THE AUTHOR DOES NOT WARRANT THAT ANY EMBEDDED DATA IS CURRENT, COMPLETE, OR FREE OF TRANSCRIPTION ERRORS.

d) Before relying on any Output, You MUST verify all product data against the manufacturer's current official datasheet or catalog, and all anchor data against the current ETA and the anchor manufacturer's own design software and installation instructions.

e) Where the Software identifies the standard edition it implements (e.g., IEC 60364-5-52 Ed. 3.0:2009), You are responsible for confirming that this edition — and not a later edition, amendment, or deviating national annex/local code — applies to Your project and jurisdiction.

7. ENGINEERING DISCLAIMER & PROFESSIONAL RESPONSIBILITY

THIS IS THE MOST IMPORTANT SECTION — PLEASE READ CAREFULLY

THE SOFTWARE IS A COMPUTATIONAL ENGINEERING AID. IT IS NOT A SUBSTITUTE FOR PROFESSIONAL ENGINEERING JUDGMENT, DESIGN REVIEW, INDEPENDENT CALCULATION, OR REGULATORY COMPLIANCE.

7.1 NATURE OF THE OUTPUT

a) All Output is provided for PRELIMINARY DESIGN AND REFERENCE PURPOSES ONLY. Output is generated automatically by applying published formulas and tables to the input values YOU provide; it does not, and cannot, take into account actual site conditions, workmanship, installation quality, environmental factors, or project-specific circumstances not entered into the Software.

b) All Output MUST be independently verified, and where legally required approved, stamped, or sealed, by a qualified professional engineer licensed in the relevant jurisdiction BEFORE being used in any construction, installation, procurement, manufacturing, or safety-related application.

c) The Software's calculation algorithms have NOT been certified, audited, or approved by any professional engineering body, standards organization, notified body, or regulatory authority. Pass/fail verdicts, utilization colors, and warning messages generated by the Software are informational computations, not professional opinions.

d) Output is not a certified, sealed, or signed engineering document. The optional signature block and QR/timestamp features are graphical and cryptographic conveniences only; they do NOT constitute a qualified electronic signature within the meaning of Regulation (EU) No 910/2014 (eIDAS), a professional engineer's seal, or any form of professional certification by the Author.

e) The built-in AI Copilot assistant produces automated informational responses. Its answers may be incomplete or incorrect and must never be relied upon without independent verification by a qualified engineer.

7.2 YOUR RESPONSIBILITIES

The User bears SOLE responsibility for:

a) The accuracy, completeness, and suitability of ALL input data (loads, spans, cable data, dimensions, temperatures, soil parameters, seismic parameters, safety factors, and every other value entered or accepted as a default). Incorrect or incomplete inputs will produce incorrect Output;

b) Independently verifying all Output, including by manual calculation or by comparison with other established engineering tools;

c) Ensuring compliance with all applicable building codes, electrical codes, fire codes, seismic provisions, national annexes, local amendments, and safety standards in force at the project location;

d) Confirming that the standard editions implemented by the Software apply to the project (see Section 6(e));

e) Verifying all manufacturer and anchor data against current official sources (see Section 6(d)); in particular, final anchor selection and verification MUST be performed with the anchor manufacturer's current ETA and design software;

f) Obtaining all necessary engineering reviews, approvals, and permits;

g) Making all final engineering decisions, including the decision to use, adapt, or reject any Output.

7.3 NO PROFESSIONAL SERVICES RELATIONSHIP

a) The Author is a software publisher. The Author does NOT provide engineering, design, consulting, inspection, or other professional services through the Software, its documentation, its support channels, or its AI Copilot.

b) No engineer-client, advisor-client, fiduciary, or other professional relationship is created between You and the Author by Your purchase or use of the Software. The Author is not the engineer of record for any project, assumes no duty of care with respect to any project, and owes no obligations to any third party (including Your clients, contractors, or end users).

c) Technical support answers questions about OPERATING the Software; it does not review, validate, or approve Your designs or inputs.

7.4 PROFESSIONAL USER REPRESENTATION

By using the Software for any purpose other than evaluation, You represent and warrant that You are — or that all Output will be reviewed before use by — a person with the professional qualification, training, and experience necessary to understand, check, and take responsibility for the engineering calculations concerned.

8. ASSUMPTION OF RISK & PROHIBITED HIGH-RISK USE

a) ASSUMPTION OF RISK: You acknowledge that electrical installations and structural supports involve inherent risks (including fire, electric shock, structural failure, and personal injury) and that software-based calculations can never eliminate those risks. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, YOU ASSUME ALL RISK ASSOCIATED WITH YOUR USE OF THE SOFTWARE AND OF ANY OUTPUT.

b) HIGH-RISK USE: The Software is not designed, tested, or licensed for use as the sole or primary design basis in environments requiring fail-safe performance, including without limitation: nuclear facilities, life-support or other critical medical systems, aircraft and air-traffic systems, railway signaling, weapons systems, or any application in which a calculation error could directly lead to death, personal injury, or severe physical or environmental damage ("High-Risk Use").

c) Any High-Risk Use is at Your sole risk and requires — in addition to the obligations in Section 7 — a complete independent design and verification process performed without reliance on the Software. The Author expressly disclaims any liability arising from High-Risk Use.

