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.

ABSOLUTE PRIVACY: YOUR DATA IS ONLY YOURS Unlike standard security apps on the market, SUYLEX NEVER saves, stores, or keeps the email addresses or passwords you enter during scans on its servers. Thanks to cryptographic K-Anonymity algorithms, your searches are conducted completely anonymously and encrypted (hash). Once the query is finished, everything is deleted from your device. Even we cannot see what you search for! IDENTITY AND BREACH MONITOR Instantly see if your passwords or email accounts have been leaked by cybercriminals in the past. Searches across billions of rows of global cybercrime records are completed in total privacy, without your real data ever leaving your device. AUTOMATIC LEAK RADAR (24/7 PROTECTION) Your protection continues even when you close the app! The email accounts you add are automatically audited in the background at your specified intervals. The moment a new data breach involving your information occurs in the cyber world, you are instantly warned via the smart notification system. Learn about threats before they cause damage. DEVICE HEALTH AND NIST AUDIT Could your phone's operating system be manipulated? We test your device's core security using international NIST cybersecurity standards. Verify your device integrity by detecting hidden Root/Jailbreak access, modified malicious apps, and security vulnerabilities. DIGITAL FOOTPRINT AND NETWORK SECURITY Calculate how much privacy risk your social media habits pose to your profile with the "Digital Footprint Score". Additionally, instantly audit the encryption strength and cyberattack (DNS poisoning, etc.) risks of the public Wi-Fi networks you connect to. PROFESSIONAL SECURITY REPORT (PDF) Turn all your security scan results into a detailed PDF report with a single tap. With this report, which takes an X-ray of your device, you can concretely see your system vulnerabilities, leak status, and action plan.
