Write to support@gracenote-app.com. Tell us which device you're using and what happened.
A song imported wrong
Send us the link to the page you shared, or the file, and a screenshot of how it looks in GraceNote. Chord sites change their pages; your example helps us fix the importer for everyone.
Keeping a copy of your songs
Your songs live on your device, and your iPhone or iPad's iCloud backup includes them. Exporting songs and GraceNote's own backup come with Pro.
Deleting your data
There's no account, so your songs are only on your device. Settings › Data › Delete all data removes them; deleting the app does too.
