These Terms of Sale (« Sales Terms ») govern the subscription to the ARVENS service by professional agents.
Price
The ARVENS subscription is billed according to the plan chosen at registration. Prices are in euros (EUR) and stated all taxes included. ARVENS is published by QUASARIA, a sole proprietorship under the French VAT base exemption regime (article 293 B of the French General Tax Code): no VAT is charged to the client. Invoices will bear the mention « TVA non applicable, art. 293 B du CGI » (VAT not applicable). Prices may be revised; any change will be notified thirty (30) days in advance by email. Changes will only apply from the billing cycle following the notification.
Invoicing and archiving
Invoices are issued in electronic format (PDF) and made available to the agent via their personal area. Pursuant to Article L123-22 of the French Commercial Code and Article 286 of the General Tax Code, ARVENS retains invoices for ten (10) years from their issuance. The agent acknowledges the probative value of electronic invoices in accordance with Article 1366 of the French Civil Code.
Payment terms
Payment is made exclusively by credit card, via Stripe Payments Europe Ltd, an authorised processor. The agent authorises automatic withdrawal of the subscription at each renewal. No bank data (card number, CVV, etc.) is retained by ARVENS.
Duration and renewal
The subscription is concluded for a monthly term, automatically renewed at each maturity for an identical duration, unless previously terminated by the agent under the conditions set out below.
Termination
The agent may terminate their subscription at any time from their management area or by email to contact@arvens.app. Termination takes effect at the end of the current period. No prorata refund is due.
Late-payment penalties and lump-sum indemnity
Pursuant to Articles L441-10 and D441-5 of the French Commercial Code, any late payment automatically and without need for formal notice gives rise to: · late-payment interest, payable from the day following the due date, calculated at the interest rate applied by the European Central Bank to its most recent refinancing operation, increased by ten (10) percentage points; · a lump-sum indemnity for recovery costs of forty (40) euros per unpaid invoice. Where actual recovery costs exceed this amount, ARVENS may claim further compensation, on supporting evidence.
Suspension for non-payment
In the event of payment default at maturity and after a formal notice that has remained without effect for eight (8) days, ARVENS may suspend the agent's access to the service, without prejudice to other rights, including the right to initiate recovery of the debt and penalties. Suspension entails, until regularisation, read-only mode for dossiers, with no possibility of creating new links.
Billing dispute
Any dispute concerning an invoice must be notified to ARVENS by email at contact@arvens.app within a maximum of sixty (60) days of issuance of the invoice. Failing this, the invoice shall be deemed accepted without reservation by the agent.
Right of withdrawal
As the subscription is concluded between professionals (real estate agents acting in the course of their regular business), consumer law provisions on the right of withdrawal do not apply (Article L221-3 of the French Consumer Code).
Legal nature of generated evidence and liability cap
ARVENS provides a technical tool to constitute simple evidence within the meaning of article 1366 of the French Civil Code. The audit PDF report, HMAC logs and NDA acceptances generated by the platform constitute simple evidence whose probative force is assessed sovereignly by the judge. ARVENS provides no legal advice. ARVENS cannot be held liable for the outcome of disputes in which its evidence tools are invoked. The client is solely responsible for the legal context of their use of the platform, for the choice of the NDA clauses they have their buyers accept, and for the appropriateness of resorting, where relevant, to qualified electronic signature mechanisms within the meaning of EU regulation n° 910/2014 (eIDAS). In case of dispute relating to the probative value of a document generated by ARVENS, QUASARIA's liability is capped at the refund of the last twelve (12) months of subscription actually paid by the client, excluding any indirect damages.
Price modification
Any price modification will be communicated to the agent by email with a thirty (30) day notice period. The agent remains free to terminate without charge in the event of disagreement, within the period before application of the new tariff.
Survival of provisions
Termination of the contract, for any reason whatsoever, does not release the agent from payment of sums due as at the date of termination. The provisions relating to intellectual property, confidentiality, limitation of liability, governing law and dispute resolution, as well as the retention of NDA logs already established, survive the end of the contract and continue to produce their effects.
