Privacy Policy
How BullYeah handles your data.
Last updated September 2026.
What we collect
Account data: if you create a free account, we store your email address and authentication credentials with Supabase, our authentication provider. We never see or store your plaintext password.
Product data: watchlists, favorites, and saved history you create in the app, tied to your account (or, for anonymous use, to your browser session only).
Usage analytics: when configured, BullYeah uses PostHog to understand which pages and features are actually used — page views, session duration, and feature interactions. Anonymous visits are tracked as lightweight, non-identified events. This is off entirely in any environment where it isn't explicitly configured.
Cookies: a session cookie keeps you signed in. We don't use third-party advertising cookies.
What we don't do
We don't sell your personal data. We don't share your watchlist or account activity with third parties for advertising purposes.
Third-party services
BullYeah relies on third-party infrastructure to operate: Supabase (authentication and database hosting), and market/financial data providers described on the Data Sources & Coverage page. Each of those providers has its own privacy practices for data they process on our behalf.
Your choices
You can use most of BullYeah without an account. If you have an account, you can request deletion of your account and associated data at any time by emailing support@bullyeah.com.
Changes to this policy
As BullYeah adds features (billing, alerts, notifications), this policy will be updated to reflect what's actually true at the time, not in advance of it.
This page describes BullYeah's actual current data practices. It is not a substitute for legal advice, and has not yet been reviewed by outside counsel — that review is required before Pro billing goes live and any user is charged.
