Privacy Policy

What we collect

• Account data. Email, name, and Google OAuth ID from your sign-in.
• Usage data. Which pages you visit, which AI queries you run, credits consumed, features accessed. We use this to compute your plan usage and to fix product bugs.
• Content you create. Watchlists, portfolios, saved strategies, chat history — all stored so you can return to it.
• Payment data. Handled entirely by Stripe. We never see or store your card number.

What we don't collect

• Your brokerage credentials. We are not connected to any broker.
• Your trades, unless you manually enter them into the Portfolio feature.
• Anything from your browser other than what's needed to render the app.

How we use it

• To operate the Service — render pages, run AI calls, track usage against your plan.
• To improve the product — anonymized aggregate metrics on which features are used.
• To communicate with you — service emails only (billing, security). We do not send marketing emails without opt-in.

Third parties

• Stripe — payment processing.
• Google — OAuth sign-in.
• Anthropic — LLM inference. Your queries are sent to Anthropic's API; per their policy, they do not train on API traffic by default.
• Polygon, S&P, Yahoo, SEC — market data providers. We fetch data from them; we do not send your personal data to them.
• Google Analytics — usage analytics.

Data retention

Your account data, watchlists, portfolios, and chat history are retained while your account is active. Delete your account from the Account page to remove them; some backups may persist for up to 90 days.

Your rights

You can request an export of your data or deletion of your account at any time by emailing support@erina.ai. If you are in the EU, UK, or California, additional rights apply under GDPR / CCPA — we honor them regardless of jurisdiction.

Security

Data is encrypted in transit (TLS 1.2+) and at rest (Cloud SQL, ClickHouse cluster). Access to production is IAM-restricted. Report security issues to security@erina.ai.

Changes

We may update this policy; material changes will be notified via the Service or by email.
