The Problem
The December 2025 incidents where Chrome extensions silently siphoned ChatGPT and DeepSeek conversations created a trust crisis in the AI privacy extension market. Astrix Security confirmed 900K users were compromised by malicious AI Chrome extensions. A Caviard.ai analysis found 67% of AI Chrome extensions actively collect user data. Users who specifically install privacy extensions are experiencing a security inversion: the tool they trust to protect their AI conversations is instead exfiltrating them. This is documented in Chrome Web Store reviews and security community Discord servers with significant engagement.
Key Data Points
- 67% of DPOs report insufficient resources to handle DSAR volume (IAPP 2025)
- 900+ GDPR enforcement actions concluded in 2024 across EU member states
- average GDPR fine increased 34% in 2024 vs 2023 (DLA Piper)
How anonym.company Addresses This
The Chrome Extension processes PII detection locally using the same Presidio-based engine. The anonymization occurs client-side before the modified prompt is submitted to the AI service. No intercepted conversation content is transmitted to anonym.legal servers. The extension's data flow is: intercept prompt → detect PII locally → anonymize locally → submit anonymized prompt to AI. This is architecturally distinct from extensions that "protect" by routing through their own proxy servers.
