These terms apply to the use of the language learning application Davaigo, offered by Manuel Killert, Geschwister-Scholl-Straße 27, 49610 Quakenbrück ('we'). You are the contracting party as the user.
Davaigo is an application for learning Russian with guided lessons, a vocabulary trainer, listening comprehension exercises, and a library with videos, songs, and e-books. Some content is generated with the help of artificial intelligence.
Davaigo is a learning offer, not a teaching service or exam preparation with guaranteed results. We do not owe a specific learning success.
An account is required to use the service. You must be at least 16 years old; younger users need parental consent. Keep your password secret and do not share your account.
All learning features are available for free. Premium unlocks AI tools without daily limits: unlimited vocabulary lists and e-books, as well as statistics on your progress.
The applicable price will be displayed to you before purchase in the app, along with the billing period. All prices include statutory VAT. The price shown during the ordering process is decisive.
By creating an account, a free usage contract is established. A Premium contract is established when you complete the ordering process via our payment service provider Stripe. We will confirm the contract to you by email.
The monthly subscription runs for one month and is automatically renewed for another month unless you cancel it by the end of the term. The annual subscription runs for one year and is renewed for one month after the first year (§ 312k BGB). The one-time purchase has no term.
You can cancel at any time under “More → Manage Subscription” – without reason and without notice until the end of the current period. You can terminate the free account at any time under “More → Delete Account”.
You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of the contract conclusion.
To exercise your right of withdrawal, you must inform us – Manuel Killert, Geschwister-Scholl-Straße 27, 49610 Quakenbrück, lernen@davaigo.de – by means of a clear statement (e.g., by email) of your decision. To meet the deadline, it is sufficient for you to send the communication before the withdrawal period has expired.
Consequences of Withdrawal: If you withdraw from this contract, we will reimburse all payments received from you without delay and at the latest within fourteen days from the day on which we received your withdrawal notice. We will use the same means of payment that you used for the reimbursement; you will not incur any fees for this.
Early Expiration: Your right of withdrawal expires prematurely if we have begun the service after you have expressly agreed that we begin before the withdrawal period ends and you have confirmed that you lose your right of withdrawal (§ 356 para. 5 BGB).
We partially generate vocabulary lists, additional exercises, e-books, and translations automatically. Such content may contain errors. We check them with automatic rules but cannot guarantee the accuracy of every single sentence. Do not rely solely on them for important matters.
Davaigo integrates videos from YouTube and can access Spotify upon request. The terms of the respective providers apply to these contents. We have no influence on availability and content.
Do not misuse Davaigo: no automated reading, no bypassing usage limits, no sharing of access data, no use for illegal purposes. In case of significant violations, we may suspend the account.
We strive for continuous operation but do not guarantee specific availability. Maintenance work, disruptions, and outages of third-party services may lead to interruptions. For longer outages during the Premium period, we will refund proportionately.
We are fully liable for intent and gross negligence as well as for injury to life, body, and health. For simple negligence, we are only liable for the breach of essential contractual obligations – those whose fulfillment makes the contract possible in the first place – and limited to the contract-typical, foreseeable damage. Liability under the Product Liability Act remains unaffected.
We may change these terms if there is a valid reason. We will inform you of changes at least six weeks in advance by email. If you do not object before they take effect, they are considered accepted; we will specifically point this out in the notification. If you object, we may terminate at the end of the term.
German law applies. If any provision is invalid, the remaining contract remains effective. We are not willing or obliged to participate in dispute resolution procedures before a consumer arbitration board.
