Privacy Policy

What we collect

Product analytics (PostHog). We use PostHog to record behavioral events: page views, page leaves, and interactions with features like the screener and charts. This tells us which parts of the site are useful and which are ignored. Analytics data is processed on PostHog's US cloud. We use it in aggregate for product decisions and do not sell it.

Hosting logs (Vercel). The site runs on Vercel, which keeps standard request logs: IP address, browser user agent, requested URLs, and timestamps. We use these to operate, debug, and secure the site.

Infrastructure (Supabase). Our databases run on Supabase. They store the valuation dataset and response caches, plus account IDs, email addresses, followed entities, alert settings, saved screens, subscription preferences and plan access. These records let us save your research and apply your notification choices.

Email. If you email us, we keep the correspondence. If you subscribe, we store your email address, subscription status, preferences and signup source. Resend processes email delivery. Confirmation links expire after 24 hours; confirmation and unsubscribe tokens are stored as hashes.

What we do not collect

The app does not collect passwords. Sign-in uses an emailed magic link, with Google sign-in available when enabled. We hold no brokerage connections, portfolio holdings or payment information. We do not buy data about visitors, and we do not sell or rent any data to anyone.

Cookies and local storage

• Sign-in cookies. Supabase uses cookies to keep your authenticated session active.
• Theme preference. Your light/dark choice is stored in your browser's local storage so the site remembers it. It never leaves your browser.
• One-time UI hints. Dismissed hints and tips are remembered in your browser so they stay dismissed.
• Analytics identifiers. PostHog stores an identifier in your browser to distinguish visits. It is used for analytics, not advertising.

There are no advertising cookies and no third-party ad trackers.

Data retention

We keep data on a best-effort, shortest-useful basis. Hosting logs and analytics events are retained per our providers' default retention windows; aggregate analytics may be kept longer for product decisions. If you want something about you removed, email us and we will make a good-faith effort.

Changing email preferences

You can inspect and change email preferences in your account, or use an email's unsubscribe link without signing in. Unsubscribing retains the subscription record so we can respect your choice. It does not delete your account or the entities you follow. For a deletion request, contact the team.

Your rights

Depending on where you live (for example, the EU/EEA and UK under GDPR, or California under CCPA/CPRA), you may have rights to access, correct, delete, or export personal data we hold about you, and to object to certain processing. To exercise any of these rights, contact the team.
