1. Introduction

Welcome to PrivMsg ("we," "our," or "us"). These Terms of Service ("Terms") govern your access to and use of our secure end-to-end encrypted messaging service.

By accessing or using our Service, you agree to be bound by these Terms. If you disagree with any part of the Terms, you may not access the Service.

2. Transparency and Privacy Commitment

PrivMsg is built on the principles of full transparency and strong privacy. Our commitment includes:

  • End-to-end encryption with 2048-bit RSA keys
  • No access to message contents or private keys
  • Minimal data collection – only what is strictly necessary
  • Complete user control over encryption keys and data

Your messages are encrypted on your device before transmission and can only be decrypted by the intended recipient. We do not collect or store any personally identifiable information beyond your username.

3. Account Creation and Security

To use PrivMsg, you only need to provide a unique username and password. We do not collect emails, phone numbers, or other personal identifiers.

You are responsible for maintaining the confidentiality of your credentials and must notify us of any unauthorized access to your account.

4. Encryption Key Management

PrivMsg enforces strict encryption policies:

  • Your private key is never stored on our servers.
  • We only store your public key to allow message encryption.
  • You are responsible for backing up and securing your private key.
  • If you lose your private key, we cannot recover your messages.

5. Legal Compliance

While we prioritize user privacy, we comply with applicable legal obligations. However:

  • We collect minimal user data.
  • We do not store or have access to message content.
  • We do not track user activities.

Any lawful request for data will be constrained by our minimal data collection and encryption-first architecture.

6. Acceptable Use

You agree not to use the Service for any prohibited activities, including:

  • Illegal or fraudulent activities
  • Unauthorized security testing or penetration testing
  • Distributing malware or engaging in cyber attacks
  • Spamming or unauthorized data collection

7. Service Availability

While we aim to provide a reliable service, we do not guarantee uninterrupted availability. We reserve the right to modify, suspend, or discontinue the Service at any time.

8. Termination

We may terminate or suspend your account without notice if you violate these Terms. Upon termination, you will lose access to the Service.

9. Limitation of Liability

PrivMsg and its affiliates shall not be liable for any indirect or consequential damages, including loss of data, privacy, or profits resulting from the use or inability to use the Service.

10. Changes to These Terms
