Why Privacy Matters When Analyzing Legal Documents

When you upload a contract to a cloud-based AI tool like ChatGPT, that document becomes part of their system. Your NDA, employment agreement, or lease—complete with names, addresses, salary figures, and other sensitive details—is now sitting on someone else's servers.

The Hidden Cost of "Free" AI Tools

Most AI tools are free because you are the product. Your documents may be:

• Used to train future AI models
• Stored indefinitely on cloud servers
• Accessed by company employees for "quality assurance"
• Subject to data breaches or government requests

For legal documents containing sensitive business information or personal details, this is a serious concern.

What Makes Rephyn Different

Rephyn takes a fundamentally different approach: your personal data is anonymized locally before any AI analysis.

Here's how it works:

1. Local Anonymization: Names, addresses, phone numbers, and other personal details are detected and stripped in your browser
2. Only Anonymized Text is Analyzed: The AI sees "[PERSON_1]" and "[ADDRESS_1]" instead of your actual information
3. Your Identity Stays Private: We analyze the legal clauses and risks, not your personal details
4. Original Document Stays Local: Your actual file never leaves your device

Why This Matters for You

Consider what's in a typical employment contract:

• Your full legal name and address
• Salary and compensation details
• Social security or tax identification numbers
• Non-compete clauses revealing your employer's competitors
• Confidential business information

With Rephyn, the AI might see something like: "[PERSON_1] agrees to a salary of [AMOUNT_1] per year..." instead of your actual name and salary. The legal analysis is just as accurate, but your personal information is never exposed.

The Bottom Line

When choosing a legal document analyzer, ask yourself: What happens to my personal data?

With Rephyn, your personal information—names, addresses, phone numbers, and other sensitive details—is stripped out before analysis. We help you understand legal documents without ever seeing who you are.
