Terms of Service

Last updated: June 26, 2026

These Terms of Service ("Terms") govern your access to and use of the Tethry remote-desktop software, websites, applications, and related services (collectively, the "Service") provided by Tethry ("Tethry," "we," "us," or "our"). By creating an account, installing our software, or otherwise using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Acceptance and Eligibility

You must be at least 16 years old to use the Service. By using the Service, you represent and warrant that you are at least 16 years old, that you have the legal capacity to enter into these Terms, and that you are not barred from using the Service under any applicable law. If you use the Service on behalf of an organization, you represent that you have authority to bind that organization, and "you" includes that organization.

2. Description of the Service

Tethry enables you to install a small Windows application on a computer (the "Host") and control that computer remotely from a phone or any web browser (the "Viewer"). Remote sessions are end-to-end encrypted, and our relay forwards only sealed packets that it cannot read. We provide connection-event logging (such as IP addresses, approximate geolocation, ISP, timestamps, and session duration) to power your security dashboard. The Service, including its features and availability, may change over time as described in these Terms.

3. Accounts, Security, and Responsibilities

To use most features, you must create an account through our authentication provider (Supabase) using an email and password or Google sign-in. You agree to:

  • Provide accurate, current, and complete information and keep it updated.
  • Keep your credentials confidential and not share your account.
  • Be solely responsible for all activity that occurs under your account.
  • Maintain the security of the devices you connect through the Service.
  • Notify us promptly at [email protected] of any unauthorized use or suspected security breach.

You are responsible for any loss arising from unauthorized use of your account that results from your failure to maintain its security. We are not liable for any loss or damage arising from your failure to comply with this Section.

4. Acceptable Use

You agree not to, and not to permit or enable anyone else to:

  • Use the Service for any illegal, fraudulent, or unauthorized purpose, or to access or control any computer or system that you do not own or that you are not expressly authorized to access and control.
  • Gain or attempt to gain unauthorized access to any system, account, data, or network.
  • Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, structure, or underlying ideas of the Service, except to the limited extent such restriction is prohibited by applicable law.
  • Copy, modify, distribute, sell, sublicense, lease, rent, or resell the Service, or make it available to third parties, except as expressly permitted.
  • Interfere with, disrupt, overload, or impair the Service, our infrastructure, or our relay, including by introducing malware or attempting denial-of-service attacks.
  • Circumvent or attempt to circumvent any security, authentication, usage-limit, or access-control measures.
  • Use the Service to transmit unlawful, infringing, harmful, or harassing content, or to violate the rights of others.
  • Use automated means to access the Service except through interfaces we expressly provide.
  • Violate any applicable law, regulation, or third-party right in connection with your use of the Service.

We may investigate and take any action we deem appropriate for violations of this Section, including removing content, suspending or terminating accounts, and reporting activity to authorities.

5. Subscriptions, Billing, and Renewals

5.1 Plans and Free Trial

The Service is offered on a subscription basis. We currently offer a 14-day free trial that does not require a payment card, after which paid plans are available: Personal at $5 per month and Team at $12 per user per month. We also offer one-time "add time" purchases. Plan features, limits, and prices are described at the point of sale. We may modify or discontinue the free trial or any plan at any time.

5.2 Payment

Paid plans and one-time purchases are billed through our payment processor, Stripe. You authorize us and Stripe to charge your selected payment method for all applicable fees, including taxes. Tethry does not store full payment card numbers. You represent that you are authorized to use the payment method you provide.

5.3 Auto-Renewal

Unless you cancel before the end of the current billing period, your subscription will automatically renew for successive periods of the same length, and your payment method will be charged the then-current fee for the renewal term. You may cancel auto-renewal at any time through your account settings; cancellation takes effect at the end of the current billing period.

5.4 No Refunds

Except where required by applicable law, all fees and charges are non-refundable, and we do not provide refunds or credits for partial billing periods, unused time, downgrades, one-time "add time" purchases, or features not used. If you cancel, you may continue to use the paid features until the end of your current billing period.

5.5 Price Changes

We may change our prices and introduce new fees at any time. For recurring subscriptions, we will provide notice of price changes, for example by posting on our website or notifying you through the Service, before they take effect. Price changes will apply to your next billing period after the notice. Your continued use of the Service after a price change takes effect constitutes acceptance of the new price; if you do not agree, you may cancel before the change applies.

5.6 Taxes

Fees are exclusive of taxes unless stated otherwise. You are responsible for all applicable taxes, duties, and similar charges, other than taxes based on our net income.

6. License Grant

Subject to your compliance with these Terms and payment of applicable fees, Tethry grants you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to install and use the Tethry software and Service for your own internal or personal use during your subscription term. All rights not expressly granted are reserved by Tethry.

7. Intellectual Property

The Service, including all software, source code, designs, text, graphics, logos, the "Tethry" name and brand, and all related intellectual property, is owned by Tethry or its licensors and is protected by intellectual property laws. These Terms do not transfer any ownership rights to you. You may not use our trademarks, logos, or branding without our prior written permission.

As between you and Tethry, you retain ownership of your own data and the contents of your remote sessions. Because sessions are end-to-end encrypted, we do not access their contents. You grant us a limited license to process account, connection, and operational data solely as necessary to provide, secure, and improve the Service and as described in our Privacy Policy.

7.1 Feedback

If you provide suggestions, ideas, or other feedback about the Service, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use it for any purpose without obligation or compensation to you.

