Zayvay deliberately doesn't give brands access to these things.
No viewer PII. Ever. Not name, email, phone, address, IP, device fingerprint, real birthdate. Even brands paying for disclosed demographic targeting only see anonymized rows — never information that re-identifies a real person.
No private demographic fields. A viewer who marked their income as "private" doesn't show up to brands targeting income. You can't see, count, or target on fields the viewer kept private.
No cross-campaign viewer tracking. Anonymous viewer IDs are unique per campaign. The same viewer answering your Premium Nasq twice across two campaigns gets two different IDs. You can't build a viewer profile from multiple Nasqs.
No retargeting. You can't target viewers who saw a previous campaign of yours. You can't target viewers who visited your site. You can't target viewers who interacted with you anywhere.
No specific-creator targeting. You see which creators your Nasq ran on after the fact. You can't bias toward or away from specific ones in your targeting. (See Why you can't target creators by name.)
No partial completion data on Access Nasqs. If a viewer abandoned mid-Nasq, you know it didn't complete — you don't know how many seconds in they left.
No cross-brand data. What viewers do for other brands isn't visible to you. The platform doesn't tell you a viewer's full Nasq history.
These aren't oversights. They're the platform's privacy contract, and it's a meaningful part of why viewers trust Zayvay enough to share demographic data in the first place. Loosening any of them would erode the system that makes the data you do get valuable.
