Terms of Service

1. Scope

These Terms set out the conditions for using Undertone Archive (the "Service"). The Service collects interpretations of song lyrics, mainly Vocaloid and internet-born songs, organizes them song by song as each writer's archive, and lets readers vote on whether they agree. By using the Service, you agree to these Terms.

These Terms are provided only in Japanese and English. They apply even if you use the Service in another language.

2. Accounts

• Posting interpretations, voting, registering songs and adding statements require signing in with a Google account. Reading public interpretations does not.
• You may not create an account if you are under 13, or under 16 if you live in the European Economic Area or the UK.
• If you are a minor, please get the consent of a parent or guardian before creating an account.
• You are responsible for your account. Do not let others use it.
• The Service is free of charge.

3. Interpretations you post

• **Interpretations must be written by you. You may not post interpretations written by AI (such as generative AI).** The Service's prompting feature only returns questions and never writes the text.
• **The Service is not a place to publish lyrics.** Quote only the lines your interpretation needs, briefly and in quote blocks, so that your interpretation is the main part and the quotes are secondary. Each quote may be up to 30 full-width characters (60 half-width), the total per interpretation up to 90 full-width characters, and your own text (excluding quotes) must be at least twice the total of the quotes. Interpretations beyond these limits cannot be published. Name the song as the source of each quote (and the lyricist if you know it).
• **Images cannot be posted.** There is no feature to post images, including images or screenshots of music videos and covers. Describe music videos in your own words rather than transcribing them.
• Writers choose the visibility (public, unlisted, private) and whether to show their name. Public interpretations can be read by anyone, including people who are not signed in. Interpretations whose writers allow translation may be shown with an AI translation.
• Do not import or repost other people's interpretations. You may only import interpretations you published yourself on other sites or in videos.
• Copyright in your interpretations stays with you. You grant the Service permission to use them to the extent needed to provide the Service (display, grouping by song and by line, showing translations, display when shared, and search).

4. Registering songs and statements by artists

• Register songs and artist names as accurately as you can. The operator may correct registered songs and names to unify notation or merge duplicates.
• Add statements by artists or official sources with their source (URL, outlet, or the date and venue of a live event), summarized in your own words. Keep quotes from statements short. Statements from live events are shown as unverifiable information, and those from ongoing tours are shown collapsed.
• If an artist or rights holder asks that what was said at a live event not be spread, we handle it through removal requests.

5. Voting

• Vote after reading the interpretation. Who voted and how is not shown to other users, including the writer.
• Anything that distorts the agreement ratio is prohibited, such as voting with multiple accounts, voting on request or for payment, or voting by automated means. Abnormal votes may be excluded from the tally.

6. Prohibited conduct

• Conduct that violates laws or public order and morals
• Defamation of specific people such as creators, singers, other writers or fans, discriminatory expressions, or sexual content
• Posts whose text attacks a specific writer (the Service has no place for rebuttals)
• Impersonating others, or presenting statements that were not made as statements by an artist or official source
• Reproducing all or most of a song's lyrics, including by splitting them across several interpretations
• Infringing the rights of others (copyright, portrait rights, privacy, etc.)
• Posts intended to advertise or lead people to external sites
• Interfering with the operation of the Service, or excessive access by automated means
• Fraudulent clicks on ads or inflating impressions
• Copying, modifying or reverse engineering the Service

7. Reports, removal requests and actions

The Service accepts reports on public interpretations, statements and testimonies (sign-in required) and removal requests from people without an account. Reports alone do not hide content, but if several users report defamation or misattribution, the content may be hidden temporarily until the operator reviews it.

After review, the operator may hide interpretations or statements, or exclude votes from the tally. When an interpretation is hidden, the reason is shown to its writer, who may appeal once.

Users who violate these Terms may receive, in order, a warning, a temporary posting restriction, and account suspension. Suspended accounts cannot sign in, and all their interpretations are hidden. A suspended Google account cannot be registered again.

8. Leaving

You can delete your interpretations and statements yourself at any time. You can leave the Service yourself from the "Data and leaving" settings page. We will delete your profile, the accounts you imported from, your private interpretations, your votes, and your confirmations and testimonies on statements. You can choose whether your public and unlisted interpretations and the statements you added are deleted or kept anonymously. Interpretations imported from elsewhere are deleted either way, because the link to the original post would identify you.

9. Disclaimer

• The Service is provided as is. We do not guarantee fitness for a particular purpose or uninterrupted availability.
• We are not liable for damages caused by interruption of the Service, loss of data or delays.
• Disputes over the content of interpretations or statements are to be resolved between the parties. The verification mark on statements only shows the result of mechanically checking whether the same words appear in the source, and does not guarantee that the content is correct.
• The agreement ratio is a tally of users' votes and does not indicate whether an interpretation is correct.

10. Changes to and termination of the Service

We may change the Service or stop providing it. If we stop, we will give notice in advance where possible.

11. Governing law and jurisdiction

These Terms are governed by the laws of Japan. Any dispute concerning the Service shall be subject to the exclusive jurisdiction of the Kobe District Court as the court of first instance.

12. Changes to these Terms

If we change these Terms, we will post the new content and the revision date on this page.
