Our data promise

This page is for you, not for a grown-up. It says what we know about you, who can see it, and how to make it go away. There is a longer version for grown-ups on the privacy page, and it says all the same things.

What we know

Not much, and none of it is secret from you.

• A name to call you. Your grown-up picked it when they set this up. It can be anything. Lots of people use a nickname.
• What school year you are in. That is how we pick the right maths.
• The Starling you made and the hats and paint you have won.
• Your answers. Every question you have done, whether you got it right, and when you did it.
• How long you were away from a SATs mock test. If you leave one part way, its clock keeps going. Your grown-up can see how long you were away, and whether the time ran out.

What we never ask for

We do not have a box for any of these, so nobody can put them in:

• Your real name
• Your birthday
• Your school
• Where you live
• A photo of you
• Your phone number, or an email address of your own

You do not have your own way of logging in either. You practise inside your grown-up's, which is why you never had to make a password.

Why we keep your answers

Two reasons, and that is all.

So the questions fit you. If you keep getting something right, we make it harder. If something is tricky, we come back to it. That only works if we remember what happened last time.

So your grown-up can see how you are getting on. They can see which topics you have been doing and what you have won. That is the point of them setting it up.

Who can see it

Your grown-up, because it is their account. And us, because we built it and we sometimes have to fix things.

Nobody else. Not other children. Not their grown-ups. Not your school. We do not sell it to anyone, and there are no adverts here, so there is nobody to sell it to.

Sometimes, when your grown-up asks us to email them a code to sign in, a company called Cloudflare checks that a real person is asking, not a computer program. It looks at the tablet or computer, not at you. It never sees your name, your answers or your Starling, and it is not there when you practise.

You can make it go away

Ask your grown-up. In the app they go to For adults, then Children, and they can remove you. When they do, all of it goes: your answers, your Starling, your trophies, everything. It is not hidden. It is gone.

We keep a spare copy of everything in case something breaks. Each spare copy is thrown away after 14 days, so after 14 days it is gone from those too.

You are allowed to ask for this. It is your maths and it is your Starling.

Counting, but not watching you

We count things like how many people got started this week. That is adding up numbers, and it never says anything about you on your own. We are not watching what you do.

On this website, a company called Vercel counts for us each time a page is opened. It writes down when, which page, the page you came from, which town or city, and what kind of tablet or computer it was. It never knows your name. Vercel says that after a day it stops keeping track of which visits go together.

You can switch this counting off. It only switches off in the browser you are using now, like Safari or Chrome, on this tablet or computer. It can switch itself back on: if this website's saved things are cleared from the browser, or if you do not use this website for about a week in Safari.

If something is wrong

If a question looks wrong, there is a button under the answer that says Something wrong with this question? Press it. It tells us about the question and the answer you gave, and nothing about who you are.

If the app or this website breaks, it tells us too, so we can fix it. It tells us what broke, which page it was on, what kind of tablet or computer it was, and when. It never tells us who you are or anything you typed.

If you are worried about anything on this page, tell your grown-up, and they can email us at hello@brightwren.co.uk. A real person reads it.

This is about the BrightWren Maths app, where your grown-up signs in. If you are just doing the practice on this website without signing in, we keep nothing that says who you are: the questions happen on your own computer. Vercel counts the pages you open, as it says above, unless you switch that off. If a page breaks, it sends us a note about the page, and nothing about you.
