US-2. Eligibility

  1. You must be at least 18 years old to create an account or use the Service.
  2. You may not use the Service if you are barred from receiving services under the laws of the United States or any other applicable jurisdiction, including if you are located in a country or region subject to comprehensive U.S. sanctions, or you are on a U.S. government list of prohibited or restricted parties.
  3. If we learn that a member who lives in the United States is under 18, we may suspend or delete the account.

US-3. Health and Safety

  1. The Service is a social platform for sharing your running life. It is not a medical device and does not provide medical, health, or training advice. Distance, pace, heart rate, calories, and other figures shown in the Service (including figures imported from a health app or a watch) may be inaccurate.
  2. Running and other physical activity involve risk of injury. Consult a doctor before starting or changing an exercise program, and stop if you feel pain, dizziness, or shortness of breath.
  3. You are responsible for your own safety, including obeying traffic laws and being aware of your surroundings. Do not use the Service in a way that distracts you while running.

US-4. Copyright Complaints (DMCA)

  1. We respect intellectual property rights and respond to notices of alleged copyright infringement that comply with the U.S. Digital Millennium Copyright Act ("DMCA").
  2. If you believe content on the Service infringes your copyright, send a written notice to our designated agent that includes:
  3. Designated agent: LEE SEUNGHWAN (Tididi), email tididiapp@gmail.com (subject line "DMCA Notice"). The agent's full contact information, including mailing address and telephone number, is posted at https://tididi-db733.web.app/dmca-en.html and is registered in the U.S. Copyright Office's DMCA Designated Agent Directory.
  4. If your content was removed because of a DMCA notice and you believe it was removed by mistake or misidentification, you may send a counter-notice to the designated agent that includes: your physical or electronic signature; identification of the removed material and where it appeared; a statement under penalty of perjury that you have a good-faith belief the material was removed by mistake or misidentification; and your name, address, and telephone number, and a statement that you consent to the jurisdiction of the U.S. federal district court for the judicial district in which your address is located (or, if your address is outside the United States, any judicial district in which we may be found), and that you will accept service of process from the person who sent the original notice or that person's agent. We will promptly notify you if we remove your content because of a DMCA notice. If we receive a valid counter-notice, we will forward it to the person who sent the original notice and restore the material not less than 10 nor more than 14 business days after receiving the counter-notice, unless our designated agent first receives notice that the complaining party has filed a court action to restrain the alleged infringement.
  5. Under the DMCA, anyone who knowingly makes a material misrepresentation in a notice or counter-notice may be liable for damages.
  6. Repeat infringers: in appropriate circumstances, we will terminate the accounts of members who repeatedly infringe the copyrights of others.

US-5. Dispute Resolution, Binding Arbitration, and Class Action Waiver

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES U.S. MEMBERS TO RESOLVE MOST DISPUTES WITH US THROUGH INDIVIDUAL ARBITRATION INSTEAD OF IN COURT, AND IT WAIVES THE RIGHT TO A JURY TRIAL AND TO TAKE PART IN A CLASS ACTION. YOU MAY OPT OUT AS DESCRIBED BELOW.

  1. Informal resolution first. Before starting arbitration or a court case, you and we each agree to first try to resolve the dispute informally. Send a written notice to tididiapp@gmail.com with your name, the email or phone number of your account, a description of the dispute, and the relief you want. We will send our notice to the contact information of your account. If the dispute is not resolved within 60 days after the notice is received, either party may start arbitration. Any time limit for bringing a claim is paused during this 60-day period.
  2. Agreement to arbitrate. Except as stated in item 3, any dispute, claim, or controversy between you and us arising out of or relating to these Terms or the Service (a "Dispute") will be resolved by final and binding arbitration on an individual basis. The arbitrator decides all questions about the scope, enforceability, and interpretation of this agreement to arbitrate, except that a court decides questions about item 5 (Class Action and Jury Trial Waiver).
  3. Exceptions. Either party may (a) bring an individual claim in small claims court if it qualifies and stays in that court, and (b) ask a court for an injunction or other equitable relief to stop the infringement or misuse of intellectual property rights.
  4. Rules and procedure. The arbitration will be administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules then in effect (available at www.adr.org), as modified by this section. The Federal Arbitration Act governs the interpretation and enforcement of this section. Unless you and we agree otherwise, the arbitration will be held by video conference or in the county where you live; if your claim is US$10,000 or less, you may choose to have it decided on the written submissions alone. Payment of fees will be governed by the AAA's rules, which limit the fees a consumer pays. The arbitrator may award the same individual relief a court could award, but only in favor of the individual party seeking relief and only to the extent needed for that party's individual claim.
  5. Class Action and Jury Trial Waiver. YOU AND WE EACH AGREE THAT DISPUTES WILL BE BROUGHT ONLY ON AN INDIVIDUAL BASIS AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING, AND THAT YOU AND WE EACH WAIVE THE RIGHT TO A TRIAL BY JURY. If this item 5 is found unenforceable for a particular claim or request for relief, that claim or request (and only that claim or request) will be separated from the arbitration and decided by a court, after any individual claims have been arbitrated.
  6. Mass arbitration. If 25 or more similar demands for arbitration are filed against us by or with the help of the same or coordinated counsel or organizations, the AAA's Mass Arbitration Supplementary Rules will apply, to the extent they apply under the AAA's rules.
  7. Opt-out. You may opt out of this agreement to arbitrate by emailing tididiapp@gmail.com, with the subject line "Arbitration Opt-Out," within 30 days after you first accept these Terms (or after the date these Additional Terms first take effect for you, if later). Include your name, the email or phone number of your account, and a clear statement that you want to opt out of arbitration. Opting out does not affect any other part of these Terms.
  8. Changes. If we change this section after you accept it, the change will not apply to a Dispute of which we had notice before the change. If we make a change that is unfavorable to you, you may reject it by emailing us within 30 days after it takes effect, and the version of this section you previously accepted will continue to apply to you.
  9. If this section is not followed. If, for any reason, a Dispute proceeds in court rather than in arbitration (including because you opted out), the Dispute will be decided by a court of competent jurisdiction, and you may bring it in the state or federal courts for the county where you live.

