Do you have more detail? Like a lot more? And are you being regularly audited by a third party?

Saying "we use a similar approach to Cloak AI" isn't good enough for many reasons. They don't provide a lot of detail to begin with, so it's unclear their approach is proven. And you're not even using their approach, just a similar one.

Even if we had a long whitepaper about how you do things, that's still not good enough because we don't know that you're actually doing it. That's why the audit is important.
