Is the Bubble app secure?

Could you please elaborate on the security features of the Bubble app? I'm considering using it for my cryptocurrency transactions, but I'm concerned about potential security risks. Does the app utilize state-of-the-art encryption methods? Are there any known vulnerabilities or past instances of security breaches? Additionally, how does the app handle user data and ensure privacy? It would be helpful to have a comprehensive understanding of its security measures before making a decision.
