Your design inputs stay in the browser.
Last updated: August 16, 2026. PowerFET Lab is designed so calculator inputs and results stay in the visitor's browser.
Calculator data
Electrical values entered in the calculator are processed in the visitor's browser. PowerFET Lab does not transmit, save, upload, or associate those values with an account. Refreshing or closing the page clears the working session.
Optional analytics
Analytics is disabled unless a site operator supplies a valid measurement ID during deployment. When enabled, it may record page views and named product actions such as opening Show Math, running a sweep, or exporting a report. The integration is intentionally designed not to send electrical input values, calculated results, candidate part data, or free-form engineering text.
Normal hosting records
The hosting provider may process ordinary request information such as IP address, requested page, browser information, and timestamps for delivery, reliability, abuse prevention, and security. PowerFET Lab is prepared for deployment on Cloudflare's network; Cloudflare's own privacy terms apply to that processing.
Advertising status
Advertising remains disabled until real approved AdSense publisher and slot identifiers are configured. If advertising is activated, Google and its partners may use cookies or similar identifiers. The site operator must add an appropriate consent-management or opt-out mechanism where required and review this notice before activation.
