User Counting

eyeo's Browser Ad-Filtering Solution collects user data to understand cross-platform usage and versioning while maintaining strict privacy standards by excluding personally identifiable information.

Why eyeo Counts Users

eyeo tracks users with ad-filtering enabled and those with both ad-filtering and Acceptable Ads enabled for several purposes:

Version Management: Distribution data helps determine which product versions warrant ongoing support versus deprecation
Platform Prioritization: OS and platform analytics guide quality assurance and automation resource allocation
User Experience: Opt-out rates inform understanding of user perception regarding Acceptable Ads
Partner Compensation: Data establishes the foundation for partner payouts based on Acceptable Ads monetization

How User Counting Works

The Solution automatically sends ping requests to eyeo's service at minimum twice daily when the browser is active and ad-filtering is enabled. These requests contain no personally identifiable information.

Ping Request Payload

The system combines ping timestamps with randomly-generated tags and truncates dates for enhanced privacy protection.
