Keep your text data safe with Paranoia Text Encryption PRO, implementing the strongest encryption algorithms for true peace of mind.
• Paranoia Text Encryption PRO is a universal text encryption application for iOS (iPhone/iPad/iPod) and macOS by Paranoia Works.
• Paranoia Text Encryption ensures the safety of your notes, SMS messages, emails, social networking posts, cryptocurrency keys (seeds, mnemonics), and any other text from all unwanted readers.
• The app offers true security, encrypting data using the strongest encryption algorithms available: Threefish 1024-bit, SHACAL-2 512-bit, Paranoia C4 2048-bit (a cascade of Threefish, Serpent, AES, and SHACAL-2), Blowfish 448-bit, AES 256-bit, RC6 256-bit, Serpent 256-bit, and Twofish 256-bit ciphers.
• Simply copy and paste text to and from your favorite applications, or save it to a file for future use.
• This app does not function as a "Vault application." Instead, a password is set for the current encryption/decryption session, not for entering the app itself. You may have an unlimited number of passwords for any purpose—different files, tasks, people, etc.
• Steganography: The application offers steganographic features, allowing you to conceal text or files within a JPEG image. Two algorithms are available: J-UNIWARD (content-adaptive, minimizes visual distortion, harder to detect) and F5 (matrix encoding, efficient embedding). The selected algorithm works with your chosen symmetric cipher to create the final steganogram.
• Key Encapsulation (KEM): Securely exchange encryption passwords using the post-quantum ML-KEM mechanism (NIST FIPS 203). Two parties can establish a shared password without ever transmitting it directly, with protection against future quantum computer attacks.
◆ Differences between Free and PRO versions: The PRO version offers additional encryption algorithms, specifically Threefish 1024-bit, SHACAL-2 512-bit, and Paranoia C4 2048-bit (a cascade of Threefish–Serpent–AES–SHACAL-2). While the free version can decrypt data encrypted by these advanced algorithms, the ability to encrypt data using them is exclusive to the PRO version. The PRO version also provides a key to activate the PRO versions of our desktop applications: Paranoia File & Text Encryption for PC, Paranoia Text Encryption for PC, and S.S.E. File Encryptor for PC.
• The application is directly compatible with macOS (10.15 and later). Versions for other systems and platforms are available on the application's homepage (download section - https://paranoiaworks.mobi/download/).
• An online (web-based) version, utilizing AES and client-side JavaScript, and other utilities are available at https://pteo.paranoiaworks.mobi
Unique amongst the encryption apps I've seen on the Apple App Store. It's the session by session of text and files, with infinite number of passwords/keys, that makes this special compared to the proliferation of password managers, etc. that are out there. You also have a wide choice of encryption methods. Most of those apps are encrypted "storage safes". This is way different than that. And the level of encryption available is more than enough for most people, particularly if you use a long phrase salted with random numbers and special characters standing in for letters to generate the encrypted text. And do check out the desktop version. Where you can not only encrypt text you can create steganograms to hide your newly encrypted text. Bravo developer!
Amazing app!!
No Kings!!!
This is truly one of the most amazing and useful apps I own. It works flawlessly and provides a level of security not found in any other similar app. I also find it to be highly flexible regarding importation and exportation of data, albeit for some there may be a slight learning curve. The fact it integrates with the online versions and across multiple device platforms is very useful considering secrets may need to be shared between devices. I cannot say enough about my love of this app, and it’s a steal considering the low one-time fee.
Was Great Until...

This app was truly amazing until I discovered that it had been transferring data, presumably the private data that the app is supposed to protect, via my cellular network. Most folks that download an encryption app with “paranoia” in its name see absolutely no need whatsoever for an app to transmit data over the internet or otherwise. While I am fully aware that iOS allows me to toggle this app’s ability to communicate via cellular network, seeing that the app transferred nearly 2MB of data via cellular over about 4 weeks means I cannot trust it when connected to WiFi either. The developer could have easily siphoned my personal data (and could be siphoning yours if you’re using this app). Very rude and shady.Edit after initial developer response:Thank you for your response. Unfortunately, your claim that P.T.E. doesn’t transfer any data is untrue. According to my device’s cellular data meter, your app has indeed transferred data using my phone’s cellular connection. There are many apps on the App Store (some dealing with encryption like P.T.E. does) that do not transfer any data, thus producing no entry in cellular data settings. Not only has P.T.E. produced an entry, it has transferred 2MB of data. Perhaps this behavior is totally innocuous. Perhaps you are totally unaware. Perhaps a library you’ve incorporated is unknowingly establishing a connection. Or, perhaps you are stealing users’ data. As someone that depends on security and privacy, I cannot afford to take that gamble. Like I said, your app is fantastic, but it simply isn’t worth the risk, given your unsatisfactory explanation. Until a better explanation is offered, my review will remain a 1-star.Edit after developer edit:I am changing my review to a 5-star due to this application having proven (after an update removing the Appirater component) that it no longer transfers data via cellular network. Thank you for providing a satisfactory reason for the occurrence of network data transfer, and thank you for removing the offending component.
Developer Response
This app does not transfer any data. Images for steganography (if you use this feature) are only external data used by the application. App's data are also backed up to your iCloud (if it's enabled), but it isn't done by the app itself (it's a system feature). Any other component that could probably use network data was Appirater (already removed). If you have some concern about your security, please contact Apple directly to investigate the issue (report this application as a spyware, since that's your accusation here), we have nothing to hide.
Superior encryption app!!
da.BIGredDOG
I have no issues with the app itself. I just have one issue with family sharing. How do I share the app when the only way to get the app on my family members device is to download from the App Store which in turn will charge me anyway. Please help.
