1. Who We Are
0xNews is an AI-powered market intelligence service. For questions about this policy, contact us at support@0xnews.app.
2. Information We Collect
Information you provide
- Email address — collected if you submit the early-access form or enable email digests
- Google account name and avatar — collected when you sign in with Google OAuth
Information collected automatically
- Session data — a secure, HTTP-only cookie that identifies your logged-in session
- Usage data — signals you save to your portfolio, price alerts you set, and digest preferences. This data is stored in our database and associated with your account.
- Push notification subscription — if you opt in, your browser's push endpoint is stored to deliver alerts
- IP address — temporarily held in memory for rate limiting. Not persisted to disk or database.
3. How We Use Your Information
- To operate and provide the Service (account management, signal delivery, price alerts)
- To send email digests if you have opted in via Settings
- To send push notifications if you have subscribed
- To enforce rate limits and protect the Service from abuse
- To improve the Service based on aggregate, anonymized usage patterns
We do not sell, rent, or trade your personal information to third parties.
4. Third-Party Services
The Service relies on the following third parties:
- Google OAuth — used for authentication. Google's Privacy Policy applies to data shared during sign-in.
- Anthropic Claude API — article text (title and summary only) is sent to Anthropic for AI analysis. No personal information is included in these requests. Anthropic's Privacy Policy applies.
- Financial data providers — we fetch publicly available stock price data. No personal data is shared.
If payment processing is added in the future, this policy will be updated to reflect the payment processor's data handling.
5. Data Retention
- Account data — retained for as long as your account is active
- Portfolio and signal history — retained for as long as your account is active
- Email addresses from the early-access form — retained until you request removal
- Push subscriptions — retained until you unsubscribe or the subscription expires
6. Your Rights and Choices
- Email opt-out — disable email digests at any time in Settings
- Push opt-out — unsubscribe from push notifications at any time in Settings
- Data deletion — to delete your account and all associated data, email us at support@0xnews.app with the subject "Delete my account". We will process requests within 30 days.
- Access — to request a copy of the data we hold about you, contact us at the email above.
If you are located in the European Economic Area (EEA), you may also have rights under GDPR including the right to data portability, restriction of processing, and to lodge a complaint with your local supervisory authority.
7. Cookies
We use a single session cookie to keep you logged in. It is:
- HTTP-only (not accessible to JavaScript)
- SameSite=Lax (protects against cross-site request forgery)
- Secure (transmitted over HTTPS only in production)
We do not use advertising cookies, tracking pixels, or analytics services that track you across websites.
8. Security
We apply industry-standard security practices including HTTPS, HTTP security headers (Content Security Policy, HSTS, X-Frame-Options), input validation, and rate limiting. No method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.
9. Children's Privacy
The Service is not directed to children under 18. We do not knowingly collect personal information from children. If you believe we have inadvertently collected such information, contact us and we will delete it promptly.
10. Changes to This Policy
We may update this Privacy Policy from time to time. The "last updated" date at the top of this page indicates when changes were last made. Continued use of the Service after changes constitutes acceptance of the revised policy.
