I wanted to show support for his work, and installed the browser and tried it out.

Today I received an email from the developer on my WORK email promoting his IndieGoGo campaign.

The app discovered all the email addresses on my device (which includes my work email) and sent it back for later use.

And there is no unsubscribe option in the email.

first he steals my email address and uses it for marketing purposes without even asking me permission and then he doesnt even provide me with an option to unsubscribe.

This is why I am always hesitant to try new apps or apps that I feel are asking too many permissions. They abuse your trust.
