Privacy Policy

This page explains what Millioncrest: City Builder uses to run your city, save your progress, and let you play with others.

Accounts and online play

Millioncrest requires an account and internet connection. When you register, the game links its account ID to the identifier it receives from your chosen sign-in provider. The provider handles your sign-in credentials under its own privacy policy. The game saves your city and progress, profile, optional country selection, friend code, friends, and requests on its servers so you can return to the same city and play with others.

If Google or Facebook shares a display name when you sign in, Millioncrest may save it to help authorized staff identify your account. Other players see the name you choose in the game.

What other players can see

Other signed-in players may see your player name, city name, level, and company value in rankings. Choosing a country makes your city eligible for that country’s rankings. Players can view the layout of a city they visit. Sharing your friend code lets another player look up your city and send a friend request.

Device storage and sign-in

The app or browser keeps settings such as audio and notification preferences on your device. A short-lived cookie helps complete sign-in with your provider. The game uses session storage to keep you signed in.

Web purchases

Stripe handles payment details when you make a web purchase. Millioncrest stores the Stripe references, purchase status, amount, and subscription period needed to deliver purchases and manage subscriptions.

City reminders

You can turn reminders on or off in Game Settings. With permission, the app schedules reminders on your device for events such as rent becoming available or construction finishing. Browser reminders use your browser’s notification permission.

Your choices and questions

Use Settings to change your name, portrait, or country, or to sign out. You can remove friends from the Friends screen. Visit Support for help with account access, saved cities, and privacy settings.

Deleting your account

Request deletion from Delete account or from Account settings in the game. We schedule deletion of your account and associated game data seven days after you confirm. You can cancel before the scheduled time.
