Proton Mail's official iOS client for end-to-end encrypted email, written in Swift/SwiftUI with core business logic in a Rust-based SDK. The repository is published for transparency and currently cannot be built from source externally due to internal SDK distribution.
Use cases
- send and receive end-to-end encrypted email on iPhone
- access a privacy-focused email client on iOS
- review how a production encrypted mail client is architected
- study SwiftUI and Rust SDK integration patterns in a large app
- audit the iOS client code of Proton Mail
When to choose
- you want transparency into Proton Mail's iOS development and architecture
- you are studying how Swift apps bind to Rust core logic
- you want to inspect the UI layer of an encrypted email client
When to avoid
- you want to build, fork, or contribute to the app — it cannot be built externally and contributions are not accepted
- you need a fully open-source, self-hostable email client
- you need an email client for platforms other than iOS
