Privacy Policy

OneStockApp is an independent personal project, not a company. This describes plainly what happens with your data if you use it - it isn't a substitute for legal advice.

What's collected

Your account email and password (handled by Supabase Auth - passwords are never visible to or stored by this app directly), and whatever you enter yourself: trades, watchlists, journal notes, criteria tags, calculator inputs, and similar. There's no tracking or analytics beyond what's needed to keep you signed in (a session cookie).

Where it's stored

In a Postgres database hosted by Supabase. It isn't sold, shared, or used for advertising.

Third-party market data

Some pages look up public market data (prices, volatility, breadth) from Yahoo Finance and, if you've connected it, Schwab's Market Data API. Those lookups are by ticker symbol only - your account information, trades, or journal entries are never sent to them.

Data removal

This is a personal project without a dedicated support channel or a self-serve account deletion feature at this time. Keep that in mind before signing up with data you'd want reliably erasable on demand.

Changes

This page may change as the app changes. There's no notification system for updates - check back if you're curious.
