Terms of Service
1. Scope and provider
These terms apply to the use of “Vocabular” as an app and web app. The provider is Daniel Weidensdörfer,
Bautzner Str. 22, c/o Quartier22, 01099 Dresden, Germany. Email: hallo@danielweidensdoerfer.de.
Differing terms of users do not apply.
2. Service
Vocabular is a vocabulary learning app with flashcards. You can create card sets, add vocabulary pairs
manually and learn with them. With the AI feature, we generate language pairs from your inputs. We
currently use Google Gemini for this. The AI feature costs credits. We may also grant credits free of
charge (e.g. as a starting balance). The scope of functions may change.
3. Account
a) You need an account to use the app. You can sign in with an email address or with Google.
b) You must be at least 16 years old. If you are under 18, you confirm that your legal guardians agree
to purchases in the app.
c) Your information must be correct. Keep your login details secret and tell us if you suspect misuse of
your account.
d) An account belongs to one person. You may not transfer it.
4. Credits and prices
a) You can buy credits in the app or on the web. You see the available packages and prices before you
buy. All prices are final prices including statutory VAT.
b) Each AI generation uses credits. How many depends on the chosen size of the card set.
c) If a generation fails, we do not deduct any credits.
d) Credits are not money. They are not transferable, cannot be paid out and can only be used in
Vocabular.
e) Credits do not expire as long as your account exists.
f) When credits are used, free credits are used first. After that, purchased credits are used in the
order of purchase (oldest first).
5. Payment
a) Purchases in the app are processed through Google Play or the Apple App Store, purchases on the web
through Stripe. The terms of the respective payment service also apply. The price is due upon purchase.
Credits are added to your account after successful payment.
b) Conclusion of contract on the web: You select a credit package and are redirected to Stripe. There
you enter your payment details and can check and correct them before submitting. You can cancel the
process at any time by closing the checkout or going back. By clicking the button for the purchase with
payment obligation, you make a binding offer. We accept it by crediting the credits to your account. We
confirm the order details to you by email. We store the order details. You can access and save these
terms at any time. The contract languages are German and English.
c) Chargebacks: If a payment on the web is charged back or otherwise reversed, we may withdraw the
associated unused credits, claim back credits already used up to their value and suspend your account
until the matter is resolved. Your statutory right of withdrawal remains unaffected.
6. Right of Withdrawal
a) Purchases via Google Play or the Apple App Store: The withdrawal and refund policies of the
respective store apply.
b) Purchases on the Web (Consumers): The statutory right of withdrawal applies in accordance with our
separate Instructions on Withdrawal.
7. AI content
a) The AI can make mistakes, e.g. incorrect translations or unsuitable examples. We give no warranty for
the accuracy, completeness or suitability of the generated content. Check it yourself where needed.
b) Your inputs must not contain unlawful content and must not infringe the rights of third parties. Do
not enter personal data of third parties or sensitive data. Your inputs are transmitted to Google for
the generation (see Privacy Policy).
c) We may technically limit use of the AI feature, e.g. after repeated failed attempts, and reject
inadmissible inputs.
8. Rights in content
a) We grant you a simple, non-transferable right to use the app for your own purposes. The app,
software, design and logo remain with us.
b) Your card sets and inputs remain yours. You grant us the right to store and process them to the
extent necessary to provide the app.
c) You may freely use the generated language pairs for your learning purposes. The AI may produce
similar results for other users.
9. Permitted use
In particular, the following is not allowed: automated access (e.g. bots, scraping), circumventing
limits or protective measures, attacks on our systems, reverse engineering the app (except where
permitted by law), sharing your access and unlawful content.
10. Availability
We endeavour to keep the app available as continuously as possible. We do not owe uninterrupted
availability, e.g. due to maintenance or disruptions at third-party providers. We may change or
discontinue functions if this is reasonable for you.
11. Liability
a) We are liable without limitation for intent and gross negligence, for injury to life, body or health,
under the Product Liability Act and where we have given a guarantee.
b) In cases of simple negligence, we are only liable for the breach of essential contractual
obligations. These are obligations on whose fulfilment you regularly rely and which make the proper
performance of the contract possible in the first place. Liability is then limited to the foreseeable
damage typical for this type of contract.
c) Otherwise, liability for simple negligence is excluded. This also applies to the personal liability
of our employees and vicarious agents.
d) Your statutory rights in case of defects of digital products (Sections 327 et seq. of the German
Civil Code) remain unaffected.
12. Term, termination and suspension
a) The contract runs for an indefinite period. You can end it at any time by deleting your account in
the settings. All your card sets and learning data are then permanently deleted. Recovery is not
possible. Unused credits then expire without refund, to the extent permitted by law.
b) We may suspend or terminate your account for good cause, in particular for a breach of Section 9.
c) We may also terminate the contract with 30 days’ notice. In that case we refund the remaining value
of your purchased, unused credits. The remaining value of a package is the price actually paid for the
package, divided by the number of credits in the package, times the number of your credits from it that
have not yet been used. Discounts, promotional prices and vouchers are already taken into account.
Purchased credits are deemed used in the order of purchase (oldest first). We do not refund credits
granted free of charge.
13. Changes to these terms
We may change these terms for a material reason, e.g. a change in the law or new functions. We will
notify you of changes in advance by email or in the app. They only apply once you agree. If you do not
agree, the previous terms continue to apply. We may then terminate the contract under Section 12.
14. Data protection
How we process your data is set out in our Privacy Policy.
15. Governing law and dispute resolution
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you
are a consumer, mandatory consumer protection provisions of your country of residence remain unaffected.
If the user is a merchant, the place of jurisdiction is Dresden. We are neither willing nor obliged to
participate in dispute resolution proceedings before a consumer arbitration board.
16. Final provisions
If a provision is invalid, the remaining provisions remain valid. In case of discrepancies between
language versions, the German version prevails.
17. Additional notes for iOS app users
a) These terms are between you and us, not with Apple. We are solely responsible for the app and its
content. Apple has no obligation to provide maintenance or support for the app.
b) If the app does not conform to an applicable warranty, you may notify Apple. Apple will then refund
the purchase price of the app, if any. Beyond that, Apple has no warranty obligation for the app. We are
responsible for claims relating to defects of the app, claims under consumer protection or similar
legislation and third-party claims for infringement of intellectual property rights.
c) You represent that you are not located in a country subject to a US embargo or designated by the US
as a “terrorist supporting” country, and that you are not on any US list of prohibited or restricted
parties.
d) When using the app, comply with applicable third-party terms, e.g. those of your mobile or data plan.
e) Apple and its subsidiaries are third-party beneficiaries of these terms. Once you accept them, Apple
may enforce them against you.
