Who is the data controller
Dan Dezmirean, an individual based in the EU, is the controller of any personal data you submit on this site. You can reach him at dandezmirean@gmail.com.
What this site does not do
No analytics. No advertising trackers. No third-party cookies. No fingerprinting. The site loads its own assets and a single self-hosted audio file. No data is sent to any third party when you simply browse.
What happens if you subscribe to the newsletter
When you submit the subscribe form, the following data is processed:
- Email address — the one you typed.
- Timestamp — when you subscribed and when you confirmed.
- IP address — recorded once at subscribe time, used only for rate-limiting and abuse prevention (legitimate interest under GDPR Art. 6(1)(f)).
- Consent flag — a record that you ticked the consent checkbox.
Purpose: sending the Claude Mastery newsletter to people who explicitly asked for it.
Legal basis: your explicit consent (GDPR Art. 6(1)(a)). You confirm twice — once with the checkbox, once by clicking the confirmation link in the verification email (double opt-in).
Where the data is stored
Subscriber records are stored in a SQLite database on the hosting provider (Hostinger International Ltd, EU). Confirmation and newsletter emails are delivered via an SMTP relay configured by the controller. No subscriber data is shared with marketing networks, sold, or transferred outside the EU.
How long the data is kept
Until you unsubscribe, or 3 years after the last newsletter you opened — whichever comes first. After that, the record is deleted.
Your rights under GDPR
You have the right to:
- Access the data held about you (Art. 15).
- Rectify inaccurate data (Art. 16).
- Erase your data (Art. 17) — including the right to be forgotten.
- Port your data to another service (Art. 20).
- Withdraw consent at any time. The unsubscribe link at the bottom of every newsletter does this in one click. You can also email dandezmirean@gmail.com.
- Lodge a complaint with your national data protection authority if you believe your rights have been violated.
Automated decision-making
None. There is no profiling, no segmentation, no AI-driven targeting. Everyone on the list receives the same newsletter.
Cookies and local storage
This site sets no tracking cookies. It uses the browser's localStorage only for non-essential UI preferences (last-opened panel, reduced-motion handling). No personal data is stored there. You can clear it any time from your browser settings.
Changes to this notice
If the data handling materially changes, this notice is updated and the date at the top is bumped. Subscribers are notified by email if the changes affect them.
