I don’t want to create “login users system”?
I have not any host?
Please Help me

Firebase is a free hosting for small apps. You can try that.

It is impossible to help you without knowing what kind of data you want to store or how do you intend to access it.

How to use?

some numbers
for example:

*Date : 6/24/2020*
*Time : 10:00:00*
*Temperature1 : 120*
*Temperature2 : 137*
*Temperature3 : 100*
