These Terms of Use ("Terms") govern your access to and use of the Drum Machine mobile application (the "App"). By downloading, accessing, or using the App, you agree to these Terms.
Drum Machine ("Drum Machine," "we," "us," or "our") provides a mobile application for rhythm practice, accompaniment playback, and related music utility features.
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to use the App for your personal, lawful use on devices you own or control, in accordance with these Terms and Apple's platform rules.
You agree not to:
use the App in violation of applicable law or regulation
copy, distribute, sell, lease, or commercially exploit the App except as expressly permitted by us or applicable law
reverse engineer, decompile, disassemble, or attempt to extract source code from the App except where such restriction is prohibited by law

The App currently provides features such as rhythm playback, MIDI or drum content playback, sound or playback preference controls, and premium content unlocking through Apple in-app purchases.
Features may change over time. We may add, modify, suspend, or remove features without prior notice, to the extent permitted by applicable law.
Some features or content may require a paid purchase, such as:
monthly subscription access
yearly subscription access
lifetime unlock access
All purchases inside the iOS App are processed by Apple through the App Store and StoreKit.
Payment will be charged to your Apple ID account when you confirm the purchase.
Auto-renewable subscriptions renew automatically unless canceled at least 24 hours before the end of the current billing period.
Your account may be charged for renewal within 24 hours before the end of the current billing period.
You can manage or cancel subscriptions through your Apple account settings.
Lifetime access, where offered, is a one-time purchase and does not auto-renew.
We do not control Apple's billing systems and are not responsible for delays, billing issues, or payment processing errors caused by Apple or your payment provider.
Refunds, billing disputes, and purchase management for App Store transactions are generally handled by Apple under Apple's policies. If you want to request a refund for an App Store purchase, you should use Apple's official purchase support channels.
The App, including its design, text, graphics, audio resources, rhythm data, MIDI-related content, branding, and software, is owned by us or our licensors and is protected by applicable intellectual property laws.
These Terms do not transfer any ownership rights to you except for the limited license expressly granted above.
If the App allows you to interact with external sharing tools or system interfaces, you remain responsible for the content you choose to share and for your use of any third-party platform or service.
Your use of the App is also subject to our Privacy Policy. Please review it together with these Terms.
We do not guarantee that the App will always be available, uninterrupted, error-free, or compatible with every device or operating system version.
We may release updates, bug fixes, changes to content, or feature adjustments at any time. Some features may stop working properly if you do not install available updates.
The App is provided on an "as is" and "as available" basis to the maximum extent permitted by applicable law. We disclaim all warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement.
We do not guarantee that:
the App will be uninterrupted or error-free
the App will always meet your expectations or requirements
defects will always be corrected immediately
To the maximum extent permitted by applicable law, we will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, goodwill, or business opportunity arising out of or related to your use of the App.
To the maximum extent permitted by applicable law, our total liability for claims relating to the App will not exceed the amount you paid, if any, for the App or relevant purchase giving rise to the claim.
We may suspend or terminate your access to the App or certain features if we reasonably believe you have violated these Terms or if we need to do so for legal, technical, or operational reasons.
You may stop using the App at any time by uninstalling it.
We may update these Terms from time to time. When we do, we will update the "Last updated" date above. Continued use of the App after updated Terms become effective means you accept the revised Terms, to the extent permitted by applicable law.
