4. Sharing of data between the two companies
So that your KWHN are deducted on your electricity bill, the company selling the KWPN reports to the supplier each month the KWHN and VOLTS that correspond to your supply points, and the supplier informs it of what is needed to manage this. This communication only takes place if you authorise it in “My account”, and you may withdraw it at any time.
5. How long we keep it
- As long as you keep your account or contract and, afterwards, for the legal periods: 6 years for commercial and accounting documentation, 4 years for tax documentation, and the limitation periods for legal actions.
- Contact requests without a purchase: up to 12 months from the last communication.
- Security logs: the time strictly necessary to protect the service and investigate incidents.
6. Recipients
- Between the two companies, on the terms of section 4.
- To the sales agent who assists you, only the essential data (name, contact details, sign-up, power and contract status).
- To public authorities, the CNMC, courts and dispute resolution bodies when required by law.
- To partners that provide services on behalf of the companies, under a data processing agreement, in these categories: billing and customer management; representation in the electricity market and balancing services; energy purchasing; web hosting, cloud database and email sending; payment methods; tax, accounting and legal advice. Partners may change; the safeguards required are always the same.
Stablecoin payments are recorded on public blockchain networks, which we do not control and which do not allow transactions to be deleted.
7. International transfers
Some technology partners may process data outside the European Economic Area. In that case, the transfer is covered by a European Commission adequacy decision, such as the EU-US Data Privacy Framework, or by standard contractual clauses approved by the Commission.
8. Your rights
You may exercise your rights of access, rectification, erasure, objection, restriction and portability, and withdraw your consent, by writing to admin@voltexa-energy.com and stating which right you are exercising. We will ask for what is necessary to verify your identity and will respond within a maximum of one month. You may also lodge a complaint with the Spanish Data Protection Agency (Agencia Española de Protección de Datos) (www.aepd.es).
