Local-first, always
All of your data lives in a local database on your own device. Nothing is sent anywhere unless you explicitly turn on sync — and then it is end-to-end encrypted, so the server cannot read it either.
luma
Budgeting, a password manager, a file converter, notes and an AI assistant — plus 34 optional plugins, from a QR generator to a transit simulator. Everything is local-first: your data lives on your own device, and nothing leaves it unless you turn on sync.

Built into every install
These ship with the app whether you want them or not — which is why there are only nine of them. Click any one for the full story.
The one screen you actually look at
Eight conversion tools, none of them a website
Budgeting that never asks you to sign up
A vault that works offline, including the breach check
Somewhere to put the thing before you forget it
Three speeds, or bring your own key
Install only the tools you actually want
Two lavenders and a rail you can rearrange
Optional, and encrypted before it leaves
And 34 more, optional
Each plugin is self-contained — its own data, its own page, its own icon in the sidebar. The ones you never install cost you nothing.
Install and manage Minecraft instances — Vanilla, Fabric, Forge, NeoForge and Quilt — with mod, resource pack and shader pack downloads, Java management, and live launch logs. Inspired by modern launchers, built with luma's own design.
DetailsA transit simulator on the real world: pick any city on Earth and build metro, tram, bus and train networks on a live 3D OpenStreetMap map. Trains only call at real stations and run on tracks that really exist; buses and trams pathfind along real streets. A commuter simulation fed by real land use decides, trip by trip, whether your network beats the car.
DetailsEverything for school in one place: homework planner, flashcards with spaced repetition, a formula library, a study timer, an assignment tracker, GPA and grade calculators, citation generator, weekly timetable, and mind maps.
DetailsAn everyday calculator that turns into a graphing one. Basic mode handles the daily sums; Advanced adds a scientific keypad and plots any number of functions of x on a pannable, zoomable graph you can tap to trace. The ☰ button in its header converts measurements — km to miles, °C to °F, kg to pounds, and more.
DetailsEvery photo and video on this device, sorted into tabs: pictures and videos from the camera, screenshots, GIFs, and one tab per folder — WhatsApp, Downloads, whatever else is there. See where shots were taken on a world map, and on Nova let on-device models sort them by what's in them.
DetailsBuild a server-hosting empire right inside luma. Buy rigs and routers, spec them with real CPUs, motherboards, RAM and cooling, host services, accept contracts, and manage power and bandwidth as you grow day by day. Now with a phone-friendly layout, offline earnings, a six-branch research tree, daily goals and timed boosts.
DetailsFinance
Five tabs — overview, transactions, pots, recurring and stocks — all stored locally. Stock prices come in keyless from Stooq with a Yahoo fallback, so there is no API key to register for.
Assistant
Aurora is fast, Nebula is smarter, Pulsar is smartest — served through Luma's own proxy with a fair per-user allowance. Or point it at your own Anthropic, OpenAI, Mistral or Google key.
Password Manager
Every password and 2FA secret is encrypted at rest with its own device-local key. The breach check runs against a list bundled with the app — your plaintext password never leaves the machine to be checked.
Calm by design
All of your data lives in a local database on your own device. Nothing is sent anywhere unless you explicitly turn on sync — and then it is end-to-end encrypted, so the server cannot read it either.
Nine modules ship built in. Everything else is a plugin you install one at a time, and each one keeps to its own page and its own data.
No badges begging for attention, no streaks, no notifications you didn't ask for. Two lavender themes, a sidebar you can drag into your own order, and then it gets out of the way.
Free, and free of accounts
Every push to master builds Windows, Linux, Android and iOS. Grab the newest run — the artefacts are attached to it, and the app's own updater checks the same releases.
The iOS build is unsigned — resign it with a free Apple ID using AltStore or Sideloadly before installing.
