A state-by-state read for a student-worn device that captures classroom audio, processes voice, and handles children's data — and what that legal terrain does to the addressable market.
The label is mechanical, derived from three stacked layers, so a partner's lawyer can check the logic rather than trust an opinion.
Layer three (student-data law) rarely moves the verdict because some statute applies in roughly 40 states; it functions as a near-universal baseline obligation rather than a differentiator.
"No live listening / raw audio deleted" is mostly irrelevant to consent law. Most eavesdropping statutes trigger on the act of recording or interception, not on whether a human listens live or how briefly audio is retained. The product's restraint architecture is a trust story, not a legal exemption.
Classroom expectation of privacy is genuinely unsettled. Several in-person statutes hinge on whether a conversation was "private." A classroom is arguably semi-public, which can cut either way and is exactly the kind of question that ends up litigated.
Bullying / voice analysis is the biometric trigger. If the system builds or matches voiceprints to identify speakers, it crosses from recording law into biometric law. That is what makes Texas — one-party for recording — a watch item rather than a clear green.
Currency. These regimes move (Illinois rewrote its eavesdropping statute after a 2014 ruling; biometric and comprehensive-privacy laws are multiplying). Re-verify before any model goes external.
One-party consent baseline. States may impose stricter all-party rules on top; they cannot go below this.
Governs education records. Directly binds federally-funded schools; reaches vendors through the school's contract, not directly.
Under-13 data. Verifiable parental consent, data-minimisation, deletion rights. Central to a child-worn device.
SOPIPA / SUPER-style statutes bar commercial use and ad-targeting of student data and impose direct liability on operators.
Three tiers, weighted by the students who actually live in each. The point of the market tab is that the legal map is lopsided: a few large states swing the totals far more than the colour counts suggest.
Allowed states form the clean launch footprint: one-party consent, no aggressive biometric regime. Contested states are layered on as a conditional tier — reachable, but each carries an unresolved consent or biometric question that should be priced as risk, not assumed. Forbidden states are excluded from the addressable base.
Weighting uses NCES public K-12 enrollment so a state counts for its student population, not as one of fifty equal squares. Private and homeschool students (~4-5M nationally) sit on top of these figures and would lift every tier modestly.
This is a market-sizing instrument, not a media plan. A green state is addressable in principle; individual districts within it can still bar the device, so bottom-up ZIP and district screening still governs where spend actually goes.
