Terms of Use

Version of 2026-11-12 · The German version is binding.

These terms apply to the use of Sprachfuchs. By registering and continuing to use the service, you agree to them. The provider of Sprachfuchs and contractual partner for use of the service is Nils Niemann, c/o MDC#dev, Welserstraße 3, 87463 Dietmannsried, Deutschland (referred to below as “we”). Contact: support@sprachfuchs.com.

1. What Sprachfuchs is

Sprachfuchs is a practice service for preparing for German examinations (reading, listening, writing, speaking, pronunciation, mistake training and community). Sprachfuchs is not an examination institute and is not affiliated with the Goethe-Institut, ÖSD or telc. The names of these examinations are mentioned only to describe what the exercises prepare you for.

2. Registration and account

• Sprachfuchs is for people aged 18 or over. By registering, you confirm that you are at least 18.
• Registration is open. You need a valid email address and your details must be accurate. Invitation codes that we issue privately may additionally grant a plan (section 3). While registration is closed, a code is required.
• The account is personal. Do not disclose your password or share your account. We may suspend accounts that are clearly used by several people. You are responsible for everything done through your account if you have disclosed your password.
• Choose a password that you do not use anywhere else and tell us if you notice misuse.

3. Service, plans and price

Free access. With a free account, you choose a level and examination provider and receive one practice examination including AI evaluation (reading, listening, writing and speaking). You also receive the functions marked as free in the app, such as mistake training. Limits for AI-evaluated modules (writing and speaking) are shown in the app. Free access costs nothing and does not renew automatically.

Plus. Plus gives you access to all released practice examinations and AI evaluations without a fixed limit. To protect against misuse, a technical limit of 10 examinations per day applies (writing and speaking count towards it); ordinary use is rarely affected. Plus costs €9.00 per month including statutory VAT at launch. The price is shown in the app before purchase; the price shown during the order process is authoritative. Plus can be purchased from the time at which we enable payment in the app.

Contract and payment. Our online retailer Paddle.com handles the Plus order process. Paddle.com Market Limited (“Paddle”) is the Merchant of Record and seller for all Plus orders. Paddle collects the price, issues the invoice, accounts for VAT and answers questions about payment, invoices and refunds. Paddle’s buyer terms, shown during checkout, also apply. We provide access to and the content and functions of Plus. The available payment methods are shown before you order. The contract is concluded when you complete the order process. While Plus is not yet available for purchase (see above), there is no purchase or payment.

Term and renewal. Plus runs for one month and renews for another month unless you cancel. You may cancel at the end of the current month (section 8). You keep access until then.

Price changes. We change the price of Plus only for future periods and only with your express consent. We announce the change in the app and by email at least six weeks before the new period begins and ask for your consent. Silence does not count as consent. If you do not consent, the previous price remains valid until the end of the current period; Plus then ends if we ordinarily terminate the contract at that time. You may independently cancel at any time at the end of the current month.

Granted access. Invitation codes that we issue privately and access that we set up manually are not paid contracts. They end at the stated time without requiring cancellation and never automatically become a paid subscription.

Changes to the service. We may change, extend or discontinue functions and adjust free access. During current Plus periods, we will not reduce the service to your disadvantage except for an important reason. We aim to operate the service reliably but do not promise uninterrupted availability.

3a. Right of withdrawal

As a consumer, you have a 14-day right of withdrawal for a paid Plus contract, and on request we refund the price within these 14 days without giving reasons and without deduction. The notice, model withdrawal form, refund rule and consequences are set out in Withdrawal and refunds. That page also contains the “Withdraw contract” function (after signing in) and explains how to request a refund from Paddle.

If Plus starts before the withdrawal period ends at your express request, you confirm this during checkout.

4. AI and practice evaluation

Evaluations of writing and speaking, the conversation partner and speech output are produced by artificial intelligence. They are a practice estimate, not an official examination. They may contain errors and say nothing about how an examination institute would actually assess you. We do not guarantee that you will pass an examination with a particular result. The Privacy Notice explains which data is sent to AI providers.

5. Your duties and permitted use

• Use Sprachfuchs only for your own learning and in accordance with the law.
• You must not disrupt, overload, scrape, crawl or misuse the platform, bypass security measures or attempt to access other people’s accounts or data.
• You must not copy, distribute, publish or use content (examinations, texts, audio, images and evaluations) to train other AI systems. Content created by us is protected by copyright where applicable. You may use it for your own learning and print extracts for private use.
• Do not write or say anything in exercises that infringes another person’s rights, and do not enter third-party data.

6. Community

The community is optional and for adults only. Insults, harassment, spam and unlawful or inappropriate content are prohibited. We may remove content and suspend community access or the whole account if you breach these rules. Messages are encrypted on the server but not end-to-end encrypted; see the Privacy Notice. You are responsible for content you send.

7. Your content

Your answers, texts, voice recordings and messages remain yours. You grant us the right to store and process them and to transmit them to the service providers named in the Privacy Notice where necessary to provide the service (evaluation, mistake profile and community). We do not use them for other purposes unless you expressly consent.

8. Suspension and termination

Cancelling Plus. You can end a Plus subscription at any time using “Cancel contracts here”. It is available at /kuendigen and in the “Me” menu, even without signing in. Cancellation takes effect at the end of the current month. We confirm receipt with the date and time by email. The right to terminate for good cause remains unaffected.

You may delete your account at any time in the “Me” menu. If you have an ongoing paid Plus subscription, we cancel it when the current period ends; amounts already paid are refunded within the 14 days under section 3a and thereafter where required by law. We may suspend or delete accounts if you breach these terms, misuse occurs or the service is discontinued; if the service is discontinued, we will give reasonable notice where possible. After deletion, your data is deleted according to the periods in the Privacy Notice.

9. Liability

We are fully liable for intent and gross negligence, for injury to life, body or health and under the Product Liability Act. For a slightly negligent breach of a material contractual duty (a duty you may rely on and without which the contract could not be performed), our liability is limited to foreseeable, typical loss. Otherwise, we are not liable for slight negligence. Mandatory statutory rights remain unaffected.

10. Changes

We may change these terms for the future where an objective reason requires it (law, new functions or misuse). We announce changes in the app and by email at least six weeks before they take effect. A change affecting the service, price or your duties applies only if you expressly consent. Silence does not count as consent. If you do not consent, the previous terms continue to apply; we may then ordinarily terminate the contract, for Plus at the end of the current period. Purely editorial changes (such as typographical errors or clarifications without substantive effect) and changes that only benefit you may be announced and implemented without consent.

11. Contact

Questions about your account, Plus, cancellation, withdrawal, refunds or these terms: support@sprachfuchs.com. We usually reply within a few working days. Paddle also answers questions about payment and invoices at paddle.net.

12. Final provisions

German law applies; mandatory consumer-protection rules of the country in which you live remain unaffected. If a provision is invalid, the remainder remains effective. Regarding EU online dispute resolution, the former platform has been discontinued. We are not willing or obliged to participate in dispute-resolution proceedings before a consumer arbitration board.
