Last updated: March 10, 2026

These Terms of Service ("Terms") are entered into between you and Tronor LLC ("Tronor," "we," "us," or "our"), and govern your access to and use of T-Sketch and any related websites, applications, and services (collectively, the "Service"). By accessing or using the Service, you agree to be bound by these Terms. If you are using the Service on behalf of an organization, you agree to these Terms on behalf of that organization and represent that you have the authority to do so.

If you do not agree to these Terms, do not use the Service.

ARBITRATION NOTICE: THESE TERMS CONTAIN A BINDING ARBITRATION CLAUSE AND A CLASS ACTION WAIVER IN SECTION 15. PLEASE READ THEM CAREFULLY. BY AGREEING TO THESE TERMS, YOU AGREE TO RESOLVE DISPUTES THROUGH INDIVIDUAL BINDING ARBITRATION AND WAIVE YOUR RIGHT TO PARTICIPATE IN CLASS ACTIONS.

1. Eligibility

You must be at least 13 years old to use the Service. If you are under 18, you must have a parent or legal guardian's permission. By using the Service, you represent that you meet these requirements.

2. Description of Service

T-Sketch is a web-based collaborative drawing and visual thinking application. The Service allows users to create, edit, and share visual content in real-time with others. We may add, change, or remove features of the Service at any time without notice.

3. Service Level

We target Service availability (uptime) of 99.5% or higher over each calendar month. Uptime is measured and reported by our uptime monitoring service at https://status.tronor.com. Scheduled maintenance and any downtime due to circumstances outside our reasonable control (for example, events that would fall under Force Majeure as described in Section 16) are excluded from this calculation and do not count against the 99.5% target.

4. User Accounts

To use certain features of the Service, you must create an account. You agree to:

  • Provide accurate and complete registration information
  • Maintain the security of your account credentials
  • Notify us immediately of any unauthorized use of your account
  • Accept responsibility for all activities that occur under your account

Account credentials are personal and may not be shared. We are not responsible for any loss or damage arising from your failure to protect your account credentials.

5. Subscriptions and Billing

The Service is offered under free and paid subscription plans. If you purchase a paid subscription:

  • Auto-Renewal. Your subscription will automatically renew at the end of each billing period (monthly or annual) at the then-current rate, unless you cancel before the renewal date.
  • Cancellation. You may cancel your subscription at any time through your account settings or by contacting us. Cancellation takes effect at the end of the current billing period. No refunds are provided for partial billing periods.
  • Price Changes. We may change subscription pricing at any time. Price changes for existing subscriptions take effect at the next renewal. We will provide reasonable notice of price changes.
  • Taxes. Subscription fees do not include taxes. You are responsible for any applicable taxes.
  • Payment. By purchasing a subscription, you authorize us (via our third-party payment processor) to charge the payment method you provide. You are responsible for any fees your bank or payment provider charges.

6. Acceptable Use

Your use of the Service is subject to our Acceptable Use Policy, which is incorporated into these Terms by reference. You agree to comply with the Acceptable Use Policy at all times. Violations may result in content removal, account suspension, or termination.

In addition to the Acceptable Use Policy, you agree not to:

  • Infringe upon the intellectual property rights of others (see our Copyright & DMCA Policy)
  • Reverse engineer, decompile, disassemble, or attempt to discover the source code of the Service
  • Resell, sublicense, rent, or redistribute access to the Service
  • Use automated means (bots, scrapers, etc.) to access the Service without our prior written consent

7. Intellectual Property

Your Content. You retain all rights to the content you create using the Service ("Your Content"). By using the Service, you grant us a limited, non-exclusive license to store, display, process, and transmit Your Content solely as necessary to provide and improve the Service.

Our Content. The Service, including its design, code, features, documentation, and all associated intellectual property, is owned by Tronor LLC. You may not copy, modify, or distribute any part of the Service without our express written permission.

Reservation of Rights. All rights not expressly granted in these Terms are reserved by the respective party. No license or right is implied by these Terms beyond what is expressly stated.

