Terms of Service

Last updated: May 12, 2026

These Terms of Service (the "Terms") constitute a binding agreement between you and Red Panda Technology Inc, a corporation organized under the laws of the Province of Ontario, Canada ("Company", "we", "us", or "our"), and govern your access to and use of (i) the Quartz email applications for macOS and iOS (the "App") and (ii) the website located at quartzmail.ai (the "Site", and together with the App, the "Services").

BY DOWNLOADING, INSTALLING, OR USING THE APP, OR BY ACCESSING OR USING THE SITE, YOU ACKNOWLEDGE THAT YOU HAVE READ THESE TERMS, UNDERSTAND THEM, AND AGREE TO BE BOUND BY THEM. IF YOU DO NOT AGREE TO THESE TERMS, DO NOT ACCESS OR USE THE SERVICES.

1. Eligibility

You represent and warrant that you are at least the age of majority in your jurisdiction and that you have full right, power, and authority to enter into these Terms. If you are using the Services on behalf of an entity, you further represent and warrant that you are authorized to bind that entity to these Terms, in which case "you" refers to that entity.

2. License

Subject to your continued compliance with these Terms, the Company grants you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and run the App on devices that you own or control, and to access and use the Site, in each case solely for your personal or internal business purposes and for use with email accounts that you are authorized to access.

The App is licensed, not sold. The Company and its licensors retain all right, title, and interest in and to the Services, including all intellectual-property rights therein. No rights are granted to you other than those expressly set out in these Terms.

If you obtain the App from a third-party application marketplace (including the Apple App Store), additional terms imposed by the operator of that marketplace may apply to your use of the App. In the event of a conflict between such operator's terms and these Terms with respect to the App obtained through that marketplace, the operator's terms shall prevail to the extent of the conflict.

3. Your accounts and content

The App is a client that connects to one or more email accounts you control with a third-party email provider (each, an "Email Provider"). You are solely responsible for: (a) maintaining the confidentiality and security of any credentials used to access your Email Provider; (b) ensuring that you are authorized to use those email accounts in connection with the App; and (c) all content you transmit, receive, store, or otherwise process through the App (your "Content").

As between you and the Company, you retain all right, title, and interest in your Content. You grant the Company only such limited rights to your Content as are necessary for the Services to provide their stated functionality on your device. Nothing in these Terms grants the Company a license to use your Content for any other purpose.

4. AI features

The App includes features powered by artificial-intelligence models (the "AI Features"). AI Features generate output by means of statistical and probabilistic methods, and such output may be inaccurate, incomplete, biased, or otherwise unsuitable for your intended purpose. You acknowledge and agree that you are solely responsible for reviewing, verifying, and exercising your independent judgment with respect to any output of the AI Features before relying on, transmitting, or otherwise acting upon it. AI output is provided on an "as is" basis and the Company makes no representation or warranty regarding the accuracy, reliability, fitness for purpose, or non-infringement of any such output.

Where AI Features are configured to operate by transmitting data to a third-party provider that you have selected and authorized, such transmission is made at your direction and is governed by the terms and privacy policy of that third-party provider. The Company is not responsible for the acts, omissions, availability, or content of any third-party provider.

5. Acceptable use

You shall not, and shall not permit any third party to:

  • use the Services in violation of any applicable law, regulation, or order, or in a manner that infringes, misappropriates, or otherwise violates the rights of any third party;
  • use the App to transmit unsolicited commercial communications, spam, fraudulent, harassing, defamatory, obscene, or otherwise unlawful content, or any content containing malware or other harmful code;
  • attempt to access, probe, or test the vulnerability of any system or network related to the Services, or to access accounts or data not belonging to you;
  • decompile, disassemble, reverse engineer, or otherwise attempt to derive the source code, underlying ideas, algorithms, file formats, or non-public interfaces of the Services, except to the extent that such restriction is prohibited by applicable law;
  • modify, adapt, translate, or create derivative works of the Services, or remove, alter, or obscure any proprietary notices contained in the Services;
  • rent, lease, lend, sell, resell, sublicense, distribute, or otherwise make the Services, or any service that incorporates the Services, available to any third party without the Company's prior written consent;
  • use any automated means to access, scrape, harvest, or extract data from the Site, except as expressly permitted by us;
  • interfere with, disrupt, or impose an unreasonable load on the Services or on any third-party service with which the Services interoperate; or
  • use the Services in any manner not expressly permitted by these Terms.

6. Third-party services

The Services interoperate with, and may rely on, services provided by third parties (including Email Providers and other service providers). Your use of any third-party service is governed by the terms and privacy policies of the applicable third party. The Company is not responsible for, and does not endorse or assume any liability for, any third-party services, content, or practices.

7. Updates

The Company may, but is not obligated to, make available updates, patches, upgrades, or other modifications to the Services from time to time. Such updates may be required for continued use of the Services and may add, modify, or remove functionality. These Terms apply to any update unless the update is accompanied by separate terms, in which case those separate terms shall govern.

8. Fees

The Services are currently provided without charge. The Company reserves the right to introduce paid functionality, subscription plans, or other fees in the future. Any such fees will be disclosed to you in advance, and you will not be charged any fee without your express agreement.

