ChesStresS is an online chess game operated from the United Kingdom. UK GDPR and, for players in the EU, EU GDPR apply.
On your device only: your settings, level, tokens, ratings and saved games.
On our server when you play online: the nickname you choose, a random account identifier and secret key created by the app (no email address or password is collected), your ratings, token balance and titles, the moves and clock times of your online games, and technical connection data (such as IP address) that our hosting provider, Cloudflare, processes to deliver the service.
We ask for your year of birth once to check that you are 13 or older. We do not store it.
We do not sell your data or your games. We do not show advertising or use advertising trackers in this version. We do not ask for your real name.
To run the games you choose to play (performance of the service) and to keep play fair and prevent abuse (legitimate interest).
Online game records are kept while the test runs. Connection data used for fraud prevention is kept for no longer than 90 days.
You can ask for a copy of your data, for correction or for deletion, and you can object to processing. Data stored on your device is removed by deleting the app or clearing site data. Your server-side account, with its ratings and game list, can be deleted at any time in the Account tab. You can complain to the UK Information Commissioner's Office (ico.org.uk).
ChesStresS is not for children under 13.
When accounts, purchases or advertising are added, this policy will be updated before they go live.
