This policy explains how this site uses browser storage. For broader information about data processing, see the privacy policy.
Browser storage
The tool uses browser storage to save preferences and preserve settings between visits. These values remain on your device and do not require an account.
The stored information may include:
| Information | Storage | Purpose |
|---|---|---|
| Label preference | localStorage | Preserve your chosen way of displaying notes and degrees. |
| Selected instrument | localStorage | Remember the last instrument you used. |
| Fretboard configuration | localStorage | Preserve the options selected for the diagram. |
| Theme | localStorage | Preserve your preference for light or dark theme. |
| Last tool page | sessionStorage | Make navigation easier during the current session. |
This site does not use an optional advertising or affiliate-cookie category, and it does not ask you to accept a cookie policy. You can remove browser storage at any time through your browser settings; some tool preferences will then return to their defaults.
No affiliate tracking
The site currently does not display product or affiliate links and does not load Skimlinks or another affiliate provider. No affiliate commission or affiliate cookie is created by this site.
Stripe checkout
The support button opens an external Stripe-hosted checkout. The panel uses separate fixed and custom-amount links for each locale and does not embed Stripe checkout in this site.
After you leave this site, Stripe may use cookies and other technologies needed for security, fraud prevention, and payment processing. Those technologies are controlled by Stripe on its checkout and are subject to Stripe’s own policies; this site does not receive or store your full card details.
