Unison is a journal of the music you listen to. It needs to know a few things about you to be that, and it does not want to know anything else. This page says exactly what is collected and what happens to it, in plain terms rather than by listing every category of data that exists.

Unison is made and operated by 10xS Devs, S.A. de C.V., which is responsible for the personal data described here. You can reach a real person at jose.lopez@10xsdevs.com.

What Unison stores

• Your account. An email address and a password, handled by Supabase Auth. The password is never stored in a form anybody — including us — can read.
• Your profile. The display name, handle, bio and location you type in. All of it is optional except the handle, and all of it is visible to other members.
• What you log. The records you log, when you heard them, your ratings, your reviews and the notes you write. This is the point of the app.
• What you do with other people. Who you follow, lists you make or join, likes and replies, club membership and votes, and direct messages.
• A device token, if you turn on push notifications, so Apple can deliver them. It is deleted when you sign out or turn notifications off.
• On this website, one cookie — only if you pick a language with the switch. It holds the word en or es and nothing else, so the site keeps showing you that language; it is sent nowhere but here, and it expires after a year.

What Unison does not do

• No advertising, and no advertising identifiers. Unison does not carry ads and has no reason to know who you are anywhere else.
• No tracking across apps or websites. Nothing here follows you anywhere.
• No selling or sharing your data with anyone, for any purpose.
• No analytics SDKs. There is no third-party code in the app watching what you tap.
• Unison does count a few things about itself. How many people have joined, how much is being logged and rated — and, so we can tell whether Discover's recommendations are any good: which albums Discover put in front of you, which shelves you scrolled to, which of those records you opened, and when you pressed Listen — and, when a new version introduces itself, which of the lines on that card you tapped. Each of those is held as the record — and the shelf, where that matters — and the day. Not the time, not how long you looked, not where you scrolled to, and never more than one row a day however many times you look. They stay in Unison, they are deleted with your account, and nobody can look at them and see a person: the only view of them is a count.
• No listening history from your streaming service. Unison never plays music and is not connected to your Spotify, Apple Music or any other account. The Listen button opens a link, and that is the whole extent of it. What you have heard is what you told Unison you heard.

Who can see what you write

You decide, and the rules are enforced by the database rather than by the app, so no version of Unison can show somebody something you told it to hide. Your journal has two separate settings — who can see the records you log, and who can see the notes you write about them — and each can be private, limited to followers, or public. Reviews and lists have their own visibility. Messages are only possible between two people who follow each other.

Reading a review in another language. If somebody who is allowed to see your review uses Unison in the other language, they can ask for a translation. When they do, the text of that review — and nothing else — is sent to DeepL to be translated. DeepL deletes it as soon as it has answered and does not use it to train anything; Unison keeps the translation so the same words are not sent twice. Private reviews are never sent anywhere. You can switch this off for your reviews in Settings.

Where it lives

On Supabase, which hosts the database and handles authentication. Album and artist information comes from MusicBrainz and Cover Art Archive, both open datasets; artist photographs come from Wikimedia Commons. Push notifications go through Apple. Translations of reviews, when a reader asks for one, go through DeepL. Nobody else receives your data — except DeepL, for the one review being translated, as described above.

Deleting your account

In the app: Profile → Settings → Account → Delete account. It is immediate and permanent. Your journal, ratings, reviews, lists, queues, messages and club membership are deleted with it. Records you added to somebody else's shared list stay on that list, with your name removed — the list belongs to the person who made it.

Children

Unison is not directed at children under 13 and does not knowingly collect anything from them.

Changes, and how to reach us

If this page changes in a way that matters, the app will say so rather than quietly updating a date. Questions, or a request to see or remove what is held about you: jose.lopez@10xsdevs.com.
