Privacy Policy

1. Who We Are

Kapitol.ai is operated by Knapen Shops, a Dutch sole proprietorship (eenmanszaak) based in the Netherlands. We provide a subscription service that tracks and analyzes publicly disclosed stock trades made by members of the United States Congress, and a developer API that offers programmatic access to that trade data.

For privacy inquiries, contact us at: hello@kapitol.ai

2. What Data We Collect

• Account data: your name and email address when you register
• Payment data: processed by Stripe (we do not store your card details)
• Newsletter data: your email address if you subscribe to our newsletter (The Kapitol Brief), managed by our newsletter provider Beehiiv
• API data: if you register for the Kapitol API, your account and contact details and your API usage records
• Usage data: pages visited and steps completed in the signup and trial flow, collected via Google Analytics and PostHog only after you consent
• Communications: messages you send us through in-app messaging or the contact form
• Email preferences: your notification settings

3. How We Use Your Data

• To provide and maintain your subscription or API account
• To send trade alert emails (if opted in)
• To deliver our newsletter (if subscribed)
• To send platform announcements (if opted in)
• To meter API usage against your plan and prevent abuse
• To respond to support requests
• To improve the platform through analytics

4. Legal Basis (GDPR)

• Contract performance: processing your account, subscription, or API plan
• Legitimate interest: improving our service and preventing abuse
• Consent: non-essential analytics, marketing, and newsletter emails. You can withdraw analytics consent through Cookie settings and email consent through your settings or the unsubscribe link.

5. Third Parties

• Stripe: payment processing and subscription and API billing
• Resend: transactional email delivery
• Beehiiv: newsletter delivery
• Google Analytics: website usage analytics after consent
• PostHog Cloud EU: product funnel analytics after consent, hosted in the European Union. Signed-in activity uses an internal account identifier rather than your email address.
• Finnhub and Yahoo Finance: stock price data
• TradingView: embedded price charts shown on stock pages

Congressional trade data is collected by us directly from the public U.S. House and Senate disclosure systems, supplemented by a historical dataset of public disclosures covering 2012 to 2025.

We do not sell your data to third parties.

6. Data Retention

We retain your account data for as long as your account is active. After account deletion, we retain minimal records for up to 90 days for legal and accounting purposes, then permanently delete them.

7. Your Rights (GDPR)

As an EU resident, you have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Request deletion of your data
• Object to or restrict processing
• Data portability
• Withdraw consent at any time

To exercise any of these rights, email us at hello@kapitol.ai. We will respond within 30 days.

8. Cookies

Essential cookies for session management and authentication are always active and do not require consent. Google Analytics, PostHog product analytics, and the embedded TradingView price charts are non-essential and load only after you accept them through our cookie banner. PostHog Session Replay is not enabled. You can withdraw your choice at any time using the "Cookie settings" link in the footer, or by disabling cookies in your browser settings.

9. Changes to This Policy

We may update this policy from time to time. We will notify registered users of material changes via email. Continued use of the service after changes constitutes acceptance of the updated policy.
