Cum pot opri echipa mea să lipească accidental datele clienților în ChatGPT?
Extensia Chrome a anonym.legal interceptă conținutul clipboard-ului înainte de a ajunge la chatbot-uri AI (ChatGPT, Claude, Gemini, DeepSeek, Perplexity), detectând și înlocuind automat PII cu token-uri anonimizate. Detectarea PII utilizează API-ul găzduit în UE al anonym.legal — nicio dată nu este trimisă furnizorului AI până când nu a fost igienizată. Extensia funcționează transparent, fără a necesita modificări ale fluxului de lucru din partea echipei dumneavoastră.
Extensii Chrome malițioase au furat 900,000 de conversații ChatGPT — cum pot ști că o extensie de confidențialitate este sigură?
Extensia Chrome a anonym.legal folosește Manifest V3 (cel mai recent standard de securitate Chrome) cu permisiuni minime — se activează doar pe site-urile chatbot-urilor AI pe care le activați explicit. Detectarea PII utilizează API-ul găzduit în UE al anonym.legal cu design zero-knowledge: textul este analizat în memorie și nu este stocat. Modelul optional_host_permissions al extensiei înseamnă că nu poate accesa niciun site pe care nu l-ați autorizat explicit.

Customer support AI receives customer messages with names, emails, AND order IDs. Standard PII tools strip email addresses but leave order IDs intact — partial anonymization that fails GDPR pseudonymization requirements. Here's the complete solution.
The Privacy Extension Paradox: How to Tell If Your AI Privacy Tool Is Actually Stealing Your Data
67% of AI Chrome extensions collect user data. The December 2025 incidents saw 900K users compromised by extensions posing as privacy tools. Average GDPR fine increased 34% in 2024. Here's the checklist for evaluating whether your privacy tool is trustworthy.
The 3.8 Daily PII Exposures Your Support Team Doesn't Know They're Making
Every support agent using ChatGPT makes an average of 3.8 sensitive data pastes per day. For a 100-person team, that's 380 GDPR exposure incidents daily. 63% of ChatGPT data contained PII in a 2024 EU audit. This is not a security problem — it's a workflow problem.
