PGPony is a free, native OpenPGP encryption app for iOS and Android with full GnuPG interoperability.

PGPony brings proper OpenPGP encryption to iOS and Android. Generate Ed25519 keys, encrypt and decrypt messages, exchange public keys via QR or WKD, and round-trip cleanly with GnuPG. No accounts, no servers, no tracking. Free, built by a solo independent developer.

PGPony is a privacy-first OpenPGP encryption app for iOS and Android, built by an independent solo developer. It fully implements OpenPGP v4 (RFC 4880) — including Ed25519 / Curve25519 key generation, encryption, signing, decryption, and verification — and adds import, decryption (AEAD-OCB), and signature verification for v6 keys (RFC 9580). Byte-exact interoperability is tested against GnuPG 2.4.x on every release. V6 key generation and encrypting to v6 recipients are coming in subsequent releases. Users can generate keys on-device, encrypt and decrypt messages, sign and verify, exchange public keys via QR codes or Web Key Directory lookup, and integrate with system-level Share Sheets on both platforms.

The app is fully free, contains no advertising, no analytics, no tracking SDKs, and no account system. Private keys never leave the device's secure enclave. Source-of-truth standards compliance is verified on every release.

PGPony is a native OpenPGP encryption application for iOS and Android, designed to bring the rigour of desktop PGP tooling (GnuPG, Thunderbird, Kleopatra) to a mobile experience that has historically been poorly served. The app fully implements OpenPGP v4 (RFC 4880) — including Ed25519 / Curve25519 key generation, encryption, signing, decryption, and verification — with modern primitives throughout: Ed25519 for signing, Curve25519 / X25519 for key agreement, AEAD-OCB for authenticated symmetric encryption, and Argon2id for password-based key derivation. PGPony additionally supports the v6 OpenPGP standard (RFC 9580) for inbound operations — importing v6 keys, decrypting v6-encrypted messages, and verifying v6 signatures. V6 key generation and encrypting to v6 recipients are planned for upcoming releases. Compatibility with GnuPG 2.4.x is byte-exact and verified on every release through an automated round-trip test suite.

Beyond the cryptographic core, PGPony emphasizes practical usability: QR-code key exchange, Web Key Directory (WKD) lookup, system Share Sheet / Intent integration, configurable auto-clearing clipboard, biometric app lock, and local key-expiration reminders. The app ships in six languages and runs identically on both platforms.

Privacy posture is structural rather than promised: PGPony operates no servers, has no account system, contains no analytics SDKs, no telemetry, and no advertising identifiers. The only network traffic is opt-in keyserver and WKD lookups, triggered only by direct user action. PGPony is developed independently by NorseHorse, a solo indie developer based in Alabama, and is offered free of charge with no in-app purchases.
