Nah, we would never steal any key.

As this is a project just for fun, totally FREE and people might use it a lot, we don't want to spend a ton of money just for fun.

We have some other projects that ask for the key after the trial, like

https://roadtripnavigator.com/

https://askfamouspeople.com/

and others.

If you want to, check out http://samedayskunkworks.com to view all of our projects that we do just for fun ;)

Also recommend open sourcing the code so everyone can see that API keys aren't being stolen
