Answering your questions first.

ODO (One Day Only) is a space centered around real-time topic group chats. Using random accounts and daily resetting public nicknames, you join same-language rooms or create your own topic rooms.

When entering for the first time, you can pick a language and create a random account without entering your name, phone number, or email. Existing accounts can log in with bound credentials. The onboarding process creates and saves a random account, so it is not a completely account-free service.

You create a persisting random account. Public nicknames reset daily based on UTC date; changing nicknames does not create a new account. The public nickname is a display name, not an authentication credential, and is not guaranteed to be unique.

Rooms exist for at most 24 hours from creation, and may close earlier if disbanded by host, inactivity timeout, or moderation. Closure clears room data, memberships, report evidence, and handling logs. Account, device credentials, membership, and payment info are retained independently from rooms; room closure does not mean these records are deleted.

Standard messages are delivered only in real-time with no offline history; missed messages will not be backfilled. The current device shows received messages only while the room is open.

Private rooms require a room number and password to join and do not appear in public discovery lists; hosts can also require admission approval. ODO does not provide end-to-end encryption and cannot prevent participants from taking screenshots, copying, or saving content.

You can block members, report messages, or leave the room. Hosts can mute, remove members, pause joins, or disband the room. Reports preserve necessary evidence for review, but cannot guarantee prevention of all inappropriate behavior.

We do not recommend sharing identifying info in stranger group chats. Rules restrict certain contact details and advertising links, but automated filtering cannot catch all risks; please avoid sending passwords, IDs, addresses, payment information, or private photos.
