Open Source Kotlin Cloud Storage Software

A fully-featured client to access your Cloud Storage provided by MEGA.

Proton Drive for Android is Proton’s official Android client codebase for accessing Proton Drive from phones and tablets, built as a full native Android application that you can compile and run in Android Studio or from the command line. The repository is structured like a typical production Android app with a Gradle-driven build, and its setup guidance emphasizes straightforward local development workflows as well as headless builds for CI-style environments. It is designed to plug into Proton Drive’s broader ecosystem so users can manage their cloud-stored files from an Android interface while keeping the client implementation transparent and reviewable as open source. The project documentation focuses on developer setup details such as SDK configuration and build commands, which is especially useful for engineers auditing or reproducing official builds.

CloudGallery is an Android photo backup application that uses Telegram Bot API as a storage destination for personal image collections. It uploads photographs directly to a configured Telegram account without routing files through an additional application server. Smart synchronization detects changes and helps keep backed-up images current. An integrated gallery allows users to browse previously synchronized photos. Authentication information, including bot tokens and chat identifiers, is protected through Android Keystore encryption. A local JSON database records image identifiers and metadata for restoring backup history. Users can export and import this database when changing devices. CloudGallery uses a Material 3 interface and does not include analytics or tracking. Uploaded images are not end-to-end encrypted.
