Terms of Service

Last updated: 3 August 2026

1. Who we are, and what these terms cover

KorrektWort ("the Service", "we") is operated by Mohammad Mirzakhanidehkordi, Scharrnstraße 2, 38100 Braunschweig, Germany (contact@korrektcode.de). These terms govern your use of KorrektWort; you accept them when you create your account. Statutory consumer rights that cannot be waived by contract remain unaffected by everything below.

2. What KorrektWort is

KorrektWort is a personal, AI-assisted German vocabulary coach: you save words, the Service enriches them with AI-generated dictionary content (meaning, grammar, examples, translations), schedules reviews, and offers AI practice features. AI output is generated automatically and may contain mistakes: it is a learning aid, not professional translation, teaching, or advice; please verify AI output before relying on it for important decisions. We do not guarantee any particular learning outcome.

The Service also includes AI-generated grammar exercises and AI feedback on texts you write yourself. Exercises and their explanations are generated automatically and checked automatically before they are published in the app; despite that checking, an individual exercise or explanation may still be wrong. Feedback on your own writing is a learning aid, not proofreading or professional editing: please do not rely on it for documents that matter (for example job applications or letters to authorities) without also having them checked by a person. If an exercise or explanation looks wrong to you, please report it with the report button in the app. We review reports and remove content we have doubts about.

KorrektWort is independent. It is not affiliated with, endorsed by, or authorised by any examination board or language-certification body, and it is not an official preparation course for any specific examination. We do not guarantee that using the Service will lead to passing an examination or reaching a particular language level.

3. Your account and your content

• You need a Google account to sign in, and you must be at least 16 years old.
• Your account is personal and non-transferable. Keep access to it secure; you are responsible for activity through your account unless it results from a breach on our side. Tell us promptly at contact@korrektcode.de if you suspect unauthorized use.
• One account per person. You may not use the Service through automated scripts, resell access, or abuse the AI features (e.g. bulk extraction of generated content).
• You may only submit or paste content (e.g. texts for the reading feature, messages in practice conversations) that you are entitled to use and that is not unlawful or infringing on third-party rights. You are responsible for the content you submit; we may refuse to process content that violates this rule or the law.

4. Your words stay private

The vocabulary you save, your personal notes, your review progress, and your practice conversations are private to your account. Other users can never see which words you saved, your notes, or anything else about your learning. We do not sell your personal data. Details on data handling are in our Privacy Policy.

5. Content and ownership

• All rights in the Service (its software, design, brand, databases, and AI-generated dictionary content: definitions, example sentences, translations, grammar data, memory tips, stories, practice replies) belong to KorrektWort to the extent such rights exist, including our rights as database producer (§§87a ff. UrhG). Where AI-generated dictionary content for a word is language-general, we may reuse it to serve the same word to other users; this shared content never includes anything personal to you.
• Your own input (personal notes, texts you paste) remains yours. You grant us the licence needed to store and process it to provide the Service, including generating and maintaining shared, non-personal dictionary content for words; your notes, pasted texts, and learning data are never shared with other users.
• You receive a personal, non-exclusive, non-transferable right to use the Service and its content for your own language learning for as long as your account exists. You may not copy, scrape, systematically extract, or re-utilize the Service's content database or substantial parts of it, or make it available to third parties; this restriction survives the end of your account.

