About MyColdKey

MyColdKey is built for anyone who wants to protect seed phrases and sensitive data with encryption that never leaves their device. We focus on offline-first, vendor-independent recovery so you stay in control.

Our product creates encrypted backups in multiple formats—QR codes, files, Shamir shares, and optional titanium plates—so you can duplicate, hide, and recover without depending on a single company or server.

Your data stays encrypted; we never see your seed.
