Terms of Service

Last updated: 2026-07-19

FluentSong is a language-learning service that lets you study YouTube songs with synced lyrics, translation, and AI analysis. By using the service you agree to these terms.

What we provide

We embed YouTube videos via the official YouTube IFrame Player. We do not host or distribute audio or video files. Lyrics shown in the player are auto-generated from YouTube subtitles or transcribed from audio for educational use; copyright in the underlying lyrics belongs to the respective rights holders.

Pricing and plans

Listening to, reading and studying any song already in FluentSong is free for everyone, with no account required. What is limited is creating new lessons, because that is what costs us to produce:

• Without an account, you can add a small number of new songs per day, drawn from a shared daily pool.
• With a free account, you get your own guaranteed allowance each day (currently one new song and ten line explanations), independent of that shared pool, and can study in your own language. The daily allowance does not accumulate.
• Pro is a paid subscription (currently $4.99/month or $39/year) that raises those limits to a monthly allowance you can use whenever you like, and unlocks generating translations in any supported language. Billing and cancellation are handled by Stripe; you keep Pro until the end of the period you have paid for.

These allowances are fair-use limits that we may adjust over time. If we change them we will keep the pricing page current; any change will not remove lessons you have already generated.

Acceptable use

Don't use FluentSong to scrape, redistribute, or republish YouTube content. Don't attempt to interfere with the service or other users.

Account, AI and data

Accounts and sign-in are handled by Better Auth (email/password or Google). Payments, if you subscribe to Pro, are handled by Stripe; we never see or store your card details. AI features (translation, song analysis, lyric lookup, artist bio) are powered by OpenAI. Data you submit (URLs, language preferences) may be sent to OpenAI for the purpose of generating lyrics, translations and analysis.

Liability

The service is provided "as is" with no warranties. We are not liable for indirect, consequential or incidental damages.
