Calculator estimates and limitations

Calculator results are estimates based on your inputs and the stated assumptions. They are not site-specific engineering designs, licensed engineering advice, safety certifications, or code determinations. Verify inputs and results against actual site conditions, applicable requirements, and manufacturer documentation, and involve qualified professionals before making design, safety, purchasing, or operating decisions.

No warranty

LoadCairn and all calculator results are provided ‘as is’ and ‘as available,’ without warranties of any kind, express or implied, including fitness for a particular purpose and accuracy.

Limitation of liability

To the maximum extent permitted by law, LoadCairn and its owner are not liable for any indirect, incidental, consequential or special damages, or for any design, equipment, installation or operating decision made using calculator results. Total liability for any claim is limited to the amount you paid LoadCairn in the 12 months before the claim.

Refunds

You can cancel at any time from Dashboard > Billing. Cancelling stops future charges; payments already made are not refunded except where required by law.

Governing law

These terms are governed by the laws of the State of Florida, USA.
