These terms cover your use of portfolio.ppvnx.com, Leo Zhu's personal portfolio site and its browser demos. By using the site you agree to them.
A personal showcase, offered free of charge, with no account required. It is not a commercial service, carries no uptime promise, and any page or demo may change or disappear at any time.
Use the demos for your own experimentation. Do not submit unlawful content or anyone else's personal data, do not attempt to break into, overload or scrape the site at automated volume, and do not resell access to the demo endpoints. We may rate-limit or block traffic that harms the service for everyone else.
You keep every right in the images and text you feed a demo, and we do not retain them — see the Privacy Policy. You confirm you have the right to submit whatever you upload.
The site's code, writing, photographs and artwork are Leo Zhu's, except where a page credits someone else. Do not republish them without permission. Third-party libraries and models remain under their own licences.
The site and its demos are provided "as is", without warranty of any kind. Model predictions are illustrative and frequently wrong; do not rely on them for any decision that matters. To the extent the law allows, we are not liable for any loss arising from your use of the site.
If these terms change, the "last updated" date above changes with them. Continued use after a change means you accept it.
