Terms of Service

These Terms of Service constitute a legally binding agreement made between you, whether personally or on behalf of an entity ("you") and Ball Engine Studios ("we", "us", or "our"). Ball Engine Studios operates ballengine.app as a website and brand entity. This agreement concerns your access to and use of our website (ballengine.app) and the Creator Studio simulation software (collectively, the "Site").

To access certain features, you must register for an account. You represent that all registration information is accurate. You are solely responsible for maintaining the confidentiality of your account credentials, passwords, and multi-factor authentication (MFA) details. We utilize security validations (such as Cloudflare Turnstile) to safeguard account portals against unauthorized automated access.

Age Eligibility: You must be at least 16 years old to create an account, or older where your jurisdiction sets a higher age for consenting to data processing. You must be at least 18 years old, and legally able to enter a contract, to purchase any paid plan or make any other payment to us. If you are under 18, you may use the free plan only. We do not direct the Services to children, and we do not knowingly collect personal information from anyone under 16.

Critical Music & MIDI Upload Notice

You retain ownership of all content you upload to the Site. However, you are solely responsible for all content you upload, including but not limited to copyrighted songs, MIDI files, audio clips, and custom presets.

You explicitly represent and warrant that you own or have obtained all necessary licenses, rights, and permissions to use any media uploaded to or processed through Creator Studio. BallEngine does not pre-screen or verify the ownership of uploaded content. We do not routinely review, monitor, or pre-screen user uploads for copyright ownership. However, we reserve the right to investigate, restrict, or remove any content where we are required to do so by law or where we reasonably believe infringement has occurred.

Exported Content Responsibility

Rendering or exporting a video using a song through our Site does NOT grant you redistribution rights for that music. You are solely responsible for compliance with copyright laws before publishing rendered content on social media (e.g. TikTok, YouTube Shorts).

Exporting a video from BallEngine does not remove or alter any copyright protection attached to uploaded music. Rendered videos may still be identified, claimed, muted, or taken down by automated rights-detection systems such as YouTube Content ID, TikTok's copyright detection, Instagram or Facebook Rights Manager, or similar systems operated by third-party platforms.

BallEngine is a creation tool. We provide software for building and rendering physics-based videos. BallEngine is not a music streaming service, a music distribution platform, or a public audio hosting service, and we do not obtain synchronization licenses, master recording licenses, mechanical licenses, or any other music rights on your behalf.

License grant. You retain ownership of everything you upload. Because we cannot store, render, or export your files without your permission, by uploading any content you grant BallEngine a worldwide, non-exclusive, royalty-free, revocable, limited license to store, reproduce, process, synchronize, transcode, and render that content solely for the purpose of providing the Services you request. This license automatically terminates when the content is deleted from our systems, except where continued retention is required by law or by routine backup procedures.

Temporary & cached copies. To provide the Services, BallEngine may create temporary or cached copies of uploaded files during rendering, transcoding, synchronization, waveform analysis, preview generation, and export. These copies are created solely to deliver the functionality you request and are not used for any other purpose.

No AI training. We do not use your uploaded audio, MIDI files, project configurations, or exported videos to train generalized machine-learning or AI models without your explicit consent.

AI-assisted composition. The studio can write original instrumental music for you. A language model produces only a short plan (key, tempo, chord progression, song form and a melodic motif); every note is then written locally by our own composition engine. The result is original music generated for you, and you may use it commercially in the videos you make here, subject to your plan. These tools generate instrumental music and text suggestions only. They do not clone voices, synthesise any real person, swap faces, produce deepfakes, or reproduce existing recordings, and you may not attempt to use them for any of those purposes.

Ball Engine Studios (operating as ballengine.app) respects intellectual property rights and expects its users to do the same. We respond to notices of alleged copyright infringement that comply with the Digital Millennium Copyright Act ("DMCA").

If you believe your copyrighted work is being infringed on our site, please send a written takedown notice to our compliance team. To learn about notice requirements, designated agents, and our repeat infringer policies, please consult our detailed DMCA Policy.

In accordance with the DMCA and standard platform practice, we may suspend or permanently terminate the accounts of users who are repeat copyright infringers.

BallEngine acts as a private creator workspace, not a public media platform. Uploaded files remain private to your account: they are never publicly indexed, never made searchable, and are accessible only by the account owner unless you intentionally choose to share a simulation showcase link. Sharing such a link is entirely at your discretion.

While we provide cloud storage (via Cloudflare R2) for convenience, we do not guarantee storage permanence. Users are responsible for maintaining their own backups. Deleted or corrupted projects may not be recoverable. Inactive projects (no logins for 18 months) may be moved to archival storage or deleted after extended periods.

