As a User of the App, you are helping us develop an intuitive, user-friendly, and useful application. We want to hear your feedback on the App, and your ideas are important to us.

When you send, submit, post, or display any User Content such as feedback, survey answers, etc. through our App or any of its services, you assign us any and all non-exclusive license in all intellectual property rights that you hold or may hold in that content and, where not assignable, waive any moral rights you may have for that content.

To that extent, the application of the lending law is agreed, analogously if not directly applicable: We are only responsible for intent and gross negligence. The liability for defects is limited to cases where we fraudulently conceal a legal defect or a defect in the App or its services; in this case we are liable to compensate the User for any damage arising from this.
