Children's Privacy Policy
Last updated: October 23, 2026
This page has not had a legal review yet. It describes what the site does today. It is not legal advice, and it is not a claim of certification or compliance with any specific law or standard.
Kidorizon is made for children from Pre-K to Grade 12, so we try to collect as little as possible about them. Kids can play without an account, and guest play is never saved. Only a parent or guardian can create an account or add a child profile. This page follows the ideas behind the U.S. Children's Online Privacy Protection Act (COPPA) and describes what the site actually does today.
What we collect about a child
- As a guest: nothing about the child is saved. Each answer is sent to our server only so it can be checked, then it is thrown away. The grade picked, sound and read-aloud settings, and a short list of recently played puzzle ids (to avoid repeats) are kept in the browser on your own device. Brain Games also keep there a list of missed puzzle ids with dates (for review a few days later), a count of rounds this week with the weekly goal, and the Grade 9–12 switch for AI-style samples.
- With a parent account (optional): a parent can add up to 3 child profiles. A profile is only a nickname and a grade band. Please use a nickname, not a real name.
- Practice results: only when a parent has picked a child profile. For each answer we store the game, the puzzle id, its grade band and topic or skill, whether it was right or wrong, a random session id and the time. From Grade 3, Brain Games may also store an optional “how sure were you” tap (sure, kind of, guessing). When a child judges an AI-style sample, we store their choice (agree, disagree or partly), which ready-made “because” reason they tapped, and whether they caught it. We do not store what the child typed, only these taps and right or wrong.
- We never ask for a child's real name, email, birthday or age, photo, voice, address, location, school, or phone number.
Parental consent record
A child profile can only be added by a signed-in parent or guardian (accounts are for adults 18 or older). Before the profile is created, the parent ticks a permission statement. We store a record of that permission with the date and time, the statement's version (2026-10-23-v1) and the exact wording, so it can be checked later. If the permission is removed (by deleting the profile or the account), the child's data is deleted with it.
The wording a parent agrees to: “I am this child's parent or legal guardian. I give permission for Kidorizon to save this nickname, the grade band, and my child's practice results (which puzzle was answered, the game, and whether the answer was right) in my account, so I can see their progress. I understand I can delete this child's data, or my whole account, at any time.”
Before a public launch we plan to have a lawyer review whether this consent method is enough, and to add stronger verification if it is needed.
What children can and can't do on Kidorizon
- No ads of any kind, and no advertising or analytics trackers or third-party scripts.
- No chat, messaging or contact with other users. No chatbot talks to your child: the “pretend AI” answers are written by people or built from simple rules.
- No user-generated content: children can't post, share or publish anything, and nothing a child does is shown to other people.
- No photos, camera, microphone or uploads. Read-aloud uses your device's built-in speech, so no audio is sent to us.
- No free-text answers are stored. Games use taps, clicks and keys; only right or wrong is saved, and only for a signed-in parent's child profile.
- No links out of the site inside the games.
- No streak pressure or pay-to-continue tricks. We don't sell children's information or use it for marketing.
Who can see a child's information
Only the parent who added the child. Database rules mean a signed-in parent can read and write only their own children's rows. Our hosting (Vercel) and our database and sign-in provider (Supabase) process the data for us so the site can work. The site owner's admin page, used to run the site and answer support requests, shows each account's child nicknames, grade bands, the permission record date and summary totals (such as number of answers and percent right). It does not show individual answers.
See, correct or delete it: parent controls
- See your child's results on Progress.
- To change a nickname or grade band, remove the profile and add a new one (there is no edit button yet), or ask us to help.
- Delete a child's progress history, or remove the child profile (this also deletes the permission record and all results), from Progress.
- Delete your whole account, which permanently deletes every child profile, permission record and result right away.
- Or email us and we will do it for you. See Parents' rights for details.
How long we keep it
Child profiles, permission records and results are kept until the parent deletes them or deletes the account; we don't delete them automatically yet. Guest answers are not kept at all. Anti-abuse counters (a one-way scrambled code, never an address) are deleted after about a day. Our providers' backups may take a short while to age out after a deletion.

Changes
If we change how we handle children's information, we will update this page first. We will ask parents for new permission before collecting anything new about a child.
