Privacy Policy
Last updated: February 22, 2026
Introduction
Stock Prism ("we", "our", or "the Service") is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your choices regarding your data. By using Stock Prism, you agree to the collection and use of information as described in this policy.
1. Information We Collect
When you sign in to Stock Prism using Google OAuth, we receive your name, email address, and profile picture from your Google account. We also store your analysis history (tickers analyzed, scores, and analysis results), your investor profile preferences (risk tolerance, investment horizon, valuation parameters), and basic usage data (analysis count, timestamps). We do not collect financial account information, brokerage credentials, or any sensitive financial data beyond what is publicly available.
2. How We Use Your Information
We use the collected information to: (a) provide and maintain the Service, including personalized analysis history and preferences; (b) enforce usage limits and prevent abuse; (c) improve the Service by understanding usage patterns; (d) communicate with you about service updates if necessary. We do not sell, rent, or share your personal information with third parties for marketing purposes.
3. Data Storage and Security
Your data is stored securely using managed cloud infrastructure with enterprise-grade security. We implement strict access control policies to ensure that users can only access their own data. All data is transmitted over encrypted connections. While we take reasonable measures to protect your information, no method of electronic storage is 100% secure.
4. Cookies and Tracking
Stock Prism uses essential cookies for authentication session management. We use error tracking tools for application monitoring, which may collect anonymized technical data (browser type, error logs). If enabled, Google AdSense may use cookies to serve personalized ads based on your browsing history. You can manage cookie preferences through your browser settings.
5. Third-Party Services
Stock Prism integrates with the following third-party services: Google for authentication (OAuth) and advertising (AdSense), as well as cloud infrastructure providers for data storage and error monitoring. Each of these services has their own privacy policies, and we encourage you to review them. We only share the minimum data necessary for these services to function.
6. Data Retention
We retain your analysis history and account data for as long as your account is active. Analysis results are cached for up to 24 hours for performance. You may delete individual analyses or your entire account at any time. Upon account deletion, we will process your deletion request and permanently remove your personal data from our systems.
7. Your Rights
You have the right to: (a) access the personal data we hold about you; (b) request correction of inaccurate data; (c) request deletion of your account and associated data; (d) request a copy of your analysis history. To exercise any of these rights, please contact us through the Feedback page.
8. Children's Privacy
Stock Prism is not intended for use by individuals under the age of 18. We do not knowingly collect personal information from children. If we become aware that a child has provided us with personal information, we will take steps to delete that information.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
