You can use the webapp as a guest user. However, those sessions are tied to your device and are temporary (30 days long). By signing up, you will be able to:
Emails notifications can be enabled or disabled in your settings at any time.
If you want to obtain a new temporary session, you can simply delete the webapp cookies in your browser.
Cookies are a tool to store information on your computer that a website can read and write when you visit. We use them (1) to store your session information (so you don't have to log in every time you visit), (2) to save your preferences (piece style, move format, etc.) Cookies are also communicated to the server on requests but this information is not stored. Those cookies expire after 400 days (which is the maximum allowed). They are listed under the "Necessary" category in the cookie consent banner (or the cookies icon once you have accepted or refused).
You can easily find information online about how to list, visualize and delete cookies in your browser.
We also use Google Analytics (to get information about visitors) and Google Ads (to bring more traffic). Those tools also add their own cookies. Google Analytics is not that useful, so we might very well ditch it in the future - and we hope that some day we will have enough activity to get rid of Google Ads as well.
The YouTube videos embedded in the website also bring cookies (meaning for example that embedded videos you watch on this website will also appear in your YouTube history, if you have a YouTube account).
The annoying banner at the bottom of the page is from a third-party and is mandatory if we want to continue using Google Ads by complying with the GDPR and other privacy laws around the world.
Cookies are controversial because they potentially enable Google to track your activity online (since most websites use those tools, Google can track your browsing history, even if you don't use the Google search engine). By refusing the cookies in the banner, you prevent Google from adding elephantchess to the navigation history they associate with your customer profile (or more generally from collecting data about what you do on elephantchess).
On the other hand, the cookies added by elephantchess can not be used to track you outside the website.
One way to reduce and/or monitor tracking is to install Ghostery in your browser. You can also use I don't care about cookies to just automatically ignore those banners. To name just a few such tools.
We keep track of your session information (like the IP) to get information about where our users come from and when they were last online (which is required for some functionalities). It is planned to add functionality to list and delete your session data in your settings.
We don't share your information (like your email or your activity) with anyone.
