Information We Collect
1.1 Account Information
When you register, we collect your email address, username, and password. Passwords are never stored in plaintext; they are hashed with a unique per-user salt using a strong cryptographic algorithm.
1.2 Email Addresses Submitted for Verification
When you use the Service, you submit email addresses for verification. These are processed through our 5-stage pipeline and verification results are stored in your account's validation history.
1.3 Usage Data
We collect information about how you use the Service, including API call history, validation counts, credit transactions, login timestamps, and feature usage patterns.
1.4 Payment Data
Payments are processed by our third-party payment providers: Stripe (credit/debit card payments) and Cryptomus (cryptocurrency payments). We do not store your full card numbers, wallet addresses, or other sensitive payment details on our servers. We receive only transaction confirmations, reference IDs, and the minimum billing information required for accounting purposes.
1.5 Technical Data
We collect IP addresses, browser type, operating system, and login history for security and fraud prevention purposes.
