I'm an add-on provider for Heroku [1] and if it is they've never communicated it to us.
There's a "What's Orankl" button in the header that shows the following text when clicked:
Orankl is a YC funded company that develops tools for online stores. We focus on reviews systems, smart email marketing and product recommendation engines. We used our own product to add a review system to this site. In case you have a store and want to learn more about us (or in case you want to join our team =) go to orankl.com
You're in violation of their trademark at least. There is nothing, anywhere on that page that suggests that you are not Heroku or acting in concert with Heroku, and you're using their logo and branding heavily.
If they dig up this thread, their lawyers can very easily demonstrate willful trademark violation, which lets them really nail you to the wall if they take you to court.
You know you're in violation of their trademark. Fix it.
