Effective date: April 14, 2026
Last updated: April 14, 2026

These Terms of Use (“Terms”) constitute a legally binding agreement between you (“you,” “your,” or “User”) and Yakura LLC (“Yakura,” “we,” “us,” or “our”), governing your access to and use of the QR Scanner mobile application (the “App”) and any related services we provide. BY DOWNLOADING, INSTALLING, OR USING THE APP, YOU AGREE TO BE BOUND BY THESE TERMS IN THEIR ENTIRETY. IF YOU DO NOT AGREE, YOU MUST IMMEDIATELY UNINSTALL AND CEASE ALL USE OF THE APP.

PLEASE READ THESE TERMS CAREFULLY. THEY INCLUDE IMPORTANT INFORMATION ABOUT YOUR LEGAL RIGHTS, INCLUDING DISCLAIMERS OF WARRANTIES, LIMITATIONS OF LIABILITY, AN AGREEMENT TO RESOLVE DISPUTES BY BINDING INDIVIDUAL ARBITRATION, AND A WAIVER OF YOUR RIGHT TO PARTICIPATE IN A CLASS ACTION OR JURY TRIAL.

If you are using the App on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

2. Eligibility

You must be at least 13 years old (or 16 in jurisdictions where that is the applicable minimum age) to use the App. By using the App, you represent and warrant that you meet this age requirement and that you have the legal capacity to enter into a binding agreement. If you are a minor in your jurisdiction, you may use the App only with the involvement and consent of a parent or legal guardian.

YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT YOUR USE OF THE APP IS AT YOUR SOLE RISK. You assume full responsibility and risk of loss resulting from your use of, or inability to use, the App, including but not limited to:

  • Any link, URL, address, payment instruction, Wi-Fi credential, contact, or other actionable content encoded in a QR code or barcode that you choose to open, follow, execute, or rely upon
  • Any phishing attempt, scam, fraud, malware, ransomware, malicious software, harmful website, or other security threat that may be reached through scanned content
  • Any financial loss, identity theft, account compromise, or other harm resulting from acting on scanned content
  • Any data charges, network usage, battery consumption, device wear, storage exhaustion, or interference with other applications
  • Any loss of data, configuration, history, or settings stored locally by the App
  • Any consequence of granting, denying, or revoking system permissions used by the App

You agree that you alone are responsible for evaluating any content or action prompted by the App before relying on or acting upon it.

5. User Conduct

You agree not to use the App to:

  • Violate any applicable law, regulation, or third-party right
  • Scan, generate, distribute, or share QR codes or barcodes containing illegal, harmful, fraudulent, defamatory, obscene, infringing, or otherwise objectionable content
  • Engage in phishing, identity theft, fraud, scams, or any deceptive practice
  • Distribute malware, viruses, ransomware, or any code intended to disrupt or damage software, hardware, or telecommunications equipment
  • Interfere with or disrupt the App, our servers, or the networks connected to the App
  • Attempt to gain unauthorized access to any portion of the App, related systems, or other users’ devices
  • Use the App in any way that could harm minors
  • Use any automated means (bots, scrapers, etc.) to access the App
  • Use the App in connection with any commercial purpose without our prior written consent

You are solely and exclusively responsible for the content of the QR codes and barcodes you scan, generate, share, or otherwise interact with using the App, and for any consequences arising therefrom.

6. Intellectual Property

The App, including its source code, design, layout, graphics, icons, text, audio, video, and all other content (excluding User-generated content), is owned by Yakura or its licensors and is protected by copyright, trademark, trade secret, and other intellectual property laws. The “QR Scanner” name, logo, and all related marks are trademarks of Yakura LLC.

The App incorporates open-source software components, each licensed under its respective open-source license. Acknowledgements and license texts for these components are available within the App’s settings or upon request.

Nothing in these Terms transfers any intellectual property rights to you, except for the limited license expressly granted in Section 3.

