Notalune. Terms of Use

Last updated: 2026-07-12

1. What Notalune is

Notalune is a tool that runs entirely on your device. It photographs printed sheet music you point it at, overlays note names for your personal study, and stores the results only on your device. Notalune has no servers: it never receives, hosts, transmits, or distributes your photos or annotations. In this respect it is like a camera and a pencil.

2. Your content, your responsibility

• You may use Notalune only with sheet music that you own or otherwise have the right to use (e.g., purchased scores, public-domain works, your own compositions, or materials your teacher licensed to you).
• Annotated pages, exports, and prints are intended solely for your personal study.
• Copyright in the underlying sheet music remains with its rights holders. Notalune gives you no rights to it. Distributing, publishing, or sharing copies of copyrighted sheet music, annotated or not, may infringe copyright, and you alone are responsible for such use.
• Note for users in the Czech Republic/EU: statutory private-use exceptions are narrow and, for printed sheet music, paper reproduction is largely excluded from the reprography exception (Directive 2001/29/EC art. 5(2)(a); § 30a of the Czech Copyright Act). Printing a copyrighted score may therefore require the rightsholder's permission even for private use. When in doubt, print only works you may lawfully copy (e.g., public-domain or licensed editions permitting copies).

3. No liability for user infringement

Notalune (daylight.studio) provides a general-purpose annotation tool with substantial lawful uses. We do not monitor, receive, or control what you scan, and we accept no responsibility or liability for copyright infringement or other unlawful acts committed by users with the app. If you use Notalune with content you have no rights to, that is your choice and your liability.

4. Reading accuracy

Note names are produced by on-device recognition and may be incomplete or wrong. Notalune deliberately leaves uncertain notes blank. The output is a study aid, not an authoritative edition; verify against your score.

5. Free tier and Notalune Pro

Notalune Pro is a one-time purchase processed by Apple; payments, refunds, and Family Sharing follow Apple's App Store terms. The free tier includes the complete reading and correction tools, the full metronome, and practice (training) mode, with these limits (current as of this version; the app's paywall screen is authoritative):

• 10 quick readings in total (a one-time allowance, not a daily one; it does not reset);
• 3 saved pieces, with 1 page per piece;
• printing and sharing of annotated PDFs is available in Notalune Pro only.

Notalune Pro removes all of the above limits permanently. No subscription.

6. Privacy and the optional improvement program

Notalune collects no data. See the privacy policy at https://notalune.com/privacy.

The optional, off-by-default "Help improve recognition" feature stores small image crops of your corrections locally on your device; nothing is transmitted automatically. If you choose to send us these crops manually (via the share sheet), you confirm that you may lawfully share the photographed material with us for this purpose (see Section 2), and you grant us the right to use the submitted crops solely to develop and improve Notalune's on-device recognition. We do not publish or redistribute submitted crops, and we delete them from our working set once incorporated into training (details and your GDPR rights: privacy policy, section 5).

7. Changes

We may update these terms; the current version is always at https://notalune.com/terms. Continued use after a change means acceptance.
