End-to-end encrypted
Messages and supported media are encrypted on your device before they are sent. The service carries encrypted content it cannot read.
A different kind of messenger
No phone number. No email. No password. Create your UserID on your device, connect with people you trust, and share what matters with end-to-end encryption.
Your identity starts with a UserID. Your recovery phrase stays with you.

Privacy starts at sign-up
Gaslight creates a UserID on your device. No phone number, email address or password is needed to get started. Add someone using their UserID or scan their QR code, then start a conversation.
Your recovery phrase is the key to restoring your identity. It stays on your device, and we cannot recover it for you.
Understand how Gaslight worksKeep the focus on the conversation. Share only what you choose to share.
Privacy is built in
The essentials are part of how Gaslight works, not a collection of switches you have to discover.
Messages and supported media are encrypted on your device before they are sent. The service carries encrypted content it cannot read.
Your device creates your Gaslight identity from a recovery phrase. No phone number, email address or password is required.
Find someone by UserID or QR code, then compare your safety numbers to verify the connection.

More than text
A good conversation isn't only words. Send images, videos, voice messages and documents in the same private space.
A little more reassurance
Every conversation has a safety number you can compare with the other person. Scan a QR code together to make checking it easier.
It is a simple way to verify that the encryption identity at each end matches.
Explore Gaslight's protectionsTake a moment to verify the person on the other side of the conversation.
Getting started
Install Gaslight. Your device creates your identity and recovery phrase. Keep the phrase somewhere safe.
Share your UserID or scan a QR code. You decide who can reach you.
Send messages, images, videos, voice messages and documents protected with end-to-end encryption.
Vanishing Mode
Turn on Vanishing Mode for a conversation. Messages older than 24 hours are removed from your device.
A reminder: Vanishing Mode cannot stop the other person from keeping a copy, for example with a screenshot.
Privacy tools should be useful and honest. See what each feature does, and what it cannot do, before you rely on it.