6. Credits and payments

• AI features consume credits. The credit cost of each feature is shown in the app before use; the cost shown at the time of use applies. Free monthly credits are a voluntary, revocable allowance with no monetary value. Purchased credit packs are prepaid usage credits for this Service only: non-transferable, with no cash payout during the contract; your statutory rights when the contract ends remain unaffected.
• Free credits are always used before purchased credits. Purchased credits do not expire for as long as your account exists. If you delete your account, remaining credits lapse, use or export first; statutory rights remain unaffected.
• We may adjust credit costs for good reason (e.g. changed AI-provider costs, changed features). Material increases will be announced in the app at least 30 days in advance; if you object, you may terminate and we will refund the unused portion of purchased credit packs pro rata at the price you paid.
• Payments are processed by Stripe; the contract for a credit pack is concluded when you complete payment in Stripe Checkout. Contract language is English; you can correct input errors at any time before clicking the payment button. Prices are total prices; as a small business under §19 UStG (Kleinunternehmerregelung), no VAT is shown or charged.
• To purchase credits you must be of full age or have the consent of your legal guardian.
• If a payment is reversed (e.g. an unjustified chargeback), we may remove the corresponding credits from your balance (if necessary resulting in a negative balance) and suspend paid features until the matter is resolved. We may pass on reversal fees actually incurred where you are responsible for the reversal.
• Invite and school bonuses. Credits granted through invite links, school/partner codes, or promotions are free credits (voluntary, revocable, no monetary value). We may change or end these programs for the future at any time and may withhold or reverse bonuses obtained through abuse (e.g. fake or duplicate accounts, self-referral). If you join through a school or partner code, that partner sees only aggregated, non-identifying statistics about the group that joined through their code — never your individual data (see the Privacy Policy).

7. Right of withdrawal (consumers)

You have the right to withdraw from a credit-pack purchase within 14 days without giving reasons, by a clear declaration to us (e.g. email to contact@korrektcode.de); you may use the model withdrawal form below but need not. The period starts on the day of contract conclusion. If you asked us to make credits available immediately and you withdraw, we refund the purchase price minus the proportional value of credits already spent, within 14 days using the original payment method.

Model withdrawal form: "To KorrektWort, Mohammad Mirzakhanidehkordi, Scharrnstraße 2, 38100 Braunschweig, contact@korrektcode.de: I hereby withdraw from my contract for the purchase of the following credit pack: [pack, purchase date], [your name and email used in the Service], [date]."

8. Changes, availability, and discontinuation

• KorrektWort is a young, actively developed product. We may modify features where necessary for (a) adaptation to new technical environments or increased usage, (b) security, (c) legal or regulatory requirements, or (d) further development of the Service, at no extra cost to you. If a change more than insignificantly impairs your access to or use of paid features, we will inform you in advance and you may terminate free of charge within 30 days; unused purchased credits are then refunded pro rata at the price you paid.
• We aim for high availability but do not guarantee uninterrupted, error-free operation (maintenance, outages of upstream providers, force majeure).
• We may discontinue the Service (entirely or in your country). If we do, we will give you at least 30 days' advance notice by email to your sign-in address or in the app (shorter only where required by law or compelling technical/legal reasons), keep your data export available during that period, and refund unused purchased credits pro rata at the price you paid. The free tier may be changed or ended at any time.
• You can stop using the Service and delete your account at any time on the Account page.

9. Termination for cause

We may suspend or terminate your account for good cause, e.g. serious or repeated breach of these terms, unlawful use, abuse of the AI features, or payment fraud. Where appropriate we will warn you first. On termination for good cause, remaining free credits lapse; for unused purchased credits, statutory rules on refunds and our claims for damages remain unaffected. Statutory rights to extraordinary termination remain unaffected for both sides.

10. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body, or health, and under mandatory statutory liability (e.g. product liability). For slight negligence we are liable only for breach of essential contractual duties (duties whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you regularly rely and may rely), limited to the foreseeable damage typical for this kind of contract. Otherwise liability for slight negligence is excluded.

11. Changes to these terms

We may change these terms without your consent only where the change is purely to your benefit or is required by law, court, or regulatory decision; such changes take effect after notice in the app or by email. For other material changes we will ask for your consent in the app with at least 30 days' notice. If you decline, you may continue under the existing terms until we terminate the contract with reasonable notice; unused purchased credits are then refunded pro rata at the price you paid.

12. Final provisions

We may transfer our rights and obligations under this contract to another company (e.g. in a corporate restructuring or business transfer); we will notify you at least four weeks in advance, and if you do not agree you may terminate and delete your account. German law applies, excluding the UN Convention on Contracts for the International Sale of Goods; if you are a consumer, the mandatory consumer-protection rules of your country of residence remain unaffected. We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board (§36 VSBG). Should individual provisions of these terms be invalid, the remainder stays in force.

This is a starting template and not legal advice, have it reviewed before launch.
