End User License Agreement (EULA) — VoltPilot

Version: 1.0 Date: 2026-08-22 Canonical language: English — this version governs worldwide, except in Québec, where the French version governs (see §20.7)

§1 — Parties and subject matter

This End User License Agreement (the "Agreement" or "EULA") is entered into between the developer and owner of the rights in the software, operating under the business name VoltPilot and established in Québec, Canada (the "Licensor", "we"), and the individual or legal entity that installs, activates or uses the VoltPilot software (the "Licensee", "you").

The Licensor can be reached at support@voltpilotpower.com, the single official channel for all purposes of this Agreement, including notices. The Licensor's full civil identification and address are provided, through that channel, to anyone with a legitimate interest — a competent authority, a party to proceedings, or a consumer who requests them. The Licensor undertakes to provide them; what it does not do is publish them indiscriminately.

VoltPilot (the "Software") is a desktop application — today distributed for Windows, and possibly offered for macOS in future — designed to support electrical design work: document review, single-line diagrams, sizing of conductors and protective devices, short-circuit studies, load flow, coordination and selectivity, arc flash, and report generation.

§2 — Acceptance

2.1 By clicking "I accept", installing, activating or using the Software, you declare that you have read this Agreement, understood it, and agree to it in full. If you do not agree, do not install or use the Software.

2.2 If you accept on behalf of a legal entity, you represent that you have authority to bind it, and "Licensee" then means that entity.

2.3 Acceptance is recorded together with the account identification, the document version, and the date and time. The version accepted is the one shown in the header of this file.

§3 — Grant of licence

3.1 Right granted. Subject to payment due and to compliance with this Agreement, the Licensor grants you a non-exclusive, non-transferable, non-sublicensable and revocable licence to install and use the Software, in executable form, for internal professional purposes.

3.2 Scope. The licence is named: it is tied to the user account that activates it. Each licence allows activation on up to one (1) simultaneous device per named user, unless the Plan purchased states a different number. The Plan — features, limits, duration and price — is defined at the time of purchase and prevails over any unwritten expectation.

3.3 Sharing. A named licence may not be used by more than one person. Accounts shared between different professionals breach this Agreement.

3.4 Reservation. All rights not expressly granted are reserved to the Licensor. This Agreement licenses the Software; it does not sell it.

§4 — Activation, verification and offline use

This clause describes how licence control actually works. None of it is incidental: by accepting, you agree to this behaviour.

4.1 Activation. Activation requires an internet connection and ties the licence to the device by means of a machine fingerprint.

4.2 Fingerprint. The Software reads up to four device identifiers, depending on the operating system (on Windows: the system installation identifier, the mainboard identifier, the volume serial number, and an identifier generated on first run), and transmits only cryptographic digests (hashes) of them. The raw values never leave the device and are never written to a log. A device remains recognised as long as at least three of the four identifiers stay the same — replacing a drive or reinstalling the operating system normally does not consume an activation.

4.3 Revalidation. The Software silently revalidates the licence with the server on a daily basis.

4.4 Offline use. You may use the Software without a connection for the tolerance period stated in the licence itself. Once that period lapses without revalidation, the Software restricts access until the next successful verification.

4.5 Clock. The Software detects a backward change of the system clock. In that case the offline tolerance is suspended and online revalidation is required. This is fraud protection, not a judgement about your conduct.

4.6 Fail closed. If the Software cannot verify the authenticity of a licence — including because the installed set of public keys is missing or has been tampered with — it does not open. This behaviour is deliberate.

4.7 Deactivation. You may deactivate a device from within the application or from the account portal, releasing the activation for another machine.

§5 — Evaluation (trial)

5.1 The evaluation, where offered, lasts seven (7) calendar days from activation, is limited to one activation, and is intended solely to evaluate the Software.

5.2 During the evaluation the Software is provided without any warranty and without any support commitment. Once the period ends, access is restricted until a Plan is purchased.

5.3 Attempting to obtain successive evaluations — through multiple accounts, reinstallation, alteration of machine identifiers, or clock manipulation — breaches this Agreement.

§6 — Restrictions

You may not, and may not allow any third party to:

6.1 copy, distribute, rent, lease, lend, resell, host or make the Software available to third parties, including as a service, a calculation bureau, or shared use;

6.2 modify, adapt, translate, or create derivative works of the Software;

6.3 reverse-engineer, decompile or disassemble the Software, except to the exact extent applicable law permits and after prior notice to the Licensor;

6.4 circumvent, disable or interfere with activation, licence verification, clock detection, or any technical protection measure, nor forge machine identifiers;

6.5 remove, obscure or alter copyright notices, trademarks, provenance tokens or version identifiers displayed by the Software or in its reports;

6.6 use the Software, its documentation, its outputs or its catalogues to train, fine-tune or evaluate machine-learning models, or to build a competing product;

6.7 use the Software for any unlawful purpose or contrary to applicable law, including export-control and sanctions rules.

§7 — Intellectual property

7.1 The Software, its code, architecture, interfaces, compiled manufacturer catalogues, calculation engines, documentation and trademarks belong to the Licensor or its licensors, and are protected by law and by international treaties.

