You may not copy, decompile, reverse-engineer, disassemble, attempt to derive the source code of, modify, or create derivative works of the Service, any updates, or any part thereof (except as and only to the extent that any foregoing restriction is prohibited by applicable law or to the extent as may be permitted by the licensing terms governing use of any open-sourced components included with the Service).

One Duck Theory does not recognize any purported transfers of Virtual Items outside of the Service, or the purported sale, gift, or trade in the “real world” of anything that appears or originates in the Service. Virtual Items that may be originally acquired by “farming” are subject to confiscation by One Duck Theory. You may not sell Virtual Items for “real” money, or exchange those Virtual Items for value outside of the Service. To be clear, Virtual Items have no real-world value and are licensed, not owned.

Under no circumstances will refunds be given for Virtual Items. All sales of Virtual Items are final when the transaction has been processed.

7. Support Services

One Duck Theory may, in its sole discretion, provide you with customer and technical support services related to the Service (“Support Services”). One Duck Theory is not required to provide Support Services unless otherwise required by applicable law. No failure to provide, or to continue to provide, Support Services will be a default of One Duck Theory under this Agreement. Any supplemental software code provided to you as part of the Support Services will be treated as part of the Service, and as between you and One Duck Theory will be and remain the sole property of One Duck Theory and will be subject to the terms and conditions of this Agreement.

13. Disclaimer of Warranties

Your use of the Service is entirely at your own risk.

The Service is provided by One Duck Theory on an as-is basis. One Duck Theory expressly disclaims all warranties of any kind, whether express or implied, including, but not limited to the implied warranties of merchantability, fitness for a particular purpose and non-infringement.

One Duck Theory makes no warranty that (i) the Service will meet your requirements, (ii) that operation of the Service will be uninterrupted, timely, secure, or error-free, or (iii) the results that may be obtained from the use of the Service will be accurate or reliable.

No advice or information, whether oral or written, obtained by you from One Duck Theory, or through the Service creates any warranty regarding the Service not expressly stated in this Agreement.

Because some states or jurisdictions do not allow the disclaimer of implied warranties, the foregoing disclaimer may not apply to you.

Apple Users: In the event of any failure of the Service to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the Service to you. Additionally, to the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the Service, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty, if any, will be One Duck Theory’s sole responsibility. 

14. Limitation of Liability

You expressly understand and agree that One Duck Theory is not liable for any direct, indirect, incidental, special, consequential, or exemplary damages, including damages for loss of profits, goods, goodwill, use, data, or other intangible losses (even if One Duck Theory has been advised of the possibility of such damages), resulting from the use or the inability to use the Service or any other matter relating to the Service.

Because some states or jurisdictions do not allow the exclusion or the limitation of liability for consequential or incidental damages, in such states or jurisdictions, the liability of One Duck Theory and its affiliates will be limited to the fullest extent permitted by law.

Apple Users: Both you and One Duck Theory acknowledge that One Duck Theory, not Apple, are responsible for addressing any user claims or any third party claims relating to the Service or your possession and/or use of the Service, including, but not limited to: (i) product liability claims; (ii) any claim that the Service fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation, including in connection with the Service’s use of the HealthKit and HomeKit frameworks.

15. Indemnification

You agree to indemnify and hold One Duck Theory and its affiliates, officers, agents, and employees harmless from any claim, demand, loss, costs, or expense, including attorneys’ fees, made by any person or entity arising out of your violation of this Agreement, state or federal laws or regulations, or any other person’s rights, including infringement of any copyright or violation of any proprietary or privacy right. Under no circumstances, including any negligent act, will One Duck Theory or its affiliates or agents be liable for any damages of any kind that result from the use of, or the inability to use, the Service.

16. Your Personal Information

Certain personal and other information that we collect, process, and share is subject to our Privacy Policy.  As a condition of using the Service you agree to the terms of the Privacy Policy, as it may be changed from time to time. Our Privacy Policy, which is incorporated here by reference, is located at https://oneducktheory.com/privacy/. You agree that your use of the Service is subject to the Privacy Policy.

17. Disclosures Required by Law

One Duck Theory reserves the right to disclose any information, including personally identifiable information about you, as necessary to satisfy any applicable law, regulation, legal process, or governmental request. One Duck Theory reserves the right to fully cooperate with any law enforcement authorities or court order requesting or directing One Duck Theory to disclose the identity of any user believed to be in violation of this Agreement.

By accepting this Agreement, you waive all rights and agree to hold One Duck Theory harmless from any claims resulting from any action taken by One Duck Theory during or as a result of its investigations or from any actions taken as a consequence of investigations by either One Duck Theory or law enforcement authorities.

18. Legal Compliance

By using the Service, you represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

19. Third-Party Beneficiary

Apple Users: You and One Duck Theory acknowledge and agree that Apple, and Apple’s subsidiaries, are third party beneficiaries of this Agreement, and that, upon your acceptance of the terms and conditions of this Agreement, Apple will have the right (and will be deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary thereof.

