Privacy policy

Last updated 1 October 2026

Wonderwork City is a puzzle game for children aged 8-12. We built it to collect as little as possible. In short: children never give us personal information, we use no third-party trackers or ads, and the only personal data we keep is the email address a parent or adult chooses to give us.

Children

The game has no chat, no accounts for children, no ads and no purchases. It does not ask a child for a name, email, photo, voice or location. Game progress (stars, levels, play time) is saved in the browser on the device being used, and the in-game Grown-ups panel can download or delete it at any time.

Parent dashboard

So that the parent who signed up can follow along, the game also sends a progress summary for that device to the parent's account: play time per day, stars, puzzles answered and solved, skill levels, stations and districts completed, and when the game was last played. It contains no name, text, voice, photo or location. Only the parent can see it, after signing in with a one-time link sent to the sign-up email. From the parent dashboard you can set a daily play-time limit, turn sound on or off, download all of your data, or delete the account (this deletes the email, the progress summaries and the settings straight away).

Sign-up email (parents and adults only)

To unlock the free demo we ask a parent, guardian or adult (18+) for an email address and their consent to receive Wonderwork City updates and early-access news. We store the email address, the date, the wording you agreed to, and broad context (device type such as phone/tablet/desktop, country, and which website sent you). We use the email only to send Wonderwork City news. We never sell or share it, except with a service provider that sends our emails for us.

If you believe a child entered their own email, please remove it with the form below.

Cookies

We use one essential cookie, wwc_play, which only remembers that this device has signed up so you go straight to the game next time. It contains the sign-up number and a signature, never your email. If a parent signs in to the parent dashboard, a second essential cookie, wwc_parent, keeps them signed in for up to 30 days. We do not use cookies for analytics or advertising.

Anonymous usage statistics

To improve the game we count anonymous, first-party events on our own server: page views, the game starting, and milestones such as finishing the tutorial, solving a puzzle or completing a station. Each record holds the page, the kind of device, the country, the referring website and a short visitor code. The visitor code is a one-way hash of the connection and browser details mixed with a random value that changes every day and is deleted after two days, so it cannot be used to recognise anyone across days and we never store IP addresses. No third parties receive any of this. If your browser sends Global Privacy Control or Do Not Track, we do not record these statistics at all.

Where data is kept

The site runs on Cloudflare, which processes requests on our behalf. Sign-ups, progress summaries and statistics are stored in our Cloudflare database. Anonymous statistics are kept for up to 25 months; sign-up emails and progress summaries until you remove them.

Remove my email

Enter the email address you signed up with and we will delete it straight away.

Your rights

Depending on where you live (for example under COPPA in the US, or the GDPR/UK GDPR), you can ask to see, correct or delete your data. Removing your email above, or deleting the account in the parent dashboard, deletes your sign-up record and the progress summaries. Parents can clear a child's game progress from the in-game Grown-ups dashboard.
