CourtFlow terms of use

Effective September 5, 2026

The short version

CourtFlow is a basketball play designer published by NesFlow6. You may use it to design plays for your own coaching. CourtFlow Pro is an auto-renewing annual subscription billed by whichever app store you downloaded from, and you cancel it there. The plays you make are yours, and we never receive them. The optional AI feature uses an API key you supply and bill yourself.

The sections below are the full agreement. Please read them.

Who this agreement is with

These terms are a binding agreement between you and Cody Neslen, doing business as NesFlow6 ("NesFlow6", "we", "us"), covering the CourtFlow mobile app and any updates to it. By downloading, installing, or using CourtFlow you agree to these terms. If you do not agree, do not use the app.

If you are using CourtFlow on behalf of a school, club, or organization, you confirm you are authorized to accept these terms for that organization.

License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use CourtFlow on devices you own or control, for coaching purposes — your own coaching, and coaching the teams you work with.

CourtFlow, its design, and its code remain ours. This license does not transfer ownership of anything.

What you may not do

• Redistribute, resell, rent, lease, sublicense, or otherwise make the app available to anyone else as a product.
• Copy, modify, or create derivative works of the app.
• Reverse engineer, decompile, or disassemble the app, except to the extent that applicable law expressly permits it despite this restriction.
• Work around, disable, or tamper with the checks that separate free features from CourtFlow Pro features.
• Use the app in violation of any law, or in violation of the rules of the app store you downloaded it from.

Designing plays for the teams you coach and sharing your own exported PDFs and videos with your players and staff is normal use, not redistribution. What you may not do is hand out the app itself.

Free and Pro

CourtFlow is free to download and use, with limits:

• Free — create and save up to 5 plays, and export any play as a PDF.
• CourtFlow Pro — unlimited plays, video export, and the experimental AI play generator.

We may change what each tier includes. If a change would remove something material from the tier you are paying for, we will give reasonable notice first, and you can cancel before your next renewal.

CourtFlow Pro subscription

CourtFlow Pro is an auto-renewing annual subscription (product identifier com.nesflow6.courtflow.pro.annual). It is sold through the app store you downloaded CourtFlow from, and that store — not NesFlow6 — bills you.

• Payment is charged to your Apple ID if you downloaded from the App Store, or to your Google Play account if you downloaded from Google Play, at confirmation of purchase.
• It renews automatically for another year unless you cancel at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours prior to the end of the current period.
• To manage or cancel: on iPhone and iPad, Settings → Apple ID → Subscriptions. On Android, Google Play → Payments & subscriptions → Subscriptions.
• Canceling stops the next renewal. Pro stays active until the end of the period you have already paid for. We do not prorate a partial period.
• Deleting the app does not cancel your subscription. Cancel in the store, as above.

The current price is shown in the app and in the store listing before you confirm the purchase; it is set per storefront and can change. Any free trial or introductory offer is described at the point of purchase, and any unused portion of a free trial is forfeited when you buy a subscription.

Refunds are handled by the store you bought from, under that store's policy — Apple's for App Store purchases, Google's for Google Play purchases. We cannot issue, reverse, or override a store's billing decision. If something has gone wrong, email us anyway at support@nesflow6.com and we will help where we can.

Your plays are yours

You own the plays, notes, and exports you create in CourtFlow. We claim no rights in them, and we never receive them — CourtFlow has no servers and no accounts. You are responsible for what you create and for keeping your own copies of anything you would not want to lose. See the CourtFlow privacy policy for exactly what is stored and where.

The optional AI feature

CourtFlow Pro includes an experimental AI play generator. It is off unless you turn it on, and it works only if you supply your own API key from a provider you choose — either xAI (Grok) or Anthropic (Claude).

