What we hold

If you subscribe: your name and email address, your Stripe customer identifier, your plan and its status, your account id, a salted hash of your password, and your book (holdings, cash, notes, thesis text, calls and marks), stored under your account so it follows you between devices. We do not read your book. If you asked for a demo before 30 September 2026, when the form closed: your email and what you wrote. If you answer the questions after checkout (all optional): what you do, what you invest in, a rough range of how much, what it is for and how you found us, kept with your billing record and never with your book, and counted rather than read one by one. That is the list. We ask your age before checkout and keep only that you are 18 or older, never the number.

What we do not hold

Your card details, which Stripe holds. Your password as typed: we keep only a salted, slow hash of it (PBKDF2), which cannot be turned back into the password. With the record's server copy on (your choice) we hold your calls, marks and chain heads under your account, so the record can be attested and survives a lost device. This site uses Cloudflare Web Analytics, which counts page views without cookies and without identifying you; no advertising pixels, no third-party cookies. Nothing records your session: no screen recording, no keystroke or mouse capture, no replay tool of any kind. Fonts are served from this site, so loading a page sends nothing to Google or any other font host.

Cookies

One: the session cookie that opens the terminal once you have signed in. It is set only after you sign in, is not readable by scripts, and is not shared with anyone.

Who else sees anything

Stripe, for payment. Resend, to send account emails and replies. Cloudflare, which serves the site and runs the access service. Finnhub, when you connect your own key, under your own account with them. Groq, which answers the questions you put to the terminal's assistant: only when you ask, your question goes with a summary of your holdings (tickers, shares, values and the terminal's verdicts, never your notes), and we keep neither the question nor the answer. We do not sell or share your details with anyone else.

Your rights

Ask and we will show you what we hold, correct it, or delete it. Deleting your account ends your subscription and removes your email, code, sync data and the record's server copy; your export is yours to keep. Email northbridgeai1@gmail.com.

Retention

Subscriber records for as long as you subscribe and for the period the law requires for payment records afterwards. Demo requests from before the form closed, for twelve months.
