The website does not show anything on how the product is used, which is kind of important for me as a potential customer. Especially if it's going to be effectively handling my copy/pasting of sensitive information.

Does it use some client, what do I need to install on my devices (if supported) and what permissions does it need etc? Instead I'm greeted by a login page.

It's not transparent enough for me how the product is used before signing up and that's a huge turn off.
