Proton Drive for iOS

Proton Drive for iOS is the official iPhone and iPad client repository for Proton’s end-to-end encrypted cloud storage service, intended to securely back up and share files within the Proton ecosystem. The project is built around Apple’s native toolchain and is designed to be opened as an Xcode workspace, reflecting a production-grade iOS app structure with standard signing and provisioning requirements. It includes a stated trust model section, reinforcing that the client is meant to be scrutinized and understood as part of a privacy-first architecture rather than treated as a black box. Dependency management is handled through Swift Package Manager, keeping builds consistent and minimizing external tooling complexity for contributors and auditors. While it is open source and positioned for public review, the repository explicitly indicates that contributions are not accepted at the moment, which signals a controlled development and release pipeline.