8. Third-Party Services

The Service relies on third-party providers, including Stripe, Supabase, Cloudflare, ipapi.co, and Fontshare. Your use of certain features may be subject to those providers' terms. We are not responsible for third-party services, and your dealings with them are at your own risk.

9. Disclaimers; "AS IS"

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. TETHRY DISCLAIMS ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS, OR THAT ANY DATA WILL BE ACCURATE, PRESERVED, OR FREE FROM LOSS. YOU USE THE SERVICE AT YOUR OWN RISK. NO ADVICE OR INFORMATION OBTAINED FROM TETHRY CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TETHRY AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, DATA, OR BUSINESS, OR FOR ANY SERVICE INTERRUPTION OR DOWNTIME, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, WHETHER BASED ON CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY, OR ANY OTHER THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL CUMULATIVE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNTS YOU ACTUALLY PAID TO TETHRY FOR THE SERVICE IN THE THREE (3) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) FIFTY U.S. DOLLARS ($50).

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU. IN SUCH CASES, OUR LIABILITY WILL BE LIMITED TO THE FULLEST EXTENT PERMITTED BY LAW.

11. Indemnification

You agree to defend, indemnify, and hold harmless Tethry and its officers, directors, employees, agents, suppliers, and licensors from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of or access to the Service; (b) your violation of these Terms; (c) your violation of any law or any third-party right, including any unauthorized access to or control of any computer or system; or (d) any content or data you transmit through the Service. We reserve the right to assume the exclusive defense and control of any matter subject to indemnification, in which case you agree to cooperate with us.

12. Suspension and Termination

We may suspend, restrict, or terminate your access to the Service or your account, in whole or in part, at any time and at our sole discretion, with or without notice, including if we believe you have violated these Terms, pose a security or legal risk, or for any other reason. You may stop using the Service and cancel your account at any time.

Upon termination, your license to use the Service ends immediately. Except where required by law, fees already paid are non-refundable. Sections that by their nature should survive termination — including ownership, disclaimers, limitation of liability, indemnification, and dispute resolution — will survive.

13. Modifications to the Service and These Terms

We reserve the right, at our sole discretion, to modify, suspend, or discontinue the Service or any part of it at any time, with or without notice. We also reserve the right to modify these Terms at any time. When we make material changes, we will post the updated Terms on our website and update the "Last updated" date, and may provide additional notice through the Service. Changes take effect when posted unless otherwise stated. Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms. If you do not agree, you must stop using the Service.

14. Governing Law

These Terms and any dispute arising out of or relating to them or the Service are governed by the laws of the State of California, United States, without regard to its conflict-of-laws principles. Subject to the arbitration provisions below, the state and federal courts located in the State of California, United States will have exclusive jurisdiction over any disputes not subject to arbitration, and you consent to personal jurisdiction and venue there.

15. Binding Arbitration and Class-Action Waiver

PLEASE READ THIS SECTION CAREFULLY, AS IT AFFECTS YOUR LEGAL RIGHTS.

Except as otherwise provided below, you and Tethry agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved by final and binding arbitration on an individual basis, rather than in court. Arbitration will be administered by a recognized arbitration provider under its applicable rules, and judgment on the award may be entered in any court of competent jurisdiction.

Class-Action Waiver. You and Tethry agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. The arbitrator may not consolidate more than one person's claims and may not preside over any form of representative or class proceeding.

Exceptions. Either party may bring an individual claim in small-claims court, and either party may seek injunctive or equitable relief in court to protect its intellectual property or confidential information. To the extent any claim is found not subject to arbitration, it will proceed in the courts identified in Section 14.

Opt-Out. Where required by applicable law, you may opt out of this arbitration agreement by sending written notice to [email protected] within 30 days of first accepting these Terms.

16. DMCA and Copyright Notices

We respect intellectual property rights. If you believe content accessible through the Service infringes your copyright, send a notice to [email protected] that includes: (a) identification of the copyrighted work; (b) identification of the allegedly infringing material and its location; (c) your contact information; (d) a statement that you have a good-faith belief that the use is not authorized; (e) a statement, under penalty of perjury, that the information is accurate and that you are authorized to act on behalf of the rights holder; and (f) your physical or electronic signature. We may remove allegedly infringing material and terminate repeat infringers.

17. Export Compliance and Sanctions

You agree to comply with all applicable export-control and sanctions laws and regulations. You represent that you are not located in, and will not use the Service in or for the benefit of, any country or party subject to applicable embargoes or sanctions, and that you are not on any restricted-party or denied-party list. You may not use the Service for any purpose prohibited by such laws.

18. Force Majeure

Tethry will not be liable for any delay or failure to perform resulting from causes beyond our reasonable control, including acts of God, natural disasters, war, terrorism, civil unrest, labor disputes, governmental action, internet or telecommunications failures, power outages, denial-of-service attacks, or failures of third-party providers.

19. Severability

If any provision of these Terms is held invalid, illegal, or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or if it cannot be so modified, severed, and the remaining provisions will continue in full force and effect.

20. Waiver and Assignment

Our failure to enforce any provision of these Terms is not a waiver of our right to do so later. You may not assign or transfer these Terms or your account without our prior written consent. We may freely assign these Terms, including in connection with a merger, acquisition, or sale of assets. Any attempted assignment in violation of this Section is void.

21. Entire Agreement

These Terms, together with our Privacy Policy and any additional terms you agree to, constitute the entire agreement between you and Tethry regarding the Service and supersede all prior or contemporaneous agreements, understandings, and communications, whether written or oral, regarding the Service.
