If you're not connected, we don't store any information on your device, unless you participate in an event anonymously. In this specific case we store the hash of an unique identifier for the event and participation status in your browser so that we may display participation status. Deleting this information will only stop displaying participation status in your browser.
Your <b>events</b> and <b>comments</b> are delivered to other instances that follow your own, meaning they are delivered to different instances and copies are stored there. When you delete events or comments, this is likewise delivered to these other instances. All interactions related to event features - such as joining an event - or group features - such as managing resources - are federated as well. Please keep in mind that the operators of the instance and any receiving instances may view such messages and information, and that recipients may screenshot, copy or otherwise re-share them.
