These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "you," or "your") and Rex ("Rex," "we," "us," or "our") governing your access to and use of the Rex iOS application and related services (collectively, the "Service"). By accessing or using the Service in any manner, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference.

IMPORTANT — PLEASE READ CAREFULLY. THE FOLLOWING SECTION LIMITS OUR LIABILITY TO YOU.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, REX AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS PROVIDE THE SERVICE "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. WITHOUT LIMITING THE FOREGOING, WE EXPLICITLY DISCLAIM ANY WARRANTIES OF:
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.
IMPORTANT — PLEASE READ CAREFULLY.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL REX, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, OR LICENSORS BE LIABLE FOR ANY:
IN ALL CASES, REX'S TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING UNDER OR RELATED TO THESE TERMS OR YOUR USE OF THE SERVICE SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL AMOUNT YOU PAID TO REX IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE CLAIM, OR (B) FIFTY U.S. DOLLARS ($50.00).
THE LIMITATIONS IN THIS SECTION APPLY WHETHER THE LIABILITY ARISES IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHERWISE, AND EVEN IF REX HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. SOME JURISDICTIONS DO NOT ALLOW LIMITATION OF LIABILITY FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES, SO THE ABOVE LIMITATION MAY NOT APPLY TO YOU.
You agree to defend, indemnify, and hold harmless Rex and its officers, directors, employees, and agents from and against any and all claims, damages, obligations, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from or related to:
Rex reserves the right to assume the exclusive defense and control of any matter subject to indemnification by you, in which case you agree to cooperate with our defense of such claim.
PLEASE READ THIS SECTION CAREFULLY — IT MAY SIGNIFICANTLY AFFECT YOUR LEGAL RIGHTS.
In the event of any dispute, controversy, or claim arising out of or relating to these Terms or the Service ("Dispute"), you and Rex agree to first attempt to resolve the Dispute informally by contacting us at rexstudyapp@gmail.com. We will try to resolve the Dispute within 30 days of receiving your notice.
If the Dispute is not resolved informally, you and Rex agree to submit the Dispute to binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. The arbitration will take place in Texas, or by telephone or video conference. The arbitrator's decision shall be final and binding and may be entered as a judgment in any court of competent jurisdiction.
Notwithstanding the above, either party may seek injunctive or other equitable relief in a court of competent jurisdiction to prevent actual or threatened infringement, misappropriation, or violation of intellectual property rights.
Consumers outside the United States: the arbitration requirement and Texas venue in this Section do not apply to you if the mandatory consumer-protection laws of your country of residence prohibit them. In that case, you may bring claims in the courts of, and under the laws of, your country of residence, and nothing in these Terms removes any non-waivable right or remedy available to you as a consumer under your local law.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOU AND REX AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. If a court finds that this class action waiver is unenforceable for any reason, then the arbitration agreement in Section 15 shall not apply to that Dispute, which shall instead be litigated in a court of competent jurisdiction.
These Terms are governed by and construed in accordance with the laws of the State of Texas, United States, without regard to its conflict-of-law provisions. For disputes not subject to arbitration, you agree to submit to the exclusive jurisdiction of the state and federal courts located in Texas.
Mandatory local law prevails. If you are a consumer, this choice of law and venue does not deprive you of the protection of any mandatory provisions of the law of the country in which you reside. Where you live in the EEA, the United Kingdom, or another jurisdiction whose consumer-protection laws grant you stronger or non-waivable rights, those rights and the courts of your home country remain available to you regardless of the Texas designation above. Rex makes the Service available worldwide and intends these Terms to apply only to the extent permitted by the local law applicable to you.
You may stop using Rex at any time. You can permanently delete your account and all associated data directly in the App at Settings → Delete Account; this action cannot be undone. You may also request deletion by contacting us at rexstudyapp@gmail.com.
We may suspend or terminate your access to the Service at any time, with or without notice, for any reason, including but not limited to: violation of these Terms; conduct that we believe is harmful to other users, Rex, or third parties; or requests from law enforcement or government authorities.
Upon termination: your license to use Rex immediately ends; you must cease all use of the App; we may delete your account and User Content. Sections 9 (Intellectual Property), 12 (Disclaimers), 13 (Limitation of Liability), 14 (Indemnification), 15 (Dispute Resolution), 16 (Class Action Waiver), and 21 (General Provisions) survive termination.
The following terms apply to your use of Rex downloaded from the Apple App Store:
The Service may be subject to U.S. export control laws and regulations. You agree to comply with all applicable export and re-export control laws and regulations. You represent that you are not located in a country that is subject to a U.S. Government embargo and that you are not on any U.S. Government list of prohibited parties.
