Terms of Use

Last updated: August 31, 2026

By using PenniTools, you agree to use the website responsibly and in compliance with applicable laws.

Informational tools

PenniTools provides calculators, estimates and utilities for convenience. Results may depend on assumptions, rounding, user inputs, changing rules or third-party data. Check important results before relying on them.

No professional advice

PenniTools does not provide financial, tax, legal, medical, engineering, architectural or other professional advice. Construction calculators are estimates and should be checked against local codes, drawings, site conditions and qualified professionals.

Files and documents

Only upload or modify files that you own or are authorized to process. Keep backups of important documents. Browser processing can be affected by device memory, browser compatibility and file size.

Third-party services

Some features depend on third-party libraries, APIs, content delivery networks or model providers. Their availability, processing and terms may differ from PenniTools.

Availability

We aim to keep PenniTools available and useful, but features may be changed, interrupted, removed or updated without notice.

Limitation of liability

To the extent permitted by applicable law, PenniTools is provided on an “as is” and “as available” basis without guarantees that calculations, outputs or services will always be error-free or uninterrupted.

Changes

We may update these terms as the website develops. Continued use after an update means you accept the revised terms.
