These terms apply to everyone who uses Metaphona. By signing in, you accept them for yourself and for the organization your account belongs to.
The service
Metaphona turns a video in one language into the same video dubbed in another. It writes down the speech, translates it line by line, makes the new voices, fits them to the timing, mixes them with the original music and sounds, and gives you the dubbed video to download.
Metaphona is provided by [Operator: company name, legal form and registered address].
Accounts and organizations
Every account belongs to one organization. Accounts are created by invitation from the organization, or when we approve a request for access.
The organization’s owner decides who joins and with which role (owner, manager, editor or viewer), and is responsible for the people they invite.
- Keep your password to yourself and choose one of at least 12 characters.
- Do not share an account between several people.
- Tell us at once if you think someone else has used your account.
Trials, plans and payment
A trial gives a number of free minutes in total and a maximum video length. No payment card is asked for.
A plan sets the minutes included each month, the storage space and the longest video. Minutes are counted when a video’s processing starts, and again each time its translation is redone.
We send invoices for plans and for extra minutes. They are paid by bank transfer or mobile money, following the instructions printed on the invoice; no card payment is taken online. An invoice is not changed once it is sent: a mistake is corrected with a credit note.
When an invoice remains unpaid well after its due date, new videos are paused until it is paid. Videos already dubbed can still be downloaded.
Acceptable use
Upload only videos you have the right to use and to have dubbed. You must not use the service to:
- impersonate a person in a way that deceives, or make someone appear to say what they did not say;
- fabricate an endorsement, a testimony or a statement and attribute it to a real person;
- clone a voice from media your organization has no rights to, such as public clips, recordings of celebrities or other people’s media;
- present a video with cloned voices as the speakers’ own recording in the new language;
- publish content that is illegal, that infringes someone else’s rights, or that harasses or harms people;
- try to get around security, quotas or another organization’s isolation, or to overload the service.
Your content and your rights
Your videos, transcripts, translations and dubbed videos remain yours. You give us only the permission we need to store and process them to provide the service to your organization.
You are responsible for holding the rights to what you upload, including the rights of the people who appear and speak in it. We do not use your videos, voices or texts to train models.
AI output and your review
Transcription, translation and the new voices are made by AI models. They can make mistakes: a misheard word, a translation that misses the meaning, a mispronounced name or a line that does not fit its time.
Metaphona gives you the tools to check: you review the transcript and the translation before the voices are made, every cloned take is heard again by speech recognition, and any line can be corrected on its own. Review the result before you publish it; you are responsible for what you publish.
Availability
We work to keep the service available and your work safe, but this draft promises no guaranteed availability. The service may be interrupted for maintenance or updates, and long videos may take hours to process.
We make a backup every night, but keep your own copy of your original videos: our backups protect against mistakes, not against every possible loss.
Suspension and ending
We may suspend an account or an organization that breaks these terms, puts other people at risk or leaves invoices unpaid. When we can, we tell the organization’s owner first.
The owner of a project can delete it at any time: its videos, records and files are deleted and cannot be restored. To close the organization, write to us.
Liability
[Operator: limitation of liability, to be written with the lawyer.]
Changes, applicable law and contact
We may update these terms. The date at the top of this page shows the latest version; important changes are announced in the app and may also be sent by email.
[Operator: applicable law and competent courts.]
