Privacy

Event Doorbell handles people's names at a door. The whole design is built so that data disappears on its own rather than piling up. Here's exactly what's kept.

If you're a guest

You scanned a code and typed a name. Here's everything that creates:

The name you typed, your answers to the host's questions, and the times you rang.
A random token stored in your own browser so the page can show your status and let you change your answers. It identifies that one arrival and nothing else.

It's deleted when the event is — 24 hours after the event was created, or sooner if the host clears the list or ends the event. For recurring events, the guest list clears between sessions.

No account, no password, no email address, no tracking, no advertising identifiers. Your name is visible to the host and any co-hosts they've added — nobody else.

If you're a host

Your email address, because it's how you sign in.
The events you own — code, name, and when it expires.
Sign-in tokens and sessions, stored as one-way hashes. A copy of the database contains nothing that could be used to sign in as you.

Your account lasts until you ask for it to be deleted. The events inside it still expire on their own.

Session history on recurring events

Recurring events keep a short history so a host can see attendance over time. It is counts only: how many people came, how many were greeted, the average wait, and how many chose each answer. Names are never carried across, and free-text answers are reduced to how many people responded — never what they wrote. The most recent 24 sessions are kept.

What we never do

No analytics, no third-party trackers, no advertising.
No selling or sharing data. There's nobody to share it with.
No location data. The QR code knows the door; the app doesn't.
No marketing email. The only email sent is a sign-in link or a co-host invite.

Who else is involved

The site runs on Cloudflare — hosting, storage, and the email that delivers your sign-in link. Cloudflare processes requests on our behalf under their own terms. Bot protection on the sign-in form is Cloudflare Turnstile, which is designed to work without tracking people across sites.

Deleting things

An event: open its dashboard and end it. That wipes it immediately.
A guest list: "Start a new session" on a recurring event clears everyone straight away.
Your account: email hello@mattevanstech.com and it'll be removed along with the events you own.

Questions about any of this go to the same address.
