Privacy notice

3JS TTD · Last updated: 8 October 2026

HappyMonkey.AI, operated by Stephen Phillips in London, UK, is responsible for this game site. Questions or privacy requests: [email protected].

Game saves and device storage

The game does not require an account. It stores the saved game (transport-tycoon-threejs:save:v2, with a legacy save key for migration), Build-panel preference (haulbridge:build-panel-collapsed), and the storage-notice dismissal preference (haulbridge:storage-notice-dismissed) in your browser's local storage on this device. The saved game is not sent to an application server. Clearing this site's browser data may remove these values.

Analytics and cookies

The game does not currently load an analytics or advertising tag, and the homepage does not set tracking cookies. Browser local storage is used for saved games, the Build-panel preference, and remembering that the cookie and storage notice was dismissed. These values remain in your browser and are not sent to the game server. If optional tracking is introduced later, this notice and the site will be updated before it is enabled.

Website delivery

When you request the site, hosting and network infrastructure necessarily processes technical connection data such as your IP address, browser details, requested resources, and timestamps to deliver and secure the website. Operational server logs are subject to the host's log-retention configuration. The site currently serves its game assets from this host.

Your rights

Where UK GDPR or EU GDPR applies, you may have rights to request access, correction, deletion, restriction, or to object to processing, and to complain to your data protection authority. Contact us at the address above to make a request.
