If your event is on All Events, it means that it is/was a ‘Public event’ on Facebook.
Whenever you create an event via Facebook, you have the option to set the privacy setting. The options would be Public, Friends of Guest and Invite-Only. If it is supposed to your private event, choose any privacy option other than Public.
If you want your event to be public on Facebook and not to be posted on Allevents.in, feel free to drop an email at ‘contact@allevents.in’. We will make sure that none of your future events get posted.