7. User Content

The App allows you to generate QR codes and barcodes from content you provide (“User Content”). You retain all rights in your User Content. You represent and warrant that you own or have all necessary rights to your User Content and that it does not infringe any third-party rights or violate any law.

User Content is processed and stored entirely on your device. Yakura does not access, collect, or transmit your User Content. You are solely responsible for backing up, securing, and managing your User Content.

8. Third-Party Services and Links

The App integrates third-party services, including Google Firebase, Google ML Kit, Google Play Services, and the Google Mobile Ads SDK (AdMob). Your use of these services is also subject to the applicable third-party terms and privacy policies. Yakura is not responsible for the practices, performance, availability, or content of any third-party service.

QR codes and barcodes you scan may contain links to third-party websites, applications, networks, payment systems, or services. When you choose to interact with such content, you do so entirely at your own risk and subject to the third party’s own terms and policies. Yakura does not endorse, screen, verify, vouch for, or accept any responsibility for any third-party content, products, services, or actions.

8A. Advertising

Ad-Supported App. The App is provided free of charge and is funded by advertising delivered through Google AdMob (operated by Google LLC). By using the App, you acknowledge and agree that advertisements may be displayed within the App, and that Yakura may collect advertising delivery and measurement data as described in our Privacy Policy, Section 1.7.

No Endorsement. Advertisements displayed in the App are served dynamically by AdMob and its advertising partners. Yakura does not select, pre-screen, endorse, sponsor, or verify individual advertisements or advertisers. The appearance of any advertisement in the App does not constitute an endorsement or recommendation by Yakura of the advertised product, service, website, application, company, or offer.

No Liability for Ad Content. You acknowledge and agree that Yakura is not responsible or liable, directly or indirectly, for any loss or damage caused or alleged to be caused by or in connection with: (a) the content, accuracy, completeness, or legality of any advertisement; (b) any product, service, website, application, or offer promoted through an advertisement; (c) any transaction, purchase, or interaction you enter into with any advertiser; (d) any malware, phishing, scam, fraud, deceptive content, or harmful material reached through an advertisement; or (e) any act or omission of Google, AdMob, or any advertiser, ad network, or advertising partner. Your dealings with, or participation in promotions of, any advertiser found on or through the App are solely between you and the advertiser.

Ad Blocking and Tampering. You agree not to use any means (including ad blockers, hosts-file tampering, reverse-engineering, patching, or automated tools) to block, hide, interfere with, remove, or modify the display or delivery of advertisements in the App, except where such measures cannot be restricted under applicable law. Interfering with the advertising that funds the App is a material breach of these Terms and may result in termination of your license under Section 3.

Advertising Preferences. You can manage your advertising experience at any time by: (a) resetting or removing your device’s Advertising ID from Settings → Google → Ads (or the equivalent on your device); (b) enabling “Opt out of Ads Personalization”; or (c) using a Google-recognized consent mechanism where available in your region. Exercising these controls will not affect your ability to use the App, but may result in non-personalized (contextual) advertising being shown instead of personalized ads.

9. App Store Terms

If you download the App from the Google Play Store, Amazon Appstore, or any other distribution platform, your use is also subject to that platform’s terms of service. In the event of a conflict between these Terms and the platform’s terms regarding your use of the App, these Terms will govern except where the platform’s terms expressly provide otherwise.

10. Updates and Modifications

We may release updates, upgrades, patches, and new versions of the App from time to time. These updates may be installed automatically through your device’s app store. You agree that Yakura has no obligation to provide any updates, support, maintenance, or new features, and that any updates we choose to provide are subject to these Terms unless accompanied by separate terms.

11. Disclaimers of Warranty

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE APP AND ALL RELATED CONTENT, FEATURES, AND SERVICES ARE PROVIDED ON AN “AS IS,” “AS AVAILABLE,” AND “WITH ALL FAULTS” BASIS, WITHOUT WARRANTIES OF ANY KIND WHATSOEVER, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE.

