Privacy, in plain words.
Free play needs no account
You do not need an account to try the free playground. We do not ask children for names, birthdays, photos or email addresses. Your current creation, settings and progress autosave in your browser. Clearing browser data can remove them.
Optional private cloud plans
A creation is uploaded only when you choose to save it in My Plans while signed in. We store the plan name and scene contents, including tiles, toys and roads, with its save times and the owning parent account identifier. These plans are private to your parent account. They are not public or shared with other players. You can open them on another device signed in to the same parent account.
Basic includes 3 active cloud plans and Premium includes 50, with the same limits in Chinese and English. At the limit, you can still open and update existing plans. If Premium access ends, your saved plans are not deleted; you can still open and update them, while new saves follow the Basic limit of 3.
Deleted cloud plans move to Trash and can be restored for 30 days if your account has an available slot. This recovery window is not a promise of automatic permanent erasure after 30 days. Restoring or deleting a cloud plan is separate from the current build saved in your browser.
Optional parent accounts
Parents can sign in with Google through Firebase Authentication to save private plans. Firebase manages the parent sign-in account, including its identifier and email address. The website verifies the sign-in token and uses a Firebase-based account identifier to associate private plans with the parent. Cloudflare D1 stores the parent account identifier, account creation and visit times, and saved plans. The email shown on the account page comes from the sign-in session and is not stored in the D1 parent account record. Signing in by itself does not upload your browser's current build.
Payments are currently disabled. If checkout becomes available, Stripe will process payment details; this website will keep payment references and entitlement status rather than card numbers.
No advertising trackers in the playground
The game does not include advertising, behavioral analytics or third-party tracking scripts. Cloudflare processes network requests to serve the website and stores your private cloud plans in D1. Google Firebase provides parent authentication. These services process the information needed to deliver those functions under their own privacy policies.
Purchases are not yet open
The paid expansion is being prepared. The free playground and Basic cloud plans are available with no purchase. A parent support contact will be displayed on the purchase page before real payments are enabled, including for purchase, refund or data-removal requests.
