How It Works

Post anything.
Be nobody.

We stripped away every barrier between you and expression. Post text, images, videos, or audio anonymously. Create private rooms. No gatekeeping, no forms, no verification.

01

Open Oneline. Start Writing.

There's no welcome screen asking for your name. No email field. No "create your account" wall. You open Oneline and the compose box is right there — cursor blinking, waiting for you. That's it. You're in.

⚡ Post text, image, video & audio instantly
02

Post Publicly, Keep Private, or Create a Room

When you're done writing, you have two paths. Keep it Private — it's only visible to you on your device, like a personal vault. Or Share it — release it into the Social feed, where anyone can read, like, and reply. Your choice, every time.

The 72-Hour Clock Starts

The moment your post goes public, a countdown begins. 72 hours. During that time, anyone can discover it, like it, reply to it, and engage with it — all anonymously. When time is up, the post is permanently deleted from our servers. Not archived. Gone.

⏳ Permanent deletion at 72h
04

Engage — All Anonymously

Browse the Social feed. Like posts that move you. Reply with your thoughts. Start threads. Build conversations. Do all of this without ever revealing who you are — because Oneline never knows who you are in the first place.

👻 Identity never exposed
05

Join or Share a Room — Anonymously

Got a Room ID and password? Enter them to join instantly — no account, no name. Inside the room, post text freely. Only room members see the content. Your identity stays hidden from everyone, including us.

🔑 Room ID + password = text-based anonymous space
🔒

Private Mode — Your Personal Vault

Not everything is meant for the world. Private mode lets you write for yourself — process your thoughts, journal your feelings, or draft ideas without sharing them.

  • Only visible on your current device — no cloud sync
  • No account means no one can access it but you
  • No 72-hour limit — private posts last until you delete them
  • Never enters our servers — pure local-first privacy
🌐

Social Feed — Unfiltered Humanity

The Social Feed is a real-time stream of public posts from anonymous people everywhere. No algorithm curating it. No echo chamber shaping it.

  • Chronological feed — newest posts first
  • Like and reply to any post, anonymously
  • Posts disappear at 72 hours, keeping the feed fresh
  • No promoted content, no ads, no manipulation
🚪

Anonymous Rooms — Invite-Only Ghost Spaces

Rooms let you build a private, invite-only anonymous community. You control who gets in — they control nothing about their identity.

  • Set a custom room name and password when creating
  • Share the unique Room ID with anyone you want inside
  • Members join with just ID + password — no account ever
  • Post text messages anonymously inside the room
  • Only room members can see the content

Rich Media — Say More Than Words

Text is powerful, but sometimes you need more. On the public Social Feed, Oneline supports images, videos, and audio clips — all posted with zero identity attached. Note: rich media is available on the Social Feed; rooms are currently text-only.

  • Post photos, screenshots, or images anonymously
  • Share video clips without watermarks or metadata
  • Upload audio recordings or voice memos
  • All media is subject to the same 72-hour deletion rule
72h

The 72-Hour promise.

Every public post has exactly 72 hours to exist. Think of it as renting a moment in the public consciousness — then it's gone, and you're free. No permanent record. No receipts.

FAQ

Questions answered.

Can anyone find out who I am? ▾
No. We don't collect any personal information — no name, no email, no phone number. You're assigned a random session handle. We don't even permanently log IP addresses to posts. There's nothing to trace back to you.
What happens to my posts after 72 hours? ▾
Public posts are permanently deleted from our servers exactly 72 hours after posting. This is not archival, not soft-deletion — it's full removal. We don't keep copies, backups of individual posts, or deleted content.
Do private posts also get deleted after 72 hours? ▾
No. Private posts are stored only on your device and have no time limit. They persist until you manually delete them. Since they never touch our servers, the 72-hour rule doesn't apply.
Can I switch a post from private to public or vice versa? ▾
You can move a private post to public at any time — and the 72-hour countdown begins from that moment. However, once a post is public, it cannot be made private again since others may have already interacted with it.
Is Oneline really free? What's the catch? ▾
Completely free. No freemium tier, no hidden upsells. We don't sell your data (we don't have any to sell). Oneline is built on the belief that anonymous expression should be accessible to everyone without compromise.
What types of content can I post? ▾
You can post text, images, videos, and audio clips — all anonymously. No account or login is needed for any content type. All public posts, regardless of format, follow the 72-hour auto-deletion rule.
What are Anonymous Rooms? ▾
Rooms are private invite-only spaces. When you create a room, you set a custom name and a password — a unique Room ID is generated. Share that ID with others and they can join using just the ID and password, no account required. Inside the room, everyone can post text, images, video, and audio completely anonymously.
Can someone find my room without the ID and password? ▾
No. Rooms are not listed publicly anywhere. The only way to join is with both the Room ID and the correct password. There is no room directory or discovery feed — access is entirely invite-based.
Can I reply to my own posts anonymously? ▾
Yes. Since there are no accounts, Oneline can't distinguish "you" from anyone else. You can reply to any post — including your own — and no one, including us, will know the connection.

Got it. Now let's post.

You know how it works. No more reasons to wait. Your thoughts are ready — Oneline is too.
