Terms of Service

Effective September 29, 2026 · Last updated September 29, 2026

1. Eligibility

You must be at least 13 years old to use the Service. You must be at least 18 years old, and able to form a binding contract, to buy a sponsorship. If you buy a sponsorship for a business or other organization, you confirm that you are authorized to accept these Terms on its behalf, and “you” includes that organization.

2. Playing ProTennis

ProTennis is a free browser game. No account is needed to play. We grant you a personal, non-exclusive, non-transferable, revocable license to access and play the game for your own non-commercial entertainment, subject to these Terms. You may stream or record your gameplay and share it, including on monetized channels, as long as you don’t suggest we endorse you.

3. Acceptable use

You agree not to:

• use a player name, display name or logo that is offensive, hateful, harassing, sexually explicit, impersonates someone, or infringes anyone’s rights;
• cheat, use bots or scripts, exploit bugs, or tamper with game data or network traffic to gain an unfair advantage or disrupt other players;
• attack, overload, probe or scan the Service, bypass rate limits or security measures, or access it by automated means other than as a normal browser;
• copy, modify, reverse engineer, resell or create derivative works of the Service, except where the law expressly allows it;
• use the Service for anything unlawful, fraudulent or harmful, or to pay with a payment method you are not authorized to use.

4. Sponsorships

The ProTennis stadium has ten sponsor spots (six court boxes and four screens). You can bid to place your display name, logo and optional website link (your “Sponsor Content”) on a spot. By bidding, you agree to these rules:

1. Separate running bids. Each spot has its own bids. Your bid on a spot is the total of all your successful payments for that spot (your “Total”).
2. The top Total is shown. The Sponsor Content of the bidder with the highest Total on a spot is displayed on that spot in the game. On equal Totals, the bidder who reached that Total first keeps the spot.
3. Minimums. An empty spot opens at a minimum amount, and a new bid must beat the current top Total by at least a minimum raise. The current minimums and the exact amount you will pay are shown before you pay and are checked again when you submit.
4. Raising. If you already have a Total on a spot, you pay only the difference to raise it.
5. No time limit. Your Sponsor Content is displayed for as long as yours is the top Total on that spot, subject to these Terms.
6. Replacement. A higher Total by someone else replaces your Sponsor Content immediately. Your Total remains on the spot and does not expire, so you can retake the spot later by paying only the difference.
7. Timing. If another bid is confirmed while you are paying, your payment is still added to your Total, but it may no longer be the top Total. Your confirmation email tells you whether your bid leads.
8. Going live. Your Sponsor Content goes live once your payment is confirmed. Some payment methods take longer to confirm than others.

What a sponsorship is, and isn’t. A sponsorship is a paid, non-exclusive advertising placement inside a video game. It is not an investment, a financial product, gambling, a prize, a share in the game or an ownership interest in any spot, and your Total has no cash value and cannot be transferred, withdrawn or exchanged. We do not guarantee any number of players, views, impressions, clicks or other results, that a spot will be visible in every match, camera angle or device, or that your Sponsor Content will be displayed without interruption. We may move, resize or restyle spots when we update the stadium, and we will try to keep each spot comparably visible. We may change bidding rules, minimums or prices for bids placed after the change; changes never reduce a Total you have already paid.

5. Payments, taxes and refunds

• Payments are processed by Stripe, Inc. on a secure Stripe-hosted page, and are subject to Stripe’s terms. We do not see or store your full card details.
• Prices are in the currency shown at checkout (currently US dollars). You authorize us, through Stripe, to charge the amount shown to your selected payment method. Your bank may charge its own fees, such as for currency conversion.
• You are responsible for any taxes that apply to your purchase, other than taxes on our income. If we are required to collect tax, it will be shown at checkout.
• Sponsorship payments are final and non-refundable, except as described in our Refund Policy. Being replaced by a higher bid is not a reason for a refund.
• If a payment is reversed, charged back or refunded, we will reduce your Total by that amount, which may remove your Sponsor Content from the spot. Please contact us before disputing a charge with your bank; we can usually resolve problems faster.

6. Sponsor content

Your promises

By submitting Sponsor Content, you confirm that:

• you own it or have all rights, licenses and permissions needed to use it and to grant us the license below;
• it, and any website it links to, does not infringe or misappropriate anyone’s copyright, trademark, privacy, publicity or other rights;
• it is truthful and not misleading, and doesn’t impersonate or falsely imply an affiliation with any person, brand or organization;
• it complies with all applicable laws, including advertising and consumer protection laws.

