The problem that made me build this
Every time I signed up for a new app or service, I clicked "I Agree" without reading a single line. Nobody reads Terms of Service. They're 30+ pages of dense legal language designed to be ignored.
But I kept hearing horror stories:
- Apps training their AI on your private photos
- Subscriptions auto-renewing for €99/year after a free trial
- Platforms stripping your right to sue them (forced arbitration)
- Companies sharing your data with hundreds of "partners"
So I built ToS Radar PRO — a Chrome extension that reads the fine print so you don't have to.
How it works
The extension uses AI to scan any Terms of Service or Privacy Policy page and flags six categories of dangerous clauses:
AI/Data Scraping — "We may use your content to train our AI models"
Forced Arbitration — You waive your right to take them to court
Auto-Renewals — Subscription traps buried in paragraph 47
Data Sharing — Your data sold to advertisers and data brokers
Unilateral Changes — They can change the terms anytime without notice
Account Termination — They can delete your account for any reason
The key architectural decision: everything runs locally in your browser. No API calls, no external servers, no data leaving your machine. Pure privacy.
Tech stack
- Chrome Extension Manifest V3
- Vanilla JavaScript (no frameworks — keeping it lean)
- Local AI inference via the browser
- Zero external dependencies
What I found while testing
After running it against 50+ popular websites, here are the most common traps:
97% of apps reserve the right to train AI on your data
83% include forced arbitration clauses
76% have auto-renewal terms that are hard to find
100% reserve the right to change terms at any time
The worst offenders? Social media platforms and productivity SaaS tools.

Would love feedback from the DEV community — especially on the tech approach and features you'd want added. What clauses do you care about most?
