Terms of Use

Effective 12 November 2026.

The agreement

Tennis Rivals is licensed to you under Apple's Licensed Application End User License Agreement (the "Standard EULA"). These Terms of Use add the rules of the game. If the two ever conflict about your rights to use the app, the Standard EULA wins. The app is provided by Mark Sinistaj ("we", "us"), not by Apple. By playing, you accept both. Our Privacy Policy explains how data is handled.

Who can play

Anyone can play Tennis Rivals. If you are under the age of majority where you live, a parent or guardian should agree to these terms for you and can manage purchases and online play with Apple's Screen Time and Ask to Buy. Online features need a Game Center account and are subject to Apple's Media Services Terms.

Virtual items, Credits and purchases

• A licence, not property. Cosmetic items (outfits, hair, sunglasses, headwear, racket finishes, ball trails, celebrations, walk-ons, nameplates, titles), season passes and Credits are part of the game. We grant you a personal, non-transferable licence to use them in Tennis Rivals. They have no cash value, cannot be sold, traded, transferred or exchanged for money or anything outside the game, and we never buy them back.
• Credits are earned by playing and spent on in-game items. They are never sold, are never part of a paid product, and cannot be bought with real money. Paid items are never sold for Credits.
• Nothing changes a match. Every player has the same body, speed and racket. Items are cosmetic. The whole career, every venue and surface, practice, the Daily Drill and the Rivals Open are free.
• Prices. Every price is shown in your local currency by the App Store, including any tax Apple charges. There is no premium currency, no loot box and no random reward for money: you see exactly what you get before you buy.
• What you buy is yours to keep. Purchases are one-time and never renew. Season passes never expire. Products are never time-limited and stay on sale. We set prices in US dollars; Apple sets the local price in each country and may adjust it for exchange rates and taxes. When we lower a price on a published date, we never raise it again.
• Restoring and devices. Purchases belong to your Apple Account. Settings › Purchases › Restore purchases brings them back on any device signed in to that account. Credits and earned progress are saved on the device; we cannot restore them if they are lost (keep a device backup).
• Refunds are handled by Apple at reportaproblem.apple.com, under Apple's rules and your local consumer law. If a purchase is refunded, its items are removed from your locker; nothing else is taken away.
• Mistakes. If a bug gives you an item or Credits by mistake, we may correct it. If a bug takes away something you paid for or earned, tell us and we will restore it.
• Family Sharing is not available for Tennis Rivals purchases.

Fair play

Tennis Rivals is a game of pure skill and only works if everyone plays fair. You must not:

• use cheats, modified apps, scripts, macros, emulated touches or any automation to play for you;
• tamper with the app, its saved data, its timing or its network messages, or exploit bugs to win, gain items or harm other players (please report bugs instead);
• disconnect on purpose, stall, or arrange results with another player;
• play on someone else's account to raise its trophies or scores or rating, or use several accounts to get around a pause from ranked play;
• reverse engineer, extract or interfere with the app or our services, except where the law allows it regardless of these terms.

How we enforce it. Ranked matches are played through our server, which keeps a record of each match and decides its result. When both apps report the same result, it stands. When a player leaves or stops responding, the server's own record decides. When the two apps disagree, the result is held until it has been checked. An app that is shown to have broken the rules of a match gets a strike; two strikes within 90 days pause ranked play for that player for 30 days. Not joining matches that were found for you pauses your ranked search for a short time. We may also void results, correct a rating, or remove leaderboard entries and prizes won unfairly. All of this applies to ranked play only: friendly online matches, practice, the Tour and your items always stay available.

You can ask us to review any decision by writing to support@tennisrivals.app within 30 days; we answer within 14 days.

