Terms of Service
Last updated: October 2026
Using Tiebar
Tiebar is an educational web app for learning construction scheduling. You may use it to learn and practice. Use it lawfully and don't attempt to disrupt, reverse-engineer, or abuse the service or other users.
Accounts
You can use Tiebar as a guest or create an account with your email. You're responsible for the activity on your account. Keep access to your email secure, since sign-in uses magic links.
Educational content, not professional advice
Tiebar teaches scheduling concepts and the Critical Path Method. It is for learning only and is not professional engineering, legal, or project-management advice. Decisions on real projects are your responsibility.
Credentials
Tiebar is not affiliated with AACE International or the Project Management Institute. PSP is a credential of AACE International; PMP and PMI-SP are credentials of PMI. Tiebar does not grant those credentials.
AI features
The AI tutor and Sandbox assistant generate responses automatically and can be wrong. Verify anything important. See the Privacy Policy for how AI messages are processed.
Your content
Sandbox projects and feedback you submit remain yours. By submitting feedback you allow us to use it to improve Tiebar.
Availability and changes
Tiebar is provided "as is" while in active development. Features may change, and the service may be unavailable at times. We may update these terms; continued use means you accept the updated terms.
