Privacy notice

Pablo Azaretzky, Amsterdam, the Netherlands. You can reach me through the contact form on the home page.

Visits are counted with Vercel Web Analytics: page views, country, referrer and device type, in aggregate. It uses no cookies and does not identify you.

If you use the contact form, your name, email and message are sent to me by email so I can reply. They are not stored in a database.

Every tool works without an account. Signing in with Google is optional and only used to save your work.

If you sign in, I store your Google account email and the items you choose to save (for example a valuation with your assumptions, a bond or an option strategy), with the date. Nothing else: no password, no contacts, no browsing data.

Saved items are stored in a PostgreSQL database hosted by Neon in the EU (Frankfurt). The app runs on Streamlit Community Cloud. Market data comes from Yahoo Finance; your saved items are not shared with anyone.

The legal basis is your consent when you sign in and save (GDPR art. 6(1)(a)). Your data is kept until you delete it.

You can delete everything at any time: in the app, open “My saved work” → Account → “Delete everything”. You can also ask me for a copy, a correction or the deletion of your data through the contact form.

You may lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