When you create an account with Analytics cookies allowed, you agree that we may link the visitor journey record kept in your browser to your account and continue recording how you use our website and Studio until your first payment, or for up to 7 days from your first visit, whichever comes first. This record covers which pages you view, how far you scroll and which controls you press. It never includes anything you type, your content or your payment details.

We use this record only to improve BallEngine and our checkout. We keep it for 180 days after recording stops and delete it when you delete your account. Section 3b of our Privacy Policy explains it in full.

We also collect usage, device and render performance data, and use fraud prevention signals such as IP address, device and payment card identifiers, as described in our Privacy Policy.

• Render times are estimated and not guaranteed.
• Export failures may occur due to simulation complexity.
• Resolution availability depends on subscription tier.
• Cloud rendering queue priorities are subject to load balancing.
• We reserve the right to modify or remove specific rendering filters.

Paid plans are sold through a merchant of record, which is the seller of record for your purchase. Our primary provider is Polar; Dodo Payments is used as an alternative on some checkouts. Whichever one processed your subscription is the party that invoices you, holds the tax obligation for the sale, appears on your card or bank statement, and handles billing queries and refunds. Your receipt names the provider that handled your purchase.

Paid subscriptions are subject to auto-renewal at the end of each billing cycle (monthly or annually) unless cancelled. You can manage or cancel your subscription at any time from your authenticated Account Settings, or through the billing portal of the merchant of record that sold it, which your receipt identifies.

Render credits are prepaid and expire 12 months after purchase; unused credits lapse at that point. Credits included with a plan expire at the end of the billing month they belong to. Cloud renders made without an active Creator, Pro, Elite or Agency plan carry the ballengine.app watermark.

You agree not to use the Services to distribute unauthorized copyrighted media, reverse engineer rendering models, scrape creator projects, inject malware, or exploit WebGL simulations.

To view the exhaustive list of prohibited system behaviors, user abuse policies, and hardware/IP level ban enforcements, please read our full Acceptable Use Policy.

View Acceptable Use Policy

Some features place national flags, country names and other real-world symbols in your videos. They are provided for entertainment and to tell simulated objects apart. The outcome of a simulation is decided by physics and a random seed and is not a statement, ranking, prediction or opinion about any country, people, government, religion or culture. Ball Engine Studios does not endorse or take any position on them.

Ball Engine Studios is not affiliated with, sponsored by or endorsed by any government, national team or sporting body. The flags in the Services are our own simplified drawings and are not official emblems.

You agree not to use these features, or any video made with them, to promote hatred, violence, discrimination or hostility against any nation, people or group; to depict, predict or comment on a real war, conflict, attack or disaster; to insult, degrade or show the destruction of any national flag or symbol; or to suggest that any government or national body endorses you. Section 2 of the Acceptable Use Policy sets out these rules in full and forms part of these Terms.

Many countries protect their flag and national symbols by law. You are solely responsible for every title, caption, description and publication you make with these features, and for complying with the laws of every country where you create, publish or show your videos. Section 8b (Indemnification) applies to any claim, fine or loss arising from them.

We may change, limit or withdraw any flag feature or country at any time, without notice.

If we believe these rules have been broken, we may remove or refuse to render content, turn off features for your account, suspend or terminate your account without refund under section 8, and cooperate with the platforms involved and with lawful requests from authorities.

We reserve the right to suspend or terminate your account and block access to the Services, at our sole discretion, without warning or liability, if:

• You violate these Terms of Service or our Acceptable Use Policy.
• You infringe on third-party intellectual property or copyright laws via uploaded audio/MIDI files.
• A payment failure occurs and remains unresolved through successive dunning retry windows.
• You engage in fraudulent activity, scripting exploits, or system load attacks.

You agree to defend, indemnify, and hold harmless Ball Engine Studios (operating as BallEngine / ballengine.app), together with its owners, operators, employees, officers, affiliates, and partners, from and against any claims, demands, damages, liabilities, losses, costs, or expenses (including reasonable legal fees) arising out of or related to (a) content you upload, process, render, or export through the Services; (b) your violation of these Terms of Service or any applicable law; or (c) your infringement of the intellectual property or other rights of any third party.

BALL ENGINE STUDIOS (OPERATING BALLENGINE.APP) IS NOT LIABLE FOR REVENUE LOSSES RESULTING FROM RENDER DELAYS, UPLOAD DISPUTES, OR COPYRIGHT STRIKES ON EXPORTED CONTENT.

THIS AGREEMENT IS GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF INDIA, WITHOUT REGARD TO CONFLICT-OF-LAW PRINCIPLES. NOTHING IN THIS AGREEMENT LIMITS ANY NON-WAIVABLE RIGHT YOU HAVE UNDER THE CONSUMER LAW OF YOUR OWN COUNTRY OF RESIDENCE. COPYRIGHT CLAIMS WILL BE RESOLVED VIA OUR DMCA POLICY.
