Privacy Policy

Lynx Signal ("we", "us", "our") operates the Lynx Signal Chrome extension and the web platform available at lynxsignal.com. This Privacy Policy explains how we collect, use and protect information when you use our products.

2.1 Chrome Extension

When you use the Lynx Signal Chrome extension, it may process the following data:

• LinkedIn post content — text of posts visible in your feed, used solely to detect buying signals. Post content is sent to our secure server for AI analysis and is not stored after processing.
• Author information — publicly visible name, job title, company and LinkedIn profile URL of post authors, used to populate your lead records.
• Saved leads and pipeline data — leads you choose to save, their pipeline stage (Saved, Contacted, Negotiation, Closed) and any notes. This data is stored locally in your browser and optionally synced to your Lynx Signal account.
• Extension settings — your preferences (language, minimum score threshold, signal filters) stored locally in your browser.

2.2 Web Platform (lynxsignal.com)

• Account information — your email address and password (hashed) when you create an account.
• Billing information — handled entirely by Stripe. We do not store your payment card details.
• Usage data — number of leads saved, credits consumed, campaigns sent. Used to manage your subscription plan limits.

• To provide, maintain and improve the signal detection features of the extension.
• To sync your leads and pipeline across devices when you are signed in.
• To manage your subscription, credits and billing via Stripe.
• To send transactional emails (account confirmation, billing receipts). We do not send marketing emails without your explicit consent.

We do not sell your data to third parties. We do not use your data for advertising purposes.

Lynx Signal uses AI to analyse LinkedIn post content and detect buying signals. All AI processing is performed server-side on our secure infrastructure (Cloudflare Workers). Post content is transmitted over HTTPS, analysed, and the result (signal type and score) is returned to your extension. Raw post text is not stored on our servers after analysis.

The extension never sends your LinkedIn credentials, cookies or session tokens to our servers or to any third party.

We share data only in the following limited circumstances:

• Stripe — for payment processing. Subject to Stripe's Privacy Policy.
• Cloudflare — our infrastructure provider for hosting and serverless compute. Subject to Cloudflare's Privacy Policy.
• Legal requirements — if required by law or to protect our rights.

We do not share, sell or transfer your data to any other third party.

• Lead and pipeline data is retained for as long as your account is active.
• You can delete individual leads at any time from the extension or dashboard.
• You can delete your entire account and all associated data by contacting us at [email protected]. We will process the request within 30 days.
• Local browser data (chrome.storage) is cleared when you uninstall the extension.

All data in transit is encrypted via HTTPS/TLS. Your account password is stored as a salted hash and never in plain text. We follow industry-standard security practices and perform regular security reviews.

If you are located in the European Economic Area, you have the right to:

• Access the personal data we hold about you.
• Rectify inaccurate data.
• Request deletion of your data ("right to be forgotten").
• Object to or restrict processing of your data.
• Receive your data in a portable format.

To exercise any of these rights, contact us at [email protected].

The Lynx Signal website uses a single session cookie to keep you signed in to your account. We do not use tracking cookies or third-party advertising cookies.

Lynx Signal is not directed at children under the age of 16. We do not knowingly collect personal data from children.

We may update this Privacy Policy from time to time. We will notify registered users by email of any material changes. The "Last updated" date at the top of this page always reflects the most recent revision.
