This is an agreement between you and the author of Xiaolong Sudoku. By installing the app or using xiaolong.app you accept these terms. If you don’t agree with them, please don’t use the app or the website.
Parties
Rights holder — A. V. Litvinenko, a self-employed individual (Russian professional income tax regime), the author of the Xiaolong Sudoku app and the xiaolong.app website. Contact: lialex2016@gmail.com.
User — anyone who has installed the app or uses the website.
What this agreement covers
The rights holder grants you, free of charge, a simple (non-exclusive) worldwide licence to use the Xiaolong Sudoku app and website for personal, non-commercial purposes — playing sudoku — for as long as you use them.
The app and website are free. They have no paid features, subscriptions or ads.
Account
- You can play without an account. An account is only needed to sync progress between devices.
- You sign in with a one-time code sent by email. Don’t share the code with anyone.
- You can delete your account at any time — in the app or on the website.
- The rights holder may block an account involved in hacking attempts, code guessing or other interference with the service.
What you may not do
- copy, modify or decompile the app or distribute copies of it, except where the law expressly allows;
- interfere with the server, bypass limits or create excessive load, including with automated requests;
- use the app, the website or parts of them commercially without the rights holder’s written consent.
Intellectual property
Exclusive rights to the app, the website, their design, texts, graphics and code belong to the rights holder.
Fonts and some images are used under open licences (SIL Open Font License, CC0). The App Store, Google Play and RuStore badges are trademarks of their owners.
Personal data
What data is processed and why is described in the privacy policy, which forms part of this agreement.
Liability
The app and website are provided “as is”. The rights holder does their best to keep them working, but doesn’t guarantee they are error-free or that the sync server is always available.
Since the app is free, the rights holder is not liable for indirect losses or lost game progress, except where the law expressly provides for such liability.
Changes to these terms
The rights holder may change these terms. The new version is published on this page with a new date and applies from publication. By continuing to use the app you accept the changes.
Governing law and disputes
These terms are governed by the law of the Russian Federation. Disputes are first resolved by writing to lialex2016@gmail.com; if that fails, in a court at the rights holder’s location, unless consumer protection law provides otherwise.
