§ 02 — Practice

Two sides of the same studio.
Apps I make. Software I help others make.

The product studio

Five apps in market, each built around a single principle: your data stays on your device. No tracking, no telemetry, no surprises in the terms.

§ 05 — Common questions

The short answers
to the usual questions.

What is Modern Logic Tech?

An independent software studio run by Matthew Choo in Seri Kembangan, Malaysia. Two sides: consumer apps sold directly on the App Store and Microsoft Store, and direct freelance engagements for founders building modern software.

Do your apps track me?

No. Every app ships with the same default: no analytics, no telemetry, no behavioural pings. Your data stays on your device. Where sync is needed (like iCloud), it happens inside your own account — never on a server we control.

What platforms are your apps on?

iOS, macOS, Windows, Android, and browser. Different products cover different platforms — Luxebook is iOS/macOS/Windows, BiblioFuse covers iOS/Android/Web/Windows, LokalTools runs in any browser. See the full catalogue.

How do I hire you for a project?

Email support@mlogictech.com with a short brief — what you're building, rough timeline, rough budget. A free 30-minute scoping call follows. Two project slots are open per quarter; lead time is typically a few weeks.

Is it really one developer?

Yes. Matthew designs, engineers, and supports every line of work that ships under this name. No account managers, no outsourcing. Small by design — because that's the only way to care about every commit.
