Data and safety

What we know about your child, in plain English.

AdaptiveLearn is used by children, so this page is written to be read rather than to protect us. It describes what we actually do. Where something is a limitation rather than a promise, it says so.

The camera

Some chapters in the 9–11 band let a child answer by holding fingers up, tilting a hand, or holding two hands apart. It is the best part of the product and it is also the part parents ask about first, so here is exactly how it works.

The video never leaves the device, and neither do the hand positions read from it. The tracking runs inside your own browser. Each frame is looked at, turned into a few coordinates, compared with the expected answer, and discarded — all on your machine. There is no code in the app that uploads a frame or a hand position, and the app’s security policy blocks it from contacting anywhere it is not explicitly allowed to, so one could not be added quietly.

Two things we will not hide. First, the tracking software itself is a file that has to be downloaded the first time it is used, and it comes from Google’s and jsDelivr’s public file servers. Those servers see that a device asked for a file — the same thing they see when any website loads any library. They are not sent anything about your child and they never see the camera. Second, the browser asks your permission before the camera turns on, and that permission is yours to refuse.

Refusing costs your child nothing. Every chapter that accepts a hand gesture also accepts taps, with the same questions and the same scoring. A child who says no to the camera lands straight on the tap version. The camera is a nicer way to answer, never the only way.

What we store

The child’s name

Whatever you type — a first name or a nickname is fine, and plenty of our families use one. It is there so the child sees themselves in the app.

An age band

Which of the six bands they are in. Not a date of birth: we used to have a field for one, never filled it in, and removed it.

What they have played

Which chapters were opened, which questions were answered, and whether each was right. This is the whole point — it is what lets the next question be the right one.

The parent’s email

Yours, for the account. Either the address you signed up with or the one attached to your Google account.

If you asked for early access before you had an account, we also still have the email address you gave us and the age band you picked, from that request.

What we never store

  • Video, photographs or audio. None of it is recorded and none of it is uploaded.
  • Hand positions from the camera. They are read and used and thrown away, on the device.
  • A date of birth, a home address, a phone number, a school ID or a photograph of your child.
  • Anything sold, rented or shared with an advertiser. We run no advertising and have no advertisers.
  • Third-party analytics or tracking inside the product. There is no Google Analytics, no pixel, no session recorder.

Who else can see it

Nobody who is not you. A parent account can see its own children and no one else’s; a teacher can see the children in a class they created. That is not a policy we wrote down and hope everybody follows — the database itself refuses to return another family’s rows, and we test that by trying it.

Two companies hold the data on our behalf, because we do not run our own servers: Supabase stores the database and Vercel serves the app. Neither uses it for anything of their own. If you sign in with Google, Google confirms to us that the email address is yours and tells us nothing else.

Deleting it

Delete a child from your account and everything attached to them goes with it — every session, every answer, every record. Not marked as hidden: removed. If you want the whole account and everything in it gone, email support@radlor.com and we will do it and confirm when it is done.

What we have not finished

We would rather write this than let you find it out later. AdaptiveLearn is early software. Signing up is an email address and a password, or a Google account — it is not one of the formal age-verification methods that a regulator such as the American COPPA rules expect of a service aimed at young children, and we are not going to claim it is. We are working on it. In the meantime the honest position is that an adult sets the account up, and the design assumes that adult is nearby.

If a specific requirement matters to you — for a school, a district, or your own peace of mind — write and ask. You will get a straight answer about what we do and do not have, including the parts we have not built yet.

Asking us anything

support@radlor.com reaches the people who built the thing. The full legal policy is published inside the product at adaptivelearn.radlor.com/legal/privacy; this page is the same facts without the lawyering. Privacy on this website — as opposed to in the product — is its own short page.
