Privacy policy

Last updated: 16 September 2026

11 Plus Blocks is made for children preparing for the 11 Plus, so we have kept it simple: the app works completely without an account, and almost nothing ever leaves the device.

This policy explains the little that does.

The short version

  • You do not need an account to use the app. Every question, quiz and flashcard works without one.
  • Without an account, your child’s progress stays on their own device and in your own own cloud backup. We cannot see it.
  • With an account, we also keep a copy of their progress and the papers they have built, so their work follows them to a laptop as well as a phone. That is the only reason we hold it.
  • The iPhone, iPad and Android apps contain no analytics and do not track anyone. There are no adverts anywhere.
  • This website and the web app use Google Analytics cookies to see how they are used, but only if you accept them. More about cookies.
  • We never sell or share personal data. There is no third party we hand data to for their own use.

What we store on the device

When your child answers questions, the app records their progress: which topics they have worked through, how many blocks they have earned, their streak, and which achievements they have unlocked.

This is kept in a file inside the app on the device, and copied to your own cloud storage so it moves with your child between their own devices: your iCloud on iPhone and iPad, your Google Drive on Android. That copy is in your Apple storage, not ours. We have no access to it and no ability to read it. Deleting the app removes the local copy.

If you are signed in, we keep a copy too. That is what lets the same progress appear on a laptop, and it is described in the next section.

We also store your settings, such as whether reminders are on and your daily goal. These stay on the device.

If you choose to sign in

Signing in is optional and does two things: it lets a purchase follow you to a new device, and it lets your child’s progress follow them between a phone and a laptop.

If you sign in with Apple or Google, we receive:

  • your email address
  • your name, if the sign-in provides one
  • an account identifier created for you

We use these to recognise your account and restore anything you have bought. We do not use them for marketing, we do not add you to a mailing list, and we do not build a profile.

And while you are signed in, we hold a copy of your child’s progress. It is the same information described above: topics worked through, blocks, streak, quiz scores and which flashcards they know. Nothing they have written, because there is nothing in the app for them to write, and nothing about them as a person. It is stored against the account identifier rather than against a name.

We also hold the practice papers they have built, so a paper made on a laptop can be printed or marked on a phone. That is the questions the paper was built from, which are our own, the date it was made, and the score if it has been marked. Again nothing written by your child, and nothing about them as a person.

Both exist so a child can carry on where they left off on a different device, including the version that runs in a browser. We do not read either, analyse them, profile with them or share them. If you never sign in, none of it ever leaves the device and your own cloud backup.

If you use Sign in with Apple and choose Hide My Email, we only ever see Apple’s relay address. We never learn your real one, and that is entirely fine for how the app works.

Accounts are handled for us by Google Firebase Authentication, and the progress copy is stored in Google Cloud Firestore. Both process this data on our instructions as our service providers and for no purpose of their own. The progress copy is held in Google’s London region, so it does not leave the UK.

A note for parents. Children this age normally sign in with a parent’s Apple ID or Google account, so the details we hold are usually the parent’s rather than the child’s. That is what we would expect and prefer. We do not ask children for personal information, and there is nowhere in the app for a child to type any.

Purchases

Purchases are handled entirely by Apple. We never see your card details, billing address, or any payment information, and we could not charge you if we wanted to.

What we do keep is a record that a purchase exists: the identifier Apple gives that transaction, which product it was for, the account it belongs to, and when we last checked it with Apple. That is what lets something bought on a phone unlock on a laptop without asking you to pay twice. It is a reference to a purchase, not a payment record, and it cannot be used to take money.

What we do not do

We want to be specific, because “we may collect” language usually hides more than it says:

  • No analytics in the apps. The iPhone, iPad and Android apps contain no analytics software. We do not know which screens are opened or how long anyone uses them. The website and the web app are different, and only if you accept: see cookies.
  • No advertising. There are no adverts and no advertising software.
  • No tracking. We do not track anyone across other companies’ apps or websites, and we do not combine data with anything from a third party. The app never shows Apple’s tracking permission prompt because it has nothing to ask for.
  • No location, contacts, photos, microphone or camera. The app does not ask for access to any of them.
  • No data sales. We do not sell personal data, and we do not share it for anyone else’s own purposes.

Cookies on the website and web app

The iPhone, iPad and Android apps do not use analytics or tracking of any kind. This section is about this website and the web app, the version of 11 Plus Blocks that runs in a browser.

Essential cookies

These make the website and the web app work, so they are always on. None of them track you.

