Security you can hold.
QTComs builds software that secures everyday life: how you sign in, the secrets you keep and the data that's yours. Simple to use, private by design, and in your hands, not ours.

Your backup codes. On your body.
An encrypted vault on your NFC tag or implant: small files, protected by your password and your phone's security hardware. Offline: no cloud, no account.

Every colour, by name.

Private by design
We collect only what an app needs to work, and never sell or share it for ads. No tracking, no data brokers. Our apps today don't even have internet access: your data can't leave your phone.
Your keys, your data
Your secrets belong on devices you own and control, not on our servers. Security should be something you can hold.
Open standards
We build on open, widely reviewed standards such as FIDO2, Bluetooth and NFC rather than inventing our own, so our software works with what you already have.
