Privacy
This page describes what we store and which third parties may see data when you use AlphaSignal.
What we store
If you create an account we store your username, email, password hash (when you use a password), optional Google account link, optional MFA secret, My Top favorites (up to 5), and email/alert preferences. We do not sell personal information.
Browser storage
A sign-in token may be kept in your browser (localStorage) so you stay logged in. Guests may also keep a temporary My Top draft in localStorage until they sign in. You can sign out to clear the token.
Google Sign-In
If you choose Continue with Google, Google verifies your identity and we receive your Google user id, email, and display name to create or link your AlphaSignal account. We do not receive your Google password.
My Top daily email
New accounts get weekday My Top digest email by default (after the morning scan snapshot). You can turn it off in Account or via the unsubscribe link in every digest. Optional alert rules (score thresholds, rating changes) ride the same email when enabled. Digests are context only — not investment advice.
Market data providers
Scores, prices, filings, and headlines come from public or licensed sources (for example SEC, Yahoo Finance, FRED, Finnhub, FinanceDataReader, and OpenDART for Korean equities). Your browser may request those pages when you open an outbound link.
Advertising cookies
Third-party ad cookies are not loaded until a publisher id is configured. This site may still use essential cookies or local storage for sign-in.
Analytics
Google Analytics is not loaded until a measurement id is configured. Page-view analytics stay off by default.
