Tired of spam and being tracked online through your personal email address? Email aliases are the solution. SimpleLogin provides you with a different anonymous email address (aka email alias) whenever you sign up for a new online service, allowing you to hide your personal email address from spammers. Emails sent to an alias are forwarded to your personal inbox. Want to reply to a forwarded email? Just hit reply and the response will be sent from your alias, keeping your personal address hidden. Not only can an alias receive emails, it can also send emails. An alias is a full-fledged email address. You can create a new alias when subscribing to a newsletter, signing up for a new account, or giving your email to someone you don't trust. If you receive spam to that address, simply disable the alias. When you give away your personal email online, there is a good chance it will end up in the hands of a spammer or hacker. SimpleLogin acts as a firewall to protect your personal inbox. Over 2 million SimpleLogin aliases have been created, making SimpleLogin one of the world’s best-known email alias services. --- Why SimpleLogin? - Generous free plan: unlike other alias services, you can create up to 10 aliases using the free plan, and there's no cap on bandwidth or the number of replies and sends. We also offer a 7day free trial of our premium service, that includes all advanced features, when you sign up. - SimpleLogin is the world’s most advanced email alias service, supporting multiple mailboxes, PGP encryption, and in-app alias management. - 100% open source and independently audited for security. SimpleLogin is verified to be secure and reliable. - Private by default. SimpleLogin forwards your emails, but does not save them. We use secure infrastructure in Switzerland, operated by Proton Mail, the world's largest encrypted email service. With a premium plan, you can: - Add your own domain and create aliases such as reddit@my-domain.com or twitter@my-domain.com. You can also enable catch-all email addresses for your domain. - If you don't have a domain, use a subdomain provided by SimpleLogin instead. - Send emails from aliases: not only can you can reply to a forwarded email, you can also initiate a new conversation from your alias. - If you have several mailboxes, you can add them into SimpleLogin and choose which one to use when creating an alias. - If your mailbox supports PGP, enable PGP on SimpleLogin, and emails will be encrypted by SimpleLogin before being forwarded to your mailbox. What others say about SimpleLogin: “SimpleLogin is a comprehensive disposable email address solution that covers just about every conceivable feature, and it’s easy to use”.

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.
