Privacy Policy

Last updated: January 15, 2026

Our Privacy Promise

Rephyn is built with privacy as a core principle. Unlike most AI tools, we process your documents entirely on your device. Your legal documents, contracts, and sensitive information never leave your computer or phone.

Information We Collect

Account Information

When you create an account, we collect your email address and password (securely hashed). If you sign up with Google, we receive your email and name from Google.

Payment Information

Payment processing is handled by Paddle. We do not store your credit card details. Paddle may collect payment information as described in their privacy policy.

Usage Data

We track basic usage metrics like the number of documents analyzed (for subscription limits) and feature usage. We do not have access to the content of your documents.

Your Documents

We never collect, store, or transmit your documents. All document processing happens locally on your device using on-device AI. Your files stay on your computer.

How We Use Your Information

  • To provide and maintain our service
  • To manage your account and subscription
  • To send important service updates (you can opt out of marketing emails)
  • To respond to your support requests
  • To improve our product based on aggregated, anonymized usage patterns

Data Security

We use industry-standard security measures to protect your account information. Your documents benefit from the highest level of security—they never leave your device.
