Terms of Service

Effective Date: February 2026 • Last Reviewed: November 2026 (Draft, needs legal review)

1. Material Takeoff Disclaimer & Construction Notice

The materials calculations, board counts, courses, linear footage estimates, fastener counts, panel adhesive tubes, and cost ranges generated by Shiplap Calculator are provided for preliminary architectural planning and budgeting purposes only.

Physical construction environments vary significantly. Factors including out-of-plumb walls, non-level ceilings, irregular framing stud spacing (e.g., non-standard 16" or 24" O.C. layouts), lumber mill planing deviations (±1/32" to ±1/16"), local building code amendments, and jobsite cutting errors can alter required material quantities.

Mandatory Jobsite Verification: Always physically measure actual room framing and verify municipal building code compliance before placing non-refundable lumber or millwork orders. Shiplap Calculator assumes no liability for material shortages, project delays, or excess inventory resulting from field variances.

2. Free Access & Fair Use License

Shiplap Calculator grants you a personal, worldwide, non-exclusive, revocable license to access and use our interactive calculators, 2D visualizers, and educational guides free of charge for personal DIY projects, academic study, and commercial contractor estimation.
