager. Each answer here was checked against how the site works on 13 November 2026. The privacy policy and the terms remain the full statements.

In short. Pupils have no accounts and give us no personal details. A pupil's progress is kept in the browser on the device, not on our servers. There are no adverts, no chat and no third-party trackers. The only personal details we hold from a school are the staff contact details the school chooses to give us.

Data protection

What we hold, and what we never receive

About pupils: nothing that identifies them

There is no pupil login and no pupil account. We never ask for a pupil's name, date of birth, photograph or contact details. If a child types a first name into a game, it is kept in the browser on that device and is not sent to us.

What stays on the device

  • Progress. Stars, levels, the explorer a child makes and any first name typed in are saved in the browser on the device the pupil plays on. Another device, another browser or cleared browser data starts fresh.
  • Shared devices. Progress belongs to the device and its browser, not to a pupil. Up to three children can each keep their own explorer on one device.
  • The school code. Once typed in, the device remembers it, with a random id the device makes for itself so that we can count devices.

What reaches our server from a pupil's device

  • The school code and the device's random id, when the code is typed in and when the device checks that the code is still open. The id identifies no child, no person and no machine.
  • Counts of use. Which pages and games were opened, started and finished, the kind of device (phone, tablet or desktop) and whether reduced motion is on. They are added up as daily totals on our own server, with no cookie and nothing that identifies a child.
  • Counts for the school. While a school code is in use on a device, the games opened and finished are also counted against the school, by hour and by game. The count names the school, never a child, a device or a person.
  • What any website receives. Basic technical information, such as browser type and general location, used to keep the site secure and working.
  • A limit on automated requests. The server counts requests against a scrambled, one-way form of the internet address they come from. Those counts are cleared within about an hour.

If a browser sends Do Not Track or Global Privacy Control, nothing is counted. Counting can also be turned off on a device with the switch on the privacy page.

What a school gives us: staff details, never pupils'

  • Asking for the free week: the school's name, your role if you give it, your email address and the start day if you choose one. We keep the request so that each school has one free week, and we count how many devices type the code in.
  • Ordering a licence: the school's name, the contact's name and email, and any purchase order number and billing details you give us, to raise the invoice.
  • Feedback after the week: what you write, your star rating, whether we may quote you and the name you give for that.
  • A message to us: your email address, your name if you give it, your message and the page it was sent from.

With a request or an order we also keep a scrambled, one-way form of the internet address it came from, to stop automated requests.

Who is responsible, and who else handles it

Eternal Raine Ltd is the data controller for the information above. The privacy policy sets out why each item is used and the lawful basis for it. School requests, orders and feedback are held on our own server. The providers who process data for us are Hostinger, who host the website; our email provider, who sends the emails you ask for; Stripe, for payments and invoices; and Google, which stores the list from the Future-Ready Check, a quiz for parents. Some providers, such as Google, are based in the United States; where data leaves the UK it is protected by safeguards recognised under UK data protection law.

We do not sell data and we do not share it with advertisers.

How long we keep it

  • A free-week request, its device count and any feedback: while we are in touch with the school and for up to two years after.
  • An order and a licence record: while the licence is open, and its invoice and payment records for as long as the law requires for tax and accounting (in the UK, six years after the end of the financial year they belong to).
  • A message from the site: deleted once it is answered and closed, or within six months, whichever is sooner.
  • The daily counts hold nothing about a person, so there is nothing in them to delete.

Your rights, and the Children's Code

To see, correct or delete what we hold about you or your school, email hello@captaincleo.com. You also have the right to complain to the Information Commissioner's Office (ico.org.uk).

We design with the Information Commissioner's Age Appropriate Design Code (the Children's Code) in mind: privacy is high by default, nothing is collected from the child, there is no profiling for advertising and no chat with strangers. This describes how we work. It is not a certificate or a claim of formal compliance.

If your school's process needs a questionnaire filled in, or an answer in writing, send it to the same address and a person will answer.

Safeguarding and online safety

What a pupil will and will not meet

No contact with anyone

  • No chat and no online play with other people. A pupil has no way to message another player, and nobody can contact a pupil through Captain Cleo.
  • Nobody from Captain Cleo meets, messages or supervises pupils. The games run in the browser.
  • One message form, for grown-ups. Ask the Captain asks for an email address and sits on the home, schools, parents, prices and help pages, never on a game page.

No adverts, and nothing to buy

  • No adverts on any page.
  • Nothing inside a game costs real money. Games pay coins that a child can spend on looks in the Store, and coins are never sold.
  • No third-party trackers, and no third-party scripts, fonts or video players. The film is served from our own site.

No live AI

Every character is scripted and says the same thing every time. Some Detective Deck cases teach how chatbots and other AI tools work; none of them connects a pupil to one.

What the games are about

The islands on scams, loot boxes, adverts, debt and crypto explain how those things work, so that a child can recognise them. No game involves real money or gambling. The money games teach how money works; they are not financial advice.

What can leave the device, and links out

  • A picture to keep. After a few big moments a game offers a picture of the moment. It is made on the device, carries no name, and is not sent to us or to anyone.
  • Links. Game pages link only to other Captain Cleo pages. Four menu pages (All games, the Captain's Chart, Cleo's Music and the Store) carry our company credit in the footer, which links to the company's own site.

If something worries you

If you or a pupil see anything in a game that concerns you, email hello@captaincleo.com and say which game. A person answers.

Accessibility

Where we are today

This is an honest account, not a claim of conformance. We have not had an independent accessibility audit, and we do not claim to meet the Web Content Accessibility Guidelines.

What works today

  • Touch. Every game can be played by touch, and with a mouse on a laptop or desktop.
  • The pages for grown-ups can be used with a keyboard: a visible focus ring on every link and button, and a menu that opens, closes with Escape and returns focus. The home page, the schools page and this page also begin with a skip link.
  • Phone to desktop. Those pages fit a phone without sideways scrolling, and the header and footer controls are at least 44 pixels high.
  • Reduced motion. When a device asks for reduced motion, page animations stop. The games are built to follow the same setting, though we have not checked every one.
  • Sound is optional. One speaker button turns it off, and the calm music stays off until someone turns it on.

What is not done yet

  • Screen readers. The games are visual and are not built for screen readers.
  • Keyboard-only play. Some games also work with a keyboard. Most are not built for it.
  • Captions. The trailer film has no captions or transcript yet.
  • Reading. The questions in the money games are written text, with no read-aloud option.
  • Zoom. Most of the reward games switch off pinch-zoom.
  • Contrast. Text is light on a dark background throughout. Our own automated contrast check still flags some lines on some pages, and we are working through them.

Tell us what gets in the way

If something does not work for a pupil or a member of staff, email hello@captaincleo.com and tell us what got in the way and on which device. It decides what we fix first.

For your IT lead

What it runs on

  • A web browser. Nothing to install, no app, no plug-in and no pupil login.
  • One address to allow. The pages, games, fonts, pictures, sound and the film are all served from captaincleo.com, over https.
  • An internet connection is needed to load the games.
  • Browser storage. Progress and the school code are kept in the browser's own storage. If your devices clear browser data when a pupil signs out or the device restarts, progress is cleared with it and the code needs typing in again.
  • The school code is typed once on each device and opens every game on it until the week or the licence ends.
  • Hosting. The site is hosted by Hostinger.
