Privacy Policy

Last updated: August 13, 2026

The short version: Kidipedia has optional grown-up accounts, but children never sign in. There are no ads, third-party trackers, or chat features. A parent can save a child's first name, animal avatar, and grade band in a kid profile; learning progress stays on the device.

What we don't collect

• No child accounts. Kidipedia never asks a child for an email address, birthday, or sign-in.
• No advertising. There are no ads of any kind, and no advertising SDKs or networks.
• No tracking or analytics profiles. We do not use cookies for tracking, fingerprinting, or cross-site identifiers.
• No messaging or social features. Children cannot communicate with anyone through Kidipedia, and their learning work is not posted publicly.

Optional grown-up accounts and kid profiles

A grown-up may create an account using their email address. Signed-in parents can add kid profiles containing a first name, an animal avatar, and a broad lesson level (Grades K–2 or Grades 3–6). We do not ask for a child's birthday. These profile details are stored with the grown-up's account by our authentication provider, Clerk, so the same defaults are available on another signed-in device. See Clerk's privacy policy for details.

What stays on your device

Kidipedia remembers a few things so the experience feels continuous — quiz scores, game and lesson progress, recently read articles, the active kid profile, and small settings. This information is stored in your browser or app's local storage on your own device. Kidipedia does not upload learning history to the parent account. You can erase local information at any time by clearing the site's data in your browser settings (or clearing the app's storage on your phone or tablet).

Hosting and technical logs

Kidipedia is served by Cloudflare, our hosting provider. Like virtually all web hosting, Cloudflare's infrastructure processes standard technical information (such as IP addresses) transiently to deliver pages, balance load, and prevent abuse. We do not use this information to identify or profile visitors. See Cloudflare's privacy policy for details.

External links and the grown-ups gate

A few features (such as the source links on news stories) lead outside Kidipedia. These links are always placed behind a "grown-ups only" check — a simple multiplication question — so children don't leave the app accidentally. External sites have their own privacy practices that we don't control.

Children's privacy (COPPA)

Kidipedia is designed for children. Child-facing pages do not ask children to create accounts or submit contact details. Optional accounts and kid profiles are created and managed in the grown-ups area.

Changes to this policy

If Kidipedia's privacy practices ever change — for example, if we add an optional subscription for grown-ups — we will update this page and the "last updated" date above before those changes take effect. The commitment that will not change: no ads, and no selling or sharing of personal information.
