Privacy
Last updated 17 October 2026.
The short version
We collect what the product needs to work and nothing for advertising. We do not sell your data, we do not share it with ad networks, and there are no third-party trackers on this website. Your options paper book is yours.
What we collect
If you have an account
- Email address — to identify you and to reply to you.
- A password hash — never the password itself. It is hashed with a slow, salted algorithm.
- Your options paper book — the day’s paper money you commit, the paper contracts bought and sold with it and the ledger entries that record them. No real money is involved.
If you connect a broker
- An access token, encrypted at rest with authenticated encryption. It expires daily by the broker’s own rule.
- Your broker user id, as the broker returns it, so the connection can be shown as active.
We never see your broker password. You authenticate with the broker directly on their own login page. We never display the access token back to a browser.
If you write to us
- Your name, email address and your message — used to reply, and kept while the conversation is useful.
From this website
This site sets no cookies and loads no third-party scripts, fonts or analytics. Our hosting provider keeps standard server logs — IP address, timestamp, page requested, user agent — for security and troubleshooting. We do not build profiles from them.
What we do not do
- We do not sell or rent personal data to anyone.
- We do not share it with advertising or data-broker networks.
- We do not use advertising or cross-site tracking technology.
- We do not read, trade on, or share your options paper book.
- We do not have access to your money or the ability to move it.
Market data is not personal data
Prices, volumes, option chains and the instrument list are public market facts. They are stored once and shared across accounts — the price of a stock is not personal to you. What is personal is the fact that you follow a particular stock, and that stays private to your account.
Who else is involved
| Who | What for | What they get |
|---|---|---|
| Our market data provider and your broker | Market data, and your broker connection if you make one | What their own login and API require. Governed by their own privacy policies. |
| Our hosting providers | Running the servers and serving this site | Server logs, and the data at rest on the instances they host |
How long we keep things
- Account data — while your account exists.
- Broker tokens — until they expire, which is daily, or until you disconnect.
- Market data — daily bars indefinitely, intraday bars and option chains for a bounded window, then deleted.
- Emails to us — while the conversation is useful.
Your rights
You can ask us to show you what we hold about you, correct it, export it, or delete it and your account. Write to admin@billixindia.com and we will act within a reasonable period.
Deleting your account removes your email, your options paper book and any stored broker token. It does not remove market data, which is not yours or ours but the market’s.
Security
Passwords are hashed, broker tokens are encrypted at rest with authenticated encryption — a tampered record fails to decrypt rather than decrypting to something wrong — and traffic to this site and the application is over TLS. No system is perfectly secure, and we will tell you promptly if something happens that affects you.
Children
Stockhub is not intended for anyone under 18 and we do not knowingly collect their data.
Grievances
For a privacy complaint, write to admin@billixindia.com with privacy in the subject. We will acknowledge it and tell you what we are doing about it.
Changes
If this policy changes materially we will say so on this page and date it. The date at the top is when it last changed.
