Privacy

Rollercoaster Earth is guest-first. You can design, simulate, analyze, save locally, and open shared rides without an account.

Guest data

Guest projects and preferences are stored in your browser. Shared RCE2 links contain the project document in the URL; anyone who receives a link can open the design it contains.

Optional accounts and cloud projects

If you sign in, Supabase processes your email address, authentication identity, and optional name or avatar supplied by Google. Projects you choose to sync are stored with your account. Row-level security restricts private projects to their owner. You may continue using the local workspace without signing in.

Billing

Stripe processes Studio Pro checkout, card details, invoices, and subscription management. Rollercoaster Earth stores Stripe customer and subscription identifiers plus entitlement status, but never receives or stores full card details.

Hosting and real-site providers

Vercel hosts the application and may process ordinary request metadata needed to operate and secure the service. When real-site visual context is enabled, the browser may request licensed map tiles from the selected provider and show that provider's required attribution. Visual tiles are not used as the engineering terrain surface.

We currently do not run advertising trackers or sell personal information.

Retention and requests

Local data remains until you clear it. Account, cloud-project, or billing data is retained while needed to provide the service, meet legal obligations, and resolve payment disputes. Email brunnerconcepts@gmail.com to request access, correction, or deletion.

Children

Rollercoaster Earth is not directed to children under 13.
