Privacy

How CS/M handles information in the apps, the browser versions, this website and the beta. The sections below say what the apps do with sound and motion, all of it on your device; what this site and the beta keep; and what reaches Apple.

  1. 01Nothing collectedMatter / Field and Polite Disorder, on iPhone, iPad and the Mac, and as plug-ins, collect no personal data and nothing about how you use them. There’s no account, no sign-in, no advertising and no tracking.
  2. 02Nothing sentThe apps and plug-ins never connect to the internet. Everything they need is inside them: the interface, the sounds, the studies and the kits. SHARE makes a link to the study or kit you’re on. If you’ve changed its sound, the link carries your settings too, after a # at its end, a part of a link that browsers never send to a website. The link holds the sound and nothing about you, and goes only where you send it. On an iPhone or iPad with the app, the device checks a small file on this site, through Apple, to know the app opens those links; the app itself still sends nothing.
  3. 03What you makeYour scenes and projects, the audio you load and the 3D models and scans you bring in stay on your device, or wherever you save them: in the Files app, or in your music app’s project when you use a plug-in. On a Mac, when you drag a hit out of Polite Disorder, it first saves the hit in its own Dragged out folder (in your Library, under Application Support), so your music app can keep finding it. It stays on your Mac until you delete it. Each app also keeps its settings, and the scene or project it was last on, on your device, so it opens where you left off.
  4. 04Head trackingIf you turn on Head tracking in an app, it uses motion data from supported headphones, such as AirPods Pro, to keep sounds in place as you turn your head. It’s used on your device as it arrives, and never kept or sent. Your device asks you first, and you can turn it off in its Privacy & Security settings.
  5. 05Tilt to pourIf you turn on Tilt in Matter / Field, or TILT in Polite Disorder, on an iPhone or iPad, the app reads how the device is tipped from its motion sensors, to pour the sound that way. It’s used on your device as it arrives, and never kept or sent. In your browser on a phone or tablet, Polite Disorder’s TILT works the same way, after your browser asks.
  6. 06MicrophoneMatter / Field and Polite Disorder use your microphone or audio interface only when you ask them to. In Matter / Field, press RECORD where you load a sound, or turn on LIVE INPUT, which makes its sound from what it hears as you play. In Polite Disorder, press RECORD in a voice’s sound, at + ADD A LAYER, REPLACE or LOAD SAMPLE. What they hear is used on your device as it arrives. A recording is saved only if you press USE THIS, and live input only if you press Keep. Either way it becomes part of your scene or project, and it’s never sent. Your device asks you first, and you can turn it off in its Privacy & Security settings.
  7. 07Crash reportsIf you choose in your device’s settings to share analytics with app developers, Apple may pass on the apps’ crash reports. That’s Apple’s service, and yours to turn on or off. When you test a beta through TestFlight, Apple and Complex State Machines (CS/M) receive its crash logs, usage information and any feedback you send, as TestFlight tells you when you join.
  8. 08This websiteThis site counts its visits with Vercel Web Analytics, which sets no cookies and keeps nothing in your browser. For each page you open, it notes the page, the site that sent you, roughly where you are (country, region and city) and what you’re using (the kind of device, its system and its browser). To count a visit once rather than at every page, it makes a short code from your browser’s request and throws it away within a day. Your IP address isn’t stored, and none of it follows you to other sites. The lighter versions of the apps that play in your browser here collect nothing either: what you load and make stays on your device, nothing is uploaded, and nothing is kept in your browser after you leave. Besides the beta’s list and the codes, below, nothing is collected here. Nothing here follows you across sites, so the site works the same whether or not your browser asks sites not to track you.
  9. 09The beta’s listIf you join the TestFlight list on the beta page, the site keeps your email address, your name if you give one, the apps you chose, when you joined and when you were added as a tester, in its private storage at Vercel. They’re kept only to add you as a tester in TestFlight, and given to no one but Apple, which emails you the invite. The services we use to run the site and its email handle them for us, and only for that. When you join, and when you come off the list, an email saying so goes to the company’s own inbox, beta@complexstatemachines.com. To come off the list, press Take me off under the form, or write to that address. You stay on the list until you come off it. It’s for people 13 and older, as the Terms say; if a child under 13 has joined, write to us and we’ll take them off. Your IP address isn’t kept. To limit how often the form can be sent, each day’s attempts are counted under a short code that many addresses share, not the address itself. To slow down guessing on the beta page, wrong passwords from one connection are counted for ten minutes, in memory, then forgotten.
  10. 10CodesIf you have a code for the browser versions, the site checks it when you type it in. Each code is kept with the name it was made for, the apps it opens, when it was made, how many times it’s been used and when it was last used. Nothing about your device is kept. To slow down guessing, wrong codes from one connection are counted for ten minutes, in memory, then forgotten. A code is kept until it’s deleted.
  11. 11Your informationYou can ask to see what the site keeps about you, take a copy, have it corrected or have it deleted. Write to csm@complexstatemachines.com and we’ll answer within a month. The beta’s list keeps you because you asked to join it; the visit counter runs because a site needs to know how it’s used. If you’re in the EU or the UK and think we’ve got something wrong, you can also complain to your data protection authority.
  12. 12Who we areComplex State Machines, LLC (CS/M), formed in Montana, makes the apps and runs this site. Write to csm@complexstatemachines.com. Help with the apps is on Support.
