Connected Vehicle Privacy Firewall and Data Blocker

C7/10June 8, 2026

WhatA hardware/software device that plugs into a car's OBD-II or telematics port to block unauthorized location and telemetry data from being transmitted to manufacturers and their partners.

SignalMultiple commenters express deep frustration that modern vehicles constantly transmit location and driving data to manufacturers like Toyota, GM, and others — and that even with new laws, the data collection itself is the real harm, not just the sale of it.

Why NowGM's $12.75M fine for reselling OnStar data has made vehicle telemetry a mainstream concern, new cars are increasingly connected by default, and state privacy laws are giving consumers legal backing to demand control over their data.

MarketPrivacy-conscious car owners pay $100-300 for the device; 280M registered vehicles in the US, even 1% penetration is $280M+. Existing OBD blockers are crude and can disable useful features — there's no smart, selective solution.

MoatHardware plus continuously updated firmware for new vehicle models creates a two-sided moat; community-contributed vehicle profiles build a defensible dataset of manufacturer telemetry behaviors.
