HangWhen

Privacy Policy

HangWhen is built to collect as little as possible. Here is exactly what happens to your data.

Last updated 27 July 2026.

What we store

For an event: its name, an optional description, an optional place, the dates or weekdays chosen, the daily time window, the timezone, and an optional reply deadline.

For each person who joins: the name they typed, the time slots they marked, whether they said they are going, and any poll answers they gave. If somebody is made an organizer, we store that too.

That is all. There are no accounts and no passwords. If you set a PIN to protect your name, we store only a scrambled one-way hash of it, never the PIN itself.

Email notifications

Leaving an email on an event is optional. If you add one, it is stored only for that event and used for exactly one thing: a note when the organizer picks the time, and again if that time changes. It is never shown to other participants, never shared, and never used for anything else. You can remove it at any time from the event page, and deleting the event deletes it too.

Place suggestions

Adding a place to an event is optional, and you can always just type one. While you type, what you have typed is sent to Apple Maps to fetch suggestions, so it is covered by Apple privacy terms at that moment. We store only the final text you settle on and, if you picked a suggestion, its coordinates, so the place can link to a map. Nothing else about the lookup is kept.

Google Calendar

Connecting Google Calendar is optional. If you use it, HangWhen asks Google for one thing only: your free and busy times over the dates of the event, using the read-only availability permission. We never see your event titles, guests, locations, or notes. The access happens entirely in your browser, the result is used to pre-fill the grid, and the access token is discarded as soon as the times load. Nothing from your calendar is sent to or saved on our servers.

Who can see your response

Anyone with the event link can see the event and, for everyone who joined, their name, the times they marked, whether they said they are going, and how they voted in any poll. There is no private mode: the link is the key, so keep it with the people you want to schedule with.

While your name is on an event, other people looking at the same page at the same time can see that you are there too. That is live only and is never written down.

Whoever created the event can also make other people organizers. An organizer can edit the event, pick the time, and run polls. Only the person who created it can delete it. We do not sell data, run ads, or share anything with third parties.

Analytics

We use PostHog to count page views so we can see which parts of HangWhen get used. It is served through our own domain rather than a third-party one, and it stores an identifier in your browser so that repeat visits are not counted twice. We do not use it to build advertising profiles, and event names, the names people type, and their availability are not sent to it.

Removing an event

Events are meant to be short-lived. Whoever created an event can delete it themselves at any time, using the Delete button on the event page. Deleting is permanent and takes everything with it: every name, the times people marked, any polls and their votes, and any email addresses left for notifications.

If you did not create the event, ask the person who did. They are the one holding the admin link, and it is their event to remove.

If you cannot reach them, or you want your own name and availability taken off an event that somebody else made, send us the event link through our contact form and we will take care of it.
