THE PRACTICE AGREEMENT

Terms of use

Version of 28 October 2026 · Deutsch

These terms apply when you use the LangChat app and its subscriptions. The privacy notice explains how your data is used. This website only gives information: it does not sell subscriptions or offer downloads.

Who provides LangChat

LangChat is provided by Youssef Kmaira, Youssef Kmaira Softwareentwicklung, Eichelkamp 25, 38440 Wolfsburg, Germany (“we”). Contact: support@lang-chat.com. Full provider details are in the Impressum.

Your account

LangChat is for people aged 18 or older. During setup the app asks you to confirm this; it does not ask for your date of birth. An account is for one person. Keep your sign-in details safe and do not share your account or subscription.

What LangChat offers

LangChat is an automated language-learning app. It offers flashcards and vocabulary practice, learning paths, and spoken or typed conversations with an AI conversation partner, with feedback on what you said. It does not include human teaching or marking, certificates or a guaranteed learning result. We improve the app over time and may change its content and features. The main features of a plan you pay for stay available while your subscription runs.

The AI conversation partner

The conversation partner is an AI, not a person. Its replies, corrections, translations and feedback are generated automatically and can be wrong, incomplete or unsuitable. Do not rely on them for medical, legal, financial or other important decisions. If something goes wrong, please use the report option in the app.

Do not share sensitive personal information in a conversation; invented details work just as well for practice. AI features need the AI sharing choice in the app, which names the services involved. While it is off, AI features do not work. Turning it off does not cancel your subscription. The privacy notice has the details.

Plans

LangChat has two subscriptions, each billed monthly or yearly:

• Plus: flashcards, learning paths and the AI conversation partner, with 30 minutes of talk time a day.
• Pro: everything in Plus, talk time with no daily limit under the fair-use rule below, and My scenarios, where you create your own conversation scenarios.

Daily talk time renews at midnight in your account’s time zone. Unused time does not carry over. Only active practice counts. Setup, waiting for the partner’s reply, time with the app in the background and inactivity after one minute do not count.

The price, currency, billing period and any free trial are shown in the App Store or Google Play before you buy, and they can differ by country. Some content can be tried without a subscription.

Fair use for Pro

Pro is meant for one person’s own learning, and normal use of its talk time is not limited. To protect the service from misuse, such as automated use, a shared account or resold access, Pro talk time pauses after 3 hours of active talk in one day. It is available again at midnight in your account’s time zone. Flashcards and the rest of the app stay available.

Free trial

Plus includes a 7-day free trial on monthly and yearly billing for eligible new subscribers. Pro has no free trial. The store confirms your eligibility and the trial terms before you start. During the trial you get all Plus features and Plus’s normal daily talk time.

When the trial ends, the subscription starts automatically and the store charges the price shown, unless you cancel before the trial ends. Apple asks you to cancel at least 24 hours before the end of the trial. Depending on the store, access can end straight away when you cancel during a trial.

Renewal, plan changes and cancellation

Subscriptions renew automatically for the same billing period until you cancel. Cancel through the store where you subscribed: Apple subscriptions or Google Play subscriptions. After you cancel, your plan stays active until the end of the period you have paid for. Deleting your LangChat account does not cancel the store subscription; see account deletion.

You can switch between Plus and Pro, or between monthly and yearly billing. The store decides when a switch takes effect and how any remaining paid time is credited. If you move from a Plus free trial to Pro, the free trial ends and Pro’s price applies from then, under the store’s rules for upgrades.If a price changes, the store tells you in advance and asks for your consent where required. To use a purchase on a new device, sign in with the same store account and choose Restore purchases.

Refunds and withdrawal

Payments are handled by Apple or Google. Refund requests for store purchases go through the store; see withdrawal and refunds. You can also contact us if a paid feature does not work or a purchase is missing. Your statutory rights are not affected, including your rights if the app does not work as described.

Your content and acceptable use

What you say and write stays yours. You allow us to process it to provide the features you use, as described in the privacy notice. Do not use LangChat to break the law or harm others, do not submit content that infringes other people’s rights, and do not use automated access, get around usage limits or try to gain unauthorised access. We may limit or close an account that seriously or repeatedly breaks these rules. Where possible, we tell you first and explain why.

Availability

We work to keep LangChat available, but maintenance, updates and technical problems can interrupt it at times.

Liability

We are liable without limitation for intent and gross negligence, for injury to life, body or health, and under the German Product Liability Act. For slight negligence, we are liable only for breaching an obligation that is essential to the contract and that you may rely on. That liability is limited to the damage that is typical and foreseeable for this kind of contract. Mandatory statutory liability is not affected.

Changes to these terms

We may update these terms when the app, its plans or the law change. We will tell you in the app in good time before a change affects your subscription, and you can cancel before it takes effect.

Applicable law

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer living in another country, the mandatory consumer protection of that country still applies.
