Account security

You must protect your login credentials, use the application only through your assigned account, and promptly report suspected unauthorized access. You are responsible for activity performed through your account except where caused by our failure to apply reasonable safeguards.

TwelveSpec and its licensors retain all rights in the application, workflows, branding, documentation, and software. Customer, vendor, accounting, and operational records remain subject to applicable ownership rights and business agreements.

Availability and changes

We may update, suspend, or discontinue features to maintain security, reliability, compliance, or business operations. We do not guarantee uninterrupted availability.