  • Your cookie choice (epb_consent) remembers whether you accepted or rejected analytics cookies, so we do not ask on every page. It lasts a year.
  • Light or dark (epb-theme) remembers the colour scheme, if you choose one. It lasts a year.
  • Signing in to the web app. If you sign in, Google Firebase keeps you signed in using your browser’s storage. Signing out removes it.
  • Progress in the web app, including the demo, is kept in your browser’s storage so it is still there next time. It stays in that browser until you clear it.

Analytics cookies, only if you accept

If you accept, we use Google Analytics to understand how the website and the web app are used, so we can tell what helps and what does not. For example: how many people visit, which pages they read, whether they tap a button to download the app or open the web app, and which parts of the web app they use, such as starting the demo, answering a practice question or building a paper.

Google Analytics sets two cookies, _ga and _ga_P2NWCL56GP, which tell one visitor from another. They expire a year after your last visit.

It receives the pages you view, the actions above, your browser and device type, the website that sent you, and your approximate location, worked out from your IP address. It does not receive your name, your email address, your account, or anything you or your child types, and Google Analytics does not store IP addresses.

We have switched off Google’s advertising features and Google signals, so none of it is used for adverts or linked to anybody’s Google account. Google processes it for us as our service provider, and may do so outside the UK, including in the United States, under the safeguards UK data protection law requires. Google Analytics deletes the detailed records after no more than 14 months; what we look at are totals, such as how many people opened the web app in a week.

If you reject analytics cookies, or never choose, none of this happens. Google Analytics is not loaded at all, and the website and the web app work exactly the same.

Changing your mind

You can change your choice here at any time. If you reject after accepting, we stop measuring straight away and remove the Google Analytics cookies from this browser.

Your choice is saved in this browser only, so you will be asked again in another browser, on another device, or after clearing your cookies.

Reminders

If you turn on reminders, notifications are scheduled by your device itself. Nothing is sent from a server, and no notification data reaches us.

Settings links to our website and to the personal sites of the people who make the app. Those are separate websites with their own privacy policies.

How long we keep things

Progress lives on your device and in your own cloud backup for as long as you keep the app. If you have an account, we keep your account details, the progress copy and the papers you have built until you delete the account.

One thing outlives the account on purpose: the record that a purchase exists. It is kept against Apple’s identifier for the transaction rather than against you, and it is what lets you sign in again later and still have what you paid for instead of buying it twice.

Our server also keeps a short diagnostic log of whether the purchase check worked, so a family who tells us something is not unlocking can be helped. Accounts and transactions appear in it only as a scrambled reference, never as anything we can read back, and the log is limited in size so it does not accumulate.

If you accepted analytics cookies on the website or the web app, Google Analytics deletes the detailed records after no more than 14 months.

Deleting your account and your data

You can delete your account from inside the app, in Settings. Deleting it removes the account details we hold, the copy of your child’s progress and the papers they have built. Everything we hold about the account goes with the account. The progress on your device and in your own backup is not affected and stays where it is.

One thing worth knowing before you do it: work done on another device that has not yet reached this one cannot be recovered afterwards. If a child has been practising on a laptop and you delete the account from a phone that has not opened since, that work goes with it.

Deleting the app removes the progress stored on that device, and you can remove the backup with Delete my backup in the app’s settings before you go, or through your own iCloud or Google Drive settings afterwards.

If you cannot get into the app, you can ask us to delete your account instead.

Your rights

If you are in the UK or the EU, you have the right to ask for a copy of the personal data we hold about you, to have it corrected, to have it deleted, and to object to how we use it. Email us at the address below and we will respond within one month.

Our legal basis for holding account details and the progress copy is the performance of our contract with you, namely providing the app, restoring what you have paid for, and keeping your child’s progress with them across their devices. You can withdraw from this at any time by deleting your account, and the app will keep working.

For analytics cookies on the website and the web app, our legal basis is your consent. You can withdraw it at any time in cookie settings, and everything keeps working.

You also have the right to complain to the Information Commissioner’s Office at ico.org.uk.

Children

The app is designed for children, and a child using it without an account gives us nothing at all. There is no profile, no messaging, no user-generated content, no advertising and no way for a child to be contacted through the app. There is nowhere for a child to type personal information, and we never ask for any.

When an account is used, the account itself belongs to a parent in almost every case, because a child this age signs in with a parent’s Apple ID or Google account. What we then hold about the child is their progress through the questions and the papers they have built, and nothing else: no name, no age, no contact details, nothing they have written. We do not use it to profile anyone and we never share it.

The web app asks before any analytics cookie is set, and asks children to let a parent or carer make that choice. Nothing Google Analytics receives identifies a child.

Parents who would like to know what is stored, or want it removed, can contact us at the address below, or delete the account from inside the app at any time.

Changes

If we change this policy we will update the date at the top, and if the change is significant we will say so in the app.
