Privacy Policy

Effective October 19, 2026

Stock Analyzer is run by Antrun ("we", "us"). This policy explains what information Stock Analyzer at stock-analyzer.antrun.com collects, how it's used, and the choices you have.

What we collect

• Your email address, which is your account. If you sign in with Google, we also receive your name and Google's account ID for you. We don't receive your Google password, contacts, or anything else from your Google account.
• What you add to the app: your watchlist, the trades and dividends you log or import (with any notes you write), and your trial or subscription status.
• Basic usage: which tickers you look up and on which days, the time you last used the app, and the AI reads and calls you generate. We use this to run features like the AI usage limit and to understand how the product is used.
• Sign-in requests: when you ask for an email sign-in link, we record the email, the time, and the requesting IP address, to limit abuse of the sign-in form.

How we use it

• To run the app: show your guardrails, journal, and Buy/Sell Analysis, and keep you signed in.
• To send you sign-in links, a welcome email when you join, and occasional product updates. You can opt out of product updates any time by replying "stop".
• To manage your trial and subscription.

Your trade data stays yours. It is never pooled with other users' data, never used to generate signals or evaluations for anyone else, and not used for any other purpose. We don't sell or rent your personal information.

Services we rely on

These providers handle data on our behalf, only as needed to run Stock Analyzer:

• Render hosts the app, and Neon hosts its database.
• Resend delivers our emails.
• Stripe processes payments. Your card details go to Stripe and never reach our servers; we keep only your Stripe customer and subscription IDs.
• Cloudflare protects the sign-in form (Turnstile) and provides privacy-friendly, cookie-free page-view statistics (Web Analytics).
• Google handles "Continue with Google" sign-in, if you choose it.
• OpenAI generates the AI reads and calls. We send it market data for the ticker (prices, indicators, analyst targets, public SEC filings) -- not your trades, email, or other personal information.

Market data comes from public sources such as Yahoo Finance and the SEC; looking up a ticker doesn't send them anything about you.

Cookies

We use one cookie to keep you signed in (for up to 30 days), plus a short-lived one during Google sign-in. We don't use advertising or tracking cookies.

Keeping and deleting your data

Your data is kept while your account is active. If your trial ends or your subscription is canceled, your account is deactivated, and its trades, dividends, and watchlist are permanently deleted 90 days later unless you reactivate. To delete your account sooner, or to get a copy of your data, write to support@antrun.com.

Security

Connections to Stock Analyzer are encrypted (HTTPS), there are no passwords to steal, and sign-in links work once and expire quickly. No system is perfectly secure, but we work to protect your information.

Children

Stock Analyzer isn't intended for anyone under 18, and we don't knowingly collect information from children.

Changes

If we change this policy, we'll update the date above. For a significant change, we'll also let you know by email.
