What we collect

• Newsletter data you submit (email, consent timestamp).
• Navigation cookies if you allow them (to improve content and experience).
• Basic technical data (IP/UA) processed for security and abuse prevention. When we use geolocation, we store only city/region/country (not the raw IP).

Third-party services

• Google Analytics: traffic and performance metrics (only with consent).
• Resend (newsletter): email delivery for subscribers.
• GitHub: displaying public repository data.

How we use your data

• To send the newsletter you opted in to receive (with confirmation).
• To analyze and improve site performance when you allow analytics.
• To maintain security, prevent abuse, and comply with legal obligations.

Legal basis (GDPR)

• Consent: analytics and newsletter.
• Legitimate interest: security, abuse prevention, and site functionality.
• Contract performance: when responding to direct inquiries.

Cookies and analytics

We only use non-essential cookies if you allow them. You can change your preferences at any time.

Sharing with third parties

We do not sell your data. We may use essential services (email delivery and analytics) that process data under privacy safeguards.

External links and third-party content

Some posts may include links to third-party websites (e.g., YouTube and reference articles). When you click, you are redirected to a service outside our control, subject to that third party’s own privacy and cookie policies. We are not responsible for their practices. If we embed content (such as videos), the provider may process technical data (e.g., IP and browser identifiers) to deliver the content.

Data retention

• Newsletter: we keep your email until you unsubscribe (link in every email).
• Cookie preferences: stored locally for up to 1 year.

International data transfers

Some providers may process data outside your country. When this happens, we choose providers with appropriate privacy practices.

Children's privacy

This site is not directed to children under 13. We do not knowingly collect children's data. If you believe this happened, contact us for removal.

Security

We apply basic technical measures to protect your data, but no online method is 100% secure.

GDPR rights

• Access, correction, and updates to your data.
• Deletion, portability, and consent withdrawal.
• Objection or restriction of processing when applicable.

Use of content

The content is provided for informational purposes. You may reference it, but please do not redistribute as your own or use it in a misleading way.

Your choices

• You confirm your subscription by email before receiving content (double opt-in).
• You can unsubscribe from emails at any time via the link in our messages.
• You can request deletion of your contact data unless retention is legally required.