9. INDEMNIFICATION

To the maximum extent permitted by applicable law, You agree to indemnify, defend, and hold harmless the Author from and against any and all claims, demands, actions, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) brought by You or by any third party (including Your clients, employers, contractors, insurers, or persons suffering injury or damage) arising from or related to:

a) Your use of, or inability to use, the Software or any Output;

b) Any engineering, procurement, construction, or installation decision made in reliance on the Software or any Output;

c) Any breach by You of this Agreement, including of Your verification obligations under Sections 6 and 7;

13.5 EU CONSUMER RIGHTS

In accordance with the EU Consumer Rights Directive (2011/83/EU), EU consumers acknowledge that by activating the license key, they consent to immediate access to digital content and understand that this may affect their statutory right of withdrawal. A 14-day withdrawal right is provided regardless (see 13.1/13.2/13.3 above).

14. PRIVACY & DATA PROTECTION

a) LOCAL PROCESSING BY DEFAULT: The Software performs all calculations locally on Your computer. Project files, calculation results, and engineering data are stored locally and are NOT transmitted to any external server, except in the specific, user-visible cases listed below and in Section 15.

b) AI COPILOT IS FULLY LOCAL: The built-in AI Copilot is a local rule-based calculation assistant. It does NOT connect to any external artificial-intelligence service; Your questions and chat history never leave Your computer (history is stored in a local file).

c) LICENSE VERIFICATION: When activating or verifying a license, the Software transmits to the Author's license server:

- Your license key

- A hardware-derived Computer ID (anonymous one-way hash — not reversible to identify hardware components)

- Software version number No project data is transmitted during license verification.

d) WEATHER DISPLAY (home screen): To show local weather and suggest an ambient temperature, the Software may contact two third-party services: an IP-based approximate-location service (ipwho.is) and a weather service (open-meteo.com). As with any internet request, Your IP address is technically visible to these services, which act as independent controllers under their own privacy policies. No project data, personal identifiers, or license information is sent. If no internet connection is available, the feature is silently skipped.

e) ONLINE SHARE (user-initiated only): If You explicitly use the "Share Online" feature, a snapshot of the selected calculation section is uploaded to the Author's share endpoint and a short link is returned. Shared snapshots expire and are automatically deleted after approximately 90 days. ANYONE WHO OBTAINS THE LINK CAN VIEW THE SHARED SNAPSHOT — do not share confidential project data. No project is ever uploaded automatically.

f) TIMESTAMP PROOF (user-initiated only): If You use the document timestamping feature, only a cryptographic hash (digest) of the document is transmitted to public OpenTimestamps calendar servers. The document itself never leaves Your computer, and the hash cannot be reversed to reconstruct its content.

g) CRASH REPORTS: The optional crash report feature allows You to voluntarily send error reports via email. Crash reports contain the error type and traceback, Software version, operating system, and tray configuration at the time of error (dimensions only, no personal data). No crash data is ever sent automatically.

h) GDPR COMPLIANCE (EU Users): As the data controller for license verification and the share endpoint, the Author (Akin Turcan, Belgium) informs EU users that:

- Legal basis for license verification: legitimate interest (license enforcement) per GDPR Article 6(1)(f)

- Legal basis for user-initiated features (share, timestamping, crash reports): performance of the contract / Your request, per GDPR Article 6(1)(b)

- Data retention: license verification data is retained for the duration of the license; shared snapshots for ~90 days

- Your rights under GDPR Articles 15-22: access, rectification, erasure, restriction, portability, and objection

- To exercise these rights, contact: info@simulate-software.com

- You may lodge a complaint with the Belgian Data Protection Authority (GBA/APD): www.dataprotectionauthority.be

i) NO TRACKING: The Software does not use cookies, analytics, telemetry, advertising identifiers, or any form of usage tracking.

15. ONLINE SERVICES

a) Certain features depend on online services: license activation and verification, floating-seat management, Online Share, weather display, and timestamp proof (together, "Online Services").

b) Online Services are provided on an "as available" basis. The Author may modify, suspend, or discontinue any Online Service (other than license verification for active licenses) at any time. Third-party services used by the Software (see Section 14(d) and 14(f)) are outside the Author's control.

c) The Software remains fully functional for local calculation work without an internet connection, except for features that inherently require connectivity (activation, floating seats, share, weather, timestamping).

17. FORCE MAJEURE

The Author shall not be liable for any failure or delay in performance due to causes beyond reasonable control, including but not limited to: natural disasters, war, terrorism, pandemic, government actions, power failures, internet outages, or third-party service disruptions. This includes, without limitation, any inability to provide license verification or other Online Services.

18. GOVERNING LAW & DISPUTE RESOLUTION

a) This Agreement shall be governed by and construed in accordance with the laws of Belgium, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods (CISG).

b) Any disputes arising out of or in connection with this Agreement shall first be attempted to be resolved through good-faith negotiation.

c) If negotiation fails, disputes shall be subject to the exclusive jurisdiction of the courts of Antwerp, Belgium.

d) CONSUMER PROTECTION: Nothing in this Agreement shall limit any mandatory consumer protection rights that You may have under the laws of Your country of residence. If You are an EU consumer, You may bring proceedings in the courts of Your Member State of domicile.

19. ASSIGNMENT

a) You may not assign or transfer this Agreement or Your license without the prior written consent of the Author.

b) The Author may assign this Agreement to a successor entity (e.g., in the event of a company formation, merger, or acquisition) without Your consent, provided that the successor agrees to be bound by the terms of this Agreement.

20. MODIFICATION OF TERMS

a) The Author reserves the right to modify this Agreement at any time.

b) Material changes will be communicated through the Software (e.g., upon update installation) or via the email address associated with Your license.
