Company principle

Software should remove friction, not create more of it.

  1. 01

    Focused by design

    Every product starts by deciding what it will not do. A narrow surface is easier to trust, faster to learn and cheaper to keep correct.

    Kitio ships one app with a small catalogue of modules rather than a suite of half-finished tools. You activate what you actually need and the rest stays out of the way.

  2. 02

    Dependable engineering

    Correctness is a feature. Entitlements are server-authoritative, offline caches are integrity-protected and the import pipeline validates before it trusts.

    The .kitio format is closed-whitelist at every level of its schema. Content is hashed, declared and verified — undeclared entries reject the entire file.

  3. 03

    Privacy as a foundation

    Data you never collect cannot leak. Kitio works without an account, shows no advertising and does not track you across other apps.

    There are no advertising identifiers, no cross-app tracking, no analytics and no crash reporting in this version. Your imported content stays on your device.

  4. Three commitments, one product. Everything below is Kitio keeping them.

Featured product — Kitio

Kitio is a single application with a catalogue of modules already built in. A redeem code or a .kitio file unlocks the one you need — no account, no advertising, nothing following you into other apps.

01 / 04One app, many modules

Activate only what you need.

Kitio ships as a single app with a catalogue of modules. Everything is already compiled in — a redeem code or a .kitio file simply unlocks the one you want and leaves the rest out of your way.

Available to unlock

02 / 04Kitio Focus

A day you can actually plan.

Plans carry a study area, a title, a date and time, a planned duration and a priority. The Today view keeps the running session, your focus goal and the day's plan in one place.

Session in progress

03 / 04Sessions

Pomodoro, countdown, stopwatch.

Three session types, each with rounds, breaks and its own history. Sessions record distractions and pauses, so the number at the end reflects the work rather than the clock.

Round 2 · Next: Short break

04 / 04Notes

Capture it while it is still fresh.

A block editor with Note, Checklist, Quick and Summary starting templates. Notes attach to a study area or a plan, and the library filters by pinned, favourite, recent, archived and trashed.

Technical note

What a .kitio file is

A portable, data-only package. It carries content and settings that parameterise a module already compiled into the app — the module is the engine, the file is the fuel.

Every file inside the package is declared with an expected SHA-256 hash and a whitelisted MIME type. Undeclared entries — or declared entries that are absent — reject the whole file.

  • Module targeting — which module and the minimum version required
  • Licence metadata — edition, issue and expiry, seat policy
  • Content — datasets and image assets, each integrity-hashed
  • Configuration — declarative parameters that tune the built module
  • Source code or bytecode of any language
  • Templates or expressions that get evaluated
  • Dynamic libraries, plugin binaries or anything loaded at runtime
  • URLs that auto-execute or deep-link to remote payload endpoints
Module explorer

Five modules. One catalogue.

Kitio Focus is the module with a full working experience today. The rest sit in the catalogue, ready to activate.

Privacy principles

Designed to be useful, not invasive.

These are the commitments Kitio actually ships with — each one is reflected in the app’s published privacy policy.

Kitio does not require an account, does not ask for your name or email to work, shows no advertising, and does not track you across other apps or sell your data.

Second product

Catkaya Software keeps a deliberately small product family. When there is something real to show, it will appear here with the same detail Kitio gets.

Third product

New products start only when an existing one is genuinely finished. This slot stays empty until that is true.

About Catkaya Software

A small studio with a long attention span.

Catkaya Software builds a deliberately narrow product family. Each release is finished before the next one starts, and every commitment on this page is one the shipping software actually keeps.

Operated by CATKAYA LIMITED

  • Data-only packages

    A .kitio file carries content and settings — never executable code. No scripts, no bytecode, no runtime-loaded binaries.

  • Server-authoritative entitlements

    Activation is verified on the server. The offline cache is integrity-protected and device-bound, and the app holds no private signing keys.

  • Closed-whitelist validation

    Every file inside a package is declared with an expected SHA-256 hash and an allowed MIME type. Anything undeclared rejects the whole import.

  • Encrypted local backups

    Backups are manual and encrypted with a password Kitio never stores. Nothing is uploaded to a cloud on its own.
