Terms of Service
These terms apply to your use of Satzprofi (this website). By creating an account or subscribing you agree to them. Contact: appsatzbau@gmail.com.
The service
Satzprofi helps you practise German grammar, vocabulary, speaking and writing. Feedback, corrections, exercises and explanations are generated by artificial intelligence. They are usually correct but can contain mistakes; use them as learning help, not as authoritative or professional advice.
Your account
- You must give a valid email address and keep your login details private.
- You are responsible for activity on your account.
- You must be at least 16 years old.
Subscription and payment
- Satzprofi has a free plan and two paid plans. Free: 15 ready-made sentences and 3 gap texts a day, without AI features. Premium (€19.99 a month): AI features with up to 80 AI actions a day and feedback on texts of up to 300 words. Intensive (€49.99 a month): up to 200 AI actions a day, feedback on texts of up to 600 words, exam-style practice and priority support. Checking a sentence counts as one AI action, a new gap text as two, and feedback on a text as one per started 100 words. Library and built-in exercises don't count. Prices include VAT and are shown before you pay. Exam practice follows the published format of the Goethe, telc and ÖSD exams; Satzprofi is not affiliated with these exam providers, and practice scores are estimates, not official results.
- Our order process is conducted by our online reseller. Card and other non-crypto payments are processed by Dodo Payments, which is the Merchant of Record for these orders; Dodo Payments provides customer service for payment inquiries and handles returns. Crypto payments are processed by Suby on its own checkout page and under its terms.
- Premium and Intensive are monthly subscriptions. They renew every month until cancelled. You can switch plans in the app: an upgrade paid by card applies at once, with the price difference for the current period; a downgrade applies at your next renewal. You can cancel at any time in the app under Account → Cancel subscription; you keep access until the end of the period you have paid for.
- You can get a full refund within 14 days of your first payment. Details are in our Refund Policy.
- We may change prices for future periods and will tell you in advance.
Fair use
Each account has a daily limit on AI actions, and the free plan's daily exercises are counted per account and per internet connection. Creating several accounts to get around these limits is not allowed. You may not misuse the service, for example by trying to access other users' data, overloading it, reselling access, sharing your account, or submitting illegal content.
Your content
You keep the rights to the texts you write. You allow us to process them to provide the service, as described in the Privacy Policy.
Availability and liability
We aim to keep Satzprofi available but cannot guarantee it will always work without interruption or errors. To the extent the law allows, we are not liable for indirect losses, and our total liability is limited to the amount you paid in the last three months. Nothing in these terms limits rights you have under mandatory consumer law.
Ending your account
You can delete your account at any time in the app. We may suspend accounts that seriously or repeatedly break these terms.
Changes
We may update these terms. If changes are significant we will tell you before they apply; continuing to use Satzprofi after that means you accept them.
