FAQ

Questions about the templates

What do I get when I buy a template?

The website files for that template — HTML, CSS and JavaScript (or the WordPress version for the WordPress bundle) — delivered as an instant download after purchase on our store.

Where do I complete the purchase?

Clicking “Buy now” takes you to the product page on our store, idplr.org, where you'll see the current price, licence terms and checkout.

Can I see a template before buying?

Yes. Every template has a live demo website linked on its card, so you can test the calculators and layout first.

Do I need coding skills?

Basic HTML knowledge helps for rebranding the static templates. The WordPress bundle can be managed from the WordPress dashboard. Developers can customise everything.

Can I use the templates for client or commercial projects?

The bundles support commercial use. The exact licence (for example number of sites or resale rights) is shown on each product page — please check it before buying.

Can I show ads like Google AdSense on my site?

Yes, the layouts are designed to be ad-friendly. AdSense approval depends on Google's policies and your own content, so it isn't guaranteed by any template.

What hosting do I need?

The HTML templates are static files and run on any web hosting, including shared hosting and static hosts. The WordPress bundle needs a standard WordPress installation.

I have a question before buying. Who do I contact?

Email care@calculations.one with the template name and your question.

Want to see it in action first?

Calculations.one itself is built on the HTML bundle — explore the calculators, then grab the template.
