Creator clarifications

Dear Creator Team,

I am yet to explore "creator" fully but I should admit that I am impressed from what I have seen so far. Good job.

Before I start building my application here, I need the following question answered.

1) what is the guarantee for the security of the data that I enter here?Believe the data will get stored in the database that you guys maintain and the only control which lies with me is my password.That is you guys who developed the apps will still have access to my data.Let me know if my understanding is correct here.

2) Do I have the option of using my own MS Access db as a backend for the application that I build using Zoho?

Regards,
