Legal
Terms of Use
Last updated 19 October 2026
These terms cover the Oxidzr Sequencer app and its AUv3 plugin for iPad and iPhone (together, "the app") and this website, oxidzr.app. They're made by Andrei Nevar ("we"). By using them you agree to these terms.
The app licence
The app is licensed to you, not sold, through the App Store. Your licence is governed by Apple's Licensed Application End User License Agreement (the standard EULA), together with these terms. If the two disagree, Apple's EULA applies.
Trial and purchase
- The app is free to download and fully usable for a 14-day trial from the first time it opens.
- After the trial, the sequencers stop until you buy the one-time in-app purchase "Unlock Oxidzr". There's no subscription. Your projects stay on your device either way.
- The purchase is made through Apple's App Store under Apple's terms, and unlocks both the app and its AUv3 plugin. Use Restore purchase to unlock it again on another device or after reinstalling, with the same Apple Account.
- Refunds are handled by Apple, through reportaproblem.apple.com.
Using the app
- You may use the app for any music you make, personal or commercial. What you create with it is yours.
- Don't copy, modify, reverse-engineer or redistribute the app, except where the law allows it regardless of these terms.
- Don't use the app or this website to break the law or to harm others.
MIDI and your equipment
The app sends MIDI to the apps and devices you choose. You're responsible for how your instruments and equipment respond to it, including volume levels. Take care with your hearing and your gear.
Help
The built-in Help writes answers with an on-device language model. Answers are drawn from the guide but can occasionally be wrong; the guide on this website is the reference.
Third parties
Ableton Link is a trademark of Ableton AG, and Apple, iPad, iPhone, iPadOS, App Store and Apple Intelligence are trademarks of Apple Inc. Other names belong to their owners. Their use here doesn't imply endorsement.
Updates
We may update the app to add features, fix problems or change how things work, and may stop offering it. Updates are delivered through the App Store.
No warranty
The app and this website are provided "as is", without warranties of any kind, to the extent the law allows. We don't promise that they'll be free of errors or always available. Back up anything important.
Liability
To the extent the law allows, we aren't liable for indirect or consequential losses, or for loss of data, arising from your use of the app or this website. Nothing in these terms limits liability that can't be limited by law, or your rights as a consumer.
Changes to these terms
We may update these terms. The current version is always posted here, with the date above.
Law
These terms are governed by the law of the Netherlands, without affecting any mandatory protection you have under the law where you live.