7.2 Feedback. Suggestions, defect reports and ideas you send voluntarily may be used by the Licensor without restriction and without compensation. This does not extend to your project data (§8).

§8 — Your data and your projects

8.1 Project files, imported drawings, calculation records, reports and any other content you create or import ("User Data") are yours. The Licensor claims no ownership of them.

8.2 User Data is stored locally, on your device. The Software does not send projects, drawings or calculation results to the Licensor. What travels to the licence server is limited to: account data, hashes of machine identifiers, the Software version, and verification timestamps (§4, and the Privacy Policy).

8.3 Backup is your responsibility. The Software is not a storage service and does not guarantee preservation, integrity or recovery of User Data.

8.4 Termination of this Agreement does not affect ownership of your data; it removes only the right to use the Software to open it.

§9 — Technical standards, catalogues and third-party content

9.1 The Software does not distribute technical standards. Text, tables and figures from the Canadian Electrical Code (CSA), the National Electrical Code (NFPA 70), ABNT NBR 5410 or any other standard are protected works of their respective owners and are not shipped with the Software.

9.2 Import by the Licensee. When you use the Standards Table Extractor to import data from a standards document, you represent and warrant that you hold a lawfully licensed copy of that document and have use rights compatible with the import. You are solely responsible for that use; the Licensor neither authorises nor supervises it.

9.3 Manufacturer data. Curves, catalogues and equipment characteristics reflect information published by manufacturers, incorporated for interoperability purposes and always carried with a provenance token. Trademarks and product names belong to their owners and imply no sponsorship, affiliation or endorsement. Where a manufacturer does not publish a value, the Software declares a gap — it never fills one in on its own.

9.4 Third-party components. The Software incorporates open-source libraries licensed under their own terms, listed in the third-party notice shipped with the installation. In case of conflict, those terms prevail as to the component concerned.

§10 — Nature of the calculations and professional responsibility

This is the most important clause in this Agreement. Read all of it.

10.1 Support tool. The Software is an engineering aid. It is not an engineer, it does not issue technical opinions, it does not seal or sign designs, and it does not replace the judgement of a legally qualified professional.

10.2 Mandatory verification. Every result — conductor and protective device sizing, short-circuit current, load flow, coordination, selectivity, incident energy and PPE selection, voltage drop, loads and reports — must be independently verified by a qualified professional before any use in design, procurement, construction, commissioning, maintenance or energized work.

10.3 Risk to life. Arc-flash and protection-coordination results bear directly on the safety of people. Using them without independent verification may cause serious injury or death. By accepting this Agreement, you acknowledge that risk and assume the responsibility to verify.

10.4 Inputs and assumptions. The quality of a result depends entirely on the data you supply and the assumptions you choose. The Software does not validate the truth of the inputs.

10.5 UNKNOWN is not approval. Where data, a standard or an assumption is missing, the Software declares the gap explicitly. A declared gap never means compliance, approval or acceptance — it means the question remains open and it is yours to resolve.

10.6 Regulatory compliance. The Software helps apply rules from standards, but it does not certify compliance with any code, standard, regulation, utility requirement or authority having jurisdiction. Compliance of the design is the responsibility of the professional in charge.

10.7 Professional responsibility. You are solely responsible for the design you sign, for the decisions you make, and for the results you adopt, publish or deliver to third parties.

§11 — Optional artificial-intelligence features

11.1 The Software offers optional AI-assisted extraction features, which operate only when you configure them.

11.2 If you choose an external provider (for example Anthropic or OpenAI), use is made with your own API key, under your contract with that provider, and the content you submit — including excerpts of project documents — is transmitted to that provider. The Licensor is not a party to that relationship, does not intermediate that content, and is not answerable for how the provider handles it. Consider confidentiality and contractual secrecy obligations before enabling it.

11.3 If you choose local execution, no content leaves the device by that route.

11.4 AI outputs are suggestions, subject to error, and are fully subject to §10.

§12 — Updates, support and evolution

12.1 The Software may offer fixes and new versions. Updates form part of the Software and are subject to this Agreement, unless they come with their own terms.

12.2 Entitlement to new versions follows the Plan purchased and its maintenance period.

12.3 Support, where included, is provided at support@voltpilotpower.com within the limits of the Plan. There is no commitment as to service level, response time, or the correction of any particular defect, save a separate written agreement.

12.4 The Licensor may change, discontinue or replace features in future versions. Paid features still in force will not be removed without an equivalent alternative or a proportional refund.

§13 — Warranties

13.1 The Software is provided "as is" and "as available".

13.2 To the maximum extent permitted by applicable law, the Licensor disclaims all express or implied warranties, including merchantability, fitness for a particular purpose, non-infringement, accuracy, calculation correctness, continuity, and freedom from error or interruption.

13.3 The Licensor does not warrant that the Software satisfies any regulatory, contractual or authority requirement applicable to your work, or that its outputs are correct for your specific case.

