Terms and conditions

The following terms and conditions (the “Agreement”) govern the use of the Klangio website and all content and services available at or through the websites (collectively, the “Service”). The Service is owned and operated by Klangio GmbH at Alter Schlachthof 39, 76131 Karlsruhe, Germany. The Service is offered subject to your acceptance without modification of the Agreement. By accessing or using any part of the Service, you agree to become bound by the Agreement. If you do not agree to all the terms and conditions of this Agreement, please do not use the Service.

This Agreement is between Klangio and you, or any juridical entity that you represent (“you”). If you enter into this Agreement on behalf of another juridical entity, you represent and warrant that you have authority to bind such entity to this Agreement.

Submitted content

You retain the rights to content you submit to the Service. You grant Klangio and its service providers the right to temporarily store and modify your content insofar as necessary to provide the Service to you. Submitted content will be stored for a maximum of 30days.

Content Retraction

Klangio does not host audio or video content of any kind. Audio files uploaded by a user are owned by that user, and are presented only to that user. All transcriptions displayed by Klangio are created automatically by the Klangio transcription algorithm and may be corrected by users or professional music transcribers. No third party transcriptions are displayed or used in any other way by Klangio. Each transcription is specifically created for the respective user. Copyright owners who do not want the transcriptions of their works to be displayed by Klangio can request the retraction of individual songs or composers from the Klangio website by emailing retract@klangio.com. However, any songs removed from the website are at Klangio’s discretion and should not be considered an admission of liability on Klangio’s part.

Quality of Transcriptions

All transcriptions performed by Klangio are created automatically by the Klangio transcription algorithm. Therefore, perfect quality of the transcription can not be guaranteed, and the quality can vary based on the recording conditions (e.g. noise, reverb, echo) and the complexity of the music piece. Klangio is designed to transcribe solo recordings of piano pieces. Having additional instruments or vocals in the recording leads to worse results.

YouTube API

Klangio uses Google’s YouTube API to allow you to search for cover songs on YouTube.
Therefore by using our service, you agree to be bound by the YouTube Terms of Service:

The operating company of YouTube is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, UNITED STATES. The YouTube, LLC is a subsidiary of Google Inc., 1600 Amphitheatre Pkwy, Mountain View, CA 94043-1351, UNITED STATES.
Each time you visit one of our pages that has a YouTube API Client, this creates a connection to YouTube servers.
This informs the YouTube server which of our webpages you have visited.
If you are logged into your YouTube account, it is possible for YouTube to match your browsing behaviour to your personal profile directly.
You can prevent this from happening by logging out of your YouTube account.
We use YouTube in the interests of displaying our online services in an appealing way.
This constitutes a legitimate interest in accordance with Article 6(1f) GDPR.
