AI & music rights

How Moonsong uses AI

Moonsong uses AI models for the jobs below. Every AI action is started by you, shows its credit cost first, and runs only after you have allowed AI processing in the app.

Writing and editing lyrics yourself, the Song Blueprint, cover templates, title placement, playback and export don't use AI and are free. In "Song like…", looking up links and song names, recognising a song and analysing your humming on your iPhone are free too; only Analyze style costs a credit.

What is sent, and when

This is the AI processing notice you accept in the app (version ai-processing-2026-09-27).

• Nothing goes to an AI provider until you give permission in the app, and then only for the action you start.
• Music: your approved lyrics and Song Blueprint (genre, mood, vocal style and voice profile, instruments, exclusions, energy, pronunciation hints, timing notes) go to Google. For Song from a photo, the one photo you choose (or the AI cover you made) goes with it.
• Lyric help: your idea or instruction and the sections you asked it to change go to OpenAI. Locked sections cannot be changed, and every suggestion is shown as changes you accept or reject.
• Style analysis ("Song like…"): the titles, artists, genres and years of the references you confirmed, and any hum measurements (numbers only, never audio), go to OpenAI. Reference titles and artists are never sent to the music or cover model.
• Covers: an image description based on your project goes to Black Forest Labs.
• Safety: the text of each request, and the Style Profile from style analysis, is checked by Typesafe's classifier.
• Never used for training. Songs go directly to Google through its paid AI service, where Google doesn't use your content to improve its products. All other requests, and the music backup, pass through OpenRouter, and we ask it to use only provider routes that don't collect data for training (data_collection: deny). The providers are independent companies that may keep data for safety and abuse monitoring under their own policies, and may process it outside the EU/EEA, including in the United States.
• We don't send your email address, and we don't write your lyrics or prompts to our operational logs.
• You can withdraw permission at any time in Profile → Privacy & data. AI features stop; everything else keeps working.

AI-generated content is labelled

Songs, clips, AI covers and AI lyric suggestions are AI-generated, and Moonsong tells you so wherever they appear, in line with the EU AI Act's transparency rules (Article 50). The Creation Record in your export states which parts were AI-generated, and every shared song or playlist page is labelled "AI-generated with Moonsong". Providers may also embed their own watermarks or provenance signals in outputs; don't remove them.

If you publish something made with Moonsong, be open about the AI involvement where the law or the platform requires it, and never use it to make people believe a real person performed or said something they didn't.

Four different rights questions

"Can I use my song?" is really four separate questions, and Moonsong can only answer some of them:

1. What our Terms allow. We claim no ownership of your outputs and don't restrict how you use them beyond our Terms, the law and other people's rights.
2. Copyright protection. Whether your song, or your human contribution such as your lyrics, is protected by copyright depends on the law where you are and how much of the work is yours. Prompting alone is often not enough. We can't guarantee protection.
3. Other people's rights. Your inputs must be yours or used with permission. AI outputs can resemble existing works, so you remain responsible for how you use them.
4. Distribution. Distributors, streaming services and rights systems such as Content ID set their own rules for AI-generated music. We can't guarantee that any of them will accept, monetise or leave unclaimed a Moonsong output.

Your lyrics and inputs

• Use lyrics you wrote, or that you have permission to use.
• Don't ask for the voice, name or identity of a real artist or singer, or for a song that imitates them. Moonsong does not clone voices, and it does not upload or keep voice recordings: humming in "Song like…" is analysed on your iPhone.
• Names in your lyrics are fine when you're allowed to use them, for example a song for a friend's birthday. Pronunciation hints help the model say them.

Song like…

"Song like…" helps you start from music you love. Share a link to a track, album or playlist, type a song name, let Moonsong recognise a song playing nearby, or hum a melody. Moonsong turns that into a Style Profile: a short, generic description of the sound that you can edit before it goes into your Song Blueprint. What you get is an original song in a similar style, not a copy of anything.

• General style only. A Style Profile describes things like genre, mood, tempo, key, era, instruments, production and a generic vocal character (for example "breathy, airy female vocal"). We filter it so it contains no artist names, song titles, lyrics or "sounds like" phrasing, and our safety classifier checks it.
• Names never reach the music model. Titles and artist names are kept only as a private "Inspired by" note on your project. They are never sent to the music or cover AI; only the generic descriptors in your Song Blueprint are.
• No copying, no imitation. Moonsong doesn't copy melodies, lyrics or voices, doesn't imitate named artists, and doesn't accept audio uploads to continue or rework an existing piece of music.
• What humming does. Your iPhone measures the tempo, key, range, melodic shape and energy of what you hum. Only those numbers are used, and the recording never leaves your iPhone. Humming doesn't identify a song, and your melody isn't reproduced: its measurements can only shape the general style.
• Recognising a song. Listen uses Apple's ShazamKit on your iPhone to name a song playing nearby. It is simply a quicker way to add a reference, the same as typing its name.

Musical style in the general sense, such as a genre, a tempo or a choice of instruments, is shared by countless songs. A new song can still come too close to an existing one, so don't use "Song like…" to try to recreate a specific song, and listen critically before you publish. We can't guarantee that an output won't resemble an existing work: the rights questions above still apply, as do notice and takedown and appeals. How your references are handled as data is explained in the Privacy Notice.

The Creation Record

Every export can include a Creation Record: a small file describing how your song was made. It includes when it was generated, which models and versions were used, a fingerprint (hash) of the output file, your lyric revisions, the Terms and policy versions you had accepted, and which parts were AI-generated.

It is useful as your own record of the workflow. It is not a copyright certificate, not proof of exclusive ownership and not legal clearance.

Notice and takedown

If you believe content made with Moonsong infringes your rights, or that someone has used your lyrics or identity without permission, email support@sansavision.com with the subject "Rights notice" and include:

• your name and contact details, and whether you act for someone else;
• the work or right you believe is infringed;
• where you found the content and why you believe it came from Moonsong;
• a statement that the information is accurate and that you believe in good faith the use is not authorised.

For a song or playlist shared by link, include the link (moonsong.my/s/…) or use the Report link on that page. Other Moonsong projects are private, so we may not be able to locate content that has been exported and published elsewhere. We review every notice, act on valid ones (for example by removing content, turning off shared links, and restricting sharing or closing accounts that repeatedly infringe), and tell the affected user unless the law prevents it.

Appeals

If an automated safety check blocked your request, or we removed content or restricted your account, you can ask for a person to review the decision. Email support@sansavision.com with the subject "Appeal", the project name and roughly when it happened. We'll review it and tell you the outcome and our reasons.
