Privacy policy · last updated 8 November 2026
NULTAKT also runs on a Mac with Apple silicon, under the same policy: where the text says iPad, read Mac.
In one sentence
NULTAKT sends nothing on its own, has no accounts or analytics, and neither sells nor shares data. Everything you do stays on your iPad. Only if you send a diagnostic report yourself, by email and after seeing what it carries, does that report reach the developer.
What data it collects
None on its own. There is no account, no analytics, no advertising, no tracking and no developer server. The app asks for no permission for the microphone, camera, location or contacts. Only if you turn on Ableton Link does iOS ask you for local network access (section 3). The one exception is the diagnostic report that you decide to send (section 8).
Internet and local network
NULTAKT does not connect to the internet on its own and has no servers of its own. The only thing that talks to the internet is Apple's purchase system, when the app checks your purchase or when you buy or restore the full version (see “Buying the full version”). Only if you turn on Ableton Link does it use the local network (Wi-Fi or cable) to find other devices with Link and sync the tempo with them: it sends no personal data and nothing leaves your network. The Ableton library that does this is included in the app; as long as you don't turn Link on, NULTAKT does not touch the network.
What is stored on your device
Your projects, memories and “orders” (saved sets of memories), and the app's preferences (chosen screen, settings). They are stored only in the app's own storage, visible to you in the Files app, and are removed when you delete NULTAKT. A saved project includes the name of the MIDI device you assigned to each track. In addition, NULTAKT keeps a technical record of the most recent activity, 4 MiB at most (between one and several days of use, depending on how much you use it): clock stalls, warnings, which machine was playing, which control was touched and to what value, the random seeds, the tempo, the model of any known MIDI devices, the state of the iPad (memory, temperature, battery), and the pitch and channel of notes that kept sounding too long. This record does not hold your music, the names of your projects or tracks, or the name of your iPad. Separately, so that a problem can be reproduced note by note, NULTAKT keeps a copy of your project at the start of each session and the changes you make afterwards (8 MiB at most; those from earlier sessions are deleted on their own after 24 hours). That copy does hold your music and the names you gave things, and it leaves the iPad only if you send a report with INCLUDE MY PROJECT turned on. The record, that copy and the crash diagnostics that iOS hands to the app (1.5 MiB at most) stay on the iPad, outside backups, and are removed when you delete NULTAKT. Your iPad backups (iCloud or your computer) belong to Apple and you manage them in the iPad Settings.
MIDI
NULTAKT sends MIDI notes and clock to the devices and apps you choose, and creates a virtual MIDI port called “NULTAKT Out”. In this version it receives no MIDI from anything.
Audio
NULTAKT neither records nor listens to sound. It keeps an audio session running only so the iPad does not suspend the app and MIDI keeps playing with the screen off. That session makes no sound, except the metronome click if you turn on the speaker metronome.
What leaves your iPad
Only what you export or share yourself (a project, a memory, an “order”) through the system share sheet, to the destination you choose: NULTAKT neither sees nor copies it. And, if you decide so, the diagnostic report in section 8.
Diagnostic report
In MENU › ABOUT › SEND REPORT you can send the developer a technical report of how NULTAKT has behaved on your iPad. Nothing is sent on its own: first you see what it carries, then you open the system mail and send it yourself. NULTAKT has no server or connection of its own to send it. The report carries your iPad model and its iPadOS version, the NULTAKT version, the recent technical record (section 4) and the crash diagnostics that iOS hands to the app. It is compressed and sealed so that it stays small and cannot be read at a glance; what you see in that window is a summary of its contents. If you turn on INCLUDE MY PROJECT, it also carries the open project and the copy NULTAKT keeps at the start of each session with the changes made afterwards (section 4), with your music, the names you gave things and the names and identifiers of your MIDI devices. With them the problem can be reproduced note by note. Because it arrives by email, the developer sees the address you send it from, so it is data linked to you. It is used only to find and fix the problem; it is not shared with anyone or used for advertising or tracking. It is kept until the problem is closed and, at most, 12 months; the attached project and its session copies are deleted when the problem is closed, and you can ask for them to be deleted sooner by writing to [email protected].
Apple
If you install NULTAKT from the App Store or TestFlight, Apple may collect information under its own policy. The developer only receives aggregate statistics from Apple and, if you allowed it in the iPad Settings, crash reports; never your projects. These are Apple's reports, separate from the one you can send yourself (section 8).
Buying the full version
The app is free, and a single in-app purchase unlocks the full version. Apple handles the purchase and its restoration: the developer receives neither your payment details nor who you are, only the aggregate sales figures Apple provides in App Store Connect. NULTAKT uses no server of its own to validate the purchase: the iPad itself checks it with StoreKit 2's local verification (Apple's signature), which can also work without a connection. Whether you have the full version is saved only on your iPad, among the app's preferences, and is erased when you delete NULTAKT; each time the app opens it asks Apple again, and RESTORE PURCHASES recovers it.
Free trial
Without the full version, NULTAKT works as a trial: 20 minutes from the moment the app opens, each time it opens, running straight through whether or not the transport is playing, and in the background too. The time used is counted only in the app's memory: it is not saved on the iPad, not sent anywhere, and starts from zero again at every launch.
Children
NULTAKT collects no data on its own, from children either. The diagnostic report exists only if someone decides to send it, from their own email.
Changes
If NULTAKT ever connects to the internet on its own, collects data or adds another network feature (for example network MIDI), this policy will be updated first and the app will say so. Last reviewed: 8 November 2026.
