Part of the fun of writing code is having other people use it! But before making your code public, you should make sure that it does not contain any secrets.

Where to store secrets
In a file that’s not checked into version control In an environment variable (which you can set in the config file for your shell of choice, either ~/.bashrc or ~/.zshrc)
# ~/.gradle/gradle.properties