20. Governing Law; Mediation; Jurisdiction

The Agreement, and all future agreements you enter into with One Duck Theory, unless otherwise indicated on such other agreement, will be governed by the laws of the State of Massachusetts. This is the case regardless of whether you reside or transact business with One Duck Theory, or any of its affiliates or agents, in the State of Massachusetts or elsewhere. Unless a dispute would be governed by the terms of Section 21 below, you agree to submit to the personal and exclusive jurisdiction of the courts located within the city of Boston, Massachusetts, United States.

For EU users only: In the event of a dispute relating to the interpretation, performance, or validity of this Agreement, an amicable solution can be sought before any legal action. You can file your complaint with One Duck Theory by sending a message via email to [email protected]. In case of failure, you can, within one year of the failed request, have recourse to an Alternative Dispute Resolution procedure by filing an online complaint on the European Commission’s Online Dispute Resolution website: https://webgate.ec.europa.eu/odr/main/index.cfm?event=main.home.chooseLanguage. In the event that out-of-court dispute resolutions fail, the dispute may be brought before the competent courts.

21. Binding Arbitration

Any dispute or claim relating in any way to your use of the Service (each, a “Claim”) will be resolved by binding arbitration, rather than in court (except that you may assert claims in small-claims court if your claims qualify). You agree that each Claim must be brought individually.


The Federal Arbitration Act and federal arbitration law apply to this Agreement and this binding arbitration clause.

Arbitration is a process with no judge or jury – an arbitrator will review the arguments in the dispute and award damages and other relief just like a court would. The arbitrator must follow this Agreement as a court otherwise would. Court review of the arbitration award is limited under the Federal Arbitration Act.

To start an arbitration, you must send an email to [email protected] describing your Claim and requesting arbitration, or we may do the same by sending a written notice requesting arbitration to your address. The proceedings will be conducted through JAMS, using their Streamlined Arbitration Rules and Procedures. You can view these rules at jamsadr.com or by calling 800-352-5267. The payment of the initial filing fees will be made by the party filing the Claim, and any other filing and other fees will be apportioned as directed by the JAMS rules. The arbitration will take place in Boston, Massachusetts, United States, unless the Parties agree to video, phone, or internet connection appearances.

Except as otherwise set forth below, you may seek any remedies available to you under federal, state or local laws in an arbitration action. As part of the arbitration, both you and One Duck Theory will have the opportunity for discovery of non-privileged information that is relevant to the Claim. The arbitrator will provide a written statement of the arbitrator’s decision regarding the Claim, the award given (including any attorneys’ fees and costs awarded), and the arbitrator’s findings and conclusions on which the arbitrator’s decision is based.

Notwithstanding the terms of this Section, either of us may bring a lawsuit in court for equitable relief, for any misuse or infringement of intellectual property rights, or for any Claim related to, or arising from, allegations of theft, piracy, invasion of privacy, or unauthorized use of the Service.


You and One Duck Theory agree that if any portion of this Section is found illegal or unenforceable, that portion will be severed and the remainder of the Section will be given full force and effect.

22. Miscellaneous Terms

22.1 Agreement Revisions. This Agreement may only be revised in writing by One Duck Theory, or by One Duck Theory’s publication of a new version on the Service.

22.2 Force Majeure. One Duck Theory is not liable for any delay or failure to perform resulting from causes outside the reasonable control of One Duck Theory, including without limitation any failure to perform hereunder due to unforeseen circumstances or cause beyond One Duck Theory’s control such as acts of God, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, accidents, strikes, or shortages of transportation facilities, fuel, energy, labor, or materials.

22.3 No Partnership. You agree that no joint venture, partnership, employment, or agency relationship exists between you and One Duck Theory as a result of this Agreement or your use of the Service.

22.4 Assignment. One Duck Theory may assign this Agreement, in whole or in part, to any person or entity at any time with or without your consent. You may not assign the Agreement without One Duck Theory’s prior written consent, and any unauthorized assignment by you will be null and void.

22.5 Severability. If any part of this Agreement is determined to be void, invalid or unenforceable, then that portion will be severed, and the remainder of the Agreement will be given full force and effect.

22.6 Attorneys’ Fees. In the event any litigation is brought by either party in connection with this Agreement, the prevailing party in such litigation will be entitled to recover from the other party all the reasonable costs, attorneys’ fees and other expenses incurred by such prevailing party in the litigation.

22.7 No Waiver. Our failure to enforce any provision of this Agreement will in no way be construed to be a present or future waiver of such provision, nor in any way affect the right of any party to enforce every such provision thereafter. The express waiver by us of any provision, condition or requirement of this Agreement will not constitute a waiver of any future obligation to comply with such provision, condition or requirement.

22.8 Equitable Remedies. You hereby agree that One Duck Theory would be irreparably damaged if the terms of this Agreement were not specifically enforced, and therefore you agree that we will be entitled, without bond, other security, or proof of damages, to appropriate equitable remedies with respect to breaches of this Agreement, in addition to such other remedies as we may otherwise have available to us under applicable laws.

22.9 Entire Agreement. This Agreement, including the documents expressly incorporated by reference, constitutes the entire agreement between you and One Duck Theory with respect to the Service and supersedes all prior or contemporaneous communications, whether electronic, oral or written, between you and One Duck Theory with respect to the Service.
