01 / WHAT IT CATCHES

The red flags companies bury in fine print.

ClauseLens tests contracts against strict, deterministic heuristic rules. No vague summaries or hallucinations—just clear detection of provisions that compromise your rights.

High SeverityArbitration

Forced Arbitration & Class Action Waivers

Strips your constitutional right to take disputes to public court or join collective class action lawsuits, forcing private binding arbitration.

"...disputes shall be resolved solely by individual binding arbitration. You waive any right to bring claims as a class member..."
High SeverityBilling

Silent Automatic Subscription Renewals

Flags recurring credit card billing traps, narrow cancellation notice windows, and automatic renewal rate increases before they charge your card.

"...subscriptions automatically renew for successive terms unless cancelled at least 48 hours prior to the conclusion of the billing cycle..."
High SeverityData Brokers

Personal Data Sale & Third-Party Sharing

Exposes permissions allowing services to share, syndicate, or sell your device telemetry, browsing behavior, and personal records to advertising brokers.

"...we may share pseudonymous advertising identifiers, location telemetry, and usage patterns with our certified marketing partners..."
Medium SeverityAmendments

Unilateral Terms Modification

Catches clauses claiming the company can alter fees, service terms, or privacy commitments at any time without explicit individual notice.

Info / LowLiability

Draconian Liability Caps & Disclaimers

Pinpoints clauses capping company financial responsibility to minimal amounts (often $50 or one month's fee) even in cases of data loss or service downtime.

"...in no event shall our total liability exceed the greater of fifty dollars ($50.00) or the amount paid by you in the preceding month..."

02 / SILENT CHANGE DETECTOR

Catch stealth updates before you re-agree.

Companies constantly update their terms and quietly strip user rights. ClauseLens fingerprints every document locally. When a policy changes, it calculates an instant diff showing exactly what was altered.

06 / FREQUENTLY ASKED QUESTIONS

Got questions? We have answers.

Everything you need to know about local processing, security, and clause detection.

How does ClauseLens protect my privacy?

We strictly do not collect any data. ClauseLens is engineered from the ground up so that zero document text, page URLs, or personal data is ever transmitted to any external server. All heuristic analysis and source mapping executes entirely within your browser's isolated local tab.

Does ClauseLens track what websites I visit?

No. We strictly do not collect any browsing history, URLs, or telemetry. Document recognition runs entirely client-side without pinging any tracking server.

Does ClauseLens provide formal legal advice?

No. ClauseLens is an educational and productivity tool designed to help consumers and professionals quickly navigate dense agreements. It identifies commonly contested clauses and red flags, but does not substitute for qualified legal counsel.

How does the document diff engine work?

When you analyze a document, ClauseLens stores a cryptographic hash and normalized structure in your browser's local extension storage. When you revisit that policy in the future, it compares the new text against the previous snapshot and reveals added or removed clauses.

Can I use ClauseLens on internal enterprise agreements?

Yes. Because ClauseLens operates 100% locally with a strict zero-data policy, you can safely use it on confidential enterprise terms, non-disclosure agreements, and intranet policies without violating data governance rules.
