Your computers
One key unlocks Pro on 3 computers at a time. Moving to a new one, or lost one? Free its seat here, then activate Pro on the new computer.
It’s in your purchase email from Gumroad. Only the key’s owner can see or free its seats.
How seats work
1Add a computer
Open Hertz Sync on it, click Get Pro and paste your key. It takes one seat.
2Move to a new one
In Hertz Sync on the old computer: Pro, then Deactivate on this computer. Or free its seat here.
3Tell them apart
Each computer has a name like “Windows PC · 7F3A”. Hertz Sync shows it under Pro.
Good to know
- Reinstalling on the same computer
- Uses no new seat. Activate again with the same key.
- Freeing a seat here
- That computer goes back to the free plan at its next check, at the latest within 14 days if it stays offline. Your library and settings stay.
- What we keep
- A one-way hash of your key, and for each seat an anonymous computer id, its name and the date. No email, no computer or user name, nothing about your sounds.
- Need help?
- Reply to your Gumroad purchase email and we’ll sort it out.