• The request is yours, not ours. The text you write goes directly from your device to the provider you selected, using your API key and your account with that provider. It does not pass through any NesFlow6 server — we do not run one.
• Your agreement is with the provider. Your use of that provider is governed by their terms and their privacy policy. NesFlow6 is not a party to it, and we cannot act on your behalf with them.
• You pay for your own usage. Every request billed to your API key is your cost. We do not see, control, meter, or cap what you spend, and we do not reimburse it. Set your own limits with your provider.
• Output is not guaranteed. Generated plays come from a third-party model. They can be wrong, illegal under your league's rules, unsuitable for your players, or simply bad basketball. Review anything it produces before you coach it. We are not responsible for the output or for any decision made on the basis of it.
• The feature depends on someone else. A provider can change its models, pricing, availability, or terms at any time, which may degrade or break this feature. That is outside our control, and it is not a defect in CourtFlow.

If you never turn the feature on, none of the above applies to you.

No warranty

CourtFlow is provided "as is" and "as available", without warranties of any kind. To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty that the app will be uninterrupted, error-free, or that it will preserve your data.

CourtFlow is a diagramming tool. It is not coaching advice, medical advice, or a safety system, and nothing it produces should be treated as any of those.

Some jurisdictions do not allow the exclusion of certain warranties, so parts of this section may not apply to you.

Limitation of liability

To the fullest extent permitted by law, NesFlow6 will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost data, lost plays, lost profits, or lost opportunity, arising out of or relating to your use of CourtFlow — even if we have been advised that such damages are possible.

Our total liability for all claims relating to CourtFlow is limited to the greater of the amount you paid us or the app store for CourtFlow in the twelve months before the claim, or twenty-five US dollars ($25).

Some jurisdictions do not allow these limitations, so parts of this section may not apply to you.

Termination

You may end this agreement at any time by deleting CourtFlow from your devices. Remember that deleting the app does not cancel a subscription — cancel that in your app store.

We may suspend or end your license if you materially breach these terms, most obviously by tampering with the app or redistributing it. If we end your license and you had time remaining on a paid subscription, you may request a refund of the unused portion from the store you purchased from.

The sections on your plays, no warranty, limitation of liability, and governing law survive the end of this agreement.

If you downloaded CourtFlow from the App Store

These terms are between you and NesFlow6, not Apple, and NesFlow6 alone is responsible for CourtFlow and its content. Apple has no obligation to provide any maintenance or support for CourtFlow. If CourtFlow fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price; to the maximum extent permitted by law, Apple has no other warranty obligation for CourtFlow. NesFlow6, not Apple, is responsible for addressing any claim relating to CourtFlow, including product liability claims, claims that it fails to conform to a legal requirement, and claims that it infringes someone's intellectual property rights. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

You also confirm that you are not located in a country subject to a US Government embargo or designated as a terrorist-supporting country, and that you are not on any US Government list of prohibited or restricted parties.

Changes to these terms

We may update these terms. The current version always lives at this URL with its effective date at the top. If a change is material, we will give reasonable notice — in the app, or on this page ahead of the date it takes effect. Continuing to use CourtFlow after a change takes effect means you accept the updated terms; if you do not, stop using the app and cancel any subscription before its next renewal.

Governing law and disputes

These terms are governed by the laws of the State of California, without regard to its conflict-of-law rules.

Please email us first. If you have a problem, write to support@nesflow6.com with a description of it. Most things are settled that way, and we ask that you give us 30 days to try before starting formal proceedings.

If that does not resolve it, any dispute will be brought exclusively in the state or federal courts located in San Diego County, California, and you and NesFlow6 consent to the jurisdiction of those courts. Nothing here prevents either of us from seeking relief in a small claims court, or from asking a court to stop infringement of intellectual property.

Miscellaneous

These terms, together with the CourtFlow privacy policy, are the entire agreement between us about CourtFlow. If any part is found unenforceable, the rest stays in force. Our not enforcing a provision is not a waiver of it. You may not transfer this agreement; we may transfer it as part of a sale or reorganization of the business.
