What we collect, in full

No cookies. Not one. If you pick a colour scheme, that choice — light, dark or system — is kept by your own browser and never leaves it: it is not sent with your requests and we never see it. Clearing your site data costs you nothing but the preference.

Counting visits, without following you. When analytics are running we use PostHog on EU infrastructure, in cookieless mode: no identifier is stored on your device, nothing persists between visits, and session replay, autocapture and surveys are all switched off. It tells us which pages people read. It cannot tell us who you are.

Errors. When something breaks, the stack trace is reported so it can be fixed. Those reports carry no name, no address and nothing you typed.

What you send us. If you submit an event or report a wrong listing, we keep your message, the link it is about, and your email address if you gave one — which is optional, and only ever used to reply. Nothing is sold, shared or handed to an advertiser, because there is no advertiser.

The listings themselves are public information: an event, its organiser, its date, its city, taken from the pages organisers publish. If you organise one of them and want it changed or removed, ask and it is done.

Write to hello@hackalendar.com for a copy of anything we hold about you, or to have it deleted. No form, no account, no waiting on a ticket queue.
