🚨 ALERT 🚨Dangerous dog food found
Think for yourself.
Question everything.
We are looking for secret agents who would not get goosebumps, even if they were a goose. Who do not shiver, even in a freezer. Who laugh in the face of danger, and fart in the mouth of fear.

READER INFORMATION // UPDATED 12 OCTOBER 2026
Your privacy.
For agents.
You can train here without giving us your name, email address or a photo. Your answers, Hedy choices and game score stay on this page. We don’t receive them, and they disappear when you reload.
Your browser remembers that you unlocked the spy puzzle while this tab is open. This lets you move between pages without entering SECRET again. It is a temporary setting, not an agent account.
Cloudflare delivers the site. It receives connection information, such as your Internet address, to show the pages and help keep them safe. Hedy uses prewritten lines and buttons. She doesn’t receive messages or send your replies anywhere. We don’t have advertising, sign-up forms or uploads on this version.
Keep your drawings with you. Please don’t send your home address, school, passwords or other private information. Ask a trusted grown-up if you have a question about privacy.

Information and purposes
We do not receive mission answers, drawings, puzzle attempts, Hedy choices or game scores. Hedy is a scripted training activity, not a generative chatbot. The website does not request an age, name, account, location, camera or microphone access.
Our hosting and security provider, Cloudflare, processes technical connection information. This can include an IP address, browser or device information, the requested page and the time of the request. This is used to deliver the site and protect it against misuse. We rely on our legitimate interests in providing and protecting this free reader service, taking children’s privacy into account.
If a grown-up emails us, we receive their address, message and anything they choose to include. We use that information to answer the enquiry, on the basis of our legitimate interests in responding to it. Email is handled through our Google Workspace service. Please avoid sending children’s personal information.
Storage and cookies
The site stores one value, csa-puzzle-unlocked, in this tab’s session storage after you unlock the puzzle. It contains only “yes”, identifies no person and is not sent to us. It is used only to remember the unlocked state while navigating. Browser session recovery may restore it; you can clear it by clearing the site’s browser data.
We do not set advertising or analytics cookies. Cloudflare may use essential security cookies when protecting the site. Read its security cookie information.
Providers, retention and overseas processing
Cloudflare provides website delivery and security. Its global network may process technical information outside the UK. Its privacy policy explains its processing and retention; its data processing addendum describes contractual safeguards for international transfers.
We have not enabled visitor tracking or a service that stores agents’ progress. Email enquiries are kept only while needed to handle the matter and any related legal obligations, then deleted. We do not sell visitor information or use it for advertising.
Your rights
You can ask us about your personal information, request access or correction, and ask for deletion, restriction or object to processing where the applicable law gives you those rights. Email the contact above. A parent or guardian can ask on a child’s behalf where appropriate. You can also complain to the Information Commissioner’s Office.

READER INFORMATION // UPDATED 12 OCTOBER 2026
Using the training.
For agents.
The Children’s Spy Agency is a fictional spy world. These activities are for fun, curiosity and practising your thinking skills. Completing a mission does not create an account, membership or real spy appointment.
Train somewhere safe. Ask a trusted grown-up before trying anything you are unsure about. The gadget mission is a drawing activity. Please don’t build dangerous equipment, investigate strangers or trespass.
Keep drawings and mission reports with you. The Intel section shows a gadget drawing previously published on the CSA website, credited to its agent name. New submissions are closed. Remember Protocol 14. Don’t hurt people, or anything else that might have feelings.

Nothing to Sea Here.
Following several soggy mission reports, Agent Tyler was issued with a waterproof notebook. His underwater pen is useful for taking notes. It is considerably less useful for drawing a moustache on someone who is trying to stop a mission.
YOUR ASSIGNMENT. Design something that helps an agent take notes underwater. What would it need to do?
