Date of Last Revision: 12/27/2025

1. Introduction

Welcome to Tangra! These Terms of Service ("Terms") form a binding agreement between you and Simply Flows LLC, doing business as/with alternate names of Tangra and Tangra AI ("Tangra", "Tangra AI", "Company", "We", "Us", "Our"). These Terms apply to the tangra.link website, any related websites, mobile applications, software tools, AI models, and all features, content, and functionality we provide (collectively, the "Services").
By accessing or using the Services, you agree to be bound by these Terms. If you do not understand or accept these Terms, you may not use the Services.
If you use the Services on behalf of an organization, "You" includes both you and that entity, and you confirm that you are authorized to bind that entity to these Terms.

2. Definitions

For clarity:

"Input" means any data you provide, including prompts, text, images, audio, video, voice samples, or other materials.
"Output" or "AI-Generated Content" means any content generated by the Services, including images, videos, music, songs, voices, text, or chat responses.
"User Content" means Input and any other content you upload or submit (e.g., text, images, photos, audio, video, etc.).
"Models" means Tangra's proprietary AI systems used to generate Output.
"Services" means all Tangra websites, apps, tools, models, features, and content.

Tangra may update, modify, or discontinue any part of the Services at any time.

4. Eligibility and Accounts

You must be at least 18 years old to use the Services. You are responsible for maintaining the confidentiality of your account and all activity under it.

5. User Content (Inputs and Uploads)

You retain ownership of your User Content. By submitting User Content, you grant Tangra a worldwide, non-exclusive, royalty-free license to use, reproduce, process, and display your content as necessary to provide and improve the Services. You confirm that:

You have all rights and permissions to upload and use the content.
You will not upload copyrighted material without permission.
You will not upload images, videos, or voices of real individuals without their consent.
You will not upload personal data of others without authorization.

Tangra may remove or restrict User Content that violates these Terms.

6. AI-Generated Content (Outputs)

Tangra may provide you with Output generated by AI Models based on your Input.

6.1 Ownership and License

To the extent permitted by law:

Tangra grants you a broad, worldwide, royalty-free license to use, reproduce, modify, publish, and commercialize Output.
Output may be considered public domain under US law, and Tangra makes no guarantee that Output is copyrightable.

6.2 Copyright Status

AI-generated content created through Tangra may not qualify for copyright protection under current US and international copyright laws. Copyright generally requires human authorship, and content generated solely by an artificial intelligence system may be considered non-copyrightable or public domain. What this means for you:

You may freely use, reproduce, modify, publish, and commercialize the AI-generated content you create with Tangra.
You do not owe Tangra any royalties or fees for using the Output.
You may not be able to claim exclusive copyright ownership over AI-generated content because it may lack the human authorship required for copyright protection.
Other users may generate similar or identical content, and you may not be able to prevent others from using similar outputs.
If you combine AI-generated content with your own original creative contributions, the human-authored portions may be copyrightable, but the AI-generated portions may not be.

Copyright law is evolving, and interpretations may change. Users are responsible for ensuring that their use of AI-generated content complies with applicable laws.

Marketing (unless you opt out)

Create harmful or deceptive deepfakes
Clone voices without consent
Generate political persuasion content
Replicate copyrighted songs, lyrics, or performances

A statement that the information in your notice is accurate, and that you are the copyright owner or authorized to act on the copyright owner's behalf, made under penalty of perjury

12. Disclaimers

The Services and Output are provided "as is", with no guarantees on accuracy, availability, or suitability. Tangra does not guarantee that the Services will always function as intended. The Output of our Services may contain errors, inaccuracies, or incomplete information.
Features may be added, removed, or adjusted at our discretion. Nothing on this website or produced by our Services should be considered legal or professional advice. Your use of the Services is entirely at your own risk.
Access to certain areas of the website and Services may be restricted. We may limit access at our discretion.
AI Content is automated and based on patterns recognized in the training data. They do not reflect the views or opinions of Tangra's developers or owners. Users are responsible for reviewing, verifying, and using the generated content in a manner compliant with applicable laws and regulations.

13. Limitation of Liability

Tangra shall not be liable for indirect, incidental, special, or consequential damages arising from the use of its Services, including but not limited to loss of profits, data, or goodwill. Tangra's total liability under these Terms shall not exceed the amount paid by the user for the Services in the twelve months preceding the claim.

14. Indemnification

By using our Services, you agree to indemnify, defend, and hold harmless Tangra, its affiliates, officers, directors, and employees from any claims, damages, liabilities, or expenses arising out of user's misuse of Tangra's Services, violation of these Terms, or infringement of third-party rights through generated or uploaded content.