What’s not allowed

Sponsor Content, and the website it links to, must not contain or promote:

• hate speech, harassment, threats, violence, or discrimination against any group;
• sexually explicit or adult content;
• illegal products or services, weapons, illegal or recreational drugs, tobacco or vaping products;
• gambling, betting, or cryptocurrency, token or investment schemes;
• malware, phishing, scams, or deceptive or misleading claims;
• political or issue-based advertising;
• anything unsuitable for a general audience that includes teenagers.

License to us

You keep ownership of your Sponsor Content. You grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, resize, format and display it in the Service, including in the game, on the sponsorship screen and in screenshots, trailers, videos and promotional material showing the game, for as long as your Total exists on the spot and for a reasonable time afterwards for material already created. Players may also capture it in their own recordings and streams.

Review and removal

Your Sponsor Content goes live without prior manual review. We may review it at any time and may remove, hide or refuse any Sponsor Content, or reject a bid, that we reasonably believe breaks these Terms, infringes someone’s rights, or exposes us or our users to harm or legal risk. If we remove Sponsor Content for breaking these Terms, no refund is owed. To report Sponsor Content, including an intellectual property complaint, email [email protected]. A sponsorship is not an endorsement: we do not endorse and are not responsible for sponsors, their products or their websites.

7. Our intellectual property

The Service, including its software, game design, characters, artwork, audio, text and the ProTennis name and logo, is owned by us or our licensors and protected by intellectual property laws. Some 3D character models are used under open licenses. Except for the limited license in section 2, these Terms don’t give you any rights in the Service. If you send us feedback or suggestions, we may use them without any obligation to you.

8. Changes to the Service

We may change, update, suspend or discontinue any part of the Service, including game features and sponsor spots. If we permanently discontinue the game or the sponsorship feature, we will give sponsors whose content is live at least 30 days’ notice by email. Refunds in that case are governed by our Refund Policy.

9. Suspension and termination

We may suspend or end your access to the Service, remove your Sponsor Content, or cancel your bids if you materially or repeatedly breach these Terms, if we are required to by law, or to protect the Service or its users. You may stop using the Service at any time. Sections 5, 6 (License to us, for material already created), 7 and 10 through 15 survive termination.

10. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE OR SECURE, OR THAT ANY STATISTICS OR ACTIVITY FIGURES SHOWN ON THE SITE REFLECT ACTUAL USAGE. Some jurisdictions don’t allow certain disclaimers, so some of these may not apply to you.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, RYTHAM SEQUENCE LLC AND ITS MEMBERS, MANAGERS, EMPLOYEES AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, DATA OR BUSINESS OPPORTUNITY, ARISING FROM OR RELATED TO THE SERVICE OR THESE TERMS, EVEN IF ADVISED OF THEIR POSSIBILITY. OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM AND (B) US $100. These limits do not apply to liability that cannot be limited by law, such as for fraud or gross negligence.

12. Indemnity

You will defend, indemnify and hold harmless Rytham Sequence LLC and its members, managers, employees and agents from any third-party claims, losses, liabilities and expenses (including reasonable attorneys’ fees) arising from your Sponsor Content, the website it links to, your breach of these Terms, or your violation of any law or third-party right.

13. Governing law and disputes

These Terms are governed by the laws of the State of Wyoming, USA, without regard to its conflict-of-laws rules. Before filing a claim, you agree to try to resolve the dispute informally by emailing [email protected], and we will try to resolve it with you within 60 days. If it isn’t resolved, any claim must be brought exclusively in the state or federal courts located in Wyoming, and both parties consent to their personal jurisdiction, except that either party may bring an individual claim in small-claims court where it qualifies. If you are a consumer living outside the United States, you may also have the benefit of mandatory consumer-protection laws and courts of your country of residence, and nothing in these Terms takes those rights away.

14. General

• Changes to these Terms. We may update these Terms. We will change the “Last updated” date and, for material changes, notify sponsors by email at least 14 days in advance. Changes don’t apply retroactively to bids already placed. Continuing to use the Service after changes take effect means you accept them.
• Entire agreement. These Terms, the Privacy Policy and the Refund Policy are the entire agreement between you and us about the Service.
• Severability and waiver. If any provision is found unenforceable, the rest remains in effect. Not enforcing a provision is not a waiver of it.
• Assignment. You may not transfer your rights under these Terms without our consent. We may assign them in connection with a merger, acquisition or sale of assets.
• Force majeure. We are not responsible for delays or failures caused by events beyond our reasonable control, including outages of hosting, network or payment providers.
• Notices. We may send notices to the email address you verified. You can send notices to [email protected].
