Terms of use

Lagging Maven · Updated September 27, 2026

Lagging Maven is licensed under Apple’s Standard Licensed Application End User License Agreement. This page explains the subscription and engineering-use scope; it does not replace that agreement or remove non-excludable rights under applicable law. App Store release is in preparation.

One monthly plan

Lagging Maven Monthly unlocks installation planning, material quantities and costing, lagging studio, engineering-analysis workspaces and their exports on supported Apple devices. The planned U.S. price is US$5.00 per month. Local storefront prices vary. The App Store displays the price, billing period and applicable offer before you confirm a purchase.

14-day free introductory trial

Eligible new subscribers receive 14 days of subscription access without charge. Apple determines eligibility; there is one introductory offer per subscription group. Reinstalling the app or changing devices does not create another trial. After the trial, the subscription automatically renews monthly at the price Apple displayed when you subscribed unless canceled.

Renewal, cancellation and refunds

Subscriptions renew automatically unless canceled. Manage or cancel through Apple’s subscription settings. Cancel at least 24 hours before the trial ends to avoid a charge. Apple controls the effective cancellation date and whether access continues after cancellation of a trial. Deleting the app does not cancel billing. Direct purchase and refund requests to Apple.

Project files and device access

An active subscription is required for the planning, analysis and export workspaces. Opening and saving project files, the overview and model documentation remain available without an active subscription. Subscription expiry does not delete your project files. Use the same Apple Account to restore subscription access on your devices. Save and transfer projects using the file locations you choose; automatic Maven cloud synchronization is not included.

Engineering and installation scope

Lagging Maven is a planning and engineering aid. You supply and verify the dimensions, material properties, costs and applicable manufacturer instructions. Examples and default values are illustrative, not certified designs, supplier specifications or approved installation procedures.

Independently verify inputs, assumptions, results and suitability for the application. Obtain qualified engineering review, supplier instructions and site approval before manufacture, installation, operation or maintenance. The app does not certify bond strength, fatigue life, safe operating limits or fitness for service, and does not automatically authorize a pulley’s release.

The current job workflow covers cylindrical shells, supported full-wrap sheets and full-face axial strips, and autoclave material planning. Animations illustrate entered process information; they are not supplier-qualified procedures or photorealistic process simulations.
