Terms of Service

Last updated: October 6, 2026

Tangara is operated by Konstantin Potapov, an individual based in Mexico, with a correspondence address at Muluk MZA 3 LT 18 INT D 8A, Quintana Roo ("Tangara", "we", "us"). Contact: [email protected].

These Terms cover tangara.app, docs.tangara.app, the Tangara REST API and MCP server (the "Service"). By creating an account or using the Service, you accept these Terms and the Acceptable Use Policy. The Billing & Refund Policy explains payment terms. The Privacy Policy explains how we handle personal data.

1. The Service

Tangara generates videos, images, music and speech using models running on rented GPU servers. Available settings and prices appear in the product and API documentation. Your account history stores your tasks and results. Results are not automatically published in a public gallery.

Generation is probabilistic: outputs may be unexpected, inaccurate, similar to other outputs or unsuitable for your intended use. Review results before publishing or relying on them. Estimated completion times depend on capacity and are not guaranteed delivery times.

2. Accounts and access

You must be at least 18 and able to enter into this agreement. If you act for an organisation, you must have its authority. Provide an email address you control and protect your password, session and API key. Report suspected unauthorised access to [email protected].

Sign-in methods are those currently offered on the website. If Google sign-in is available and you choose it, we use your Google account identifier and email to authenticate you, as described in the Privacy Policy.

REST API and MCP requests use your account balance under the same pricing rules as the website. Connected apps and AI assistants can submit paid tasks with your key. Only give access to tools you trust, and revoke or replace a compromised key. Do not put a private key in public code or client-side applications.

3. Prices and prepaid balance

Tangara uses a prepaid balance in US dollars. A top-up is a one-time payment through Stripe, not a subscription. The checkout shows the total payment before you confirm it. Any applicable tax charged at checkout must be included in that displayed total.

A generation quote reflects the requested settings and the current tariff. The accepted price is recorded with the task and deducted when it enters the queue. Later tariff changes do not change the price of an accepted task. Insufficient balance prevents a paid task from being accepted.

A permanently failed task receives an automatic return to the Tangara balance. Card refunds and questions about completed results are handled under the Billing & Refund Policy. Generation completion is not a promise of a particular artistic result.

4. Your content and generated results

You retain the rights you have in your prompts and uploaded files. You must have the rights and permissions needed to process them and use the results, including permission for another person's likeness or voice where required.

You grant Tangara permission to store, copy, process and transmit your inputs and results to provide the Service, handle support and security issues, enforce our rules and meet legal obligations. This permission does not give us the right to sell your content or publish it as promotional material without your permission. Tangara does not use your inputs or results to train AI models.

As between you and Tangara, Tangara does not claim ownership of your generated results. You may use them for lawful personal and commercial purposes subject to these Terms, applicable model restrictions and third-party rights. We cannot guarantee that an output is unique, copyrightable or free of another person's rights.

Video generation uses LTX-2.5. Its LTX-2.x Community License, including Section 4 and Attachment A, imposes use restrictions that are incorporated into this agreement for LTX generation and outputs. See the Acceptable Use Policy. These Terms do not grant rights to the underlying model weights or override their licences.

5. Acceptable use and account restrictions

Follow the Acceptable Use Policy. Do not bypass billing, access controls or published limits, use stolen credentials, or interfere with other users or service availability. Using the documented API in your own application is permitted, subject to these Terms; keep your account credentials secure and ensure that people using your integration follow the applicable rules.

We may investigate reports, inspect relevant account and task records, restrict access or remove content to address a violation, a security threat or a legal requirement. Where reasonable and lawful, we will explain the reason and allow you to contact support for a review. We do not promise to detect every violation.

6. Closing an account

You can stop using Tangara at any time. Contact [email protected] to request account closure, deletion of personal data or a review of unused balance. Data deletion and retention are explained in the Privacy Policy; refunds are explained in the Billing & Refund Policy.

We may suspend or close an account for a serious or repeated breach, unauthorised payments, security concerns or a legal requirement. Suspension does not remove your statutory rights, including any right to a refund.

7. Availability and responsibility

We depend on hosting, storage, payment and GPU providers. Features and supported models may change, and interruptions can occur. Unless expressly agreed otherwise, we do not offer a service-level guarantee or guarantee that every request can be completed. Keep your own copies of results that matter to you.

To the extent permitted by law, the Service is supplied as available, without guarantees beyond those stated in these Terms or required by law. Nothing in these Terms excludes mandatory consumer protections, remedies for defective services or liability that cannot lawfully be excluded. Your legal rights take precedence over conflicting provisions of these Terms.

8. Changes and disputes

We publish updated Terms here with the update date. Material changes will be communicated through the Service or by email before they apply, unless an urgent legal or security requirement prevents advance notice. Changes do not retroactively alter accepted task prices.

Contact [email protected] about a concern or dispute. These Terms do not require mandatory arbitration or remove access to courts or consumer authorities available under applicable law. If a provision cannot be enforced, the remaining provisions continue to apply.
