This Privacy Policy describes how we collect, use, store, and protect information when you use our desktop application, web platform, API services, and website (collectively, the "Service"). By using our Service, you agree to the data practices described in this policy.
2. Information We Collect

4. Data Storage & Security
4.1 Data Storage
Your account data is stored on secure servers. License validation data (license key, machine ID, hardware fingerprint) is stored for the duration of your license period and deleted within 30 days of license expiration or account deletion.
4.2 Security Measures
We implement industry-standard security measures to protect your information:
- AES-256 encryption for sensitive data at rest
- TLS 1.3 encryption for all data in transit
- Hardware-bound license validation to prevent unauthorized use
- Anti-tampering mechanisms in the desktop application
- Regular security audits and vulnerability assessments
- Access controls limiting data access to authorized personnel only
4.3 Data Retention
We retain your account information for as long as your account is active or as needed to provide you the Service. Anonymized usage data may be retained indefinitely for analytics purposes. Upon account deletion, personal data is removed within 30 days.
5. Local Processing
A core design principle of Leads Sentry is local-first processing. This means:
- All email verification is performed on your local machine. Email addresses are never transmitted to our servers for verification.
- DNS lookups and SMTP connections are made directly from your machine to the target mail servers.
- Verification results, reports, and exported files remain on your local device.
- The desktop application can function in offline mode for previously downloaded datasets.
The only data transmitted to our servers is license validation information and anonymized usage analytics (which can be disabled in settings).
6. Third-Party Services
We may use the following third-party services:
- Payment Processing: To securely process license purchases. These processors handle your payment card data in compliance with PCI-DSS standards.
- Infrastructure Providers: Cloud hosting services for our license validation API and website.
- Analytics: Anonymized analytics tools to understand usage patterns and improve our product.
We do not sell, rent, or share your personal information with third parties for their own marketing purposes. Third-party service providers are bound by data protection agreements and are only permitted to process data as necessary to deliver their services to us.
