About BinForce

A small team that takes software seriously

We believe good software comes from clear requirements, restrained design and solid engineering. Based in Hong Kong and working with clients locally and overseas, we hold every project — from a small internal tool to an enterprise platform — to the same standard.

01

Clear communication

We talk about technology in language you understand. Scope, risks and progress are always visible — no black boxes.

02

Engineering quality

Readable code, testable architecture, maintainable systems. We ship products that last, not one-off demos.

03

In it for the long run

Launch is the beginning. We stay to read the data, adjust the direction and keep iterating as your business grows.

What we do

From idea to launch,
one team

Our product

PassNote傳紙條

A messaging and mail app built for teams. Notes, email and contacts live in one place — content protected by account-held keys, workflows connected through an open platform.

Messages and mail, together

Handle notes and email in one place. No more hopping between apps, no more scattered conversations.

Private Letter · account keys

Every account holds its own key, and content travels encrypted. The key stays with you — the important things belong only to the right people.

Open platform & bots

Bring system alerts, approval requests and everyday workflows into the conversation through APIs and bot interfaces — so a message can become an action.

Company directory

Find colleagues and contacts quickly. Shorter paths to the people you need, easier onboarding for new joiners.

Security architecture

Privacy isn’t a setting.
It’s the architecture.

PassNote keeps message content with you, not on our servers. Data lives on your mail server and on the device; every account is guarded by its own key, so privacy is the default.

ZERO RETENTION

Zero message retention

Message content never enters our storage. It stays on your mail server and on the phone — data ownership stays where it belongs.

PER-ACCOUNT KEY

Per-account keys

Each account holds its own key, and content is encrypted in transit and at rest. Without your key, the data cannot be read — even if it leaves the device.

OPEN PLATFORM

Open platform & bots

APIs and bot interfaces connect alerts, approvals and internal tools to the conversation. Private by design, open by integration.

Deployment can follow your existing mail server and compliance requirements.

How we work

Visible progress, delivered outcomes

Four clear stages. You always know what we are doing and why we are doing it.

  1. 01

    Discover

    Understand the business goals, users and constraints. Define the problem and the metrics for success together.

  2. 02

    Design

    Validate direction with wireframes and clickable prototypes, then move into visual design and a design system.

  3. 03

    Build

    Two-week iterations with continuous demos and course-correction. Transparent progress, early risk detection.

  4. 04

    Launch

    Release, monitor, support and iterate. The product keeps growing after it goes live.
