Welcome to TierBreak. These Terms of Service ("Terms") govern your use of the TierBreak iOS app and the tierbreak.app website (together, the "Service"). By creating an account or using the Service you agree to these Terms.
An adult sets up the family account. Signing yourself up requires you to be 13 or older, and the sign-up asks for your date of birth before anything else. Nobody under 13 can create an account on their own.
The account holder can then invite a player to their own sign-in, at any age. The player gets their own email and password and sees only their own training and matches. For a player under 13 this is the guardian's decision: we ask for their agreement, tell them plainly what their child will and will not be able to do, and record that they said yes. They can withdraw it at any time, which turns the player's sign-in off. A player under 13 is never asked their age by us; the guardian has already told us.
What a player under 13 cannot do. The AI features never run for them, with or without a guardian's permission. Their journal and written reflections are not private from their guardian, and they are told so when they write. These rules follow the player, so they apply the same whether the guardian is using the app or the child is.
The account holder is responsible for the account, for the players in it, and for the activity under any sign-in they invite.
You are responsible for the account you create and for any activity under it. Keep your credentials private. We can suspend or terminate accounts that violate these Terms, that abuse the Service, or that we are required to suspend by law. You can delete your account at any time from Settings; deletion is prompt and permanent.
Training logs, match data, mental-game and wellness notes, scouting notes, goals, and other content you enter remain yours. You grant TierBreak the limited rights needed to store, process, and display that content back to you (and to people you have invited into your family) so the Service can work.
We do not sell your content, and we do not use it for advertising.
The Service itself belongs to TierBreak: the app and its code, the mental performance curriculum and its worksheets, the guided-audio sessions, the training methodology and evidence metrics, and the TierBreak name and design. While you have an account, we license this to you for your family's personal, non-commercial use.
Please don't copy, redistribute, resell, or publicly republish our content, and don't use it to build a competing product or service. This license ends when your account does; your own content (above) remains yours regardless.
We build TierBreak with our families, and we love hearing ideas. If you send us suggestions or feedback, you agree we can use them to improve the Service without owing you compensation or attribution. This applies to ideas about the product; your personal data and your family's content are always governed by the privacy policy, never by this paragraph.
Don't use the Service to break the law, to harass another person, to scrape or reverse-engineer the Service, to attempt to gain access to data that isn't yours, or to upload content that infringes someone else's rights. Don't share an account with anyone you wouldn't invite into your family in the app.
Player ratings and related figures in TierBreak are primarily entered by your family (for example, a World Tennis Number or UTR you type in) and are for your reference. Where official data from bodies such as USTA, ITF, or World Tennis Number becomes available, it arrives only through official, consented channels. We don't warrant the accuracy, freshness, or completeness of third-party data, and those third parties may change or remove their data at any time.
TierBreak is in active development. Features may change, data may occasionally be reset during beta phases (with notice), and you may encounter bugs. Use the Service at your own discretion and back up anything that matters to you outside the app.
The Service is provided "as is" and "as available," without warranties of any kind, express or implied. TierBreak is a training and tracking tool; it is not medical, psychological, legal, or financial advice, and it is not a substitute for a coach, trainer, or healthcare professional.
To the maximum extent permitted by law, TierBreak is not liable for indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or opportunity arising out of your use of the Service.
To the same extent, our total aggregate liability for all claims relating to the Service is limited to the greater of fifty US dollars ($50) or the amounts you paid TierBreak in the twelve months before the claim arose. Nothing in these Terms limits liability that cannot be limited by law, including for fraud or for death or personal injury caused by negligence.
You are responsible for claims, losses, and costs that arise from your violation of these Terms, your violation of the law, or content you submit that infringes someone else's rights, and you agree to reimburse TierBreak for reasonable costs (including attorneys' fees) that result.
We may update these Terms from time to time. If we make a meaningful change we'll update the date above and surface a notice in the app on next launch. Continued use after the change takes effect means you accept the updated Terms.
If we ever decide to discontinue TierBreak, we commit to the following, so your family's record is never trapped and never lingers:
This commitment survives any change to these Terms other than one that strengthens it. It is also described on our Trust page.
If any part of these Terms is found unenforceable, the rest remains in effect. These Terms (with the privacy policy) are the entire agreement between you and TierBreak about the Service. If we don't enforce a provision right away, we haven't waived it. We aren't responsible for delays or failures caused by events beyond our reasonable control. Your account and any subscription are personal to your family and can't be sold or transferred; we may assign these Terms as part of a merger, acquisition, or sale of the business, provided your rights under them are not materially reduced.
These Terms are governed by the laws of the Commonwealth of Pennsylvania and applicable United States federal law, without regard to conflict-of-law principles. TierBreak LLC is organized in Pennsylvania, USA.
