Hi Dominik,

Thanks for the positive feedback!

Are we allowed to sell our app in the Google PlayStore, when it's using your API?

Yes, you are. Just be sure to properly attribute TMDb as the source of the data and/or images you use.

I've read the Terms of Conditions and Use and there was written that you can add a fee for the API usage. Will you contact the users if that happens?

Yes, we would but we don't charge for any usage at this time. We also don't have any plans on changing that anytime soon.

Also is it enough to include the TMDb logo and stuff in an "About..." or "Credits" part or are there more specific regulations?

Yes, that is enough. We like to see a link off of the main detail pages where possible but that is not a firm requirement.

Cheers.
