Last updated: November 18, 2025

These Terms of Service (“Terms”) govern your access to and use of the LeadWinnow website located at https://www.leadwinnow.com (the “Site”) and the LeadWinnow browser extension (collectively, the “Service”). The Service is operated by Harper AI, Inc. (“Harper AI,” “we,” “us,” or “our”).

By accessing or using the Service, you agree to be bound by these Terms. If you do not agree to these Terms, you must not use the Service.

1. Eligibility and Agreement

1.1 Eligibility. You may use the Service only if:

• You are at least 18 years old, and
• You have reached the age of majority in your jurisdiction.

1.2 Authority. If you use the Service on behalf of another person or entity, you represent and warrant that you have authority to bind that person or entity to these Terms, and “you” will refer to that person or entity.

1.3 Acceptance of Terms. By installing the LeadWinnow extension, creating an account on the Site, or otherwise accessing or using the Service, you agree to these Terms and our Privacy Policy located at https://www.leadwinnow.com/privacy, which is incorporated by reference.

2. Description of the Service

2.1 Service Overview. LeadWinnow is a tool that helps users refine and organize lead and account data from LinkedIn Sales Navigator by:

• Applying filters (e.g., connection status, profile photo presence, premium/non-premium status, industry/company matching, and similar criteria) to lead/account data that is visible to you; and
• Providing AI-powered refinement features that process your collected lead/account data and your prompts to produce more targeted lead/account suggestions, rankings, or groupings; and
• Facilitating saving of leads/accounts to lists in LinkedIn Sales Navigator (initiated by you, where applicable).

2.2 Chrome Extension and Web App. The Service includes:

• A Chrome browser extension that operates when you view and interact with LinkedIn Sales Navigator pages; and
• A web-based interface at https://www.leadwinnow.com that may provide account management, settings, usage information, AI refinement features, and other functionality.

2.3 No LinkedIn Affiliation. LeadWinnow is not affiliated with, sponsored by, endorsed by, or in any way officially connected with LinkedIn Corporation or Microsoft Corporation. “LinkedIn” and “Sales Navigator” are trademarks of their respective owners. You are solely responsible for compliance with any third-party terms (including LinkedIn’s terms) that apply to your use of those services.

3. Relationship with LinkedIn and Third-Party Services

3.1 Independent Service. The Service interacts with web pages you visit, including LinkedIn Sales Navigator, by reading information that is available to you through your browser. Under the hood, the Service may interact with the same network requests that the page itself makes (such as pagination or result-loading requests) to surface and process lead/account data that is or would be visible to you as you use LinkedIn Sales Navigator.

3.2 No Automated Posting or Messaging. The Service does not send messages, connection requests, or other outbound communications from your LinkedIn account automatically. It is designed to help you filter, refine, and organize data that is already accessible to you on LinkedIn Sales Navigator.

3.3 User Responsibility for Third-Party Terms. You are solely responsible for:

• Understanding and complying with LinkedIn’s and any other third party’s terms, policies, and rules; and
• Any consequences (including limitations, suspensions, or termination of your LinkedIn account) that result from how you use the Service in conjunction with third-party services.

3.4 No Guarantee Against Account Restrictions. We do not control LinkedIn’s systems or enforcement decisions. We do not guarantee that use of the Service will be permitted by LinkedIn or that your LinkedIn account will not be restricted, limited, or terminated. You use the Service with LinkedIn at your own risk.

4. Account Registration and Security

4.1 Account Creation. To use certain features of the Service, you must create an account. When you register, you agree to provide accurate, current, and complete information and to keep that information up to date.

4.2 Authentication Provider. We use third-party authentication providers (such as Auth0) to manage sign-up and login. By using our Service, you also agree to be bound by any applicable terms of such authentication providers as they relate to your account authentication.

4.3 Account Credentials. You are responsible for maintaining the confidentiality of your login credentials and for all activities that occur under your account. You must immediately notify us at support@leadwinnow.com if you believe your account has been compromised.

4.4 Account Sharing. We do not require that accounts be non-shared, but you remain fully responsible for any use of your account, whether or not authorized by you.

5. Free Tier, Credits, and Payments

5.1 Freemium Model. The Service may offer:

• A free tier with limited features and/or usage; and
• Paid features and usage based on credits (“Credits”).

We may change what is included in the free tier or paid features at any time as described in Section 14 (Changes to the Service and Terms).

5.2 Credits. Credits are a digital usage unit that may be required for certain actions or AI-powered features within the Service. When you use a Credit-based feature, Credits are deducted from your account according to the then-current rates displayed in the Service.

5.3 One-Time Credit Purchases. Credits are currently sold as one-time purchases. Credits do not automatically renew. You may purchase additional Credits when your balance is low or depleted.

5.4 Credit Expiration. Purchased Credits expire one (1) year from the date of purchase if unused. Expired Credits will not be refunded or reissued. We may, but are not obligated to, provide reminders regarding upcoming expiration.

5.5 Payments and Taxes. Payments for Credits and any other paid features are processed by third-party payment processors (such as Stripe). By making a purchase, you:

• Authorize us and our payment processor to charge your selected payment method for the applicable amounts; and
• Agree to pay all fees and applicable taxes (such as sales tax, VAT, GST) that may be imposed by law and calculated by the payment processor or us at the time of payment.

5.6 Pricing. Prices for Credits and other paid features are as displayed in the Service at the time of purchase. We may change pricing at any time in accordance with Section 14.

5.7 No Refunds. All purchases are final and non-refundable, except where required by applicable law. We are under no obligation to provide refunds or credits, including for unused or expired Credits, partial periods of usage, or for accounts that are terminated or suspended, regardless of the reason.

6. License to Use the Service
