This site lives under the zdusercontent.com domain, but that's about all we can say for certain. It has no visible contact information, no about page, and no privacy policy or terms of service. The homepage itself returns a 422 error, meaning it isn't rendering a usable page right now. For any site that expects visitors to share data, download files, or interact in some way, these are significant missing pieces.
We checked for reviews of 24475.apps.zdusercontent.com and found nothing on Trustpilot, no Wayback Machine history, and no social media accounts. That's an unusually blank slate. A legitimate content delivery or app platform would typically have some kind of support page or documentation visible.
Is 24475.apps.zdusercontent.com a scam? We can't confirm it is, but the evidence is stacked against it being a trustworthy site. The combination of anonymity, missing legal pages, and a non-functional homepage means there's no reason to assume good faith here. Our advice: don't enter any data or follow any links from this site until it shows clearly who runs it and what it does.
