Do I need internet to use the calculators?

Only once, to load the app for the first time. After that, everything works fully offline — perfect for the field, warehouses or remote sites.

Can I use it on more than one device?

Yes. If you clear your browser data or switch devices, just enter the same license key again — it's tied to your purchase, not to one device.

Is this a subscription?

No. Every calculator is a one-time purchase — pay once, use it for as long as you like.

Can the dashboards be customised to my organisation?

Yes — dashboards are delivered with your own data, branding and structure. Get in touch for a quote tailored to your operation.

What payment methods are accepted?

Calculators are sold via Gumroad, which accepts international cards. For dashboards, payment can be arranged directly, including local options.
