Privacy Policy

Last updated: January 2026

1. Introduction

Eleidon ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our secure messaging service.

Our core principle is simple: your messages belong to you. We use end-to-end encryption to ensure that only you and your intended recipients can read your messages.

2. Information We Collect

Account Information

  • Your Eleidon address (e.g., name@eleidon or name@yourdomain)
  • Hashed password (we never store plaintext passwords)
  • Public encryption keys (for establishing secure channels)
  • Account creation date and plan type

Message Metadata

  • Sender and recipient addresses
  • Timestamps of messages
  • Delivery status

We cannot read your message content. All messages are end-to-end encrypted before leaving your device.

What We Do NOT Collect

  • Message content (encrypted on your device)
  • Private encryption keys (stored only on your device, or encrypted in Vault)
  • Your recovery phrase (unless you opt into Vault backup)

3. Vault Backup Service

If you enable Vault backup, your recovery phrase is encrypted with your password before being stored on our servers. We use industry-standard encryption (AES-256-GCM) and cannot access your recovery phrase without your password.

You can disable Vault at any time, which will delete your encrypted backup from our servers.

4. How We Use Your Information

  • To provide and maintain the Eleidon service
  • To process trust requests between users
  • To deliver messages to intended recipients
  • To send service-related notifications
  • To prevent abuse and maintain security

5. Data Sharing

We do not sell, rent, or share your personal information with third parties for marketing purposes.

We may share information only in the following circumstances:

  • With your explicit consent
  • To comply with legal obligations
  • To protect our rights and prevent fraud
  • With service providers who assist in operating our service (under strict confidentiality agreements)

6. Data Retention

We retain your account information for as long as your account is active. Encrypted messages are stored until deleted by users. You can request account deletion at any time, which will remove all associated data from our systems.

7. Security

Security is at the core of Eleidon. We implement:

  • End-to-end encryption for all messages
  • Zero-knowledge architecture where possible
  • Regular security audits
  • Secure infrastructure with encryption at rest and in transit

8. Your Rights

You have the right to:

  • Access your personal data
  • Correct inaccurate data
  • Delete your account and associated data
  • Export your data
  • Object to certain processing activities

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
