Where to upload the config files?

So this is a noob question because I just started making some complex projects from scratch.

I made a script which is basically a application that will be used along with a different software.

I implemented one update feature for the script in which it updates the version and data files. I've uploaded these files in github gist but the link gets changed everytime I revise the file content there.

I don't want to upload the files in a github repository because it will be always publicly available and easy to find.

I don't want complicated hosting things, just wanted to upload the files and generate a link to download them from the server, and easily revise the content there. Please recommend me some good alternative service 😦
