These terms apply to the Verbee app for Android and iOS, made by Oleg Mastriukov, an individual developer (“I”, “me”). By using the app you agree to them. The terms of the store you got the app from (Google Play or the App Store) also apply.
Verbee shows conjugations of Dutch verbs, the article (de / het), plural and diminutive of nouns, short grammar explanations and English translations. You may use it for personal learning, teaching and study.
The conjugations are generated by rules from open dictionary data, and I check them, but mistakes are possible. Verbee is a learning aid, not an official reference. For exams, legal or professional texts, check an authoritative source. You can report mistakes in the app with “Report a mistake”.
The word data comes from English Wiktionary and Dutch Wiktionary (WikiWoordenboek) contributors, extracted by kaikki.org, and from the FrequencyWords list (OpenSubtitles 2018). This data, and the data files Verbee builds from it, are licensed under Creative Commons Attribution-ShareAlike 4.0 (CC BY-SA 4.0). You may reuse that data under that licence, including commercially, as long as you credit the sources and share your adaptations under the same licence. Nothing in these terms limits those rights.
The app itself (its code, design, icon, the name “Verbee” and the grammar texts written for it) is © Oleg Mastriukov, all rights reserved, except for the data above.
Verbee is free and has no in-app purchases at the moment. If paid features are added, they will be sold through Google Play or the App Store. The store handles payment, taxes and refunds under its own terms, and your statutory rights as a consumer are not affected. A one-time purchase stays linked to the store account you bought it with.
Don’t use the app or its feedback form to send spam, abusive content or anything unlawful, and don’t try to disrupt the feedback service.
The app is provided “as is”, without warranties of any kind, to the extent the law allows. I don’t guarantee that it is error-free or always available, and I may change or stop it at any time.
To the extent the law allows, I am not liable for indirect or consequential damage, or for damage caused by mistakes in the data. Nothing in these terms limits liability that can’t be limited by law, or your rights as a consumer under the law of the country where you live.
See the privacy policy.
I may update these terms; the new version will be published on this page with a new date. These terms are governed by the law of the Netherlands, without taking away the protection of mandatory consumer law in your country.
