Privacy

The app

• No MiO server holds your music. It is downloaded straight from the service to your device. This website has a server behind it; the app does not use it.
• There is no advertising identifier, no device fingerprinting and no third-party analytics or crash-reporting software in the app.
• Uninstalling MiO removes everything it stored, because everything it stored was on your phone.
• Copying your library to another phone writes a file to a folder you choose. It lists what is in your library — titles and links, not the audio — and it goes nowhere except where you put it. The other phone downloads its own copies.

What the app contacts by itself

Two things, each time you open it:

• Expo (u.expo.dev) — checks whether a fix is available. It receives your app’s version, not anything about you.
• Cloudflare (pub-6eb86219220840aa84b5dd9ecde0059c.r2.dev and dl.dlany.uk) — reads a small file listing the newest release. It is a plain request for a public file.
• GitHub (raw.githubusercontent.com) — the same file, asked for only if the first request fails. GitHub is unreachable from some countries, which is why there are two.

Like any request over the internet, these tell Expo, Cloudflare and GitHub the internet address you are connecting from. None of them is sent anything that identifies you as a MiO user, and none is told what is in your library.

What the app contacts when you ask it to

Only in response to something you do, and only for the feature you used: YouTube, Bilibili, NetEase Cloud Music, QQ Music, Kugou when you search, add a link or import a playlist; and Spotify if you connect a Spotify account to import from it.

Those services receive your request and your internet address, and their own privacy policies apply to what they do with it. MiO does not send them anything about you beyond what the request itself requires.

The donate buttons open Ko-fi (ko-fi.com) or Afdian (afdian.com) in your browser. MiO has no payment system of its own: it opens a link, sends them nothing about you, and is never told whether you gave anything.

Diagnostics

MiO keeps a short record of what it has been doing — imports, playback and requests that failed — on your phone. It is not uploaded. The one exception is if you have pointed MiO at a server you run yourself, in which case it is sent there once a day, and nowhere else.

It deliberately contains no song titles, no artists and no links. If you use Copy report or Share, that record leaves your device only because you pressed the button, and only to wherever you choose to send it.

This website

These pages (mio.dlany.uk) are served through Cloudflare, which sits between you and the server. Cloudflare therefore sees requests for this site, including the internet address they come from, and keeps its own logs of them. The server behind it keeps ordinary access logs for security and troubleshooting.

There are no cookies, no trackers and no advertising on these pages. The download page remembers your language choice in your own browser; that never leaves your device.

The problem-report form

If you report a problem, the form is hosted by Tally and your answers are stored there. It asks what went wrong and for the diagnostics report. An email address is optional and is used only to reply to you about that report — never for anything else, and never shared.

This is the only place MiO asks you for personal information.

Your rights

Because the app stores nothing about you, there is generally nothing to request, correct or delete. The exception is a report you have sent through the form: you can ask for it to be deleted, and it will be.

To ask about anything on this page, use the report form.

Changes
