# Data Enrichment and Privacy
 **Data Enrichment & Privacy Overview**\
At HockeyStack, we prioritize data privacy and compliance in all enrichment-related workflows. Below is an overview of how we approach privacy in our enrichment capabilities, especially as it relates to email and phone number enrichment.
\
 **Enrichment Providers**\
We license data from a variety of trusted third-party enrichment providers to maximize coverage and ensure high match accuracy across global markets. These providers specialize in B2B contact and company data.
* **Custom Provider Support:**
* If your organization has strict privacy policies or preferred vendors, we can integrate with your provider of choice to meet your internal compliance standards.
* **Provider Confidentiality:**
* Due to contractual obligations and intellectual property considerations, we do not publicly disclose the names of our enrichment providers. However, we fully own and operate our enrichment database, and our data contracts are structured to give us clear usage rights.
 **Privacy & Compliance Standards**\
Before onboarding any enrichment provider, we perform rigorous due diligence, including:
* GDPR compliance verification (including legal basis for processing B2B contact data)
* CCPA and other applicable privacy law assessments
* Security and data handling reviews
* Usage rights verification for downstream processing
We maintain internal policies for data minimization, access control, and user opt-out handling to further ensure compliance with international standards.
