How to sign a confidentiality agreement with a freelancer without other contracts?

Question

Freelance

Good day everyone!
Context:
I want to connect a programmer to a small project. The value is the database collected by the parsers. It can be sold, and more than once, for good money.
Task:
1. It is necessary to minimize the probability of theft of the database and source code.
I came to the conclusion "if a person is rotten, he will still steal." Therefore, I found a candidate in my city, I want to meet in person and sign a confidentiality and non-disclosure agreement before starting work.
2. I (IP) do not have employees and do not want to complicate reporting with official hiring.
Questions:
1. Share the agreement that you signed (if you have such experience).
2. How to sign an agreement without hiring a person (without an employment contract, an employment contract)? And if you hire, then it is necessary so that it does not appear as an employee. Moreover, the payment is piecework.

Answer 1

Such an agreement will have no special force. Well, if he violates it, the database will leak, it is necessary to prove that it was he who violated it, etc.

Answer 2

Mikhail Petrov : You yourself gave the answer ->

one writes on the test with dummy data, and the other releases on the combat

And this is the best option!

Answer 3

The project is divided into small parts, they do not give access to the entire project and to the full database, but only to the test one.
This guarantees you much more seriously than a signed contract.
