About this app

plaintxt is anonymous, end-to-end encrypted messaging that disappears by design.

NO IDENTITY REQUIRED
• no phone number, no email, no real name
• create a temporary identity in five seconds
• identities and everything they sent self-delete

END-TO-END ENCRYPTED
• messages and files are encrypted on your device before they leave it
• the server stores ciphertext it cannot read
• your private key never leaves your device — stored encrypted by the Android Keystore, excluded from backups

GONE BY DESIGN
• messages hard-delete 60 seconds after being read, or 24 hours after sending — whichever comes first
• burn-after-read timers per conversation
• live countdowns on every expiring message

BUILT FOR REAL CONVERSATIONS
• one-time invite links, QR codes, or share through any app you already use
• encrypted photo and file sharing
• real-time delivery with typing and read indicators
• works seamlessly with plaintxt.app in any browser — same identity, same conversations, via encrypted identity transfer

PRIVATE BY ARCHITECTURE, NOT BY PROMISE
• no ads, no trackers, no third-party analytics
• notifications carry no message content — ever
• report and block controls are built into every conversation

plaintxt is free and designed for adults 18+.

What’s new

plaintxt 1.0 — first release.

• temporary identities — no phone number, no email, no name
• messages and attachments encrypted on your device before they leave it
• burn-on-read: messages self-delete after they're read

• hard delete — your data is actually gone, not archived
• same identity works at plaintxt.app in any browser

For conversations that shouldn't become permanent.
