We uninstalled the app and a campaign still stayed on the product page. Thank goodness we made a duplicate of our theme. Needs more functionality for the price. Should have more options. It does EXACTLY what it showcases on the demo and that's about it. It is not worth the money, in our opinion.
Thank you for considering our app for your store and for sharing your experience so we can learn from it.
To protect merchants from mistakes and bad actors, when uninstalling an app in Shopify, all apps simply lose their access to your store. No code is changed or removed on uninstall. For Crowdfunder, we have a quick solution: re-install Crowdfunder to restart your free trial, delete your existing campaigns, then uninstall Crowdfunder again. (You should have received an email with these instructions immediately on uninstall as well.)
As for the app doing exactly what its advertised to do and nothing more, our policy for choosing new features is to to pick the ones which will bring the most value to as many of our customers as possible. We're a really small team with a long list of ideas. If you'd like to submit a feature request, we'll try to add your feature after we've received a few other similar requests.
Hope that helps!
