Respectfully, in 5 minutes of just being a human using a website your questions are generally answered. Being skeptical is fine, but at least be honest about giving something the time to read it's resources - they have even have a page of useful pages that I found within that first 5 minutes: https://support.diode.io/article/wu3yct3hbn-further-reading

Respectfully, I have tried, but I wasn't able to find the answers either. Your link, in fact, addresses none of the questions raised by the parent comment, the "About" page (https://diode.io/resources/about/) seems broken, and the rest is (to me) rather inscrutable crypto jargon.

Go to the link in the title, scroll down the bottom of the page and the Privacy link is right there, like it is on most website footers. The client is Go open source on github, the security is discussed on the Smart Contracts/Ethereum page and all of that network stuff. That's 3 out of 4 questions, the last one is an opinion.

What? The privacy policy and GitHub are both in the footer.

Plus their How It Works page is pretty informative.

And I've only ever heard of Security Policies used in an organization/company context to ensure employees have good security hygiene.

I can't even see what the end user experience is from the website. All it seems to want you to do is install a random thing without really showing you what you can expect.

Hey there - we'll be posting some videos soon - agree it is not a great experience to have to click or install something without understanding what will happen. Thanks for the feedback.
