This policy explains how this site (an AI voice studio: text to speech, AI voice changing, sound effects, video dubbing, transcription and more) handles your personal data. The site is run by Aaron, an independent developer, who also receives its payments. By using the site you confirm you have read and understood this policy.

1. What we collect
What you give us
- Account details: email address, password (stored with one-way hashing), display name. If you sign in with Google, we receive the email, name and picture Google provides.
- What you submit: text to be voiced, audio and video you upload, voice design descriptions, pronunciation dictionary rules, support tickets.
- Payment details: order amount, order number, payment status. We never see or store your full card number, payment password or ID number; payment providers handle those directly.
What is collected automatically
- Usage data: pages visited, features used, number of generations and characters, credit history.
- Device and logs: IP address, browser and operating system, time of visit, error logs.
- Cookies and local storage: to keep you signed in, remember your language, keep an unfinished draft, and a randomly generated visitor ID (no personal data; it ties visits from one browser together so we can improve the product). You can clear or block cookies in your browser, but signing in will then not work.
2. How we use it
- To provide speech generation, voice changing, voice cloning and design, transcription, video dubbing and the other tools;
- To create and maintain your account and track your credits;
- To process orders, issue receipts and handle refunds;
- To check content for safety before generating it, and to prevent fraud, abuse and automated scripts;
- To send account email (verification, password reset) and usage reminders (you can unsubscribe at any time);
- To fix problems and improve the product;
- To cooperate with regulators or courts where the law requires it.
We do not sell your personal data to anyone.
Your text and your work: we do not use the text you submit, the audio you upload or what you generate to train any model, and we never put it on a public page. To generate it, the text and audio are sent to the third-party providers that do the processing for us (section 3).
3. Who we share it with
To provide the features above, the site shares the minimum necessary data with these providers:
| Provider | Purpose | Data involved | Location |
|---|---|---|---|
| ElevenLabs | Speech, multi-speaker dialogue, voice cloning and design, voice changing, voice isolation, transcription, video dubbing, sound effects and music | Text you submit, audio and video you upload | United States |
| The language-model provider used for content checks | Checking text for prohibited content before generating it | Text you submit | To be confirmed |
| Replicate | Vocal / instrumental separation (only when you use that tool) | Audio you upload | United States |
| Stripe | Card payments, refunds, subscriptions | Order number, amount, payment status, billing email | United States |

4. International transfers
The speech, separation, card payment, email and analytics providers above are outside mainland China. This means:
- the text, audio and video you submit are sent to servers abroad for processing;
- generated audio may be stored abroad;
- usage data may be collected by analytics services abroad.
By using the site you acknowledge and agree to these transfers. If you do not, please do not use the generation features. Do not upload content that involves state secrets, important data or large amounts of sensitive personal data.
5. How long we keep it
- Account details: for as long as the account exists;
- Orders and credit history: 5 years from the transaction (accounting and tax rules);
- Generation records (who generated what, when): at least 6 months, as required;
- Generated audio: until you delete it, or 30 days after the account is closed;
- Server logs: usually no more than 90 days.
6. Your rights
You can at any time:
- see and correct your account details (in your account settings);
- delete what you have generated;
- close your account: the personal data linked to it is deleted or anonymised, except transaction records we must keep by law;
- withdraw consent by no longer using the feature concerned; unsubscribe from reminder emails with the link at the bottom of each;
- get a copy of your data or object to how it is processed.
To exercise these rights, email support@vocaltwist.online; we reply within 15 business days.
7. Security
We protect your data with encrypted transport (HTTPS), one-way password hashing, encrypted storage of service keys and access controls. Still, no transmission or storage on the internet is completely secure. Keep your password safe and do not share it.
If personal data is ever leaked, we will tell the users affected and report it to the regulator as the law requires.
8. Children
The site is not intended for children under 14. If you are under 18, use it with a parent or guardian's consent and guidance. If we find we have collected a child's personal data without knowing, we delete it promptly.
9. Changes to this policy
We may update this policy as features or laws change. Significant changes will be announced on the site or by email. The date at the top shows the latest revision.
