What design elements make you trust an app with your sensitive information?

Hi I’m a senior working on my capstone and I’m researching how users perceive trust when interacting with apps that handle sensitive information, such as legal or financial data.

I’d love to hear your thoughts on what specific design choices—whether it’s UI elements, security indicators, or overall user experience—make you feel confident in an app’s trustworthiness.

Thank you for your replies in advance✨
