cloud.vonwangelin.com looks like a personal cloud or test project, not a business. For that kind of site, missing contact info and legal pages are normal. The real problem is the security: the SSL certificate runs out tomorrow, and the server still supports old encryption methods that are known to be weak. That means your connection to this site could be intercepted or blocked by your browser. There's no history in the Wayback Machine and no social media presence, so you can't check if this site has been around long or if others have had issues. If you're just browsing a personal file, the risk is low. But if you're thinking about uploading anything private or logging in, wait until the certificate is renewed. Ask yourself: is cloud.vonwangelin.com a scam? Probably not, but it's a neglected site that shouldn't be trusted with anything important right now.