US-6. Governing Law

For U.S. Members, these Terms are governed by the Federal Arbitration Act, applicable U.S. federal law, and the laws of the U.S. state where you live, without regard to conflict-of-laws rules. Article 14 (1) and (2) do not apply to U.S. Members.

US-7. Disclaimer of Warranties

TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING IMPLIED 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 DATA (INCLUDING RUNNING AND HEALTH FIGURES) WILL BE ACCURATE OR PRESERVED. SOME STATES DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THESE EXCLUSIONS MAY NOT APPLY TO YOU.

US-8. Limitation of Liability

  1. TO THE FULLEST EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
  2. TO THE FULLEST EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) US$100.
  3. These limits do not apply to liability that cannot be limited under applicable law, including liability for fraud, gross negligence, willful misconduct, or violation of law, or for death or personal injury caused by our negligence. Some states do not allow these limits, so they may not apply to you.

US-9. Your Responsibility for Your Content

To the extent permitted by law, you agree to compensate us for reasonable losses, including reasonable attorneys' fees, that arise from third-party claims caused by content you post or by your violation of these Terms or of the law. We will notify you of any such claim and may take part in its defense.

US-10. Apple App Store

US-11. Electronic Communications

You agree that we may give you notices and other communications electronically, such as through in-app notices or to the contact information of your account, and that these satisfy any legal requirement that such communications be in writing.

US-12. Notice for California Residents

The Service is provided free of charge. The Operator's contact information is in US-1.

AU-1. Operator Information

AU-2. Minimum Age

  1. You must be at least 18 years old to create an account or use the Service.
  2. Australian law requires age-restricted social media platforms to take reasonable steps to prevent people under 16 from having accounts. If we have reason to believe that an Australian Member is under 18, we may ask the member to confirm their age, and we may suspend or delete the account.
  3. If you think we have restricted your account by mistake, you can ask us to review it at tididiapp@gmail.com. We will not require a government-issued ID as the only way to confirm your age. Any information you give us to confirm your age is used only for that purpose and is destroyed once the review is finished.
  4. You can tell us about an account you believe belongs to someone under the minimum age by using the in-app report feature or by emailing tididiapp@gmail.com.

AU-3. Australian Consumer Law

  1. Our services come with guarantees that cannot be excluded under the Australian Consumer Law.

  2. Article 13 (Damages and Disclaimer) applies to Australian Members only to the extent permitted by law.

AU-4. Health and Safety

The Service is not a medical device and does not provide medical, health, or training advice. Figures shown in the Service, including those imported from a health app or a watch, may be inaccurate. Running involves risk of injury; consult a doctor before starting or changing an exercise program, and look after your own safety while running.

AU-5. Reports, Complaints, and Online Safety

  1. You can report posts, comments, messages, or accounts that are harmful, illegal, or that break these Terms using the in-app report feature, or by emailing tididiapp@gmail.com. We review reports and may remove content or restrict accounts under Article 10 and Article 11.
  2. If you have a complaint about how we handled a report or about a restriction on your account, email tididiapp@gmail.com with the subject line "Complaint." We aim to respond within 30 days.

AU-7. Governing Law

These Terms are governed by the laws of the Republic of Korea, without regard to its conflict-of-laws rules. This does not deprive you of the protection of the laws of your Australian state or territory that cannot be excluded by contract, including the Australian Consumer Law, and you may bring proceedings in the courts of your Australian state or territory of residence.
