By accessing and using SuperTime Ultra, you accept and agree to be bound by the terms and provision of this agreement.
Permission is granted to use this application for personal, educational, or professional musical practice. You may not:
Free practice tools remain available without an account. To create or access an optional free web account, verify your email with the sign-in link we send you. You can choose to copy saved polyrhythm rhythms to your account and load those copies on another signed-in device. Device saves and rehearsal audio remain local unless you explicitly use a sharing or account-saving feature.
Email practice tips and product updates require a separate opt-in. Signing in does not subscribe you, and declining or withdrawing that choice does not affect your account or access to the free tools. Use the unsubscribe link in a news email to stop future news emails.
When available for purchase, Pro on the web is EUR29 once for the web rehearsal-pack workflow. It does not include Pro on iPhone. The total shown at Stripe Checkout is the amount you authorize. Your verified receipt email recovers web access on another browser. Saved workspaces remain on the device where you saved them unless you choose to copy supported rhythms to your account; a purchase does not automatically upload your workspaces or rehearsal audio.
Existing verified lifetime Supporter Pass purchases retain access to this web workflow. If access or delivery fails, use the purchase-recovery form or contact dnncha@gmail.com with your receipt for help or a refund request. Do not buy again to retry a failed download. Basic playback, public sharing and individual exports remain free.

Timing is scheduled with the Web Audio API, but output and responsiveness vary by device, browser, operating system, and audio route. The tool is provided "as is" without warranty of any kind.
In no event shall SuperTime Ultra or its suppliers be liable for any damages (including, without limitation, damages for loss of data or profit, or due to business interruption) arising out of the use or inability to use the materials on this website.
