Contact IndexTTS Online

The primary public contact for IndexTTS Online is support@indextts.online. Use this address for product support, billing, privacy, account, copyright, safety, abuse, security, and legal-notice questions relating to indextts.online.

Product and account support

For generation errors, account access, Saved Voices, History, model selection, Voice Pack balance, or Pro-plan questions, include the email address associated with your account when appropriate, the approximate time of the issue, the page you were using, and a short description of what happened. Do not send passwords, full payment-card numbers, authentication tokens, or other secrets.

Billing and purchase questions

For a one-time Voice Pack or Pro subscription issue, include the account email, approximate purchase time, product purchased, and any non-sensitive order reference shown by the checkout provider. Payment processing is handled through an external checkout provider, so we may need to compare your report with provider-side order status before confirming an entitlement issue.

Never email a full card number, CVV, online-banking password, or identity-document image for ordinary billing support. Those details are not required to investigate a normal entitlement or order-status problem.

Privacy and data requests

You can use the same support address for requests concerning access, correction, deletion, or other privacy rights that may apply in your jurisdiction. To protect account data, we may need to verify that the requester controls the relevant account before acting on a request.

If your request concerns a specific Saved Voice, generation, or uploaded reference, identify the account and relevant approximate date rather than attaching additional sensitive audio unless we ask for it.

Unauthorized voice cloning or impersonation reports

If you believe a voice has been uploaded or cloned without permission, or synthetic speech is being used to impersonate someone deceptively, contact us with enough information to investigate. Useful details include the relevant public URL, the person whose voice or identity is affected, why the use appears unauthorized, and any context showing how the output is being presented.

Please do not submit fraudulent reports or attempt to obtain another user's private generation data. We review reports in the context of our Acceptable Use Policy, privacy obligations, and the information available to us.

Copyright and other rights concerns

If a page or publicly accessible asset on indextts.online infringes rights you control, identify the material, the right you believe is affected, your relationship to the rightsholder, and a reliable way to contact you. Clear, specific notices can be investigated more efficiently than broad requests with no URL or work identified.

Security reports

For suspected security vulnerabilities, send a concise description, affected URL or feature, reproducible steps, and the potential impact. Do not exploit a vulnerability beyond what is necessary to demonstrate it, access other users' data, or disrupt the service. Marking the subject line with “Security” helps route the report.

Business and media inquiries

Product partnerships, responsible research questions, and media inquiries may also be sent to the support address. Please state the organization, purpose of the inquiry, and the specific information requested. IndexTTS Online is an independent hosted service and is not the official IndexTTS research team, so questions about upstream model research itself may be better directed to the original model authors.

Legal notices

Formal notices relating to the operation of indextts.online may be sent electronically to support@indextts.online. If a matter requires verified operator details, identity verification, or another delivery method under applicable law, state that requirement clearly so the appropriate information can be handled through a verified channel.

What to expect

We prioritize account access, payment-entitlement failures, credible safety reports, privacy requests, and security issues. Response time can vary with complexity and verification needs. Sending one complete message is usually faster than sending several partial messages about the same issue.
