Why Terms of Service Documents Matter
Studies have repeatedly found that almost nobody reads the terms of service or privacy policy before clicking "I Agree" — and it's not hard to see why. A typical app's combined ToS and privacy policy can run 5,000–15,000 words of dense legal language, sometimes longer than a short novel chapter, written in a style optimised for legal precision rather than human readability.
Yet these documents govern real things: what happens to your personal data, whether you can sue the company if something goes wrong, whether a subscription silently renews and charges you, and how much control you actually have over your own account. This tool won't replace reading the document, but it gives you a fast way to know which sections are worth reading closely.

How This Analyzer Actually Works
Being upfront about this matters: this tool does not use artificial intelligence or language understanding. It works through straightforward keyword and phrase matching — searching your pasted text for wording commonly associated with ten categories of clauses that tend to matter to consumers, then showing you exactly where each match was found.
This approach has real limits (covered honestly in the Limitations section below), but it has one big advantage: it is completely predictable, runs instantly, and needs no external service — your document never leaves your browser.
Understanding Your Readability Score
The Flesch Reading Ease score is a well-established readability formula based on two factors: how long your sentences are on average, and how many syllables your words tend to have. Longer sentences and longer words push the score down (harder to read); shorter sentences and simpler words push it up (easier to read).
| Score Range | Reading Level | Typical Example |
|---|---|---|
| 90–100 | Very Easy (5th grade) | Children's books |
| 70–90 | Easy to Fairly Easy | Casual blog posts, conversational writing |
| 60–70 | Standard (8th–9th grade) | Most newspapers and general web content |
| 30–50 | Difficult (college level) | Academic papers, technical manuals |
| 0–30 | Very Confusing (graduate level) | Legal contracts, dense terms of service |
The 10 Red-Flag Categories Explained
Data Sharing & Selling
Flags language about sharing or selling your personal data to third parties — often for advertising or analytics purposes.
Tracking & Cookies
Flags mentions of cookies, tracking pixels, or device fingerprinting used to monitor your activity, often for building an advertising profile.
Arbitration & Legal Rights
Flags clauses requiring disputes to go through private arbitration instead of court, sometimes alongside a class-action waiver.
Auto-Renewal & Billing
Flags subscription language indicating automatic renewal and recurring charges unless you actively cancel.
Policy Changes Without Notice
Flags language allowing the company to change the rules at any time, sometimes without directly notifying you.
Liability Limitation
Flags clauses limiting what you can hold the company responsible for, even when something goes wrong on their end.
Data Retention
Flags language about how long your data is kept — including cases where it's retained even after account deletion.
Third-Party Access
Flags mentions of affiliates, service providers, or law enforcement who might gain access to your information.
Account Termination
Flags conditions under which your account can be suspended or terminated, sometimes at the company's sole discretion.
Children's Data & Age Requirements
Flags language about age restrictions or handling of data from minors — relevant if the service could reach younger users.

Worked Example
A clause reading: "We reserve the right to share your personal information with our advertising partners and third-party service providers at our sole discretion."
This single sentence would trigger flags in two categories — Data Sharing & Selling (because of "share your personal information" and "advertising partners") and Third-Party Access (because of "third-party service providers"). Seeing both flags on the same sentence is a strong signal that this specific clause deserves a careful read.

Frequently Asked Questions
No. This tool uses rule-based keyword and pattern matching, not artificial intelligence. It scans your pasted text for known categories of risky clauses and calculates a readability score — it cannot understand meaning the way a human or an AI would.
No. This tool is an educational aid to help you focus your reading. It is not a substitute for legal advice — for decisions with real consequences, consult a qualified lawyer.
It searches your pasted text for common phrases associated with ten categories of clauses that frequently matter to consumers, showing where each was found along with a plain-English explanation of what that category typically means.
A widely used formula estimating how difficult text is to read, based on average sentence length and syllables per word. Scores range from 0 (very difficult) to 100 (very easy). Most terms of service documents score quite low.
Yes. Because it relies on keyword patterns rather than true understanding, it can miss unusually phrased clauses and may flag harmless phrases too. Always read the full document, especially highlighted sections.
No. All analysis happens instantly inside your browser using JavaScript. Nothing you paste is uploaded, logged, or stored on any server.
They're written by lawyers for legal precision and liability protection, which often produces long sentences and dense vocabulary — pushing their readability score toward the difficult end of the scale.
A high flag count doesn't automatically mean the document is unfair — many standard, legitimate services include clauses like arbitration or liability limitation. Use the flags as a starting point to read those sections closely.
