About CYAN PRO APP
We build utility software for Vietnamese users and sell it with account-based licences rather than loose activation keys.
What we do
CYAN PRO APP is a small software team that writes and ships its own products. Each one solves a specific everyday job: cutting video, scanning documents, sharing files across a local network, chatting on a LAN. We take no client project work; all of our time goes into the products you see in the catalogue.
How we sell software
- Licences belong to an account, not to a key file. Move to a new machine and you sign in again rather than asking for a new code.
- Each plan sets how many machines may run at once. When a machine dies or is sold, you release its slot yourself from the dashboard.
- Updates within your licence period are free. We do not charge for a mid-term upgrade.
- Some apps are free with no time limit, some are sold by plan, some are still in testing. The label on each card says which.
What we hold ourselves to
- We ship only through cyanpro.app. Builds hosted elsewhere are not ours and licences will not accept them.
- We never sell or rent user data to anyone.
- No bundled adware, no changed browser homepage, nothing running in the background beyond what you asked for.
- If we broke it, we fix it — including when the fault appears outside the plan period.

A phone call or Zalo message during office hours is fastest. Outside those hours, email us — we reply the next working morning.
