I'm not sure that to trust your funds, to pools, is much safer than trusting photos of your documents to startup projects. In addition, I'll tell you the secret, you can correct your data in the photo editor, a little. Ultimately, the main thing that startups need is to know from what country you are, and your name, surname and age, in order to avoid problems with the law. And I'm even not talking about the fact that you need to choose high-quality projects for investment in order to reduce the risk of data leakage. Although you will not get guaranteed security, here you are right. As well as there is no guarantee that banks or cellular companies do not trade your data, or the hotel at vacation, does not do the same.
