Main OS
A calm personal system for life and work

Everything that matters. One clear place.

Plan your day, move your goals forward, and see life and work together—without giving up privacy or ownership of your data.

Your personal space

A system that adapts to your life.

From your next decision to your long-term direction, every surface is designed to reduce noise and increase clarity.

A clear day

One focus task, a realistic timeline, and daily routines without dashboard overload.

Deeper execution

Projects, tasks, checklists, tags, and useful views that move ideas into action.

Goals that move

Connect the big picture to today without artificial points or pressure.

Time and money together

Plan time and track accounts, transactions, and assets with clear currency boundaries.

Privacy by design

MFA, revocable sessions, export and deletion, with strict boundaries around private workspace content.

Across your devices

Start on the web, install Android from Google Play, and use Windows after Store certification completes.

From thought to a finished day

Three steps keep you close to what matters.

You do not need to build a complex system before you begin. Capture, decide, and review.

  1. 01

    Capture

    Add the task or thought before it disappears.

  2. 02

    Organize

    Place it in a project, day, or goal and choose the next clear action.

  3. 03

    Review

    Return to your day, progress, and decisions in one calm view.

Trust is not an add-on

Your data is yours. That is an operating rule.

Main OS is built around explicit ownership, narrow permissions, and an audit trail for sensitive operations.

  • Integrations stay off until you consent
  • No silent overwrite of source-owned data
  • Export, deletion, sessions, and devices remain under your control

FAQ

Good questions before you begin

Is Main OS only a task manager?+

No. Tasks are the starting point; goals, routines, time, money, health, and connected work live in one personal system.

Can platform administrators read my workspace?+

The control plane does not expose private workspace content. It handles operational identity, subscription, and account state only.

What happens to connected-system data?+

The source remains authoritative. Main OS stores identifiers, sync state, and a minimal projection without silently replacing remote data.

Are the apps available now?+

The web app is available, and Android can be installed from Google Play. Windows will be available after Microsoft Store certification.
