Hollow — Encrypted Messaging

Hollow

A private messenger — chat with your people, no email or phone number required.

Connecting…

Communities aren't end-to-end encrypted

Everything here — messages, names, membership — passes through the relay server in a form it can read. That's different from your 1:1 chats, groups, and calls, which the server can never read. Only post what you're fine with the server operator seeing.

⚠ Save This Now — It's Very Important

Write down or copy these 24 words before you do anything else. If you lose them and log out, your identity is gone for good — no password reset, no support team, nobody who can get it back for you. Not even us.

These words ARE your identity — anyone who has them can read your messages and impersonate you. Never share them, never send them over this or any chat.

Delete this identity?

This erases your identity from Hollow's server and from this device: your profile and username, friends and blocked lists, chat history backup, Feed posts, likes and follows, and your messages in communities. Communities you own go to one of their moderators, or are deleted if they have none. Your other devices are signed out.

Messages you've already sent in 1:1 and group chats stay on the other person's device. Logging in with your seed phrase again starts an empty account. This can't be undone.

This is you

⚠ Careful with this file

Files from other people can carry malware — only download this if you trust whoever sent it and were expecting a file.

⚠ You're about to leave Hollow

This link goes to an external site Hollow has no control over — only open it if you trust the link and whoever sent it.

Set a PIN

Once set, logging in on any device needs your seed phrase and this PIN. There's no reset — forget the PIN and your seed phrase alone won't get you back in.

Enter your PIN

Confirm your PIN to view your seed phrase.

Before you post

Posts on the Feed are public. Anyone on Hollow can read them, and they're stored on the relay without end-to-end encryption — so post only what you'd be fine with anyone seeing.

No nudity or sexual content. Anything sexual involving a minor is never allowed.
No harassment, threats or hate.
No one's private details — addresses, phone numbers, real names they haven't shared.
No spam, scams or pretending to be someone else.
Posts reported by several people are hidden until they're reviewed, anything breaking these rules is removed, and accounts that keep breaking them can be banned from posting.

I've read these and agree to them

Get Premium

One payment, forever. Pay with crypto and nothing is tied to you at all; pay by card and the card company sees the sale, while Hollow only ever sees the code it hands back.

Card, Apple Pay or Google Pay. You get an unlock code — Hollow never sees your card.

OR PAY WITH CRYPTO

Monero payments are private, so nobody can look yours up — your wallet proves it instead. After sending, open the transaction and copy the transaction key (Prove payment, or Get tx key). It only proves this one payment.

True end-to-end encryption

Forward secrecy, always

No email or phone, ever

Encrypted calls, peer-to-peer

Generate a brand-new cryptographic identity. No email or phone number, ever.

Restore an existing identity using its 24-word seed phrase.

By creating an identity or logging in, you agree to the Terms of Use, including zero tolerance for objectionable content and abusive users, and the Privacy Policy.

We will never ask for your information.

Why Hollow

Even messengers built around privacy — Signal, Telegram — still ask for a phone number before they'll let you in. Hollow doesn't. No email, no phone number, ever. Not because we're generous — because we never collect it in the first place.

For the curious: real ECDH key exchange, AES-GCM encryption, and forward secrecy on every message — relayed blind, never decrypted on our end.
