Privacy notice

This early-validation site uses a random identifier stored in your browser to count unique visits and completed calculations. We record only the identifier, page path, interface language, event type, and time. Engineering inputs and calculated values are not uploaded.

Feedback and product interest

If you submit feedback, we store its category, message, interface language, and your optional email address. If you join a product-interest list, we store your email, selected use case, interface language, and submission time so we can evaluate demand and send the related launch notice. Joining does not create a purchase or subscription.

Do not include confidential drawings, customer information, internal calculations, or other sensitive data.

Purpose and retention

Data is used only to evaluate whether this tool is useful and to prioritize improvements. It is not sold or used for advertising. Raw validation data may be retained for up to 12 months, then deleted or converted into aggregate counts.

Your choices

You may use the calculator without submitting feedback or joining an interest list. Clearing this site's browser data resets the local anonymous identifier. To request access or deletion, choose “Privacy or data request” in the feedback form.
