Last updated: 10 November 2026
These terms apply to the Rufa website, the Rufa Arena and the Rufa playgrounds (together, the "service"), provided by Rufa Labs, Luxembourg ("Rufa", "we"). By creating an account or using the service you agree to them.
The service
Rufa offers speech-to-text, text-to-speech, translation and language models, and the Rufa Arena, where you can try and compare them. The Arena is a demonstration and evaluation environment: features change, models are updated, and the service may be paused or unavailable at times.
Results are produced automatically and can contain mistakes. Check important transcripts, translations and summaries before you rely on them.
Your account
You need to be 18 or older to create an account. You sign in with a one-time code sent to your email, or with a passkey you added. Keep access to your email and devices secure: anyone who can read your sign-in codes can use your account.
Your email address identifies your account and cannot be changed. You can edit your name and company in your profile. To close your account, write to us at EMAIL.
What you may do
Use the service for lawful purposes and in line with these terms. Do not upload content you have no right to use, try to break or overload the service, get around its limits, or use it to build a competing product from our outputs.
Only record or upload your own voice, or the voice of someone who has agreed to it. Voice cloning is only allowed with your own voice or with the recorded consent of the person whose voice it is. Never use a Rufa voice to deceive, impersonate a real person, or commit fraud.
Your content
You keep the rights to the recordings, texts and files you provide. You give Rufa the right to store and process them to run the service, and, as described in the consent text you accept, to evaluate and improve our models.
Generated audio, transcripts and translations from the Arena may be used by you for evaluation and internal purposes. Commercial use of Rufa models goes through an agreement with us.
Library voices
The voices in the Rufa library are demo voices that do not represent real people. Part of the library is built from openly licensed speech collections, credited on our Data & licences page.
Our responsibility
The service is provided "as is", without guarantees of availability or accuracy. To the extent the law allows, Rufa is not liable for indirect damage or for decisions taken on the basis of automatic results. Nothing in these terms limits rights you have as a consumer under Luxembourg or EU law.
Changes and ending
We may change these terms. When we do, we ask you to accept the new version the next time you sign in. We may suspend accounts that break these terms.
These terms are governed by Luxembourg law. Courts in Luxembourg have jurisdiction, without prejudice to your rights as a consumer.
