Terms of Service

These terms govern your use of TrenchLine Calcs. The most important part is Section 3 — please read it. By using the app, you agree to these terms.

Effective date: June 12, 2026  ·  Operated by Trenchline LLC ("TrenchLine," "we," "us")

01 Acceptance

By accessing or using TrenchLine Calcs (the "app"), you agree to be bound by these Terms of Service and by our Privacy Policy. If you don't agree, please don't use the app.

02 What the app is

TrenchLine Calcs is a collection of calculators and reference lookups for underground utility and general construction work — area, volume, trench, materials, pipe data, and related field math. It's designed to help experienced trade professionals work faster in the field. It is a planning and estimating aid, not an authority.

⚠ Section 3 — Read this

03 Estimates only — not engineering design

Results produced by TrenchLine Calcs are estimates, provided for planning and informational purposes only. They are not engineering designs, not sealed or stamped calculations, and not a substitute for the judgment of a licensed professional engineer, surveyor, or other qualified expert.

You are solely responsible for independently verifying every result — dimensions, quantities, materials, and code compliance — in the field and against your project's stamped drawings, specifications, and applicable codes and standards (e.g. AWWA, ASTM, ASME, OSHA, and manufacturer data) before relying on it.

Do not use the app as the sole basis for any safety-critical, structural, or load-bearing decision. For example, the thrust-block tool estimates concrete volume only — it does not size a block for thrust resistance; required bearing dimensions must come from a qualified engineer's design. Reference and legacy-pipe data should always be confirmed against field markings and authoritative sources.

Construction work carries inherent risk. You assume full responsibility for how you use the app's output.

04 Your responsibilities

05 No warranty

06 Limitation of liability

07 Indemnification

08 Intellectual property

The app, its design, content, calculators, reference data compilations, and the TrenchLine name and marks are owned by us and protected by applicable law. We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the app for your own professional and internal business purposes, subject to these terms.

09 Beta status

The app is currently offered as a beta. That means features may change, be added, or be removed, and the app may occasionally be unavailable or behave unexpectedly. We appreciate bug reports at [email protected].

10 Changes, paid features, and availability

We may modify, suspend, or discontinue any part of the app at any time. Future versions may introduce paid subscriptions or tiers, payment processing, and (on a free tier) advertising. Any paid features will be described at the point of purchase, and any additional terms applicable to them will be presented before you buy. We may revise these terms from time to time; when we do, we'll update the effective date above, and your continued use of the app means you accept the revised terms.

11 Governing law

These terms are governed by the laws of the State of Florida, without regard to its conflict-of-laws rules. You agree that the state and federal courts located in the State of Florida will have exclusive jurisdiction over any dispute arising from these terms or the app, and you consent to venue there.
