Uqbar — Behavioral tension insights · Last updated: August 21, 2026
These Terms of Use ("Terms") are a binding agreement between you and the developer of Uqbar ("Uqbar," "we," "us"). By downloading, installing, or using Uqbar, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the app.
Please read Section 14 carefully. It contains a binding arbitration provision and a class action waiver that affect your legal rights.
You must be at least 18 years old (or the age of majority in your jurisdiction, whichever is greater) to use Uqbar. By using the app, you represent that you meet this requirement. Uqbar is not directed to children.
Uqbar is an experimental observation tool. It estimates observable behavioral tension signals from video and voice. It is not a lie detector, not evidence, not a medical, psychological, or diagnostic device, and its output must never be treated as proof of truthfulness, deception, intent, health, or emotional state.
A change in someone's behavior can mean many things — stress, tiredness, thinking harder, discomfort, or nothing at all. Uqbar's output is an estimate with inherent error and has not been validated for, and must not be used for, any consequential decision about a person.
You agree that you will not use Uqbar or its output:
We may terminate or restrict your access to the app for violation of these Terms, without prejudice to any other remedy.
Uqbar is a tool that you operate on your device. All capture and processing of video, audio, and face data is initiated and controlled solely by you and occurs only on your device. You — not Uqbar's developer — decide what is recorded and analyzed, and you are solely responsible for complying with all laws that apply to that activity, including without limitation:
Uqbar's developer never receives, collects, possesses, stores, sells, or discloses any video, audio, face data, biometric identifier, or biometric information from your use of the app. See our Privacy Policy for details.
Uqbar includes a free daily allowance. Additional use requires consumable credits or an Uqbar Pro subscription, purchased through Apple's App Store.
Credits are consumed by analyses and live-session minutes as described in the app, have no cash value, are non-transferable, and are not refundable except as required by law or Apple's policies.
Subscriptions renew automatically until canceled at least 24 hours before the end of the current period. You can manage or cancel subscriptions in your App Store account settings. Refunds are handled by Apple under their terms. We do not offer lifetime purchases: Uqbar evolves continuously, and access is always tied to an active subscription or credit balance. Prices may change prospectively; changes apply at your next renewal after notice through the App Store.
Videos, audio and analysis results are processed and stored only on your device. You retain all rights to your content. We never receive it. You represent and warrant that you have all rights and consents necessary for any content you analyze with the app.
The app, including its software, design, signal definitions, scoring methods, and branding, is owned by Uqbar's developer and protected by intellectual property laws. We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the app on Apple-branded devices that you own or control, as permitted by the App Store terms, for your personal, lawful use. You may not copy, modify, distribute, sell, sublicense, reverse engineer, or create derivative works of the app except as permitted by law.
We may modify, suspend or discontinue features of Uqbar at any time. Signal definitions, scoring scales and analysis methods are experimental and may change between versions, which can alter the numbers the app shows for similar material. We may update these Terms; the "Last updated" date above will change, and material changes will be reflected in the app or on this site. Continued use after changes take effect constitutes acceptance.
Uqbar does not provide medical, psychological, legal, or professional advice. The camera-based pulse figure is a rough optical estimate, not a measurement from a medical device, and can be wrong or unavailable. Never rely on Uqbar for health decisions; consult a qualified professional. You assume all risk arising from your use of the app and its output, including any conclusion you draw about any person.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, UQBAR IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, ACCURACY, RELIABILITY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ITS ESTIMATES WILL BE ACCURATE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL UQBAR'S DEVELOPER BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR REPUTATION, OR FOR ANY DECISION MADE OR ACTION TAKEN IN RELIANCE ON THE APP'S OUTPUT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE APP SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) FIFTY U.S. DOLLARS (US$50). SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU. THE LIMITATIONS IN THIS SECTION ARE FUNDAMENTAL ELEMENTS OF THE BARGAIN BETWEEN YOU AND US.
You agree to defend, indemnify, and hold harmless Uqbar's developer from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use or misuse of the app or its output; (b) your violation of these Terms; (c) your violation of any law, including recording-consent and biometric privacy laws; or (d) your analysis of any person without required notice or consent.
These Terms and any dispute arising out of them are governed by the laws of the State of Delaware, U.S.A., without regard to its conflict of laws rules, except that the Federal Arbitration Act governs Section 14. If you are a consumer, you retain any protections of the mandatory consumer protection laws of your state or country of residence that cannot be waived by contract.
Informal resolution first. Before filing any claim, you and we agree to try to resolve the dispute informally: send a written description of the dispute to [email protected], and we will attempt in good faith to resolve it within 60 days. Most concerns can be resolved this way.
Arbitration. If the dispute is not resolved informally, you and we agree that any dispute, claim, or controversy arising out of or relating to these Terms or the app shall be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, rather than in court. The arbitration will be conducted in English, remotely by videoconference or documents-only where the rules allow, or in the county of your residence in the United States. Judgment on the award may be entered in any court of competent jurisdiction.
Class action and jury waiver. YOU AND WE EACH WAIVE THE RIGHT TO A TRIAL BY JURY AND THE RIGHT TO PARTICIPATE IN A CLASS ACTION, CLASS ARBITRATION, OR ANY OTHER REPRESENTATIVE PROCEEDING. Claims may be brought only in an individual capacity. If this class action waiver is found unenforceable as to a particular claim, then that claim (and only that claim) shall proceed in court, and the waiver shall remain in effect for all other claims.
Exceptions. Either party may bring an individual claim in small claims court, and either party may seek injunctive relief in court for infringement or misuse of intellectual property.
30-day opt-out. You may opt out of this arbitration agreement by emailing [email protected] with the subject "Arbitration opt-out" within 30 days of first accepting these Terms. Opting out of arbitration does not affect any other part of these Terms.
These Terms are between you and Uqbar's developer only — not Apple. Apple is not responsible for the app or its content, has no obligation to provide maintenance or support, and is not responsible for addressing any claim relating to the app, including product liability, legal compliance, or intellectual property claims. In case of the app's failure to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You represent that you are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government list of prohibited or restricted parties.
Under California Civil Code §1789.3, California users may contact the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs in writing at 1625 North Market Blvd., Suite N-112, Sacramento, California 95834, or by telephone at (800) 952-5210.
These Terms, together with the Privacy Policy, are the entire agreement between you and us regarding the app. If any provision is held invalid, the remaining provisions remain in full force. Our failure to enforce a provision is not a waiver. You may not assign these Terms; we may assign them in connection with a transfer of the app. Sections 2–4, 6–7, and 9–17 survive termination.
