We collect nothing from students.
What a child types or says stays on the device unless a teacher exports it. The labels below say exactly what that means, world by world.
This page is a draft. It describes how the worlds are built today. It is not yet our final policy.

The label
We collect nothing from students. What a child types or says stays on the device unless a teacher exports it.
No world has student accounts. None has advertising or tracking from us. Where something is saved, it is saved in the browser on the classroom device: stars, progress, notebook pages, reading results.
Three things deserve a careful read. Shell Island and Readaloud each keep a first name or nickname on the device. Readaloud listens to a child read, so its label spells out what happens to a recording. And Readaloud lets a teacher export files, so its label lists what each file holds.
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.

Readaloud
The listening happens on the device. Nothing is uploaded. Files leave only when you export them.
- Accounts or logins
- None
- Names
- Nicknames, kept on the deviceYou type a nickname of up to 16 characters for each reader. The guide asks for a short nickname, not a full name. The app cannot stop a real name being typed.
- Voice recordings
- Never uploadedSpeech recognition runs on the device, and the app has no upload. A recording is held in memory and removed when you confirm the result, or after about 3 hours. At most 12 readings are held at once. Reloading the page clears recordings you have not reviewed.
- Recordings written to storage
- In two cases onlyOne: when you accept an app update, held readings are copied to the device’s storage once and deleted at the next start. Two: when you turn on “Keep recordings to improve Readaloud” for a reader, after ticking that a parent or guardian agreed. That switch is off by default and is set reader by reader. Turning it off deletes that reader’s kept recordings.
- Stored on the device: readers
- Nickname, English-learner tickFor each reader: the nickname and whether you ticked “English learner”.
- Stored on the device: results
- Marks, heard words, scoresFor each reading, automatic or confirmed: word-by-word marks, what the recognizer heard for each word, the answer scores, accuracy, rate and level. Saved results never hold recordings or free transcripts.
- Stored on the device: learning log
- On by defaultA numbers-only record for each confirmed reading, plus the consent records for kept recordings. A filter keeps names, audio and transcripts out of it. You can switch it off and delete it.
- Stored on the device: settings and id
- Settings, a random device idYour teacher settings, and a random id for the device. The id is written into results files and the CSV.
- Export: results file
- When you chooseReaders’ nicknames, the automatic and confirmed records with word-by-word marks and what the app heard for each word, the device id and the app build. No recordings and no answer transcripts.
- Export: CSV
- When you chooseOne row per reading: nickname, passage, accuracy, band, words correct per minute, comprehension score, levels, whether you reviewed it, and the device id.
- Export: PDF report
- When you chooseNickname, levels, and for each reading the accuracy, rate, answers and error counts, the marked passage and a level trend. It can be downloaded or handed to the device’s share sheet.
- Export: kept recordings
- Only with the switch onExists only for readers whose “Keep recordings” switch is on. This file does hold recordings. It leaves the device only if you export it by hand.
- Export: learning log
- When you chooseThe numbers-only learning log can be exported as a file from “Help improve Readaloud”. It holds marks, scores and timings, and no name, recording or transcript.
- Ads or tracking from Williams Labs
- None
The first load downloads the speech files, about 153 MB, once per device from the app’s own address. After that it still asks its own address for updates. It sends nothing.
Sky Watch is still being built. It will get its label before it opens.
Teachers
From you: an email address, when you write to us or buy.
Today this site has no forms and no checkout. Joining the founding list means sending us an email, so we receive the address you send it from.
When checkout opens in December 2026, a payment company will take the card and collect the sales tax. We plan to count one number for each classroom link: how many devices used it in a month, with nothing stored about any device.
