Security at MailPrism

Your email is personal. We've built MailPrism with security and privacy at its core — not as an afterthought.

Security Practices

Encryption Everywhere

All data is encrypted in transit using TLS 1.3 and at rest using AES-256. Your credentials and tokens are encrypted with additional application-level encryption.

Row Level Security

Database-level isolation ensures users can only access their own data. Even our own engineers cannot access your information without explicit authorization.

Privacy by Default

Tracking pixels are blocked by default. Email content is processed in memory and never stored permanently. We only retain metadata necessary to provide our service.

Secure Authentication

We support passkeys (WebAuthn), multi-factor authentication, and secure OAuth 2.0 for Gmail integration. We never see or store your Gmail password.

How We Handle Your Data

What we store

  • Email metadata (sender, subject, timestamps) for tracking and automation
  • Your automation rules and preferences
  • AI-generated summaries (cached for performance)
  • Audit logs of actions taken

What we never store

  • Your Gmail password — we use OAuth 2.0, always
  • Email attachments — accessed directly through Gmail
  • Full email body content — fetched fresh from Gmail each time (unless you opt-in to AI training)

Optional: AI Training Data

When you provide feedback on AI responses to improve your experience, that specific email content may be stored. This is entirely opt-in, and you can delete your training data at any time from your settings.
