Frequently Asked Questions
- Which plan is right for me?
- Laminar covers occasional sizing checks. Transitional suits engineers running calculations regularly during a design cycle. Turbulent adds the ThermoSketch AI assistant and the highest compute quota for teams iterating daily.
- How do I cancel my subscription?
- Manage your subscription anytime from your account billing page. After cancelling, you keep access to your current plan until the end of the billing period you already paid for.
- Which payment methods are supported?
- Payments are processed by Dodo Payments (our Merchant of Record), supporting major credit and debit cards.
- Is my simulation data stored?
- No. Your simulation inputs and results are not uploaded to a database — a simulation runs, returns its results to your browser, and nothing is retained server-side. Saving a project downloads a local .json file to your own device; loading one reads it back from your device.
