KiddoKeys is a Chrome extension that turns your keyboard into a fullscreen, toddler-safe playground. This is the full privacy policy. We are committed to keeping it as short and as honest as humanly possible.
KiddoKeys does not collect, store, transmit, share, or sell any personal information about you, your child, or your device.
That's not marketing — it's the architecture of the extension. KiddoKeys declares zero permissions in its manifest, makes zero network requests, contains zero analytics scripts, and opens zero connections to any server.
When you click the extension icon and press "Start playing", the extension opens a single in-browser page (fun.html) bundled inside the extension. That page:
Listens for keyboard, mouse and touch events on its own page.
Draws colorful letters, numbers, emoji and animations in response.
Plays cheerful sounds generated in real time with the Web Audio API (no audio files are downloaded).
Saves your theme, sound on/off, and confetti on/off preferences in your browser's local storage so they persist between sessions.
That is the entire scope of the extension.
Personally identifiable information (name, email, address, phone): No
Authentication credentials: No
Health information: No
Financial or payment information: No
Personal communications: No
Location (precise or approximate): No
Web browsing history: No
User activity, clicks, keystrokes, mouse movements: No — events are processed in-page and discarded immediately
Content of websites you visit: No
IP address, device ID, advertising ID: No
KiddoKeys does not request any Chrome permissions, including tabs, storage, cookies, webRequest, host_permissions, or any other permission that could read or modify your browsing.
The extension uses your browser's localStorage API to remember three preferences:
Selected theme (rainbow, space, ocean, or candy)
Sound on/off
Confetti on/off
This data lives only on your device, in your own browser profile, and is never transmitted anywhere. You can clear it any time via your browser's "Clear site data" tools or by uninstalling the extension.
KiddoKeys is designed for children under 13 (in fact, under 6). Because the extension does not collect any personal information whatsoever, there is no information that could be subject to the U.S. Children's Online Privacy Protection Act (COPPA), the EU GDPR's special protections for children's data, or any equivalent regulation.
Parents may use the extension with their children with the same level of data confidence as using a calculator app or a paper notebook.
KiddoKeys does not load any third-party scripts, fonts, analytics, ads, trackers, or content delivery networks.
The parent-menu Ko-fi support buttons open https://ko-fi.com/kiddokeys in a new browser tab when (and only when) you tap them. At that moment you are leaving KiddoKeys and Ko-fi's privacy policy applies — see https://more.ko-fi.com/privacy. KiddoKeys does not pass any information to Ko-fi beyond the act of opening the URL.
The extension's manifest.json declares:
"permissions": []
That empty array is the heart of this privacy policy. KiddoKeys is incapable of accessing your tabs, your browsing history, your cookies, your bookmarks, your downloads, your microphone, your camera, your location, or any other site you visit.
If we ever change the extension in a way that could affect privacy, we will:
Update this document with a new "Last updated" date.
Bump the version number in the Chrome Web Store listing.
Note the change in the listing's "What's new" section.
We will never quietly add tracking to a previously private extension.
Questions, concerns, or compliance requests:
Ko-fi: https://ko-fi.com/kiddokeys
Website: https://kiddokeys.app (forthcoming — until then, please use Ko-fi messaging)
Chrome Web Store: use the "Support" tab on the listing page.
This policy is released into the public domain. Adapt it freely for your own zero-data-collection project; we'd love it if more extensions could truthfully say what we just said.
