## Data

- Countries: United States, Puerto Rico, Guam, U.S. Virgin Islands, American Samoa, Northern Mariana Islands
- Keep data: no limit
- Use data: You agree not to: Use the Service for spam, harassment, fraud, or any unlawful purpose. Contact leads in violation of applicable laws (including anti-spam, telemarketing, and data-protection laws such as CAN-SPAM, the TCPA, and the GDPR where they apply). You are solely responsible for your outreach. Use the data to unlawfully discriminate against any individual or business. Sell, license, or redistribute data obtained from the Service, or access to the Service, or use either to build, populate, or supplement a database, lead product, or data service that competes with LeadMarina, whether or not you add anything to the data, without our prior written consent. Using the data within your own business (your employees and contractors included) is fine, and so is providing leads to your own clients for their own outreach as part of work you do for them — not as lists or data sold as a product, and not for resale — [...] Circumvent rate limits, quotas, or other technical restrictions. Scrape, reverse-engineer, disrupt, or attempt to gain unauthorized access to the Service.
