Children's privacy
How ZUNBIX handles children's information. Last reviewed 27 October 2026.
This notice describes ZUNBIX as it is built today. Before Zunbix is opened to the public, the owner of Zunbix should have it reviewed against COPPA (and the UK Age Appropriate Design Code, if the site is offered in the UK), and have a verifiable-parental-consent step in place if any of the data practices below are widened.
What a child profile holds
A Zunbix profile is made by a grown-up and holds only:
- a nickname the grown-up types in (a first name or anything else they choose);
- a buddy — which of the ten cartoon characters they picked;
- a grade, Kindergarten through Grade 5;
- learning progress: which skills have been practised, how many questions were answered and how many were right, the level each skill is at, XP, coins, stars, which rewards are unlocked, which stories have been read, game scores, daily missions and the learning streak.
That is the whole record. Zunbix asks for no email address, surname, birthday, school, address, phone number, photograph or voice recording, and children do not have accounts of their own to sign in to.
What is not in the children's area
- No advertising. No ad network, ad script or sponsored content is loaded on any Zunbix page.
- No chat and no messaging. Zunbix has none, and nothing a child types is shown to anybody else.
- No public leaderboards. Scores, levels and collections are visible to that child and their grown-up only. Zunbix has no leaderboard of any kind.
- No links out. A Zunbix page links only to other pages on this site, plus the email address at the bottom of this notice.
- No purchases. Coins are earned by answering questions. Nothing in Zunbix can be bought with money, and there is no gambling, loot box or random reward.
- No behavioural profiling. The only thing Zunbix works out about a child is which school skills they have and have not mastered, and it uses that to choose the next question.
Where the records are kept, and who can read them
In the browser on that device, and nowhere else. A profile and its progress are held in the browser (under the keys bq.v1 and bq.settings.v1) and are not sent to Zunbix or anyone else. Zunbix has no accounts and no database of children's records. Anyone using that browser can open the profiles on it, and clearing the browser's site data deletes them.
The site's hosting may add a basic visit counter and error reporting to every page. That is page-level and is not tied to a child profile.
Read-aloud and sound
Read-aloud uses the voice already built into the browser or device. The text of a question or story is handed to that voice locally; Zunbix makes no recording, never asks for the microphone, and no audio leaves the device. Sound effects and the background tune are generated in the browser, not downloaded.
Every spoken thing is also full text on screen, so the area works with the sound off.
Seeing, changing and deleting a child's records
A grown-up can see everything Zunbix holds about a child on the grown-ups page, change the nickname, buddy and grade there, and delete a profile outright from the player menu. Deleting a profile removes it and its progress from this browser.
Because the records never leave the browser, Zunbix cannot see or remove them for you; the grown-ups page and the browser's own settings are the way. For any question about this notice, email contact@zunbix.com.