THIS LIMITATION APPLIES REGARDLESS OF THE LEGAL THEORY ON WHICH THE CLAIM IS BASED — INCLUDING CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, STATUTE, OR ANY OTHER LEGAL OR EQUITABLE THEORY — AND APPLIES EVEN IF YAKURA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, EVEN IF A REMEDY SET FORTH HEREIN IS FOUND TO HAVE FAILED OF ITS ESSENTIAL PURPOSE, AND EVEN IF SUCH DAMAGES WERE FORESEEABLE.

AGGREGATE CAP. TO THE FULLEST EXTENT PERMITTED BY LAW, THE YAKURA PARTIES’ TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS, THE APP, OR YOUR USE OF THE APP, FROM ALL CAUSES OF ACTION AND UNDER ALL THEORIES OF LIABILITY, SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL AMOUNT, IF ANY, YOU HAVE PAID DIRECTLY TO YAKURA FOR THE APP IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE U.S. DOLLAR (USD $1.00). YOU ACKNOWLEDGE THAT THE APP IS PROVIDED TO YOU FREE OF CHARGE AND THAT YAKURA WOULD NOT BE ABLE TO PROVIDE THE APP WITHOUT THESE LIMITATIONS.

BASIS OF THE BARGAIN. THE LIMITATIONS IN THIS SECTION ARE A FUNDAMENTAL ELEMENT OF THE BARGAIN BETWEEN YOU AND YAKURA. THE APP WOULD NOT BE PROVIDED TO YOU WITHOUT SUCH LIMITATIONS.

JURISDICTIONAL CARVE-OUT. Some jurisdictions do not allow the exclusion or limitation of liability for incidental, consequential, or certain other damages, or for personal injury caused by gross negligence, willful misconduct, or fraud. Nothing in these Terms is intended to exclude or limit any liability that cannot lawfully be excluded or limited. In such jurisdictions, the Yakura Parties’ liability shall be limited to the greatest extent permitted by applicable law.

13. Indemnification

You agree to indemnify, defend, and hold harmless Yakura LLC, its affiliates, officers, directors, employees, agents, and licensors from and against any and all claims, demands, actions, losses, liabilities, damages, judgments, settlements, costs, and expenses (including reasonable attorneys’ fees and court costs), whether known or unknown, arising out of or in any way connected with: (a) your access to or use of the App; (b) your violation of these Terms; (c) your violation of any third-party right, including any intellectual property, privacy, or publicity right; (d) any content you generate, scan, share, distribute, or otherwise interact with using the App; (e) any harm caused to a third party through your use of the App; or (f) your negligence or willful misconduct.

We reserve the right, at our own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, in which event you will cooperate with us in asserting any available defenses. You agree not to settle any matter without our prior written consent.

14. Force Majeure

The Yakura Parties shall not be liable for any failure or delay in performance under these Terms resulting from any cause beyond our reasonable control, including but not limited to: acts of God, natural disasters, epidemics or pandemics, war, terrorism, civil unrest, riots, embargoes, governmental actions or orders, labor disputes, internet or telecommunications failures, power failures, hardware failures, software failures, third-party service outages (including failures of Google services or app stores), security incidents, data breaches affecting third-party providers, or any other event beyond our reasonable control. During any such event, our obligations under these Terms shall be suspended for the duration of the event.

15. Time Limitation on Claims

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR RELATING TO YOUR USE OF THE APP OR THESE TERMS MUST BE FILED WITHIN ONE (1) YEAR AFTER SUCH CLAIM OR CAUSE OF ACTION AROSE, OR BE FOREVER BARRED. THIS LIMITATION APPLIES REGARDLESS OF ANY STATUTE OF LIMITATIONS TO THE CONTRARY. WHERE APPLICABLE LAW PROHIBITS THIS SHORTENED LIMITATION PERIOD, THE STATUTORY PERIOD SHALL APPLY, BUT IN NO EVENT SHALL CLAIMS BE BROUGHT AFTER THE LATEST DATE PERMITTED BY LAW.

