Privacy policy

Who is responsible

The controller of your personal data is me, Juan Carlos Sacristán Antoni, as the owner of juansacri.com.

Contact email: juan@juansacri.com

What data I collect and why

1. Contact form

If you write to me through the contact form I collect: name, email, organisation (optional), reason and message. Purpose: reply to and address your request. Legal basis: your consent when submitting the form. Retention: the time needed to resolve your enquiry, and if it leads to collaboration, for the duration of the relationship.

2. "Energy letters" newsletter

If you subscribe to the newsletter I collect: name and email. Purpose: send you my reflections on energy communities, cooperativism and energy transition once a month. Legal basis: your explicit consent. Retention: until you unsubscribe (each email has an unsubscribe link).

Who else sees your data

I use FormSubmit.co as data processor for forms and newsletter. Emails arrive directly at my personal Google (Gmail) account. No other company accesses your data.

I don't sell your data. I don't share it with third parties for commercial purposes. And I don't use it to profile you.

Your rights

You can exercise the following rights at any time:

• Access — know what data I hold on you.
• Rectification — correct inaccurate data.
• Erasure — ask me to delete your data.
• Objection — ask me to stop processing it.
• Portability — receive your data in a structured format.
• Restriction — restrict processing.

To exercise them, write to juan@juansacri.com. I'll reply within 30 days, usually much sooner.

If you believe I haven't handled your data correctly, you can lodge a complaint with the Spanish Data Protection Agency (AEPD).

Security

I apply reasonable technical measures to protect your data: the site is served over HTTPS, forms include anti-spam protection, and emails are handled in accounts with two-factor authentication.

Changes to this policy

If I update how I handle your data, you'll see it here. Last revision: April 2026.
