Your Content

Nothing in these terms gives the centre any ownership rights in intellectual property that you share with the platform, such as your account information, posts, or other content you submit to the platform.

Between you and the centre, you remain solely responsible for content you submit to the platform.

That special license allows the centre to copy, publish, and analyze content you submit to the platform.

When content you submit is removed from the platform, whether by you or by the centre, the centre’s special license ends when the last copy disappears from the centre’s backups, caches, and other systems.

If the centre fails to notify you of a legal claim promptly, you won’t have to indemnify the centre for damages that you could have defended against or mitigated with prompt notice. You agree to allow the centre to control investigation, defense, and settlement of legal claims for which you would have to indemnify the centre, and to cooperate with those efforts. The centre agrees not to agree to any settlement that admits fault for you or imposes obligations on you without your prior agreement.
