Write to hello@octava.music. One person reads it, so tell us what you were doing, what you expected, and what happened instead. If it is about a specific song, include its link.

For anything about your data, including a copy of it or its deletion, use the same address and say so in the subject line.

Open Library and check the song. A generation that failed on our side returns its credits automatically, usually within a few minutes. If the credits have not come back after an hour, write to us with the song link.

Credits and Pro are attached to your account rather than to a device, so signing in on another device is not the problem. If a purchase completed in the store but the credits are not on your account, send us the store receipt and we will fix it by hand.

Refunds go through Apple or Google, because they took the payment. We cannot issue them ourselves.

If a published song impersonates someone, infringes your copyright, or breaks the rules in our terms, tell us with a link to it. We read every report and we answer.

Settings has the option, and it removes your profile, your songs and your files. It cannot be undone, so download anything you want to keep first.
