Terms of use

Your account

• One account per person. Keep your password to yourself; you are responsible for what is done with your account.
• Your username must not pretend to be someone else, and must not be offensive. We may change or remove a username that breaks this.
• You need to be at least 13 to make an account, or older if the law where you live requires it.

Fair play

In games against people and in rated puzzles, every move must be your own. That means:

• No chess engines, analysis tools, databases or other people helping you while you play.
• No losing on purpose to lower your rating or to raise someone else's.
• No second accounts to play yourself or to get around a ban.

Against the bots and in the daily puzzle, use whatever helps you learn. If we find unfair play, we may cancel the games, reset ratings or close the account.

How to treat other players and the site

• No harassing, threatening or insulting other players, in names or anywhere else.
• No attacks on the site: don't try to break in, overload it, or flood it with automated requests or games.
• Don't use the site to break the law.

Your games

Finished games are public, so by playing you let us store them and show them on the site, with your username. The privacy page says what else we store and how to have it deleted.

Our content

The site's design, text and original artwork are ours; please don't copy them as a whole. Parts made by others, such as the chess engine, the puzzles and some piece sets, are used under their own licences, listed in the credits.

No guarantees

Linebook is free and provided as it is. It started as a university project and is still being built: pages can break, the site can be down, and while it is young we may reset ratings or clear data, which we will try to announce first. As far as the law allows, we are not liable for losses from using the site or from it being unavailable.

Stopping

You can stop using the site whenever you like, and ask us to delete your account. We may suspend or close an account that breaks these terms.

Changes and questions

When these terms change, the date at the top changes with them, and important changes will be announced on the site first. Questions go to support@forkandknight.com.
