What we measure

This is the whole of it. Every line below is generated from the app itself rather than written out, so it cannot say one thing and do another — and the same list is on the “What we measure” screen inside the app, from the same file.

Never: an IP address, a user agent, a cookie, a device fingerprint, an email address, a postal address, a photograph, a child's name, anything a child typed or said, the question or the answer. No advertising, no other company, ever. It is kept on our own server and sold to nobody.

The pages before you sign up

Everything above is about the app, and the app is unchanged: nothing there is shared with anybody. Outside it, /early now carries a Meta (Facebook) advertising pixel, because that is the page our adverts point at — so if you arrive from an advert, Facebook is told that somebody reached it. It is told nothing else: not whether you go on to sign up, not what you typed, not who you are. Signing up is reported to nobody. That is also the whole of where it is: not on the free quizzes, which children use; not on anything behind the sign-in; and switched off entirely for anyone who is signed in, on every page. We would rather say this plainly than have you find it in a browser tool.

While a child is using the app

Counted so we can see whether children come back, and whether they are getting better.

A child started using the app. This is how we know whether children come back in their first week and a month later.
How long that sitting lasted, in seconds.
Which subject a child opened, so we know which ones are used.
A child started a round: the subject, the kind of activity and the level. Not the questions.
Whether an answer was right, how many tries it took and how long. Never the question and never the answer.
A round was finished: how many questions, how many right, how long it took. This is how we can see a child getting better.
A child earned a reward, and which kind.

What a grown-up does

The few things done on the grown-up screens, and the weekly email.

A family's account was created.
A grown-up added a child, with their school-year band (K-1, 2-3 or 4-5) and how many children the family now has. Never the child's name.
A grown-up changed a child's list for the day, and which subjects it now holds.
We sent you the weekly progress email.
You followed a link in that email. We never record whether an email was opened.
Your answer to "which of these did they get better at?" -- one subject, or not sure. Nothing typed.
Somebody opened this page. Counted even if you switch measuring off, so we know the page is being read. always counted
You switched measuring off. It is the last thing counted about how your family uses the app. always counted
You switched measuring back on. always counted
Somebody in your household opened the members' board. Not which item, and never what anybody wrote.
You posted on the board, and whether it was a bug or a request. Never the title and never the words.
You voted for something on the board. Not which item.

The account

Your trial and subscription. These are how the account works, so they are always counted.

Your free trial began. always counted
Your trial ended, and whether you subscribed. always counted
You subscribed, monthly or yearly. always counted
A subscription ended, the reason from a fixed list, and after how many days. always counted
A subscription renewed. always counted
Your household joined through the early access page, so its ninety-day trial is read apart from the ordinary fourteen-day ones. always counted

When something breaks

So a fault can be found and fixed. Always counted, and never anything from the screen.

Something broke, what kind of thing and on which screen, so it can be fixed. No message, no details, nothing on the screen. always counted

Kept for 13 months, then reduced to monthly totals with nothing in them about any family. Ask and we delete yours; delete the household and it goes with it.

A family can switch all of this off except faults and the account, which are how the app works. It is on the “What we measure” screen: open the app, tap your own name, then “What we measure”.
