Messages 0.1.3 for Linux

Messages for Linux, packaged as an x86_64 Flatpak with the shared Luma UI.

Sign in to Luma Hub, enter a one-time connection code, and message other Luma accounts with end-to-end encryption. Device credentials use Secret Service. The native helper receives credentials through a sealed memory descriptor. The package also includes the existing Google Messages and WhatsApp helpers.

Install:

flatpak install --user ./Messages-0.1.3-x86_64.flatpak
flatpak run org.projectluma.Messages//standalone

The bundle uses GNOME Platform 50 and contains a Luma Depot signature. Application and packaging source, matching dependency sources, and checksums are attached.

Verified on Ubuntu: signed package installation, desktop launch, live Luma sign-in, native helper connection, and sign-out removing the saved device credential. Live encrypted send/receive was also verified between the native clients. Google Messages and WhatsApp account linking was not exercised against their live services in this release check.

Voice Memos 0.1.1

Voice Memos for Linux, packaged as an x86_64 Flatpak with the shared Luma UI.

Record, pause, resume, play, rename and export Ogg/Opus recordings. The phone layout includes explicit recording-name controls. The bundle uses GNOME Platform 50 and includes only the selected application dependencies.

Install:

flatpak install --user ./VoiceMemos-0.1.1-x86_64.flatpak
flatpak run org.projectluma.VoiceMemos//standalone

A desktop microphone and PulseAudio-compatible audio service are required for recording. Automatic transcription is not included.

Application and packaging source. Corresponding dependency sources, source hashes and checksums are attached. The Flatpak contains a Luma Depot signature.

Verified on Ubuntu: installation, desktop launch, saved-audio playback at 1× and 1.5×, and recording/pause/resume/save/rename through an isolated PulseAudio input. Physical microphone and speaker testing remains device-specific.

Tasks 0.1.2 for Linux

Tasks for Linux, with LumaUI and the existing responsive task interface.

Download Tasks-0.1.2-x86_64.flatpak, then install and launch:

flatpak install --user ./Tasks-0.1.2-x86_64.flatpak
flatpak run org.projectluma.Tasks//standalone

Uses the shared Freedesktop Platform 25.08 runtime, which downloads from Flathub if needed. Luma Platform is not required.

Tasks uses the host's Evolution Data Server and standard VTODO records. Connect supported accounts through GNOME Online Accounts, or configure other CalDAV task lists in Evolution. Lists and offline caches are shared with other desktop EDS clients. This bundle does not provide a separate Luma Connect sign-in.

Verified on Ubuntu 24.04: task creation and editing, stale-edit protection, completion and undo, comments, persistence after restart, deletion and restore, responsive layouts, desktop launch and authenticated HTTPS CalDAV create/edit/complete/delete between two clients. Credentials are stored by the desktop keyring.

The bundle is signed. SHA256 checksums, the public signing key, source receipt and dependency source inputs are attached.

Notes 0.1.0 for Linux

Notes 0.1.0 for x86_64 Linux, available as a signed Flatpak and an AppImage.

Write rich-text notes, organize pages and folders, and sync your account library
with Luma Hub. Sign-in uses a browser connection code and the desktop keyring.
Notes on this computer stay in a separate local library.

Install with Flatpak

Download Notes-0.1.0-x86_64.flatpak, then:

flatpak install --user ./Notes-0.1.0-x86_64.flatpak
flatpak run org.projectluma.Notes//standalone

Flatpak downloads the shared Freedesktop 25.08 runtime from Flathub if needed.
Install a later release bundle to update Notes.

AppImage

Download Notes-0.1.0-x86_64.AppImage, make it executable and open it.
Without FUSE, use --appimage-extract-and-run. Saving a sign-in requires a
desktop Secret Service keyring, such as GNOME Keyring or compatible KWallet.

Tested on Ubuntu 24.04.5 LTS. SHA256SUMS covers the release files;
luma-depot.gpg is the public Flatpak signing key. The dependency source archive
is optional and is not needed to run Notes.

Application and packaging source
remain in the Luma source repository.

Notes-0.1.0-dependency-sources-corrected.tar contains the corrected dependency source inventory and supersedes the original source archive. Application downloads are unchanged.

Leaf 0.1.0 for Linux

Leaf 0.1.0 for x86_64 Linux, available as a signed Flatpak.

Read EPUB books, save reading progress, bookmarks and highlights, and browse
Calibre or OPDS libraries. Read aloud uses the desktop voice service or the
included eSpeak NG basic voice.

Install

Download Leaf-0.1.0-x86_64.flatpak, then:

flatpak install --user ./Leaf-0.1.0-x86_64.flatpak
flatpak run org.projectluma.Leaf//standalone

Flatpak downloads the shared GNOME Platform 50 runtime from Flathub if needed.
Install a later release bundle to update Leaf. The Luma desktop and Luma Platform
are not required. Library passwords use the desktop Secret Service keyring.
Reading state is saved locally; this release does not include Luma Connect
reading sync.

Tested on Ubuntu 24.04.5 LTS, including EPUB rendering, desktop file opening,
saved reading state, keyring storage, TLS checks and both read-aloud paths.
SHA256SUMS covers the release files; luma-depot.gpg is the public Flatpak
signing key. The dependency source archive is optional and is not needed to run
Leaf.

Application and packaging source
remain in the Luma source repository.

Leaf-0.1.0-dependency-sources-corrected.tar contains the corrected dependency source inventory and supersedes the original source archive. Application downloads are unchanged.

Charlie 0.2.14 for Linux

Charlie 0.2.14 for Linux, packaged as an x86_64 Flatpak with its selected LumaUI dependencies. Requires GNOME Platform 50, downloaded from Flathub when needed.

flatpak install --user ./Charlie-0.2.14-x86_64.flatpak
flatpak run org.projectluma.Charlie//standalone

Accounts and mail remain in the application sandbox; saved credentials use the desktop Secret Service keyring. The package runs its own mail engine. HTML messages block sender scripts and remote images by default.

Validated on Ubuntu with native UI and HTML privacy checks, credential storage, and local TLS mail fixtures. Live third-party mail accounts were not used for validation.

Source · Build and installation

The Flatpak is signed with the included Luma Depot public key. Dependency source inputs and SHA256 checksums are attached. Install a later bundle to update Charlie.

Calendar 0.1.1 for Linux

Calendar for Linux, with LumaUI and the existing responsive calendar interface.

Download Calendar-0.1.1-x86_64.flatpak, then install and launch:

flatpak install --user ./Calendar-0.1.1-x86_64.flatpak
flatpak run org.projectluma.Calendar//standalone

Uses the shared Freedesktop Platform 25.08 runtime, which downloads from Flathub if needed. Luma Platform is not required.

Calendar uses the host's Evolution Data Server. On GNOME, connect supported accounts through desktop Online Accounts; other CalDAV accounts can be configured in Evolution. Calendars and offline caches are shared with other desktop calendar clients. This bundle does not provide a separate Luma Connect sign-in.

Verified on Ubuntu 24.04: event editing, recurrence, all-day dates, time zones, reminders, import/export, responsive layouts, desktop launch and authenticated HTTPS CalDAV create/edit/delete between two clients. Credentials are stored by the desktop keyring. Opening cached calendars no longer waits for a network connection-state flag.

The bundle is signed. SHA256 checksums, the public signing key, source receipt and dependency source inputs are attached.
