Privacy
Stem Buddy works on your Mac. Your audio, your Logic projects and your track names stay on your Mac. Here’s everything that does leave it, and why. Last updated October 26, 2026.
Usage statistics (on by default, easy to turn off)
After each finished export, Stem Buddy sends: how many files were bounced, how long it took, the app version, the edition, and a random ID created for your installation. Never song, track or file names, folder paths or audio. They’re collected with Google Forms, so Google processes them for us.
To turn them off: Stem Buddy menu › Share Usage Statistics.
Update checks
About once a day, Stem Buddy downloads a small signed file from this website to see if there’s a new version. The request contains nothing about you or your music; like any web request, our host (Cloudflare) sees your IP address.
Done alerts (optional, off until you set them up)
- Text (iMessage): sent by the Messages app on your own Mac, from your own Apple account. It goes through Apple, not through us.
- Email: Stem Buddy sends your email address, how the export ended (for example “complete”) and how many files were made to our alert relay, which runs on Google Apps Script and sends the email with Gmail. It keeps a count of emails per address for one hour to prevent abuse, and nothing else.
Both only ever say how the export ended and how many files were made, never song or track names.
Trial download
To download the free trial you give us your email. It’s stored in a Google Form (Google processes it for us). We use it to send a few tips while you try Stem Buddy, and news and offers only if you ticked that box. Reply “stop” to any email and we’ll remove you.
Free trial and licence
The 7-day trial is tracked on your Mac only (a file plus a Keychain entry), with no account and no server. When you buy, our store, Lemon Squeezy, handles payment and your purchase details under their own privacy policy. Stem Buddy checks your licence key with Lemon Squeezy once when you enter it, then about once a day when online. It sends only the key and an anonymous install label, never your Mac’s name.
Reports you choose to send
If something goes wrong, “Save report…” makes a file you can choose to email us. Stem Buddy never sends reports by itself. Reports leave out song names, project names and your user name.
