The settings are remembered by the browser, and it will only remember it as long as your privacy settings allow. For example if you go and clear all your cookies in settings, it will erase all storage used by Construct, including settings. ("Cookies" is a really bad term for this, it really means "local storage".) So you probably need to check your browser privacy settings, or if you have something like a browser extension that clears cookies every 24 hours "to improve privacy", then that will be wiping all of Construct's remembered settings too.
