Privacy and local saving
The planner does not ask for your name, email, address or phone number.
Your plan stays in your browser
Calculator inputs live in browser memory while you work. Selecting “Save on this device” stores the current plan in this browser’s local storage. It does not upload the plan to our own database or create a quote request. Anyone using the same browser profile may be able to open the saved plan.
Use “Reset example” to clear the saved planner copy from local storage. Browser settings can also clear site storage. Local saving may be unavailable in restricted browser modes.
Exports and external links
CSV export creates a file on your device. Printing uses your browser’s print dialog. Supplier links open external websites with their own privacy practices. The hosting platform may process technical access information, such as IP address, browser information and request logs, to deliver and protect the site. This is separate from the calculator's local storage. We have not added advertising, tracking pixels or an analytics integration.
No simulated submissions
This site has no lead form, payment form, mailing-list sign-up or analytics integration. We do not present a local calculation as a supplier quote or completed order.