13.4 Legal reservation. Some jurisdictions do not allow the exclusion of certain warranties. In those jurisdictions the exclusions above apply only to the extent permitted, and the consumer's non-waivable statutory rights remain intact.

§14 — Limitation of liability

14.1 To the maximum extent permitted by applicable law, the Licensor is not liable for indirect, incidental, special, punitive or consequential damages, nor for lost profits, lost revenue, lost opportunity, loss of data, cost of redesign, work stoppage, rework of an installation, contractual penalties or reputational harm, even if advised of the possibility.

14.2 The Licensor's total aggregate liability, on any cause related to the Software or to this Agreement, is limited to the amount you actually paid for the Software in the 12 (twelve) months preceding the triggering event.

14.3 Reservations. Nothing in this Agreement excludes or limits liability for wilful misconduct, fraud, gross negligence, or death or bodily injury caused by an act of the Licensor, nor any liability that applicable law forbids excluding or limiting.

14.4 The limitations in this clause are an essential element of the economic balance of the Agreement and survive even if a contractual remedy fails of its essential purpose.

§15 — Indemnity

You undertake to indemnify and hold the Licensor harmless from claims, losses and expenses — including reasonable legal fees — arising from: (i) use of the Software in breach of this Agreement or of the law; (ii) import or use of a standards document without a valid licence (§9.2); (iii) use, publication or delivery of results without the verification required by §10; (iv) content you submit to external AI providers (§11).

§16 — Term and termination

16.1 This Agreement runs for as long as your licence lasts.

16.2 You may terminate it at any time by ceasing to use the Software and uninstalling it.

16.3 The Licensor may terminate it for breach — in particular of §3, §4.4 (circumvention of controls), §5.3 and §6 — upon notice, unless the breach by its nature cannot be remedied.

16.4 On termination, the right to use the Software ceases and you must uninstall it. Your User Data remains yours and remains stored on your device (§8.4).

16.5 The following survive termination: §6, §7, §8, §9, §10, §13, §14, §15, §16.5, §20 and §21.

§17 — Price, payment, taxes and refunds

17.1 Prices, currency, billing period and features are those of the Plan purchased at the time of the order.

17.2 Payment processing is handled by Paddle, acting as Merchant of Record (authorised reseller). Purchase, invoicing, applicable taxes and refunds are also governed by Paddle's terms, presented to you at the time of payment.

17.3 Refunds follow the Licensor's policy in force — a 14-day window — and the consumer's non-waivable statutory rights, which prevail.

17.4 Non-payment, chargeback or full refund result in revocation of the licence.

17.5 Subscriptions renew automatically in accordance with the Plan until cancelled from the account portal. Cancellation takes effect at the end of the period already paid for, save any legal provision to the contrary.

§18 — Privacy

18.1 The processing of personal data is governed by the VoltPilot Privacy Policy, which forms part of this Agreement by reference.

18.2 In summary, and without replacing that document: the Software transmits to the licence server only what is needed to issue and verify a licence (account data, hashes of machine identifiers, the Software version, and timestamps). There is no usage telemetry, and projects, drawings and calculation results are not transmitted.

§19 — Export and sanctions

You represent that you are not located in a country subject to an applicable embargo, nor listed on any restricted-party list, and you undertake not to export or make the Software available in breach of applicable export controls or sanctions.

§20 — General provisions

20.1 Assignment. You may not assign this Agreement without the Licensor's written consent. The Licensor may assign it in a corporate reorganisation or transfer of assets, with your rights preserved.

20.2 Entire agreement. This Agreement, the Plan purchased and the Privacy Policy constitute the entire agreement between the parties as to the Software, and supersede prior understandings.

20.3 Severability. The invalidity of one clause does not affect the others; an invalid clause shall be construed so as to preserve its purpose to the extent the law allows.

20.4 Waiver. Tolerance of a breach implies neither waiver nor novation.

20.5 Notices. To the Licensor: support@voltpilotpower.com, the official electronic address for notices, including judicial and extrajudicial notices, to the extent applicable law admits the electronic channel. To you: the email address of your account, a notice sent to it being presumed received.

20.6 Changes. The Licensor may publish new versions of this Agreement. A new version applies from the next acceptance or the next renewal, and does not apply retroactively to a perpetual licence already granted as regards features already delivered. Each version is identified in the header.

20.7 Language. This English version is the canonical version and governs worldwide, except for a consumer domiciled in Québec, Canada, for whom the French version governs and is provided first, as required by the Charter of the French Language. The Portuguese version is a working translation and does not govern. Where any other translation is offered for convenience and diverges, the canonical version applicable to you prevails, save where local law provides otherwise.

§21 — Governing law and forum

This Agreement is governed by the laws of the Province of Québec and the laws of Canada applicable therein, excluding its conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods. The district judiciaire de Montréal is chosen as the forum, save for the forum which the law guarantees to a consumer, which prevails.

Version history

The hash is computed only over the approved and frozen version. A single changed byte — including in this block — produces a different hash. Each language version is a separate file with its own hash, and the record of acceptance must store the hash of the version actually displayed to the user.
