Privacy Policy

Last updated: March 24, 2026 — Effective date: March 24, 2026

This Privacy Policy describes how StockSync AI ("we," "us," or "our"), operated at stocksync-ai.com, collects, uses, and shares information when you visit or use our website. By using StockSync AI, you agree to the practices described in this policy.

1. Information We Collect

1.1 Information you provide

When you use our stock discovery tool, you may enter keywords, themes, or investment topics. This information is transmitted to our AI provider (Google Gemini) solely to generate stock ideas. We do not store this content on our servers after your session ends.

1.2 Usage data collected automatically

When you visit our site, we automatically collect certain technical information, including:

• Your IP address (anonymized)
• Browser type and version
• Pages visited and time spent
• Referring URL
• Device type and operating system

This data is collected via Google Analytics in aggregated, anonymized form to understand how visitors use our site.

1.3 Cookies and local storage

We use browser local storage to remember your daily usage count and Pro subscription status on your device. This data stays on your device and is not transmitted to our servers. Google AdSense and Google Analytics set their own cookies. You can opt out of Google's advertising cookies at adssettings.google.com.

1.4 Payment information

If you upgrade to Pro, payment is processed entirely by Stripe. We never see, store, or have access to your card details. Stripe's privacy policy is available at stripe.com/privacy.

2. How We Use Your Information

We use the information we collect to:

• Generate stock discovery results in response to your keyword searches
• Display relevant advertisements via Google AdSense
• Analyze site usage and improve our service
• Detect and prevent abuse or fraud
• Comply with our legal obligations

We do not use your search keywords for advertising targeting, and we do not sell, rent, or share your personal data with third parties for their marketing purposes.

3. Third-Party Services

• Google Gemini (AI provider) — processes your keyword prompts to generate stock ideas. See Google's Privacy Policy.
• Google AdSense — serves advertisements. See Google's Privacy Policy.
• Google Analytics — measures site traffic. See Google's Privacy Policy.
• Stripe — processes Pro subscription payments. See Stripe's Privacy Policy.
• Vercel — hosts our website. See Vercel's Privacy Policy.
• Yahoo Finance — we link to Yahoo Finance for live stock data. We do not share your data with Yahoo Finance.

4. Your Rights Under GDPR (EU / EEA Users)

If you are located in the European Union or European Economic Area, you have the following rights under GDPR:

• Right of access — request a copy of the personal data we hold about you
• Right to rectification — request correction of inaccurate data
• Right to erasure — request deletion of your personal data
• Right to restrict processing — request that we limit how we use your data
• Right to data portability — request your data in a portable format
• Right to object — object to processing based on our legitimate interests
• Right to withdraw consent — withdraw consent at any time where processing is consent-based

Our legal basis for processing is legitimate interest (operating and improving the service) and consent (advertising cookies). Since we do not require an account and do not store keyword content, the personal data we hold about any individual is minimal. To exercise your rights, you may lodge a complaint with your local data protection authority (e.g. CNIL in France, ICO in the UK).

5. Your Rights Under CCPA (California Users)

If you are a California resident, the CCPA provides you the right to know what personal information we collect, the right to delete it, and the right to opt out of its sale. We do not sell personal information. You do not need to opt out.

6. Data Retention

We do not store the keywords you enter. Usage counts stored in your browser's local storage are automatically cleared after 24 hours. Analytics data is retained by Google for up to 26 months in anonymized form.

7. Data Security

We use HTTPS encryption for all data transmitted to and from our site. We implement reasonable technical and organizational measures to protect your data. No internet transmission is 100% secure.

8. Children's Privacy

StockSync AI is not directed to children under 13 (or 16 in the EU). We do not knowingly collect personal information from children.

9. International Data Transfers

Our service is hosted in the United States via Vercel. If you access our service from the EU or other regions, your data may be transferred to and processed in the US. We rely on Standard Contractual Clauses where required by applicable law.

10. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated policy on this page with a new "Last updated" date. Continued use of StockSync AI after changes constitutes acceptance of the updated policy.

11. Important Notice

StockSync AI is an educational and research tool only. Nothing on this site constitutes financial advice. The AI-generated stock ideas are for informational purposes only. Always consult a licensed financial advisor before making investment decisions.
