Privacy
The plain-language version first: this is an open project by design. People's names, birth details and reports you add are published for anyone to see — that is the point of the shared network. Enter another person's details only with their permission, and mark a report "private" if it should stay yours alone.
Who is responsible
This site is a private one-person project — made by someone who travels; its legal home is Italy. Contact: lucap@live.de
What is stored
Accounts: username, an optional display name, an optional email (only used for password resets and, if you opt in, the daily digest), and a securely hashed password.
People & charts: the name, birth date, time and place you enter, the positions computed from them, and any contact links you explicitly choose to publish. These are public unless created as private.
Reports: the generated text and PDF. Public unless you ticked "private report".
Usage statistics: we count page views with a short-lived anonymised visitor token — no advertising trackers, no third-party analytics, no profiling. The only cookie is the session cookie that keeps you signed in.
Where it lives
The site runs on Hugging Face Spaces; the database is backed up to a private Hugging Face dataset. Hugging Face may process technical data (such as IP addresses) as the hosting provider.
AI writing
To write a report, the computed chart data and first names are sent to the AI model chosen for that report — Anthropic, or another provider routed through OpenRouter. They are used only to write the text.
Password-reset links and the optional daily digest are sent through Resend, only to the address you gave us. No marketing, ever.
Location
The live-sky page uses a location only when you tap the 📍 button — an approximate, network-based lookup used once to set the map point. It is not stored.
Your rights
You can see, correct and delete your data: edit your own entry with your edit password, delete your account's entries yourself, or simply email us — we will remove your entry and reports. Deletion is real and carries through to the backup. You also have the right to complain to a data-protection authority — in Italy, the Garante per la Protezione dei Dati Personali.
One honest line
Thunder & Lightning is for self-reflection, curiosity and joy — it is not medical, psychological, legal or financial advice.
