Privacy notice
How this service uses information you provide and the public business data it processes.
Account and service information
ProspectDrain stores account and order details, password hashes, service requests, extraction history and files to provide the service. Support and enterprise inquiries store your name, reply address and message for review by the site owner. Do not submit passwords, API keys or card details in support messages.
Contact research
Domain extraction processes available public business contact information. Results can be incomplete or outdated. Users should review relevance, accuracy and their basis for using contact information before outreach.
Google and Microsoft sign-in
If you choose provider sign-in, we use your provider identifier, name and email to create or connect your workspace. We request basic identity permissions only, not mailbox or calendar access. Provider access and refresh tokens are not stored. Existing accounts must be connected from an authenticated session.
Payments and email
Card checkout and subscriptions use Stripe. PayPal checkout provides prepaid access; PayPal processes your payment and returns transaction identifiers and payment status. The website stores these references to verify payment and manage access. We do not store card details. Email outreach uses the provider you connect and its rules and limits. Provider API credentials are encrypted on the server. Password recovery emails use a transactional provider when configured. Hosting, payment and email providers process information needed to operate their services.
Customer chat
When AI replies are enabled, they are the default customer chat mode. Your question and up to four earlier questions are sent to Z.ai for processing. You can switch to guided help instead; guided help stays on this page. The website does not save chat transcripts; this page’s chat history clears when you reload or use Clear chat. Z.ai’s processing and retention follow its API privacy terms. Do not enter passwords, API keys, payment details or sensitive personal information in chat. The assistant does not access private account records or submit support requests.
To limit abuse, AI chat keeps counters using a hashed visitor address. These expire within 24 hours and are cleared on subsequent AI requests. No raw address or chat text is stored in these counters. Z.ai privacy information ↗
Cookies and analytics
Essential cookies support sign-in and preferences. Optional analytics records daily page totals after consent. See the cookie notice for details and controls.
Storage and requests
Account records, extraction files and support requests are retained for service and operational needs; there is no automatic deletion schedule for these records. Optional analytics uses a rolling 90-day window. To request access, correction, deletion or information about processing, contact the site owner through support. Requests may require identity verification.
