1. Overview

Signal1st ("we", "us", "our") operates a service that monitors public discussions across social platforms and communities to identify buyer intent for your business. This Privacy Policy explains what information we collect, how we use it, and the choices you have. It applies to our website and the Service.

2. Information We Collect

We collect the following information:

  • Account information. When you sign up, we collect your business email address, your business website, and the plan you selected (Growth or Scale).
  • Website content. After you verify your email, we retrieve the public content of your website to build your company profile, including your competitors, relevant communities, and keywords.
  • Usage data. We collect basic, privacy-friendly analytics about how visitors use our website, such as page views, referrers, and device type.

3. How We Use Information

We use the information we collect to:

  • Create and manage your account and verify your email address.
  • Build and maintain your company profile and configure monitoring for your business.
  • Provide, operate, and improve the Service.
  • Communicate with you about your account and the Service.
  • Analyze and improve our website and marketing.

4. Analytics and Cookies

We use PostHog, hosted in the EU, to measure how visitors use our website and understand where they engage or drop off. PostHog processes page views, clicks, and similar usage signals, and sets a cookie to recognize your browser for analytics purposes. You can disable or delete analytics cookies in your browser settings. We do not sell your data or use third-party advertising cookies.

5. Data Sharing

We do not sell, rent, or trade your personal information. We share information only with service providers who help us operate the Service, such as hosting and infrastructure providers and the AI services used to analyze website content, and only to the extent necessary to provide the Service. These providers are required to protect your information.

6. Data Retention

We retain your account information for as long as your account is active or as needed to provide the Service. Pending signups that are not verified are retained until they are verified or removed. We may retain aggregated, anonymized data for analytical purposes. You may request deletion of your personal information at any time.

7. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, or delete the personal information we hold about you, to object to or restrict certain processing, and to receive a copy of your data in a portable format. To exercise any of these rights, contact us at hello@signal1st.io and we will respond within the timeframe required by law.

8. Security

We take reasonable technical and organizational measures to protect your information against unauthorized access, loss, or alteration. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

9. Children's Privacy

The Service is intended for businesses and is not directed to individuals under the age of 16. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us at hello@signal1st.io and we will delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Effective" date above and, where appropriate, notify you. Your continued use of the Service after changes take effect constitutes acceptance of the revised policy.
