How to store data on hosting?

Question

MySQL

Guys, I need advice.
There is a simple notepad site for internal use. We are hosted in one large office.
There we write tasks and sometimes confidential information, amounts, calculations, etc.
The point is, I wouldn't really want tech support to have access to this information.
There was an idea to store data in sqlite, because there it is less noticeable, but xs. Maybe you can somehow hide the information in a standard way, even from the TP?

Answer 1

Well, given that you do not have your own server (even the simplest one), then you are clearly not a large corporation that has global secrets.
There is an option - do not bathe. Nobody needs your scribbles.

Answer 2

Encryption?
The same base64 will complicate the task a little. But if you encrypt, it's better to immediately adequately.
