What we hold, and what you can do about it

What we hold

Your identity: the name you go by, and — once you agree to your first split — your legal name, performing-rights organisation and IPI number. Optionally a photo, a bio, a location and links.

Your work: the parts you record or upload, the songs you are on, the percentages you agreed to, and any declaration you made about AI use.

Your conversations: messages you send and receive, and the notes a Head of Song sends when they pass on a part.

Why we hold it

The legal identity exists for one reason: a split sheet has to name a real person and their rights organisation, or nobody can be paid. It is used for that and nothing else. We do not sell it, we do not advertise against it, and we do not share it with anyone who is not on the same song as you.

Your percentages and credits are shown to the people on that song, and to industry accounts you have published to. Everyone else sees a sealed sheet — no names, no percentages, not even how many people are on it.

Why we are allowed to hold it

To run the service you signed up for (UK GDPR Article 6(1)(b), a contract): your account, the songs you are on, your parts, the splits you agree and your messages. Your legal name, PRO and IPI are asked for at the point you agree a split, because a split sheet that cannot name its writers cannot get them paid. You can use Blend without them until then; you cannot agree a split without them.

Because we have a legitimate interest (Article 6(1)(f)) in keeping a published split sheet and its record of who agreed and when, which other writers rely on if a share is ever disputed, and in keeping Blend secure. You can object to this; see “Your other rights”.

We do not use your data for advertising, we do not sell it, and no decision with legal or similar effect about you is made automatically. No AI model reads your recordings, lyrics or messages: tempo and key are measured inside your own browser.

Blend is for people aged 18 and over, and we do not knowingly hold data about anyone younger.

Who handles it for us

Supabase stores the database, the sign-in system and the files you upload, on servers in London. It processes your data only on our instructions.

Nothing is loaded from any other company when you use Blend: no analytics, no advertising, no tracking pixels, and the typefaces are served by Blend itself.

What is stored on your device

Only what Blend needs to work, so we do not ask you to accept cookies: the sign-in cookies that keep you signed in, one note that you have already seen the opening animation in this visit, and a copy of the app's own files so it opens quickly. None of it tracks you across other websites.

Getting a copy

Settings → Your data → Download everything. It arrives as a JSON file: your profile, every song you are on, your parts, both sides of every conversation, and your shortlist. Audio is listed by name rather than embedded, because a single vocal take would make the file too large to open — you can download each recording from the song it belongs to.

Deleting your account

Settings → Your data → Delete my account. You are shown exactly what will happen before you confirm, item by item.

Everything that identifies you is destroyed, including your legal name, PRO and IPI number, and including on songs that are already published. The email address and password you sign in with go last, so the account can never be signed in to again. Pictures and recordings you uploaded go too, unless a song that stays still plays them.

One thing survives, and you should know why. If you are credited on a song whose split sheet is already published, that sheet is frozen and other writers have signed it. Removing your row would either leave a share belonging to nobody or quietly change what everyone else agreed to. So the row stays and reads as “Former contributor”. The share is still yours to claim through your PRO — we simply stop holding who you are. We rely on UK GDPR Article 17(3) for this, which allows retention where it is necessary for legal claims.

Audio you contributed to a published song stays for the same reason: it is part of a finished record that other people own a share of.

Your other rights

You can correct anything wrong with your profile from Settings at any time. The download above is in a machine-readable format, so you can take it to another service. You can object to how we use your data, ask us to restrict it, and complain to the Information Commissioner’s Office (ico.org.uk) if you think we have got it wrong. You do not have to go through us first.

Still to be settled

Some things on this page need answers before Blend takes real accounts, and are deliberately not guessed at here: who the named data controller is and the address to contact them at; how long we keep data after an account closes, stated in calendar terms; what happens if data is ever processed outside the UK; and the names of the company that will host the public website and the one that will send Blend's emails, once chosen. This notice will be updated with those answers before launch, not after.