8. Feedback

If you provide us with suggestions, ideas, feature requests, comments, or other feedback about the Service ("Feedback"), that Feedback is not your intellectual property. You do not retain any ownership or other rights in it, and you have no claim against us for our use or implementation of it. You grant us an unrestricted, perpetual, irrevocable, royalty-free right to use, modify, and incorporate Feedback into our products and services. If we implement any Feedback, we have no obligation to you—including no obligation to pay you, credit you, or otherwise compensate you.

9. Usage Data

We collect and analyze data about how you use the Service ("Usage Data"), such as feature usage, performance metrics, and error logs. We may use Usage Data in de-identified and aggregated form to maintain, improve, and enhance the Service. Usage Data does not include Your Content itself.

10. Privacy

Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and protect your personal information.

11. Indemnification

You will indemnify, defend, and hold harmless Tronor LLC, its officers, employees, and contractors from any third-party claims, damages, losses, costs, and expenses (including reasonable attorney's fees) arising out of or related to: (a) Your Content; (b) your violation of these Terms; or (c) your violation of any applicable law or the rights of any third party.

12. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. WE MAKE NO WARRANTY REGARDING THE ACCURACY, RELIABILITY, OR COMPLETENESS OF ANY CONTENT AVAILABLE THROUGH THE SERVICE.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, TRONOR LLC, ITS OFFICERS, EMPLOYEES, AND CONTRACTORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SERVICE, REGARDLESS OF THE THEORY OF LIABILITY.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE TOTAL LIABILITY OF TRONOR LLC FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF: (A) THE AMOUNTS YOU PAID TO TRONOR IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM; OR (B) ONE HUNDRED DOLLARS ($100).

14. Termination

We reserve the right to suspend or terminate your access to the Service at any time, with or without cause, and with or without notice. Upon termination, your right to use the Service will immediately cease. We may delete Your Content within 30 days after termination. Sections 7 through 18 of these Terms survive termination.

15. Dispute Resolution

Binding Arbitration. Any dispute, claim, or controversy arising out of or relating to these Terms or the Service ("Claim") will be resolved by binding arbitration on an individual basis, rather than in court, except that either party may bring suit in court to enjoin infringement of intellectual property rights. The arbitration will be conducted by a nationally recognized arbitration provider under its applicable rules. The arbitration may be conducted remotely, in writing, or in San Francisco, California. The arbitrator's decision will be binding and enforceable in any court of competent jurisdiction.

Class Action Waiver. YOU AND TRONOR AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, CONSOLIDATED, OR REPRESENTATIVE ACTION. IF THIS WAIVER IS FOUND UNENFORCEABLE, THEN THE ENTIRETY OF THIS ARBITRATION PROVISION SHALL BE NULL AND VOID.

Opt-Out. You may opt out of this arbitration provision by sending written notice to support@tronor.com within 30 days of first agreeing to these Terms. Your notice must include your name, email address, and a clear statement that you are opting out of arbitration.

Pre-Arbitration Notice. Before initiating arbitration, you agree to send a written description of the Claim to support@tronor.com and allow 60 days for resolution.

16. General Provisions

Governing Law. These Terms are governed by the laws of the State of California, without regard to conflict of laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Jurisdiction. For any Claims not subject to arbitration, the exclusive jurisdiction and venue will be the state and federal courts located in San Francisco, California, and both parties consent to the jurisdiction of such courts.

Force Majeure. Tronor will not be liable for any delay or failure to perform resulting from causes outside its reasonable control, including but not limited to acts of nature, war, terrorism, epidemics, power outages, internet disruptions, or government actions.

Assignment. You may not assign or transfer these Terms or your rights under them without our prior written consent. We may assign these Terms without restriction. Any purported assignment in violation of this section is void.

Severability. If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect. The unenforceable provision will be modified to the minimum extent necessary to make it enforceable while preserving its intent.

No Partnership. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and Tronor.

Entire Agreement. These Terms, together with the Privacy Policy and any applicable subscription terms, constitute the entire agreement between you and Tronor regarding the Service and supersede all prior agreements.

Waiver. The failure of Tronor to enforce any right or provision of these Terms will not be deemed a waiver of that right or provision.

17. Changes to Terms

We may modify these Terms at any time. We will provide notice of material changes by posting the updated Terms on our website and updating the "Last updated" date. Your continued use of the Service after such changes constitutes acceptance of the modified Terms. If you do not agree to the changes, you should stop using the Service.