16. Termination

These Terms remain in effect for as long as you use the App. You may terminate these Terms at any time by uninstalling the App and ceasing all use of it.

We may suspend, restrict, or terminate your access to the App at any time, with or without notice, with or without cause, and at our sole discretion. Upon termination: (a) your right to use the App immediately ceases; (b) we shall have no liability to you whatsoever for the termination; and (c) all provisions of these Terms that by their nature should survive termination shall continue in full force and effect, including without limitation Sections 4 (Assumption of Risk), 5 (User Conduct), 6 (Intellectual Property), 11 (Disclaimers), 12 (Limitation of Liability), 13 (Indemnification), 14 (Force Majeure), 15 (Time Limitation), 17 (Governing Law and Dispute Resolution), and this Section 16.

17. Governing Law and Dispute Resolution

Governing Law. These Terms shall be governed by and construed in accordance with the laws of the State of Wyoming, United States, without regard to its conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Binding Arbitration. Any dispute, claim, or controversy arising out of or relating to these Terms or the App shall be resolved exclusively through final and binding individual arbitration administered in accordance with the rules of a recognized arbitration body, with the seat of arbitration in Cheyenne, Wyoming, and not in court, except that either party may bring claims in small-claims court if eligible.

Class Action Waiver. YOU AND YAKURA 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, REPRESENTATIVE, OR CONSOLIDATED PROCEEDING. UNLESS BOTH PARTIES AGREE OTHERWISE, THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON’S CLAIMS AND MAY NOT OTHERWISE PRESIDE OVER ANY FORM OF A REPRESENTATIVE OR CLASS PROCEEDING.

Jury Trial Waiver. YOU AND YAKURA EXPRESSLY WAIVE ANY RIGHT TO A TRIAL BY JURY.

Equitable Relief. Notwithstanding the foregoing, Yakura may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property or confidential information.

Consumer Carve-Out. If you are a consumer in the European Union, the United Kingdom, or any other jurisdiction where mandatory consumer-protection law overrides this Section 17, you may bring proceedings in the courts of your place of residence and rely on the mandatory consumer-protection laws of your country. Nothing in this Section is intended to deprive you of rights that cannot be waived under applicable law.

18. Changes to These Terms

We may modify these Terms from time to time. When we make material changes, we will revise the “Effective date” and “Last updated” dates at the top of this page and, where appropriate, provide additional notice within the App. Your continued use of the App after the updated Terms take effect constitutes your acceptance of the changes. If you do not agree to the modified Terms, you must immediately stop using the App.

19. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, that provision shall be modified to the minimum extent necessary to make it enforceable, or, if it cannot be made enforceable, it shall be severed from these Terms, and the remaining provisions shall remain in full force and effect. The invalidity or unenforceability of any provision shall not affect the validity or enforceability of any other provision.

20. Waiver

No failure or delay by Yakura in exercising any right, power, or remedy under these Terms shall constitute a waiver of that right, power, or remedy, nor shall any single or partial exercise preclude any other or further exercise. No waiver shall be effective unless made in writing and signed by an authorized representative of Yakura.

21. Assignment

You may not assign or transfer these Terms or any rights or obligations hereunder, by operation of law or otherwise, without our prior written consent, and any attempted assignment without such consent shall be null and void. Yakura may freely assign or transfer these Terms, in whole or in part, without restriction, including in connection with a merger, acquisition, sale of assets, or by operation of law.

22. No Agency or Partnership

Nothing in these Terms creates any agency, partnership, joint venture, employment, or fiduciary relationship between you and Yakura. Neither party has the authority to bind the other in any manner.

23. Notices

Any notice required or permitted to be given to Yakura under these Terms must be sent in writing to the contact address in Section 25. We may provide notices to you through in-app messages, push notifications, or any other reasonable means.
