FM-1 Hub for iPhone · Last updated 2 November 2026

FM-1 Hub does not collect personal data. It has no account, no analytics, no advertising and no tracking. Its developer runs no server, so nothing is sent to the developer.

What stays on your iPhone

The app keeps these in its own folder on your phone:

• –your settings;
• –firmware packages it downloaded or installed;
• –your backups: the firmware package and, for firmwares that offer it, the music archive;
• –the install history.

You can see them in the Files app under On My iPhone › FM-1 Hub, copy them elsewhere, or delete them. Deleting the app deletes them too.

What the app downloads

To show the catalogue and install firmware, the app downloads files from:

• –The FM-1 Firmware Hub (thefirmwarehub.com): the firmware list, its pictures and the firmware packages. A package can also come from another address the list gives for it, such as its maker's GitHub releases.
• –GitHub (api.github.com): when a backup looks for a firmware's package in its maker's releases.
• –M-VAVE's download server (on Alibaba Cloud, in Hong Kong): the official firmware and its release notes.

The app sends no personal data with these requests. As with any website, each server sees your IP address and which file was asked for. Each of these services has its own privacy policy.

Your FM-1

The app talks to your FM-1 over the USB cable. Firmware and music archives go only between your iPhone and the synth.

Links and sharing

Links you tap open in your browser. When you share a backup's files, they go only where you choose to send them.

Source code

The app's complete source code is public, so all of this can be checked: github.com/debreczi/fm1firmwarehost
