How to Opt Out and Remove Your Information from KnowThyCustomer
KnowThyCustomer provides a privacy policy linked on their website, and this presumably includes options for contact or data‑removal requests. However, like many data brokers, removal is often limited and inconvenient: requesting redaction does not guarantee full deletion across all systems or downstream clients. Individuals seeking privacy protection should expect the process to be partially manual and potentially time consuming.

KnowThyCustomer Privacy Risks and How to Remove Your Personal Data
Contact Enrichment from Partial Identifiers
KnowThyCustomer allows businesses to submit partial data (e.g. a phone number, email, or address) and uses its database to “fill in the blanks.” Through this enrichment process, they link partial identifiers to a complete profile — including contact details and social‑profile information — expanding CRM entries or lead lists for their clients
They engage in automatic data harvesting:
Although KnowThyCustomer does not publish detailed data‑source logs, the nature of their service — resolving phone numbers or emails to names and social profiles — implies that they aggregate data from public records, social media or online activity, and possibly other third‑party data providers or scraped sources. This aligns with common industry practices where brokers compile public and semi‑public data to build enriched identity profiles.
Opting out is possible, but removal is difficult:
Once aggregated and enriched, data is offered to businesses for a variety of purposes: marketing lead generation, CRM enhancement, candidate or customer vetting, fraud reduction, and compliance screening. This dual marketing and risk‑mitigation orientation increases the utility of the data — but also magnifies privacy risks for individuals whose data is included.
