Hi @AceRimmer
All of your Roon data is stored in your Roon database — As long as your database is still there, you can renew your subscription and start back with Roon right where you left off.
I’d also recommend making a backup and storing it in a safe location. That way, if you choose to return to Roon, even if something happened to your Core machine in the meantime or you just want to use a different device, you can ensure that all of your Roon data is safely kept in the backup and can be restored once you join back up.
If you have any other questions please let us know!
