Horse Browser is licensed per person, not per machine. If you use a laptop and a desktop, install it on both. If you sometimes work off a borrowed machine, install it there too. The only thing the licence asks of you is not sharing your account with someone else.
Installing on another device
Download the relevant version on each machine and enter the same licence key you used on the first one. That's the whole process.
What about syncing between devices?
Horse doesn't talk to a cloud. Everything is stored locally on whichever machine you're on, which is the privacy story but also the inconvenience: a Trail you opened on your laptop won't appear on your desktop on its own.
For now, the workaround is the import/export feature: export from one machine, import on another. Sync is on the roadmap, designed so it doesn't compromise the privacy story. No date yet.

The offline backup guide covers exporting your full Trail history to a file you can keep separately.
