AI-Powered

Smart replies, email categorization, thread summaries, and spam detection — all powered by on-device AI models. Nothing leaves your phone.

Secure by Design

Face ID and Touch ID app lock. OAuth tokens stored in Apple's hardware-encrypted Keychain. Your credentials never touch our code.

🔍

Fast Search

Full-text search across all your emails with semantic understanding. Find what you need by meaning, not just keywords — instantly and locally.

📧

Gmail Support

Secure OAuth integration with Gmail. No passwords stored — only industry-standard authentication tokens, safely kept in iOS Keychain.

Zero Tracking

No analytics. No ads. No data collection. No device fingerprinting. We don't even have servers to collect your data on.


Everything stays on your device

VaultMail connects to Gmail via secure OAuth. Your emails are fetched over IMAP and stored locally using SwiftData. AI models run on-device using Apple's Foundation Models and CoreML. We operate zero servers.