15. Arbitration and Class Action Waiver

All disputes must be resolved through binding arbitration on an individual basis. Class actions and jury trials are waived.
Please read this section carefully, as it affects your legal rights. By agreeing to these Terms, you and Tangra are agreeing to resolve most disputes through mandatory, binding arbitration rather than in court, and you are giving up your right to a jury trial or to participate in a class action.
Informal Resolution First: Before either you or Tangra initiates arbitration or any other formal dispute process, both parties agree to first attempt to resolve the issue informally. The party raising the dispute must contact the other and make a good faith effort to resolve the matter. The receiving party will have 30 days to respond. This informal process is a required first step and must be completed before arbitration may be initiated.
Agreement to Arbitrate; Class Action Waiver: If a dispute, claim, or controversy ("Claim") remains unresolved after the informal process, it will be settled through final and binding arbitration. This includes any Claim relating to your use of Tangra's Services, any AI-generated output, or your inability to access or use the Services.
Arbitration forum. If we are unable to resolve the Dispute, either of us may commence arbitration with National Arbitration and Mediation ("NAM") under its Comprehensive Dispute Resolution Rules and Procedures and/or Supplemental Rules for Mass Arbitration Filings. Tangra will not seek attorneys' fees and costs in arbitration unless the arbitrator determines that your claim is frivolous. The activities described in these Terms involve interstate commerce and the Federal Arbitration Act will govern the interpretation and enforcement of these arbitration terms and any arbitration.
Arbitration procedures. Arbitration will be conducted by videoconference whenever reasonably possible. If the arbitrator determines that an in-person hearing is necessary, the location will be mutually agreed upon, held in the county where you reside, or set by the arbitrator, unless a batch-arbitration process applies. The proceeding will be overseen by a single arbitrator, who will be either a retired judge or an attorney licensed to practice law in New Jersey, USA.
The arbitrator has exclusive authority to resolve any Dispute. Neither party may disclose any settlement offer to the arbitrator until after the arbitrator issues a final award, if one is made. The arbitrator may grant motions that dispose of all or part of a Dispute.
Class Action Waiver. To the fullest extent permitted by law, you and Tangra agree that any dispute must be brought only in your or Tangra's individual capacity, and not as part of any class, consolidated, collective, or representative action.
You and Tangra waive any right to participate as a plaintiff or class member in any class action. The arbitrator has no authority to combine claims, conduct a class arbitration, or award relief to anyone who is not a party to the arbitration.
If a court determines that this class action waiver is unenforceable for a particular Claim, then the agreement to arbitrate does not apply to that Claim, and it must proceed in court. All other Claims will remain subject to arbitration.

16. Modification of Terms

We may change these Terms at any time. Updates will be effective immediately upon posting. Continued use of the Services after updates constitutes acceptance of the revised Terms.

17. Severability

If any term is found to be unenforceable, the rest of the Terms remain valid.

18. Assignment

Tangra may assign, transfer, or delegate its rights and obligations under these Terms, in whole or in part, without notice. You may not assign or transfer any rights or obligations under these Terms without Tangra's prior written consent.

19. Entire Agreement

These Terms form the entire agreement between Tangra and you regarding our Services.

20. User Feedback

We welcome your feedback to help improve our Services. By providing feedback, you agree that we may use it without restriction or compensation to you.

21. Usage Restrictions

Users agree not to reverse-engineer, decompile, or attempt to extract Tangra's source code or models; scrape, overload, or misuse Tangra's systems; circumvent access controls or security features; or use Tangra's Services in ways that interfere with other users or the platform's integrity.

22. Fair Usage Policy - Ultimate Plan

The Ultimate Plan provides unlimited access for professional users, subject to this Fair Usage Policy. To ensure reliable and high-quality Services for all customers, Tangra monitors usage to prevent activity that places an unreasonable load on our infrastructure or impacts platform stability.
"Fair usage" refers to the activity levels and consumption patterns of at least 95% of Ultimate Plan users. The Ultimate Plan is designed for normal professional and creative use and is not intended for automated systems, large-scale data processing, reselling, or other atypical workloads that could cause disproportionate strain on our systems.
Tangra may take reasonable measures, such as temporarily throttling usage, applying rate limits, or offering an alternative plan, if account activity significantly exceeds what is considered typical or results in infrastructure or API costs that are materially higher than the plan's value.

23. Governing Law and Jurisdiction

These Terms are governed by the laws of the United States of America and the State of New Jersey. Disputes will be handled in state and federal courts located in New Jersey.

24. Privacy

Please review our Privacy Policy for details on data handling.
