For grown-ups

Privacy

The short version: the games keep your child’s progress in your browser, not on our servers. No ads, no accounts, no trackers in the games.

Last updated October 24, 2026

The games

Sight Word Safari, Counting Cove, Hoot’s Discovery Lab, Dino Keys, Story Castle and Pebble Pond don’t ask for an account, an email address or a real name. They show no ads and load no analytics or advertising code.

Progress (words and numbers practised, rewards, settings, and session history for the grown-up corner) is saved in your browser’s local storage on that device. To erase it, use the reset button in the game’s grown-up corner, or clear this site’s data in your browser settings.

The progress backup

Browsers, Safari especially, can clear a site’s saved data after about a week without a visit. So the games also keep a backup copy of that progress on our server, stored with our database provider, Supabase. The backup belongs to the device, not to a person: our server gives the browser a random code in a cookie and files the copy under a scrambled form of that code. The nickname is removed before anything is stored, and the backup holds no name, email or anything else that says who your child is. If the device’s copy is cleared, the game puts the backup back the next time it opens there.

If you have a Family Pass, the backup is also linked to the pass email, so another device signed in to the same pass can bring the progress over. You can turn the backup off in any game’s grown-up corner; turning it off deletes the copy on our server straight away.

When something breaks

If a game hits an error, or the narrator’s voice can’t play, the game sends us a short note about it so we can fix it: what went wrong (for example “a recording didn’t load”), which game, the kind of device and browser (like “iPad, Safari”), and which version of the game. It never includes the nickname, progress, anything your child typed or said, or any ID that could tell one child or device from another. These notes go only to our own server, where they sit in our host’s logs, and they are not used for anything but fixing bugs.

The nickname and the narrator’s voice

Sight Word Safari lets your child pick an optional nickname so the narrator can cheer them on by name. It’s saved on the device like everything else. Most of what the narrator says is recorded ahead of time, but a nickname can’t be, so the game sends that short line (for example “You did it, Maya!”) through our server to ElevenLabs, the voice service, which turns it into speech. The same happens for a word the microphone heard that isn’t on the word list.

To keep the game fast, the spoken audio for each line is cached by our host, Vercel, under the text of that line. Nothing ties it to your child, device or location. A first name or a made-up name is plenty; please don’t use a full name.

The microphone

Saying words out loud is optional and off until a grown-up turns it on in the grown-up corner. When it’s on, the game uses your browser’s built-in speech recognition. Some browsers do this on the device; others send the spoken word to the browser maker’s speech service (Google for Chrome and Edge, Apple for Safari) to turn it into text, under their privacy policies. The grown-up corner tells you which one your browser uses.

We never record or store your child’s voice. The “Hear me” playback keeps one short clip in the browser’s memory so your child can compare themselves with the narrator; it never leaves the device and is gone with the next try.

This website’s front page

The front page (the list of games, written for grown-ups) and the schools page use Google Analytics so we can see how many people visit, how they found us, and how many school requests come in. It sets cookies and shares with Google things like the pages viewed, the referring site, browser and device type, and an approximate location worked out from your IP address. We’ve turned off Google signals and ad personalization, so this data isn’t used to build ad profiles. Google Analytics is not loaded in any game or on this page.

You can block it with your browser’s privacy settings, a content blocker, or Google’s opt-out add-on. Google explains how it uses this data at policies.google.com.

Hosting

The site is hosted by Vercel. Like any web host, Vercel’s servers see each request’s IP address and browser details to deliver the page, and keep short-lived technical logs.

If you contact us

When a teacher, school, district or homeschool group sends a request from our schools page, we keep what they send (name, role, organization, state, number of students, devices, email and message) so we can reply. It is stored with our database provider, Supabase, or in the email tools we use to answer it, and is never added to a mailing list or shared. Write to us and we’ll delete it.

Children’s privacy

These games are made for young children, so we built them not to collect personal information from them. There are no accounts for children, chat, public profiles or leaderboards. The progress backup carries no name or contact details, and the settings that change what leaves the device (the microphone, the backup) sit behind a grown-up check. We don’t sell or share anyone’s information for advertising. If you think your child’s information reached us anyway, get in touch and we’ll delete it.

Changes and questions

If anything here changes, we’ll update this page and the date at the top. Questions, or a request to delete something: hello@fundamentaldevelopment.co.
