3) DEFINITIONS“Outputs” means any calculation, metric, graph, simulation, suggestion, report (including PDF export), diagram, table, data or result produced by the App.“Project Data” means any room dimensions, layouts, material selections, notes, and settings you enter or store.“Material Library” means any database of absorption coefficients, gas flow resistivity (GFR), densities, or other material properties shown in the App.“Standards” means any preset targets, guidance curves, or references (including ITU/EBU/DIN presets) that may be selectable in the App.
‍
4) ELIGIBILITY AND ACCEPTANCE4.1 You must be at least 18 (or the age of majority where you live) or have consent from a parent/guardian if legally required.4.2 These Terms form a binding agreement between you and the Provider when you download, access, or use the App.4.3 If you use the App on behalf of a company or client, you confirm you have authority to bind that organisation, and “you” includes that organisation.
‍
5) LICENCE GRANT (YOUR PERMISSION TO USE THE APP)5.1 The App is licensed, not sold. We grant you a limited, non-exclusive, non-transferable, revocable licence to install and use the App for your own lawful purposes on devices you own or control, subject to these Terms and any applicable platform usage rules (e.g., Apple App Store rules).5.2 Except as permitted by law, you must not: copy, reverse engineer, decompile, attempt to derive source code, modify, create derivative works, distribute, resell, rent, lease, lend, or make the App available over a network where it could be used by multiple devices simultaneously (unless your licence explicitly permits this).5.3 We may offer different licence tiers (e.g., free/trial/pro). Any additional terms shown at purchase/activation form part of these Terms.
‍
6) THE APP’S PURPOSE, LIMITATIONS, AND ASSUMPTIONS6.1 The App provides tools including, without limitation:Room analysis metrics (e.g., volume, surface area, Schroeder frequency, required absorption);Per-band RT60 target curves and absorption planning;3D layout tools, reflection visualisation, modal response modelling/visualisation;Absorber calculators (porous/panel/Helmholtz/multi-layer);Reporting and utilities (including PDF export) and optional iCloud sync.6.2 All Outputs are estimates. Acoustics is sensitive to variables including (non-exhaustive): construction stiffness, boundary conditions, flanking paths, leakage, installation quality, HVAC noise, temperature/humidity, furnishing, occupancy, speaker directivity, diffraction, source spectra, measurement position, and material tolerances. The App cannot fully model all of these.6.3 Material Library limitations: Material data can vary by manufacturer, batch, mounting, air gaps, edge conditions, ageing, frequency resolution, lab method, and installation. Treat Material Library values as indicative unless verified by current manufacturer/lab data and your specific mounting detail.6.4 Standards/presets limitations: Selecting a preset or target does not guarantee compliance with any standard. Standards interpretation and compliance typically require broader context and measurement.
‍
7) YOUR RESPONSIBILITIES (YOU CONTROL THE INPUTS AND DECISIONS)You agree that you are responsible for:7.1 Ensuring your room dimensions, geometry, speaker/listener placement, damping inputs, and material data are correct.7.2 Verifying Outputs through appropriate professional methods (including, where appropriate, on-site measurement and competent design review).7.3 Ensuring any design, procurement, construction, or operational use complies with applicable laws, regulations, building codes, contracts, health & safety duties, and project requirements.7.4 Using appropriate hearing-safe practices: the App does not control your monitoring levels; you remain responsible for safe exposure.
‍
8) NO PROFESSIONAL ADVICE / NO RELIANCE8.1 The App is provided as a general guidance tool. It does not provide professional advice (acoustic, engineering, architectural, legal, regulatory, medical, or otherwise).8.2 You must not rely on Outputs as the sole basis for decisions where failure could cause loss, damage, injury, contractual breach, or regulatory non-compliance.8.3 If you need verified performance outcomes, you should engage an appropriately qualified professional and conduct appropriate measurement and validation.
‍
9) REPORTS, EXPORTS, AND SHARING9.1 Reports (including PDF exports) are generated from your inputs and the App’s modelling assumptions.