9. Intellectual property

The name "Quartz," the Quartz logo, and all marks, designs, copyrighted material, and other intellectual property associated with the Services are owned by the Company or its licensors and are protected by applicable intellectual-property and unfair-competition laws. Except as expressly set forth in these Terms, no license or other right is granted to you in respect of any such intellectual property.

The Services may incorporate open-source software components that are licensed under their respective terms. To the extent of any conflict between these Terms and the applicable open-source license with respect to such components, the open-source license shall govern.

10. Feedback

If you provide the Company with any suggestions, comments, improvements, ideas, or other feedback regarding the Services ("Feedback"), you hereby grant the Company a non-exclusive, perpetual, irrevocable, royalty-free, worldwide, sublicensable, and transferable license to use, reproduce, modify, and otherwise exploit such Feedback for any purpose, without any obligation or compensation to you.

11. Disclaimer of warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. THE COMPANY AND ITS LICENSORS, SUPPLIERS, AND SERVICE PROVIDERS HEREBY DISCLAIM ALL WARRANTIES AND CONDITIONS, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OF MERCHANTABILITY, MERCHANTABLE QUALITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING OUT OF COURSE OF DEALING, USAGE, OR TRADE. WITHOUT LIMITING THE FOREGOING, THE COMPANY DOES NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, THAT DEFECTS WILL BE CORRECTED, OR THAT THE SERVICES OR THE SERVERS THAT MAKE THEM AVAILABLE ARE FREE OF HARMFUL COMPONENTS.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE COMPANY, ITS AFFILIATES, OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, LICENSORS, OR SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, DATA, OR CONTENT, WHETHER ARISING IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHERWISE, AND WHETHER OR NOT THE COMPANY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, ARISING OUT OF OR RELATED TO YOUR USE OF, OR INABILITY TO USE, THE SERVICES.

THE AGGREGATE LIABILITY OF THE COMPANY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES, WHETHER IN CONTRACT, TORT, OR OTHERWISE, SHALL NOT EXCEED ONE HUNDRED CANADIAN DOLLARS (CAD $100). THE EXISTENCE OF MORE THAN ONE CLAIM SHALL NOT ENLARGE THIS LIMIT. THE LIMITATIONS IN THIS SECTION ARE ESSENTIAL ELEMENTS OF THE BARGAIN BETWEEN YOU AND THE COMPANY AND APPLY NOTWITHSTANDING THE FAILURE OF ANY ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

13. Indemnification

You agree to defend, indemnify, and hold harmless the Company and its affiliates, and their respective officers, directors, employees, agents, licensors, and suppliers, from and against any and all claims, demands, actions, liabilities, damages, losses, costs, and expenses (including reasonable legal fees) arising out of or related to (a) your use of, or inability to use, the Services; (b) your Content; (c) your violation of these Terms; (d) your violation of any applicable law or the rights of any third party, including any Email Provider; or (e) your selection and use of any third-party service in connection with the Services.

14. Term and termination

These Terms remain in effect until terminated. You may terminate these Terms at any time by ceasing all use of the Services, disconnecting your accounts from within the App, and uninstalling the App. The Company may suspend or terminate your access to all or any portion of the Services at any time, with or without notice, if we reasonably determine that you have violated these Terms or that your use of the Services poses a risk to the Company, its users, or any third party. Upon termination of these Terms, all licenses granted to you shall immediately cease. Sections 2 (last paragraph), 3, 4, 5, 6, 9 through 13, and 15 through 17 shall survive any termination of these Terms.

15. Changes to the Services and to these Terms

The Company may modify, suspend, or discontinue the Services, or any portion thereof, at any time. The Company may also modify these Terms from time to time. If the Company makes material changes to these Terms, the Company will revise the "Last updated" date set out above and, where reasonably practicable, provide notice through the Services. Your continued use of the Services following the effective date of any modification constitutes your acceptance of the modified Terms.

16. Governing law and jurisdiction

These Terms, and any dispute arising out of or related to these Terms or the Services, shall be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein, without regard to any conflict-of-laws rules that would require the application of the laws of any other jurisdiction. Each party irrevocably consents and submits to the exclusive jurisdiction of the courts located in Toronto, Ontario, Canada in respect of any such dispute. The United Nations Convention on Contracts for the International Sale of Goods does not apply to these Terms.

17. Miscellaneous

These Terms constitute the entire agreement between you and the Company with respect to the Services, and supersede all prior or contemporaneous understandings, agreements, representations, and warranties, whether written or oral, with respect to the subject matter hereof. If any provision of these Terms is held to be invalid or unenforceable, that provision shall be enforced to the maximum extent permissible, and the remaining provisions shall remain in full force and effect. No failure or delay by the Company to exercise any right under these Terms shall operate as a waiver of that right. You may not assign or transfer these Terms, by operation of law or otherwise, without our prior written consent; any attempted assignment without such consent is void. The Company may assign or transfer these Terms, in whole or in part, without restriction. These Terms do not, and are not intended to, confer any rights or remedies upon any person other than you and the Company.
