Copying someone else's website layout without permission may potentially violate copyright laws, intellectual property laws, or terms of service. Copyright protects original works of authorship, including website layouts and designs. If you have created a unique and original layout for your website, it may be protected by copyright.
However, it's important to note that copyright protection is not automatic. In many countries, copyright is granted upon creation of the work, but it may be a good idea to register your copyright with the appropriate authorities in your jurisdiction for added protection.
As for how the new company got access to your files without your permission, it's difficult to provide a definitive answer without more information. However, here are a few possible scenarios:
1. Unauthorized access: If someone gained unauthorized access to your Webflow account or files, they may have been able to copy your website layout.
2. Publicly accessible layout: If your website layout was publicly accessible, it is possible that the new company simply viewed your website and replicated the design. In this case, the issue may not be a violation of copyright if your design was not protected.
3. Breach of agreement: If there was a breach of agreement or violation of terms of service with Webflow, it's possible that your files were accessed or shared without your permission. In such cases, you may want to reach out to Webflow support for assistance and report any unauthorized access.
It's crucial to gather evidence and consult with a legal professional to determine if your rights have been violated or if any legal action can be pursued. They will be in the best position to assess your specific circumstances and provide appropriate guidance.
