Terms of service

These terms apply to the use of B1 Sprechen (b1sprechen.com). The provider is Tianshu Labs LLC, a limited liability company organized under the laws of the State of Wyoming, USA (address: 30 N Gould St, Ste N, Sheridan, WY 82801, USA). You can reach us at support@b1sprechen.com; further details are in the legal notice.

B1 Sprechen is a practice simulation of the speaking part of the Goethe-Zertifikat B1 and of telc Deutsch B1: preparation, the three parts of the exam and individual feedback. The examiners and your partner are voiced by AI; for the conversation and the feedback we use AI models from external providers (currently OpenAI). More in the AI notice.

Every simulation is recorded so that you can listen to it later. Details are in the privacy policy.

B1 Sprechen is an independent practice service and is not affiliated with the Goethe-Institut or telc gGmbH. The simulation does not replace the official exam and issues neither a certificate nor a grade. Your exam result depends on your performance on the day of the exam.

• To open an account, you must be at least 18 years old and confirm your email address.
• Please use one account per person and keep your sign-in details to yourself.
• If we offer a free test (you will then see it on the website and in “My area”), you can use it once per person after confirming your email address: one part of the exam (planning something together) with feedback on that part. Further accounts or disposable addresses for more tests are not allowed. There is no entitlement to the test: we may change or end the offer at any time and limit the number of tests per day.

• You buy simulations as a pack with a one-off payment – not a subscription. Current prices are on the pricing page.
• Payment is handled by our payment provider Stripe. Your payment receipt is available on the orders page.
• After payment, your simulations are available at once and valid for 90 days. We always use the simulation that expires first.
• Starting a simulation uses one simulation from your balance. If you end it before part 1 (for example during the preparation) or in the first 30 seconds of part 1, you get it back automatically. If it breaks off because of a technical error on our side, or the feedback cannot be created, we credit it back to you after review.
• Within 14 days of purchase, we refund unused simulations pro rata. Details are in the refund policy.

• The simulation is meant for your own practice.
• Please no automated access, no sharing of your account, no attempts to get around security measures and no unlawful or offensive content.
• What you say in the simulation is practice content and does not change how it runs.
• In case of serious misuse, we may block an account.

• We work to keep the service reliable, but we cannot guarantee that it is available at all times without interruption. AI feedback may contain errors.
• To the extent permitted by law, our liability is limited to the amount you paid for the service in the last 12 months. Mandatory statutory rights, for example as a consumer, remain unaffected.
• The law of the provider's place of business (Wyoming, USA) applies; mandatory consumer protection rules of your country of residence remain unaffected.
• These terms are available in German, English and Chinese; if they differ, the German version prevails.
• We may update these terms. A purchase is governed by the version you agreed to when you made it (currently 2026-11-10).
