Privacy · Last updated November 2026
Your data, in plain language.
Short version: an email to sign in, what you create to be useful, and nothing sold to anyone.
What we store
An account is an email address and a password hash. Nothing else is required to use the terminal.
If you write something in the app — a watchlist, a chart setup, a paper position, an alert — it is stored against your account so it follows you to another device.
If you join a waitlist, we keep the address you typed so we can write to it once.
What we do not store
We do not ask for a phone number, a national ID or a broker credential, and we never ask for card details: there is no paid plan on sale yet.
We do not sell, rent or share personal data with advertisers. There is no ad network on this site.
Cookies and local storage
One cookie keeps you signed in. The browser also stores your language, market and chart preferences locally, which is why they survive a reload without an account.
The service worker keeps the shell of the app so it opens quickly; it does not read your data.
Push notifications
If you enable price alerts, the browser gives us a push endpoint and two keys. They are stored against your account and used only to deliver the alert you created.
Disabling notifications in the browser, or deleting the subscription from the alert centre, removes them.
Third parties
Market data: Finnhub (US stocks, crypto) and Yahoo Finance (Tadawul). Their responses are cached on our server; the request is not tied to you.
Charts: TradingView embeds. Their script runs on pages that show a chart.
Hosting and database: Vercel and MongoDB Atlas, which process requests on our behalf.
Your rights
You can delete your account from the profile page, which removes the watchlists, setups, positions and alerts attached to it.
For anything the app does not delete itself — a waitlist entry, for example — write to the address below and it is removed.
Questions, or a deletion request: use the repository's issue tracker or the contact shown on the about page. See also the terms of service.
Market data notice: quotes shown here may be delayed (Tadawul is about 15 minutes behind the exchange). Nothing on this site is investment advice.
