The app and publisher#

These terms cover the Android application Learn Bulgarian: Speak & Read (Home Screen name Learn BG, package com.zydeno.learnbulgarian), published by Andrii Matiushev, trading as Zydeno. Please read them together with the Privacy Policy. The app is available without an account, advertising, subscriptions or in-app purchases.

Educational purpose#

Lessons, grammar notes, dictionary entries, exercises, tests and cultural material are learning aids. Language use varies by context, region and speaker. Some dictionary translations and examples are machine-generated drafts; the app labels unverified translations. Model audio includes contributed recordings and synthesised speech. On-device speech recognition can make mistakes.

Practice tests, placement results and course-completion images are not official examinations, recognised qualifications or professional assessments. Zydeno is not affiliated with a government body or examination institution. Medical, administrative and other real-life vocabulary is for language practice and is not medical, legal or other professional advice. Verify important information with the appropriate professional or institution.

Use and availability#

You may install and use the app for personal language learning and ordinary educational use. Do not use the app unlawfully, misrepresent its practice results as official qualifications, or remove required credit and licence notices when reusing third-party material. Individual components may permit broader reuse under their own licences.

The course, dictionary and bundled audio work offline. Optional system voice and local speech-feedback availability depend on your Android device and installed language support. Microphone and notification permission are optional. Keep a progress export if you need a recoverable copy: uninstalling, resetting data or losing a device may remove local progress. The app does not provide automatic cloud synchronisation.

Credits and licences#

The app's original code, design and original learning material are owned by the publisher or respective authors. Sofia Sans fonts are licensed under SIL Open Font License 1.1. Dictionary material includes Wiktionary and WikDict-derived entries; examples may include Tatoeba contributions. Illustrations and audio have their respective third-party licences and attribution. The full source-specific credit list is included in the app under Credits and licences. Applicable open licences govern those components and take precedence over inconsistent restrictions in these terms.

Accuracy and responsibility#

We aim to keep the app useful and accurate, but cannot promise that every translation, audio clip, exercise or device combination is error-free, or guarantee learning outcomes. To the extent permitted by applicable law, the app is provided as available without additional warranties. These terms do not exclude rights, remedies or responsibilities that cannot lawfully be excluded, including mandatory consumer rights.

Google Play and other services#

Google Play and Android are operated by Google and other platform providers under their own terms. External websites, keyboards, document providers and sharing destinations are separate services. The publisher is responsible for this app's content and support. Google is not the publisher of the app.

Updates and contact#

Features and learning content may be updated, and updated terms will be published here with a new effective date. For help, mistakes in content or questions about these terms, contact [email protected].
