You can use the calculator without creating an account or submitting personal information.
Calculator data
Your appliance scenario is processed in your browser. If you choose “Save this scenario,” it is stored in your browser's local storage and is not sent to a Power Runtime account. “Copy plan” puts the appliance and planning inputs into the copied link's URL fragment so another browser can restore the plan. Browsers do not send URL fragments in normal server requests, and Power Runtime removes fragments from analytics page locations before they are sent. Anyone who receives the copied link can still decode and read those inputs, so do not put sensitive information in appliance names. Session storage may be used to avoid counting the same calculator session more than once in a browser tab.
Analytics
We use Vercel Web Analytics for aggregate page visits. When a Google Analytics measurement ID is configured, Google Analytics also receives product events such as the first calculator interaction, scenario selection, saving and outbound shop clicks. Advertising signals and ad personalization signals are disabled. We do not send appliance names, wattage values or saved scenarios with these events, and we do not use calculator inputs to build a personal profile. Vercel and Google may process technical request information under their own service terms.
External links
Manufacturer and future affiliate sites receive the normal request information associated with clicking an external link and apply their own privacy policies.
