Privacy Policy

Last updated: 12 June 2026

Fingerline ("we", "us") makes a tool that adds cello fingerings to sheet music. We built Fingerline to respect your privacy. This policy explains what we do and don't do with your information.

The short version

Fingerline does not require an account, does not ask for personal information, and does not sell or share data with advertisers. Your scores stay on your device.

Information we do not collect

• We do not collect your name, email address, or contact details.
• We do not require sign-up or create user accounts.
• We do not access your camera, microphone, location, or contacts.
• We do not show advertising or use advertising trackers.

Files you import

Sheet music you open, scan, or pick from the library is processed to add fingerings. Your saved scores and preferences are stored locally on your device (in your browser's local storage) and are not uploaded to us.

Score scanning & search

When you scan a PDF or search the public-domain library, your request is sent to our score-processing service solely to perform that scan or search and return the result. We do not use these requests to identify you, and we do not retain the files after processing. The service also fetches public-domain scores from third-party libraries (such as the Mutopia Project and IMSLP) at your request; their use is governed by their own terms.

Performance video

If you use Performer Mode with a YouTube link, the video is embedded directly from YouTube and is subject to Google's privacy policy. Local video files you choose are read on your device only and are not uploaded.

Children

Fingerline is suitable for all ages and does not knowingly collect any personal information from anyone, including children.

Changes

If this policy changes, we will update this page and the date above.