Online play

• Online matches run through Apple's Game Center (ranked matches: through our own server). We cannot guarantee that an opponent is available, that a connection stays up, or that online features are offered in every country.
• Ranked matches are found and played through our own server, which decides each result and keeps the ratings and the ranked leaderboard (see the Privacy Policy). If the server cannot be reached, the app looks for a ranked opponent through Game Center instead.
• Computer opponents. If no one is found quickly, you may play a computer opponent at your level. A ranked match that the server did not see (against a computer opponent, or played while the server could not be reached) is recorded as such: it moves your rating less than a match played through the server, only a limited number of times a day and not at all in the top tiers, and it can never by itself put you on the ranked leaderboard.
• Ratings and ranks are for matchmaking and for fun: nothing is sold for them, and what ranked play earns (Credits and the cosmetic rewards of a season) has no cash value and cannot be bought, sold or exchanged. Your rating belongs to your Game Center account and follows it to any device. The first time the app reaches the server, the rating on your device is carried over once; the server limits how high a carried rating can start. We may correct or recalculate ratings and ranks, for example to fix a bug or to undo unfair results.
• If one player leaves or stops responding, or the connection fails, the result follows the rules shown in the app (for example, the player who left loses).
• Quick reactions are preset messages only, and you can mute them.
• From your opponent's player card, during or after a match, you can mute or block them. Blocking hides their name and reactions on your device, declines their rematch offers and invitations, and the app will not pair you with them again. You can also report them to us from the same card.

Rivals Open: official rules

• Organiser. The weekly Rivals Open is organised by Mark Sinistaj. Apple is not a sponsor of, and is not involved in, the Rivals Open or any other Tennis Rivals event in any way.
• Free. No purchase or payment is needed to enter or win, and buying anything does not improve your chances.
• When. Each Open runs for one week, from Monday 00:00 to Sunday 23:59:59 UTC. Each week has one court type and one draw of seven labelled bots, the same for every player in the world.
• Who and how. The Open opens to every player who has reached Tour 3 on the free Tour Path. Start a run from the Rivals Open screen and play round by round until you lose or win the final. You may start as many runs as you like; your best run of the week counts.
• Score. 1,000 points for each round won, plus 10 points for each point of winning margin in the matches you won, plus 2,000 points for winning the title. Scores go to the weekly Game Center leaderboard, which needs a Game Center account; without one you can still play the Open for its in-game rewards.
• Prizes. Only in-game items with no cash value: the week's champion cup in your trophy cabinet and, the first time you win, the "Open Champion" title and nameplate frame; a finalist badge; and cabinet plates for finishing in the top 1% or top 10% of the week. Prizes cannot be exchanged, transferred or paid out.
• Fair play. We may remove scores, runs and prizes that break the fair-play rules above. Our decision on the standings is final, subject to the review described there.

Names and conduct

In online matches and on Game Center leaderboards, other players see your Game Center nickname. You set it in Apple's Game Center under Apple's rules, and we cannot change it. The player name you choose in Tennis Rivals is shown only on your own device. Names must not be offensive, hateful or sexual, impersonate someone else, or include contact details or links. In ranked matches played through our server and on the ranked leaderboard, other players see a nickname the game makes up for you instead of your Game Center nickname. If you meet an offensive name, block the player to hide it on your device, and report it to us. Be a good sport: no harassment of other players.

Our game and its assets

Tennis Rivals, its name, logo, characters, venues, code, art, music and sounds are owned by us or licensed to us by the creators listed in Credits & Licences. Third-party assets are licensed only for use inside Tennis Rivals: you may not extract, copy, redistribute or reuse them, or use them to train any artificial intelligence model. You may share screenshots and videos of your own play for non-commercial purposes. Tennis Rivals is an independent game and is not affiliated with any tennis tour, event, governing body or player.

Changes and availability

We keep improving Tennis Rivals, so features, items, balance and these terms can change. We will post updated terms here with a new date before they apply; if a change is significant, we will also announce it on the home page of this website and in the App Store release notes of the next version. If you keep playing after a change, the new terms apply; if you do not agree, you can stop using the app. We will not take away items you bought because of a change. If we ever have to stop online play, we will announce it on this website and on the App Store product page at least 60 days ahead, and offline play and your items will keep working on your device as far as Apple's platform allows.

Warranty and liability

We make Tennis Rivals with care but provide it "as is": we do not promise that it will always be available or free of bugs. To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability to you is limited to the amount you paid for Tennis Rivals purchases in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, or your statutory rights as a consumer (including, in the EU and UK, your rights for digital content that is faulty or not as described).

Law and disputes

These terms are governed by the law of United States, without affecting the mandatory consumer protections of the country where you live; you may also bring a claim in the courts where you live. Please contact us first; most problems can be solved by e-mail.
