The document contains repeated blanket disclaimers. comdirect accepts no warranty of any kind for the completeness, correctness, or accuracy of the market data, prices, news, and other content, and one data supplier also disclaims all liability. There are no stated exceptions, no carve-out for negligence or intent, and no cap that preserves a remedy. German law would override the worst of this, but the text itself offers you almost nothing if bad data causes you a loss.
comdirect and FactSet claim copyright over the entire website including layout, source code, and content, and you may only retrieve or copy material for private, non-commercial use. Anything beyond that requires prior written consent, and even setting a simple hyperlink to the site from another website is expressly forbidden without written permission, which is unusually restrictive. The document takes no license over your forum posts, which is a small positive.
Bank accounts are not covered here, but community membership is. comdirect reserves the right to delete content, switch it off, and exclude members from the community at any time, with no notice period, no criteria beyond the listed prohibited content, and no appeal process. That is broad discretion, though it only applies to the forums, not your banking relationship.
These are browsewrap website terms. There is no described acceptance step, no checkbox, and no explanation of when you become bound, so you are treated as agreeing just by using the site. The scope itself is stated clearly: the site is for private use by individuals living in Germany, and access from elsewhere is at your own risk.
