LOSESTREAK IS NOT A MEDICAL, HEALTH, WELLNESS, DIETARY, OR THERAPEUTIC APPLICATION.
You expressly acknowledge and agree that:

NEVER DISREGARD PROFESSIONAL MEDICAL ADVICE OR DELAY SEEKING TREATMENT BASED ON ANYTHING IN THIS APP.
5. AI-Generated Content
The App uses artificial intelligence (Claude by Anthropic) to generate content including:

- Progress photo comparisons: Visual commentary on Day 1 vs final day photos
You acknowledge and agree that:
- AI-generated content may be inaccurate, incomplete, or erroneous
- Calorie estimates can vary significantly from actual nutritional content
- AI verdicts are for entertainment — they do not constitute professional fitness, health, or dietary advice
- The competitive/sarcastic tone of verdicts is intentional and not meant to cause harm
- AI does not have medical training and cannot assess your health status
- You should not rely solely on AI-generated content for any important decisions

22. Binding Arbitration & Class Action Waiver
PLEASE READ THIS SECTION CAREFULLY — IT AFFECTS YOUR LEGAL RIGHTS.
22.1 Agreement to Arbitrate
You and LoseStreak agree that any dispute, claim, or controversy arising out of or relating to these Terms or the App ("Disputes") will be resolved by binding individual arbitration, rather than in court, except that:
- Either party may bring an individual action in small claims court if the claim qualifies
- Either party may seek injunctive or other equitable relief in court to prevent infringement of intellectual property rights
22.2 Waiver of Jury Trial
YOU AND LOSESTREAK WAIVE THE RIGHT TO A TRIAL BY JURY.
22.3 Class Action Waiver
YOU AND LOSESTREAK AGREE THAT DISPUTES WILL BE RESOLVED ONLY ON AN INDIVIDUAL BASIS AND NOT AS A CLASS ACTION, COLLECTIVE ACTION, PRIVATE ATTORNEY GENERAL ACTION, OR ANY OTHER REPRESENTATIVE PROCEEDING.
If a court or arbitrator determines that this class action waiver is unenforceable, the entire arbitration agreement shall be void and the dispute shall proceed in court.
22.4 Arbitration Rules
Arbitration will be administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules, as modified by this section. The AAA Rules are available at www.adr.org.
- The arbitrator shall have exclusive authority to resolve all Disputes, including arbitrability
- The arbitration shall be conducted in English
- The arbitration may be conducted by telephone, online, or based on written submissions, as selected by the party initiating the arbitration
- The arbitrator's decision shall be final and binding
- Judgment on the award may be entered in any court of competent jurisdiction
22.5 Arbitration Costs
Payment of arbitration fees will be governed by the AAA's Consumer Arbitration Rules. If your claim is for $10,000 or less, we will pay all arbitration fees. If your claim is for more than $10,000, filing fees and arbitrator fees will be split per AAA Rules.
22.6 Informal Resolution First
Before initiating arbitration, you must first contact us at [email protected] and attempt to resolve the dispute informally for at least 60 days.
22.7 Opt-Out Right
You may opt out of this arbitration agreement by sending written notice to [email protected] within 30 days of first accepting these Terms.

If you opt out, you and LoseStreak will resolve disputes in court as set forth in Section 21.
22.8 Future Changes to Arbitration
If we make changes to this arbitration section (other than changes to our contact information), you may reject the changes by sending written notice within 30 days of the change. If you reject changes, the most recent version of the arbitration agreement you accepted will apply.

Our failure to enforce any right or provision of these Terms will not be considered a waiver of that right or provision. Any waiver must be in writing and signed by us.
23.4 Assignment
You may not assign or transfer these Terms or your rights hereunder without our prior written consent. We may assign these Terms without restriction. These Terms bind and inure to the benefit of each party's successors and permitted assigns.

These Terms do not create any third-party beneficiary rights, except that Apple Inc. and its subsidiaries are third-party beneficiaries of these Terms with respect to Apple's App Store requirements. Apple has the right to enforce these Terms against you.
23.6 Force Majeure
We will not be liable for any delay or failure to perform resulting from causes outside our reasonable control, including acts of God, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, epidemics, pandemics, strikes, or failures of third-party services.
23.7 Export Compliance
You agree to comply with all applicable export laws and regulations. You represent that you are not located in a country subject to a U.S. government embargo or designated as a "terrorist supporting" country, and you are not listed on any U.S. government list of prohibited or restricted parties.
23.8 U.S. Government Users
The App is a "commercial item" as defined in 48 C.F.R. 2.101, consisting of "commercial computer software" and "commercial computer software documentation." If acquired by a U.S. government agency, the government's rights are limited to those set forth in these Terms, per 48 C.F.R. 12.212 and 48 C.F.R. 227.7202.
