PGP encryption for people who value their privacy. Everything runs on your device. No servers, no tracking, no compromises. WHAT IT DOES Keywave is a native iOS app for PGP encryption and decryption. Encrypt messages before you send them. Decrypt the ones you receive. Manage your keys. That's it. Everything runs locally using Protonmail's open-source gopenpgp library. Your keys never leave your phone. We can't see them even if we wanted to. CORE FEATURES • Encrypt & Decrypt Messages Swipe to switch modes. Select your keys. Tap to encrypt or decrypt. Copy the result. Done. • Generate PGP Keys Create new keypairs at 2048, 3072, or 4096-bit RSA. Optional password protection. Takes seconds. • Key Management Store unlimited keys on your device. Search by name, email, or fingerprint. Filter by public, private, expiring, or expired. Sort by name, date, type, or fingerprint. • Import Keys Open key files (.asc, .gpg, .key, .pub, .pem) from the Files app, paste from the clipboard, or share text straight into Keywave from another app. • Export Keys ASCII Armored or binary. Save to Files, share to another app, or copy to the clipboard. • Clean iOS Design Native SwiftUI. Haptic feedback. Dark by default. No clutter. WHY KEYWAVE Most PGP apps are ugly, complicated, or both. We're neither. • 100% Local Processing No servers. No cloud. No network requests at all. Everything happens on your device. • Zero Data Collection We don't collect, store, or see your data. No analytics. No tracking. No telemetry. • Open Source Foundation Built on Protonmail's battle-tested gopenpgp library. Transparent. Auditable. • iOS-Native Designed for iOS from the start. Not a port. Not a web page in a wrapper. WHO IT'S FOR • Privacy-conscious individuals • People tired of bloated encryption tools • Anyone who needs PGP without the complexity • Users who want their data to stay on their device SECURITY • Keys stored in the iOS Keychain • Password prompts for protected keys • Signature verification when you decrypt • No plaintext storage of sensitive data • Standard OpenPGP, so it works with GPG and other PGP tools WHAT IT'S NOT This isn't a messaging app. We don't send anything. We encrypt and decrypt text; you send it however you like. This isn't cloud-based. Everything stays on your device. If you want backups, export your keys yourself. This isn't for everyone. If you need someone to explain why encryption matters, we're not that app. THE FINE PRINT • Free. Every feature included. • No ads. No in-app purchases. • Requires iOS 17.6 or later • Works completely offline • Export your keys to keep your own backups Privacy isn't a feature. It's the whole point.
