Terms of Service

Last updated: November 2026

These terms apply to the Singalong Solfege web app (webapp.singalong-solfege.com). The iOS app is provided under Apple's Standard License Agreement (EULA).

The web app is operated by Yasuhiro Sekine.

Singalong Solfege is an app for sight-singing classical songs with guide vocals and piano accompaniment. Some songs are free. A subscription unlocks all songs.

• The subscription costs US$50 per year, including tax. There is no monthly plan.
• It renews automatically every year until you cancel.
• You can cancel at any time from "Manage Subscription" in the web app. After you cancel, you can keep using the paid songs until the end of the period you have paid for.
• If the price changes, we will let you know by email before your next renewal. If you do not accept the new price, you can cancel and keep using the paid songs until the end of the period you have paid for.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

Refunds are handled by Paddle under the Paddle Refund Policy. To request a refund, contact Paddle at paddle.net within 14 days of your purchase. Paddle reviews each request. You can try the free songs before you subscribe.

• You sign in with your email address. Please keep access to that email address.
• One subscription can be used on up to 2 devices at a time. Signing in on a third device signs out the one signed in longest ago.
• The subscription is for your personal use. Please do not share your account with others.

The audio and sheet music in the app are for your personal practice. You may not redistribute, sell, or publish the MP3 or PDF files you save from the app.

We may update the app, add or change songs, or change these terms. If we make an important change to these terms, we will update this page and the "Last updated" date. We do our best to keep the service running, but we cannot guarantee that it will always be available.

The app is intended for educational and personal practice purposes only. The developer makes no guarantees regarding the accuracy or reliability of the content, and is not responsible for any issues, including but not limited to misinterpretation of musical content, technical difficulties, or data loss.
