Common Questions

How do I add a friend?

Search for your friend by their User ID from the Friends screen and send a request. Once they approve it, you'll be connected.

How do I share an event with friends?

When creating or editing an event, select the friends you'd like to invite. They'll receive a notification and can accept or decline from their end.

Can I change how a shared event looks on my screen?

Yes. Invited members can set their own display color and pinned status for a shared event without affecting how it appears to the owner or other members.

How do I block someone?

Open your Friends list, swipe on the user, and select "Block." You can review and unblock users anytime in Settings > Blocked Users.

How do I delete my account?

Go to Settings > Delete Account. This permanently removes all your events, friend connections, and profile data.
