Privacy Policy
Effective 4 November 2026 · Last updated 4 November 2026
DXcompanion collects no personal data. It has no accounts, no analytics, no advertising and no tracking, and it doesn't send anything to the developer. Your voices stay on your devices and, if you use iCloud, in your own private iCloud storage.
Who we are
DXcompanion for iPad and Mac (“the app”) is developed by Marian Fujara (“I”, “me”). This policy covers the app and this website. Questions go to marian.fujara@gmail.com.
Data the app collects
None. The app has no servers of its own and contains no analytics, crash-reporting, advertising or tracking code. It doesn't ask for your name, email address, location or contacts.
Data stored on your device
- Your User Library: the voices you save, with their names, tags and favourites.
- Settings: which MIDI ports and channel to use, and display choices such as whether the keyboard is shown. They're kept in the app's own preferences on the device.
- Files you open or export (.syx and JSON) go only where you choose to put them.
iCloud
If you're signed in to iCloud, the app syncs your User Library between your devices through Apple's CloudKit, in the private database of your own Apple Account. Only you can read it; I can't see or access it. Apple handles this data under the Apple Privacy Policy. To stop syncing, turn off iCloud for DXcompanion in your device's settings.
Bluetooth
The app uses Bluetooth only to connect to Bluetooth MIDI adapters, such as the Yamaha MD-BT01, that link it to your reface DX. It doesn't scan for, record or share any other Bluetooth devices.
MIDI
The app exchanges MIDI messages (voices, parameter changes and notes) with the instruments connected to your device. These messages stay between your device and your instrument. The MIDI log in the settings is kept in memory and cleared when the app quits.
This website
This site sets no cookies and runs no analytics. It's served by Cloudflare Pages, which, like any web host, may process technical data such as IP addresses to deliver the pages and protect against abuse, under Cloudflare's privacy policy.
Children
The app collects no data from anyone, including children under 13.
Your rights
Because I hold no data about you, there's nothing for me to show, correct or delete. You can delete your voices in the app, and remove its iCloud data in your device's iCloud settings under Manage Storage.
Changes
If this policy changes, the new version will be posted here with a new date. If the app ever starts handling data differently, the policy will change before the app does.
