Guitar profile questions, answered
Where are my guitar profiles stored?
They're saved privately in your own browser using local storage. Nothing is uploaded to a server, so your profiles stay on the device you created them on. The trade-off is that clearing your browser data removes them, so tap Export backup now and then to save all your guitars to a file you can re-import later.
Can I back up my profiles or move them to another device?
Yes. Tap Export backup to download a single file holding all your guitars. Keep it somewhere safe, and if you ever clear your browser data or switch to a new device, tap Import backup and pick that file to bring every guitar back. Export and Import is the surest way to keep your setups; Print / Save as PDF is handy for a paper copy in the case.
Do I need an account?
No. There's no sign-up and no login. Add a guitar and it's saved instantly on your device.
What should I record in a guitar profile?
Anything that helps you recall a setup: bridge type, scale length, string gauge and tuning, action at the 12th fret, neck relief, nut and pickup heights, and the dates of your last setup and string change. Every field is optional except the name.
