Terms of use

The rules that apply to the use of the service ARDNTECH during its free beta phase. Read them before creating an account.

Beta version · updated on 17/06/2026

Contents of the Terms and Conditions of Use

01 / Introduction

Contractual framework and beta status.

The two articles below set out the scope of application of these Terms and the special status of the service during its free beta phase. They condition all the other undertakings.

1. Purpose and acceptance

These Terms and Conditions of Use (hereinafter the "Terms") govern access to and use of the ARDNTECH service (hereinafter the "Service"), published by ARDNTECH EI (hereinafter the "Publisher").

Use of the Service implies full and unreserved acceptance of these Terms. If you do not accept all or part of these terms, you must refrain from using the Service.

2. Beta status of the service

The Service is currently offered in a beta version. As such:

  • Access to the Service is free of charge during the beta phase. No financial commitment is required from the user.
  • The Publisher does not guarantee uninterrupted availability of the Service. Planned or unplanned outages are possible, without notice.
  • The Publisher does not provide a contractual service level guarantee (SLA) during the beta.
  • The Publisher may modify, suspend or discontinue the Service at any time, informing users with reasonable notice where this is technically possible.
  • The user is invited to keep a backup copy of their critical data outside the Service during the beta.
02 / Architecture and account

Zero-knowledge and account creation.

ARDNTECH is built on an architecture of end-to-end encryption. This technical choice conditions the respective responsibilities of the Publisher and the user, particularly regarding key management and authentication.

3. Zero-knowledge architecture

ARDNTECH is a secrets vault with end-to-end encryption. All sensitive cryptographic operations (key generation, encryption, decryption) take place in the user's browser. The Publisher's server stores only opaque encrypted data (OpenPGP blobs).

The Publisher has technically no access to the cleartext content of the stored secrets. In particular:

  • The Publisher cannot recover a lost master password.
  • The Publisher cannot respond to a judicial requisition concerning the content of a secret.
  • The loss of the private key downloaded at sign-up renders the secrets permanently inaccessible.

The user is solely responsible for safeguarding their private key. The security page details the cryptographic stack and the formalised threat model.

4. Account creation and authentication

Use of the Service requires the creation of an account. The user undertakes to provide a valid email address and not to impersonate a third party.

The user is responsible for the confidentiality of their credentials and for any activity carried out from their account. Two-factor authentication (2FA) is strongly recommended and enabled by default (email).

03 / Rights and duties

Personal data, undertakings and intellectual property.

The three articles grouped here specify the reciprocal rights and obligations: protection of personal data under the GDPR, rules of use of the Service, and the intellectual property regime applicable to the AGPL-3.0 source code and the editorial content.

5. Personal data

The processing of personal data is governed by the Privacy Policy of the Service, which forms an integral part of these Terms.

The Publisher respects the rights conferred by the General Data Protection Regulation (GDPR): right of access, rectification, erasure, portability, objection. For Business and Enterprise level deployments, a standardised DPA is made available.

6. User undertakings

The user undertakes to:

  • Not use the Service for illegal purposes (storage of unlawful content, money laundering, etc.).
  • Not attempt to bypass the Service's security measures or attack its infrastructure.
  • Not disrupt the operation of the Service (denial of service, aggressive scanning, mass scraping).
  • Report any vulnerability discovered according to the responsible disclosure procedure described on the trust page.

7. Intellectual property

The source code of the Service is made available under the AGPL-3.0 and publicly accessible on the Publisher's GitHub repository. This licence governs the rights of use, modification and redistribution of the software, including for a self-hosted deployment.

The contents of this website (texts, logos, graphics excluding the official logo) remain the property of the Publisher.

04 / Publisher undertakings

Liability, termination, applicable law and contact.

The last five articles frame the Publisher's undertakings regarding liability, termination, amendment of the Terms and applicable law, and indicate the contact channels for any question relating to this document.

8. Liability

The Publisher undertakes to implement reasonable means to ensure the security and availability of the Service. However, owing to its beta status:

  • The Publisher cannot be held liable for data losses resulting from misuse of the Service by the user (loss of the private key in particular).
  • The Publisher cannot be held liable for a temporary unavailability of the Service.
  • The Publisher's liability cannot be engaged for indirect damages (loss of business, loss of opportunity, damage to reputation) resulting from use of the Service.

9. Suspension and termination

The user may delete their account at any time from their settings. Deletion entails the irreversible erasure of their data stored with the Publisher, subject to the legal retention of audit logs (chained HMAC) for traceability purposes.

The Publisher may suspend or terminate an account in the event of a breach of these Terms, after prior notification where possible.

10. Amendment of the Terms

The Publisher reserves the right to amend these Terms at any time. Users are informed of substantial changes by email at least fifteen (15) days before they take effect. Continued use of the Service after that date constitutes acceptance of the new terms.

11. Applicable law and jurisdiction

These Terms are governed by French law. Any dispute relating to their interpretation or performance falls under the exclusive jurisdiction of the French courts, subject to the mandatory rules applicable to consumers.

12. Contact
