Please read these terms carefully before using VSME OS. By creating an account or using the service, you agree to be bound by these terms.
These Terms of Service ("Terms") constitute a legally binding agreement between you ("User", "you") and VSME OS ("VSME OS", "we", "us"), governing your access to and use of the VSME OS platform at vsmeos.fr ("the Service").
By registering an account, clicking "I Agree", or otherwise accessing the Service, you confirm that you have read, understood, and agree to these Terms in full. If you are accepting on behalf of a company, you warrant that you have the authority to bind that company to these Terms.
If you do not agree to these Terms, you may not access or use the Service.
Note: VSME OS is currently pre-incorporation. These Terms will be amended to reference the registered legal entity (with SIRET number) immediately following incorporation, with reasonable advance notice to active users. All obligations in these Terms remain binding in the interim.
VSME OS is a B2B software-as-a-service (SaaS) platform that enables small and medium-sized enterprises ("SMEs") to measure, calculate, and report their greenhouse gas (GHG) emissions in accordance with recognised standards including:
The Service includes: carbon footprint calculation engine, Scope 1/2/3 data entry forms, automated PDF report generation, evidence file vault, buyer dashboard, and supplier invitation system.
We reserve the right to modify, suspend, or discontinue any aspect of the Service at any time, with reasonable notice to active subscribers.
You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You must notify us immediately at legal@vsmeos.fr if you suspect unauthorised access.
You warrant that all activity data, company information, and supporting documents you provide are accurate, complete, and relate to the entity and reporting period you have declared. Providing knowingly false or misleading data to generate a carbon report is a breach of these Terms and may constitute fraud under applicable law.
You agree not to:
The Service is currently offered free of charge. Paid subscription plans — including billing, refunds, and payment processing — will be introduced in a future release of VSME OS.
When paid plans launch, users will be notified by email and in-app notice at least 30 days in advance, and these Terms will be amended to include the applicable pricing, billing terms, and consumer protection rights under EU and French law (including the 14-day right of withdrawal for annual subscriptions).
Until paid plans are introduced, no clauses in this Section 4 apply, and no payment obligations arise from your use of the Service.
All intellectual property in the VSME OS platform — including the software, calculation engine, emission factor database, UI design, and generated report templates — is owned by or licensed to VSME OS. You are granted a limited, non-exclusive, non-transferable licence to use the Service during your subscription period.
You retain ownership of all data, documents, and information you upload to the Service ("Your Content"). You grant VSME OS a limited licence to process Your Content solely to provide the Service. We will never use your company emissions data for purposes other than generating your report and improving the calculation engine (in anonymised, aggregated form only).
PDF reports generated by the Service are owned by you. You may share them freely with buyers, auditors, regulators, or any third party for any lawful business purpose.
Important disclaimer — please read carefully.
VSME OS provides a calculation tool. The accuracy of generated reports depends entirely on the accuracy of the activity data you provide. VSME OS does not independently verify the data you enter. Reports are self-attested (limited assurance) unless you separately engage a third-party verifier.
Emission factors used in calculations are sourced from recognised national databases (ADEME, DEFRA, EPA, IEA, etc.) and are updated periodically. We make reasonable efforts to keep factors current but cannot guarantee they reflect the most recent published values at all times. Factor sources and update dates are disclosed in each generated report.
Generated reports are not a substitute for independent third-party verification where such verification is required by regulation, contract, or buyer specification. Buyers relying on supplier reports for CSRD Scope 3 disclosures should conduct appropriate due diligence.
To the maximum extent permitted by applicable law:
Nothing in these Terms excludes or limits liability for fraud, death or personal injury caused by our negligence, or any other liability that cannot be excluded under applicable French or EU law.
You may close your account at any time from the account settings page. Your data is retained for 90 days after closure, during which you may request export of your assessment data and reports. If paid subscription plans are active at the time of closure, cancellation takes effect at the end of the current billing period in accordance with Section 4.
We may suspend or terminate your account immediately if you materially breach these Terms (including providing fraudulent data), fail to pay, or if we are required to by law. We will give reasonable notice where practicable.
On termination, your licence to use the Service ends. Previously generated PDF reports remain your property. Data deletion timelines follow our Privacy Policy (Section 5).
These Terms are governed by and construed in accordance with the laws of France, without regard to conflict of law principles.
For B2B disputes, the parties agree to the exclusive jurisdiction of the Commercial Courts of Paris (Tribunal de Commerce de Paris).
For disputes involving consumers (natural persons acting outside their trade or profession), mandatory EU consumer protection laws apply and may provide additional rights.
