Privacy Policy

Last updated: February 18, 2026

Overview

Ephemeral is designed with privacy as a core principle. We believe in collecting the absolute minimum amount of data necessary to provide our service. This privacy policy explains what information we collect, why we collect it, and how we protect it.

Privacy by Design

We don't have accounts, we don't track users, and we don't store secrets longer than necessary. Your secrets are encrypted and automatically deleted after being viewed or when they expire.

Data We Collect

Information You Provide

  • Secret Content: The text you submit to create a secret. This is encrypted immediately upon receipt and cannot be read by us.
  • Optional Password: If you choose to protect your secret with a password, we store a secure hash of that password (never the password itself).
  • TTL Selection: Your chosen expiration time for the secret.

Automatically Collected Information

  • IP Address (Hashed): We collect a SHA-256 hash of your IP address for rate limiting and abuse prevention. We do not store your actual IP address.
  • Timestamps: When secrets are created and accessed.
  • User Agent (Hashed): A hash of your browser's user agent string for security monitoring.

What We Do NOT Collect

  • Email addresses
  • Names or personal identifiers
  • Location data (beyond IP-based country for compliance)
  • Tracking cookies or analytics
  • Decrypted secret contents

How We Use Your Data

Data Purpose Legal Basis (GDPR)
Encrypted secrets Provide the core service Contract performance
Hashed IP address Rate limiting, abuse prevention Legitimate interest
Timestamps Enforce TTL, security auditing Legitimate interest
Password hash Verify access to protected secrets Contract performance

Data Retention

We follow a strict data minimization approach:

Secrets

Deleted immediately after being viewed, or automatically when TTL expires (maximum 30 days).

Encryption Keys

Deleted together with their associated secrets. Never stored permanently.

Audit Logs

Retained for 30 days for security purposes, then automatically purged.

Data Security

We implement industry-standard security measures to protect your data:

  • Encryption at Rest: All secrets are encrypted using authenticated encryption (AES-256-GCM or XSalsa20-Poly1305).
  • Encryption in Transit: All connections use TLS 1.3 with HTTPS.
  • Key Separation: Encryption keys and encrypted content are stored in separate systems.
  • Zero-Knowledge Architecture: We cannot decrypt your secrets even if compelled to.
  • Automatic Deletion: Secrets self-destruct after viewing or expiration.

For more details, see our Security Policy.

Depending on your location, you may have the following rights regarding your data:

  • Right to Access: Request information about data we hold about you.
  • Right to Deletion: Request deletion of your data (secrets auto-delete by design).
  • Right to Rectification: Correct inaccurate data (not applicable as we don't store personal data).
