Private files and messages, encrypted on your iPhone. OneCryption is an offline encryption tool for people who prefer to exchange secret keys in person. It does not operate a message-delivery network: you choose how to send the encrypted result. HOW IT WORKS 1. Meet your contact and confirm their identity. 2. Generate shared secret key material and transfer it directly between nearby devices. 3. Write a message or select content, encrypt it locally, and share the encrypted result through a channel you choose. 4. The recipient decrypts it with the matching shared key. YOUR KEYS, YOUR CONTROL - Encrypt and decrypt text, photos, videos, audio and files. - Manage contacts and shared keys on your device. - See how much key material remains and exchange a fresh key when needed. - Use local encryption without a OneCryption messaging account. OneCryption uses a one-time-pad workflow. Key material must remain secret and must never be reused. Protect the devices and the key exchange. The channel you use to deliver encrypted content has its own privacy and metadata implications; encryption does not make a compromised device safe. FREE AND PREMIUM Text encryption is available for free. Some media and file features require Premium. Purchase options and current prices are shown in the app. If you choose a subscription, it renews automatically unless you cancel it in your App Store account settings.

AUTHENTICATE BY K-DAWGG CONNECT Your Security. Your Device. Your Privacy. Authenticate is a two-factor authentication (2FA) app built by someone in their mid-20s who's disgusted by companies profiting from user data. This isn't a corporate product designed to extract value from you—it's honest security software built by a regular person who values privacy as much as you do. No ads, no tracking, no monetization. Just straightforward 2FA protection that respects you. WHY AUTHENTICATE IS DIFFERENT Most authenticator apps are built by companies looking to monetize your data or upsell you on premium features. Authenticate takes a different approach: your 2FA codes are encrypted with military-grade AES-256-GCM encryption and stored exclusively on YOUR device. No cloud servers, no data collection, no analytics tracking, no corporate surveillance. Your security codes never leave your phone, and nobody—including the developer—can access them. This app makes zero profit. There's no business model, no venture capital, no exit strategy. It exists because someone got fed up with privacy-invasive apps and decided to build something better. If you're tired of being treated like a product instead of a person, Authenticate is for you. POWERFUL FEATURES, ZERO COMPROMISES • Scan QR codes instantly with your camera or import from your photo library • Generate standard 6-digit TOTP codes that work with all major services • Automatic 30-second code refresh with visual countdown timer • One-tap code copying with haptic feedback • Clean, modern interface with distinctive K-Dawgg Connect branding • Manual account entry for services that don't provide QR codes • Edit and manage your accounts with ease • Secure local storage with AES-256-GCM encryption • Optional PIN or biometric authentication to protect your codes • Works completely offline—no internet connection required BUILT FOR REAL PEOPLE Authenticate supports all major services including Google, Microsoft, GitHub, Facebook, Twitter, Amazon, Dropbox, and thousands more. The interface is designed to be fast and intuitive—scan a QR code, and you're done. No complicated setup, no account creation, no permissions beyond what's absolutely necessary. The app features a bold black, cyan, and magenta color scheme that's easy on the eyes and distinctly recognizable. Smooth animations and thoughtful design details make managing your 2FA codes feel effortless rather than tedious. THE K-DAWGG CONNECT PROMISE Your security and privacy will always come first. No compromises, no exceptions, no corporate BS. This is software built by someone who understands what it's like to feel frustrated by apps that don't respect you. Authenticate will never sell your data, serve you ads, or try to upsell you on premium features because there's nothing to sell—your privacy isn't for sale. If you believe software should serve users instead of exploiting them, give Authenticate a try. It's the 2FA app you'd build for yourself if you had the time. TECHNICAL DETAILS • TOTP (Time-based One-Time Password) algorithm • SHA1 HMAC with Base32 secret key encoding • Standard 6-digit codes with 30-second refresh • AES-256-GCM encryption for local storage • Compatible with OTPAuth URL format • No network access required—fully offline operation • Supports iPhone and iPad SUPPORT & CONTACT Questions, feedback, or concerns?
