Does my app get uploaded to expo when creating a build?

Question

I just created a build with expo. I monitored the building process closely. Since it was not a final release build I selected the option that expo handles the keystore. After that I saw a couple of messages that made me think if my code got uploaded to Expo.

This is the console stack trace:

[07:10:44] Publishing to channel 'default'...    //What does the publishing mean? Is this going to be publicly available?
[07:10:46] Building iOS bundle
[07:11:28] Building Android bundle
[07:12:18] Analyzing assets
[07:12:22] Uploading assets
[07:12:24] Uploading /assets/refund-title.png
[07:12:24] Uploading /assets/drawer-cover3.jpg
[07:12:25] Processing asset bundle patterns:
[07:12:25] - /Users/bbh/Coding/React Native Apps/refundtracker_expo/**/*
[07:12:25] Uploading JavaScript bundles         //My code gets uploaded to expo, why?
[07:12:41] Published

On the expo website I followed the building process and saw at the end the following:

...
uploading build artifact to S3
...

I just wanted to ask if my code is now publicly available or if the code just got uploaded to the expo servers for processing the build and ultimately uploaded to S3 to make the build available for me on their website. Or did my code got uploaded and is now somehow available to other people? Maybe somebody from expo can answer.

Answer 1

This from there official document Expo

The default privacy setting for Expo apps is unlisted so nobody can find your app unless you share the link with them.

And the code is not publicly available. So, you don't need to worry about that.
