If a friend sent you an invite link (or you got an email or text from PopIn), you can RSVP without ever creating an account.
The flow
Tap the link
From your email, text, or wherever the host sent it. The event page opens with the full details: date, location, who else is going (if the host shared that), what to bring.
Pick a response
Going, Maybe, or Can't make it.
Enter your name
So the host knows who you are. If the event allows plus-ones, you can add how many you're bringing.
That's it. No password, no profile, no app to install.
What PopIn stores: your first name, the email or phone the host sent the invite to, your RSVP status, and any plus-ones. That's it. We don't fingerprint your browser, track you across the web, or build a profile across events.
Reminders
You'll get an invite confirmation, an optional nudge if you don't reply, and a 24-hour reminder before the event. Any host updates (location change, time change, cancellation) reach you the same way.
Reply STOP to any SMS reminder to unsubscribe; reply HELP to learn more.
Plans changed?
Open the invite link again any time before the event. Your existing RSVP is shown; tap a different button to change it. PopIn remembers you via the link itself - no login required.
Deleting your data
Open the invite link, find Remove my RSVP at the bottom of the page, and confirm. That deletes your name, email, and RSVP history for the event.
Want to sign up later?
You can create an account with the same email or phone any time. Your existing RSVP history connects automatically.
