Privacy Policy

Last updated: January 16, 2026

At ByeMail, we believe privacy is a fundamental right. This policy explains how we handle your data with complete transparency.

Our Core Principles

  • We never read your email content. We only access email headers.
  • We never sell your data. Unlike competitors, your privacy is not our product.
  • Minimal data collection. We only store what's necessary to provide the service.

What We Access

When you connect your Gmail account, we request permission to:

  • Read email headers (From, Subject, List-Unsubscribe)
  • Execute one-click unsubscribes via HTTP (RFC 8058)
  • Move emails to Trash (reversible for 30 days)
  • Restore emails from Trash (undo capability)

What We Store

  • Your email address (for account identification)
  • Encrypted OAuth tokens (AES-256 encryption)
  • Anonymized action history (which domains you unsubscribed from)

Data Retention

All data is automatically deleted after 90 days of inactivity. You can delete your account and all associated data at any time from Settings.

Advertising

  • Personalized ads: With your consent, Google may use cookies to show ads based on your interests.
  • Non-personalized ads: If you decline ad cookies, you'll still see ads, but they won't be based on your browsing history.
  • Opt out: You can manage your ad preferences at any time via our cookie settings or through Google's Ad Settings.
