Privacy

Using the desktop App

The App operates locally and offline. It does not upload your design parameters, simulation results or project files.

Visiting this website

This website has no design-file upload feature. We have not added advertising trackers, analytics scripts or newsletter forms. The hosting service may process connection information such as IP addresses and request logs to deliver and protect the website.

Checkout

The payment form sends billing and payment information directly to Paddle. See Paddle’s privacy notice for its handling of that information.

Purchase delivery

We use a secure, essential browser cookie to connect your checkout to the confirmation page. It lasts up to seven days and is not used for advertising. A private download link is available after payment verification, and a copy is sent to your checkout email address. Both share the same expiry and download allowance.

Order records

We retain the minimum transaction identifiers and order status needed to verify purchases, prevent duplicate fulfillment and provide support. Payment card details are not sent to or stored by this website.

Support

If you contact us, the details you choose to send will be used to respond to your request. Avoid sending confidential circuit files unless they are specifically needed and you agree to share them.
