Every line of it open source

Software that minds its own business

Notes, mail, calendar, files, tasks and more. Built properly, priced fairly, and with no interest whatsoever in what you keep inside them.

No AI assistants. No tracking. No adverts. Not now, not later.

What we actually promise

Six commitments. Each one is either visible in the source code or it is not a commitment at all.

  • Private by design

    No tracking, no profiling, no advertising, no third-party analytics. Each service collects what it technically needs to function, and stops there.

  • Open source, all of it

    Every client and every server, not just the bits that are safe to show. Promises are cheap; a public repository you can compile yourself is not.

  • No AI, anywhere

    No assistants, no summaries, no "smart" suggestions quietly reading your data to justify a valuation. Tools that do the thing you asked, and only that.

  • Priced like a utility

    One subscription covers the entire ecosystem. The price follows how much storage you need and how many people share it — no per-product tiers, no feature withheld for a higher price, and no "contact sales".

  • Craft over churn

    Small, careful releases. Keyboard-first, properly accessible, quick on the hardware you already own, and translated by people who speak the language.

  • Yours to take

    Open formats and one-click export in every app. Self-host the whole stack, or walk out with your data intact. Leaving should be boring.

One ecosystem, not a bundle of acquisitions

Everything shares one account, one design system and one set of rules. Here are the pieces we are building first.

  • Status: Alpha

    Numori Notes

    Notes that do the maths for you

    A plain-text notepad with a natural-language calculator built into every line. Write "48 GBP in EUR" or "12% of 340" and the answer appears beside it, no separate calculator needed.

    What you need: No account needed
  • Status: Pre-alpha

    Numori Clips

    A clipboard with a memory and a filter

    A clipboard manager that keeps your history on your machine, recognises code and formats it properly, and refuses to record anything from the apps you tell it to ignore.

    What you need: No account needed
  • Status: In development

    Numori Mail

    An email client that is only an email client

    A fast, private client for the mailbox you already have — any IMAP or SMTP account, whoever runs it. No assistant offering to write your replies and no engine reading your post. A Numori-hosted mail service will follow later, priced separately from storage.

    What you need: No account needed
  • Status: In development

    Numori Drive

    Storage that cannot read what it stores

    End-to-end encrypted file storage with ordinary sharing, ordinary folders and no content scanning. Files go up encrypted, and the server never sees the keys.

    What you need: Free account
  • Status: In development

    Numori Calendar

    A calendar that keeps your schedule to itself

    Encrypted events with proper recurrence, real time-zone handling and invitations that work with everyone else's calendar. Your diary is not training data.

    What you need: No account needed
  • Status: In development

    Numori Tasks

    Tasks, not a productivity philosophy

    Lists, projects, due dates and recurrence, with an offline-first store and keyboard-first navigation. No streaks, no scoring, no nudges.

    What you need: No account needed

How this differs from the usual arrangement

A fair comparison against how a large privacy suite is typically put together, not against any one company.

Numori compared with a typical large privacy suite
NumoriThe usual arrangement
Open source The entire ecosystem, clients and servers Clients only, and often not all of them
AI features None, as a matter of policy Added yearly, usually on by default
Tracking None, including on this website Product analytics and marketing pixels
Pricing One subscription, every product Per-product tiers that add up quickly
Self-hosting Supported and documented Enterprise plans, if at all
Getting your data out Open formats, one click, no support ticket Partial exports in proprietary formats

    Why there will never be AI in Numori

    Refusing to add AI features is not nostalgia or a marketing angle. It is the only position consistent with the other promises we have made.

    Open source has to include the servers

    Publishing a client while the server stays closed proves almost nothing. Here is what an open client actually tells you, and what it does not.

    Building eighteen apps with one design system

    Numori UI started as a components folder inside the notes app. Extracting it taught us more about accessibility than about component APIs.

Read the code before you trust the pitch

Every repository is public, including this website. Have a look at what is finished, what is half-built, and what is still only a plan.

Most people will never pay us a penny

No app needs a subscription and nine of the thirteen need no account at all, so for most of the people using Numori there is nothing to buy. Donations pay for the servers those free apps run on — the storage nodes, the sync relay, the build machinery. No perks, no donor tiers, no name in a credits file unless you ask.
