These Terms of Service govern your use of Challenger (the "Service"), operated by Gerd Brunn, Berlin, Germany. By accessing or using the Service, you agree to these Terms.
The Service is provided "as is" and "as available" without any warranties of any kind, express or implied. We make no guarantee of uptime, data availability, or fitness for a particular purpose. We reserve the right to modify, suspend, or discontinue the Service at any time without notice.
You agree not to:
You retain ownership of content you create (progress logs, chat messages, images). By submitting content to the Service, you grant us a non-exclusive, royalty-free, worldwide licence to store, display, and distribute that content solely for operating the Service. You are solely responsible for the content you post.
We reserve the right to suspend or permanently remove any account, with or without notice, for any reason — including but not limited to violation of these Terms. You may delete your own account at any time via the Profile page.
To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or in connection with your use of the Service. Our total liability for any claim shall not exceed the amount you paid for the Service in the twelve months preceding the claim (or zero, if the Service was free of charge).
We may update these Terms at any time. We will indicate the date of the last update at the top of this page. Continued use of the Service after any changes constitutes acceptance of the updated Terms.
These Terms are governed by German law. The exclusive place of jurisdiction for all disputes arising from or in connection with these Terms is Berlin, Germany.
