Newsletter Privacy Policy

Last updated: September 26, 2026

This policy explains what data ShamanTech collects when you subscribe to the newsletter at shamantech.dev, why it is collected, and what you can do about it. It is written to comply with Brazil's LGPD (Lei nº 13.709/2018) and the EU GDPR.

Who is responsible

ShamanTech is run by an independent creator based in Brazil, who is the data controller. For any privacy question or request, write to newsletter@shamantech.dev.

What we collect

• Email address (required) to send you the newsletter.
• Name (optional) to personalize emails.
• Topics of interest (optional), such as networking, distributed systems, infrastructure and blockchain, so you get content that matters to you.
• Engagement data: whether an email was opened, which links were clicked, and the approximate location and device inferred from that activity. This is collected through standard email tracking pixels and tracked links.
• Subscription records: signup date, source page and confirmation of consent.

How we use it

• Sending the newsletter and occasional announcements about new content, courses or products.
• Segmenting emails by the topics you chose.
• Measuring what works (open rates, clicks, A/B tests of subject lines and content) to improve the newsletter.

We never sell, rent or trade your data.

Legal basis

We process your data based on your consent, given when you subscribe and confirm your email (double opt-in). You can withdraw consent at any time.

Service providers

Your data is processed by a small number of trusted providers acting on our behalf:

• SendPulse: stores the subscriber list and sends emails.
• Google Analytics: measures website traffic, including visits coming from the newsletter.
• Vercel: hosts the website.

These providers may store data on servers outside Brazil or the EU. Transfers rely on the safeguards each provider offers, such as standard contractual clauses.

How long we keep it

We keep your data while you are subscribed. When you unsubscribe, your email is kept only on a suppression list so you are not emailed again, and all other data is deleted.

Your rights

You can, at any time:

• unsubscribe using the link at the bottom of every email;
• ask what data we hold about you and get a copy;
• correct inaccurate data;
• ask us to delete your data;
• withdraw consent or object to processing.

Send requests to newsletter@shamantech.dev. We reply within 15 days. You also have the right to lodge a complaint with a data protection authority, such as Brazil's ANPD or the authority in your EU country.

Changes to this policy

If this policy changes in a meaningful way, we will update the date above and notify subscribers by email.
