The page to read before you say yes.

A teacher has asked to use one of our worlds. Here is what it does with student information, how a school can pay, what it runs on, and where it falls short on accessibility.

1. Student privacy

We collect nothing from students.

What a child types or says stays on the device unless a teacher exports it. There are no student accounts, so there is no roster to upload and nothing to sync.

The label states each limit plainly: where a name or nickname is typed, how Readaloud handles recordings, and which files a teacher can export from it.

What we collect from students

Nothing. What a child types or says stays on the device unless a teacher exports it.

Accounts or logins
NoneNo world has a sign-in, and neither does Readaloud.
Names
First name or nickname, device onlyShell Island asks each child for a first name or nickname. In Readaloud the teacher types a nickname for each reader. Both are saved on that device. A nickname leaves it only inside a file the teacher exports from Readaloud.
Voice recordings
Never uploadedReadaloud listens to a child read. It holds the recording in memory and removes it when the teacher confirms the result, or after about 3 hours. It writes a recording to the device’s storage in two cases only: once when the teacher accepts an app update, and when the teacher turns on “Keep recordings” for a reader after ticking that a parent or guardian agreed. That switch is off by default. Kept recordings leave the device only if the teacher exports them by hand.
Stored on the device
Progress, notebooks, resultsStars, class progress, notebook pages, shell banks and reading results are saved in the browser on the classroom device.
Leaves the device
Only files a teacher exportsReadaloud can export a results file, a CSV, a PDF report, its numbers-only learning log and, for readers with “Keep recordings” on, the kept recordings. Each is made only when the teacher asks for it. Its label lists what each one holds.

Each world’s page carries its own label, because the worlds are not all the same.

2. Purchase orders

How a school will pay

Grade Team: $149 a year for up to 6 teachers in one building, by card or purchase order.

Opens with checkout in December 2026. Prices are not final.

  1. Ask for a quote

    Write to us with the school’s name and the number of teachers.

  2. Receive an invoice and a W-9

    The invoice is payable to SUS AI LLC, the company behind Williams Labs.

  3. Pay it

    When the invoice is paid we set a 12-month licence for up to 6 teachers. The term can follow the school year, August to July.

  4. Renew, or do not

    A renewal quote goes out 60 days before the licence ends.

3. Devices

What it runs on

  • Runs in the browser. Built for classroom Chromebooks and iPads.
  • Nothing to install. Each world is a web page.
  • Readaloud: Chrome on a laptop, or Safari on a tablet through Add to Home Screen. Its first load downloads about 153 MB of speech files, once per device.
  • The Flooded Forest is the exception: it is made for desktop Chrome and needs hardware WebGL2.

4. Accessibility

An honest statement

This website is built to meet WCAG 2.1 AA: real text, visible focus, keyboard access throughout, and no motion for visitors who ask for less. It has not been audited by a third party.

The worlds are 3D scenes, and they will not fully conform. What they do offer: Matter Explorers, Georgia, My State and Shell Island read their words aloud. Matter Explorers needs no typing and has a projector size. Shell Island has larger projector text, reduced motion and high contrast settings.

We plan to publish an accessibility conformance report. Until it exists, we would rather tell you this than overstate it.
