CarrierPony: PGP Chat & Files
Encrypted messages & files
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Private conversations built on OpenPGP. Every message and file is encrypted and signed on your device. No accounts, no analytics, nothing to read but what you send.
CarrierPony is an encrypted messenger and file transfer app for people who'd rather the middle know nothing.
Send messages and send real files, both sealed the same way. Everything is encrypted on your device and signed by your key, so only the person you paired with can open it, and they can be sure it really came from you. There's no account, no email, and no phone number. Your identity is a key that's generated on your iPhone and never leaves it.
MESSAGES AND FILES, SEALED
Chat privately and move files up to 50 MB in the same conversation, protected with OpenPGP using modern Ed25519 and Curve25519 keys. A dedicated Files tab keeps every transfer in one place, so sending a document is as simple as sending a message.
THE RELAY KNOWS NOTHING
So your messages and files arrive even when your phone is off, they pass through a relay. That relay only ever forwards sealed envelopes. No names, no message contents, no files it can open, no plaintext. It holds an encrypted blob just long enough to deliver it, then lets it go.
PAIR, THEN VERIFY
Connect by swapping an invite in person or over any channel you trust. Compare a safety number to be certain no one slipped into the middle. Give any contact a private name only you see.
YOURS TO KEEP
Keys are generated on your device and never leave it.
Lock the app behind Face ID.
Export an encrypted backup only you can open.
Already have an OpenPGP key from GnuPG or another tool? Import it and keep your identity.
OPEN AT THE CORE
The cryptography is built on PGPonyCore, published as open source under Apache-2.0. The important part isn't a secret.
FREE
No ads. No trackers. Nothing about you is collected or sold.
CarrierPony is made by NorseHorse, an independent developer.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Invites keep working after you close the invite screen. Create an invite, send it over any channel you trust, and go about your day. When the other person accepts, even hours later, they show up in your contacts the next time the app checks in, and their first messages arrive right along with them.
The invite screen now also shows how long your invite lasts before it expires.
