Attribution quality without compromising compliance
Use first-party, opt-out, aggregate-only, access, and retention controls without sacrificing attribution quality.
First-party architecture. Data stays on your domain.
Kleerr's first-party pixel runs on your domain, keeping tracking data in your first-party infrastructure instead of a third-party pixel.
First-party pixel on your domain
Your pixel, your domain, your cookies. No third-party scripts that can be blocked or stripped.
First-party event capture
Conversion events captured via first-party infrastructure. No third-party dependencies.
First-party cookies only
No third-party cookies. No cross-site tracking. Fully compliant with browser privacy restrictions.
Choose the right privacy posture for your business
Opt-out (default)
Visitors can opt out of tracking. Standard for US and California compliance. Enabled by default on every plan.
Opt-in PII
When a user authenticates or consents, Kleerr enriches their profile with identifiable data. Full journey visibility for known users.
Aggregate-only
All journey stitching on hashed values. No individual PII stored or accessible. Maximum compliance posture for teams that need it.
Maximum compliance. Same signal quality.
For teams that need the strictest compliance posture, Kleerr can operate in aggregate mode. All journey stitching runs on hashed values. No individual PII stored or exposed.
Hashed identity stitching
Journey connections built on hashed values. Individual PII never stored or accessible in the platform.
No individual PII exposure
Aggregate mode ensures no team member can access or export individual-level personally identifiable information.
Same attribution quality
Data recovery and multi-touch attribution work identically in aggregate mode. Compliance doesn't mean losing data quality.
Transparent about every data point

The controls your legal team needs
CCPA & CPRA (California)
Opt-out tracking by default. Supports opt-in PII mode for consented users, or aggregate-only mode for maximum compliance. Built for California privacy law — North America-first.
Role-based PII access
Control exactly which team members can view or export individual-level data. Granular permissions so compliance teams can limit PII exposure by role.
Data retention controls
Set your own data retention window. Your data, your rules. Delete on your schedule.
Kleerr attributes known users. We don't identify anonymous visitors.
When a visitor provides their information (filling a form, logging in, completing a purchase), Kleerr connects that identity to their previous sessions. We never use probabilistic matching or third-party data to unmask anonymous visitors.
Known user attribution
When users identify themselves (purchase, form fill, login), we connect their journey.
Anonymous visitors stay anonymous
No probabilistic matching. No buying third-party identity data. Anonymous stays anonymous.
