Privacy Policy

Last updated: January 2026

1. Introduction

Market Signal ("we", "us", "our") provides an AI-powered market-research platform that analyzes publicly available online discussions and search-trend data to help users validate market needs (the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you access or use the Service.

Your use of the Service is also governed by our Terms of Service.

2. Information We Collect

Public & Search Data

• Publicly available posts, comments, and metadata retrieved via the Reddit API.
• Search interest and volume data retrieved via the DataForSEO API.

Account & Service

• Email address, password, and session identifiers.
• Queries submitted, analysis records, and related metadata needed to provide the Service.

Usage & Device Data

• Log files, IP address, browser type, device identifiers, and similar signals collected to operate and secure the Service.

Payments

• Subscription and billing details handled by our payment processor. We never store full card numbers.

Cookies & Similar Technologies

• Small data files stored on your device to keep you signed in and measure Service performance.

3. How We Use Your Information

• Provide, maintain, and improve the Service, including support, security, and troubleshooting.
• Retrieve publicly available data for analysis using third-party APIs (including Reddit and DataForSEO).
• Process queries to generate insights with third-party AI providers (including Anthropic and OpenAI).
• Process payments and manage accounts and subscriptions through Stripe.
• Comply with legal obligations.

4. Legal Bases (EU/EEA)

We process personal data only when we have a lawful basis: (i) to fulfill a contract (provide the Service), (ii) with your consent (optional communications), (iii) to pursue our legitimate interests (improving and securing the Service), or (iv) to comply with legal obligations.

5. How We Share Information

We do not sell your personal data. We share it only with:

• Service providers who perform services for us (payment processing, AI analysis, and search data providers) under confidentiality agreements.
• Authorities or other parties when required by law or to protect rights, safety, or property.

6. Business Transfers

If we are involved in a merger, acquisition, financing, or sale of assets, your information may be transferred as part of that transaction, subject to this Privacy Policy.

7. International Transfers

If we transfer data outside the European Economic Area, we rely on appropriate safeguards such as Standard Contractual Clauses.

8. Data Retention

We retain personal data only as long as necessary for the purposes described above or as required by law. Search queries may be anonymized and aggregated for product-improvement analytics.

9. Data Deletion

You may request deletion of your account and associated personal data through the account manager (Stripe customer portal) or by contacting us directly. We will delete or anonymize personal data where possible, and may retain certain records as required by law or for legitimate business purposes (such as billing or security).

10. Children's Privacy

The Service is not intended for children under 13 (or the applicable age of consent in your jurisdiction). We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, please contact us so we can take appropriate action.

11. Your Rights

Subject to local law, you have the right to access, correct, delete, or port your personal data, and to object to or restrict processing. You may withdraw consent at any time. To exercise these rights, please contact us.

12. Security

We employ industry-standard technical and organizational measures to protect your data. No online service is 100% secure; you use the Service at your own risk.

13. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date indicates when changes were last made. Material changes will be notified via email or prominent notice on the Service.
