This Privacy Policy describes how Carlos Andrés Hernández, CUIT 20-29414660-2 (hereinafter, "Vienor", "we"), with address in the Autonomous City of Buenos Aires, Argentina, collects, uses, stores and protects the personal data of users ("the User", "you") of the Vienor platform, in compliance with Argentine Law No. 25,326 on Personal Data Protection, its Regulatory Decree No. 1558/2001, and other applicable regulations in Argentina. Vienor operates from Argentina and this policy is governed by Argentine data protection law; this English version is provided for convenience and the original Spanish version governs in case of discrepancy.

1. Data Controller

The controller responsible for the personal data collected through the platform is Carlos Andrés Hernández, CUIT 20-29414660-2. For any inquiries regarding the processing of your data, you can contact us at soporte@vienor.com.ar.

2. Data We Collect

We collect the following categories of data:

• Registration data: first and last name, email address, phone number (optional, for WhatsApp notifications), organization name.
• Access credentials: password (stored irreversibly via cryptographic hash), second-factor authentication (2FA) data and passkeys, when the User enables them.
• Service operational data: geographic location and geometry of the fields and plots the User voluntarily uploads to the platform, configured alert rules, field notes, alert history.
• Usage and technical data: IP address, device identifier for push notifications, browser type, pages visited and interaction events with the landing page (proprietary analytics).
• Communications: content of support tickets and, if the User uses the AI assistant, the queries made and the responses generated.

3. Purpose of Processing

The data collected is used to:

• Create and manage the User's account and securely authenticate their access.
• Provide the contracted Service: forecast and alert calculation per field, NDVI visualization, and other platform features.
• Send operational notifications (weather alerts, account confirmation, password recovery) by email, push or WhatsApp, as applicable.
• Provide technical support and respond to inquiries.
• Prevent fraud, abuse and unauthorized access (including anti-bot verification and usage limits).
• Bill for contracted paid plans, when applicable.
• Comply with applicable legal and regulatory obligations.

We do not use the User's personal data for third-party advertising purposes, nor do we sell it.

4. Legal Basis and Consent

The processing of data is based on the consent given by the User upon registering and accepting these Terms, as well as on the necessity of such processing for performance of the Service contract and compliance with legal obligations.

5. Data Processors and Third Parties

To provide the Service, Vienor relies on infrastructure and service providers acting as data processors, including:

• Supabase (database hosting).
• Vercel and Render (web application and API hosting).
• Resend (transactional email delivery).
• OneSignal (push notification delivery).
• Cloudflare (bot protection and content delivery).
• Weather and satellite data providers (Open-Meteo, the Norwegian Meteorological Institute, among others), to whom only the geographic coordinates necessary to calculate the forecast are transmitted, with no identifying data about the User.

These providers only access the data strictly necessary to perform their function and are subject to confidentiality and security obligations. Vienor does not transfer or sell personal data to third parties for purposes other than those described here.

6. International Data Transfer

Some of the providers mentioned in the previous section process data on servers located outside Argentina (including the United States and the European Union). By using the Service, the User consents to such international transfer, which is carried out adopting reasonable security measures required by applicable regulations.

7. Retention Period

We retain personal data for as long as the User's account remains active and for the additional period necessary to comply with legal, accounting or tax obligations, or to resolve disputes. Once account cancellation is requested, the data is deleted or anonymized within a reasonable period, unless it must be retained under a legal requirement.

8. Information Security

We implement technical and organizational measures to protect personal data, including: irreversible cryptographic password hashing, optional two-factor authentication and passkeys, role-based access control, per-organization (tenant) data segmentation, and database-level security policies (Row Level Security). However, no system is completely infallible, and the User is also responsible for keeping their credentials confidential.

9. Data Subject Rights

In accordance with Argentine Law No. 25,326, the User has the right to access, rectify, update and request deletion of their personal data, as well as to revoke consent given. These rights are personal in nature and may be exercised by the data subject, their successors or legal representative, through a request addressed to soporte@vienor.com.ar, providing proof of identity.

The Agencia de Acceso a la Información Pública (AAIP), Argentina's data protection authority under Law No. 25,326, is empowered to handle complaints and claims filed by data subjects regarding breaches of personal data protection rules.

10. Cookies and Similar Technologies

Our landing page uses its own cookies and similar technologies for basic usage analytics (pages visited, traffic source, registration conversion) and for the operation of the anti-bot verification system (Cloudflare Turnstile) on the registration and contact forms. We do not use third-party advertising cookies.

11. Minors

The Service is not directed at minors under 18 years of age. If we become aware that personal information has been collected from a minor without the corresponding consent, we will proceed to delete it.

12. Changes to This Policy

We may update this Privacy Policy periodically. Substantial changes will be notified through the platform or by email. The "Last updated" date shown at the top of this document reflects the current version.
