Frequently Asked Questions

What is the D3pth engine®?

D3pth engine® is a browser-side JavaScript engine for creating spatial, 3D-like website layouts from regular HTML elements without requiring WebGL or canvas. It uses CSS transforms, configuration, and finite state machines to control depth, movement, and transitions.

Who develops the D3pth engine®?

D3pth engine® is a commercial software product developed and licensed by D3pth lab s.r.o. under the direction of Čeněk Svoboda, CEO of the company.

I build websites for clients. Can I buy a licence?

Yes. You may buy a WebApp and its corresponding Licence for your own project or for a client. During checkout, you specify the Licence holder and one licence target for each purchased WebApp.

One purchased WebApp may be licensed for one domain name or host name, including that name itself and all of its subdomains at any depth, or for one exact IP address. Parent domains, sibling host names, and otherwise different domains are not included. For example, a Licence for example.com includes example.com, www.example.com, and shop.eu.example.com; a Licence for shop.example.com includes shop.example.com and test.shop.example.com, but not example.com or blog.example.com. Localhost and 127.0.0.1 are permitted only for development and testing connected with the Licensed Site; they do not consume the paid licence target.

The Licence holder may be the Buyer, the Buyer's company, a client, or another person or legal entity. The Buyer confirms the applicable EULA during checkout. If the Buyer is also the Licence holder, that confirmation constitutes acceptance. If they are different and the EULA has not already been accepted by or on behalf of the Licence holder, the Licence holder accepts it by the first intentional Use of the issued Licensed Materials, as provided in the EULA.

Does D3pth lab need access to my server or website infrastructure?

No. A standard Licence does not require us to access your server, database, CMS, hosting account, source repository, or customer data. If you separately purchase a service that requires access or files for deployment, the required cooperation is handled as part of that service.

Can we reverse engineer or deobfuscate the code?

The D3pth engine® and License Notice must remain complete, readable, and unchanged as supplied. The D3pth engine® may not be modified, transformed, deobfuscated, decompiled, disassembled, or reverse engineered, and the License Notice may not be removed, obscured, detached, or altered. These restrictions do not limit rights that cannot validly be restricted under mandatory applicable law. The applicable EULA and Order define the permitted deployment and use.

Is D3pth engine® responsive?

D3pth engine® does not automatically guarantee a responsive result. Responsiveness depends on the website layout, WebApp Materials, external CSS or JavaScript, configuration, states, and transitions. The final implementation must be tested for the intended viewport sizes and devices.

What happens after I place an order?

Checkout records the Buyer details, Licence holder details, Licence holder email address, and one licence target for each purchased WebApp: one domain name or host name, including that name itself and all of its subdomains at any depth, or one exact IP address. No parent domain, sibling host name, or otherwise different domain is included.

The Buyer confirms the applicable EULA during checkout. If the Buyer is also the Licence holder, that confirmation constitutes acceptance. If the Licence holder is different, the Buyer's confirmation does not by itself constitute acceptance by that Licence holder. Unless the EULA has already been accepted by or on behalf of the Licence holder, acceptance occurs by the first intentional Use of the issued Licensed Materials.

After payment, we prepare the Licence and Licensed Materials. Once issued, they are sent to the Licence holder email address. We contact the Buyer or Licence holder only if the Order information is incomplete, unclear, or cannot be used to issue the Licence. If we cannot issue the Licence, the Order is refunded.

What are WebApp Materials?

WebApp Materials are the editable parts of a supplied example, such as HTML, CSS, JavaScript other than the D3pth engine®, configuration, text, graphics, layouts, and templates. They do not include the D3pth engine®, License Notice, third-party materials, or Licensor Marks except where the Licensor expressly states otherwise in writing and has the necessary rights.

Subject to the applicable EULA, WebApp Materials may be used, modified, distributed, commercialised, transferred, sublicensed, and otherwise exploited for any purpose, without restriction to the Licensed Site. Before public deployment or provision outside implementation for the Licence holder, identifiers of D3pth lab s.r.o. and Čeněk Svoboda must be removed from the WebApp Materials. This does not permit any change to the D3pth engine® or License Notice.

Do production licences include the WebApp hit counter?

No. Production licences are issued without the WebApp hit counter or tracking code. The D3pth engine® itself does not require D3pth lab s.r.o. to receive visitor analytics or tracking data from your production deployment.
