Privacy Policy

Privacy Policy

We operate in accordance with the principles set out below:

We undertake to comply with the statutory provisions on data protection and endeavor to always observe the principles of data avoidance and data minimization.

This Privacy Policy applies both to the Vocdoni App (app.vocdoni.io) and to the Vocdoni website (vocdoni.io).

The App includes additional processing activities related to registered users, administrators, and voting processes, while the Website is limited to general information and analytics purposes.

1. The Controller

2. For what purpose do we process your personal data?

When you visit our website, we only process minimal technical data (e.g., IP, browser, device type) necessary for its correct operation and analytics purposes.

We use Google Analytics (with anonymized IP addresses) and Plausible.io for aggregated, non-identifiable analytics.

No personal data is collected for marketing purposes, and no profiling is performed.

We process your personal data to operate the Vocdoni App (hereinafter the «APPLICATION»), which provides secure, verifiable, and privacy-preserving voting and participation processes.

• (a) Administrators: process identification, contact, and authentication data to manage voting processes.
• (b) Voters: process credentials or access codes provided by their organization. Votes are recorded on the Vocdoni blockchain using cryptographic mechanisms ensuring anonymity.
• (c) Technical data: device, browser, and IP may be processed for security monitoring and non-identifiable analytics.

All processing follows the principle of data minimization: only the information strictly necessary to operate the service is collected. Sensitive data is stored in encrypted form to enhance confidentiality and protection.

3. Why can we process your personal data?

The processing of your data is legitimated on the basis of:

• Contractual necessity (Art. 6(1)(b) GDPR)
• Explicit consent (Art. 6(1)(a) GDPR) for optional features
• Legitimate interest (Art. 6(1)(f) GDPR) for security and fraud prevention

4. For how long will we keep your personal data?

• Data of registered users (administrators) and the data uploaded by them (e.g., membership lists) will be kept as long as they maintain their account and contractual relationship with Synergize SL, and thereafter during the applicable legal limitation periods.
• Voters' data remains within the organization's member list database and is never transferred outside of it. Credentials are used solely to generate an address that gives the right to vote and that is not linked to any personal data. Members' data will be retained for as long as the administrator maintains the member list or until the contractual relationship with Synergize SL comes to an end.
• Voters are obfuscated and stored on the blockchain in an immutable and permanent way, without any link to personal data.

When data are no longer necessary for these purposes, they will be deleted with appropriate security measures for complete destruction.

5. To whom do we disclose your personal data?

Your personal data may be disclosed to:

• Public Administrations and authorities when legally required.
• Service providers that need access to personal data to deliver services to Synergize SL (e.g. payment processors, analytics). These providers act as processors under contracts that comply with Article 28.3 GDPR.

6. What are your rights as a registered user?

Your rights include the following, but are not limited to:

• Right to request information in accordance with Art. 15 GDPR
• Right to request rectification under Article 16 GDPR
• Right of deletion of your personal data, provided that further processing is not necessary for any of the reasons stated under Art. 17 GDPR
• Right to request the restriction of processing of your personal data for any of the reasons stated under Art. 18 GDPR
• Right of transmission of your data in a structured, commonly used, and machine-readable format.
