StringinoTerms of Use
Last updated: October 11, 2026
These terms govern your use of the iOS app "Stringino" (the "App") provided by Masaki Naito ("we"). By using the App you agree to these terms. Apple's Standard End User License Agreement (EULA) also applies.
1. What the App does
The App is a practice aid: it listens to your playing and compares it with the score. Results (pitch and rhythm feedback, and scores read by scan import) are approximations and are not guaranteed to be correct.
2. Pro (auto-renewing subscription)
- Scan import is part of Pro (600 JPY per month in Japan, tax included; renews monthly). Prices may differ by country or region.
- Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the end of the period.
- Manage or cancel your subscription any time in Settings → your Apple Account → Subscriptions. Refunds are handled under Apple's policies.
- Scan import is limited to 20 pages per month (reset on your renewal date). It may be temporarily unavailable when the service is busy.
3. Copyright of sheet music
Only scan or import music you have the right to use. Use copyrighted music only within private use. We are not responsible for how you use sheet music.
4. Prohibited use
Unauthorized access to the App or servers, excessive load, reverse engineering, and use that violates law or third-party rights are prohibited.
5. Disclaimer
We make no warranty about the App's operation, the accuracy of its results or its fitness for a particular purpose. To the extent permitted by law, we are not liable for damages arising from use of the App.
6. Changes and termination
We may change the App or these terms. Continued use after a change means you accept it.
7. Governing law
These terms are governed by the laws of Japan.
