Invisible-ink eliminates unauthorized access to your communications, ensuring that ONLY YOU can view and send your messages. Invisible-ink protects your business, employees, clients, intellectual property, and your reputation from spying eyes and hackers. Discuss confidential matters and share private documents with recipients around the world with the confidence that your communication is safe, secure, private, and only accessed by those that are authenticated. True FYEO — For Your Eyes Only. Private documents, messages, and images shared on invisible-ink, or [i-i] for short, are not visible to any unauthorized users. You are the only person that can see your communications. Communications stay invisible to unauthorized users. Privacy You Can See! - Powered by patent-pending PUA (Persistent User Authentication), [i-i] authenticates (persistently) the face in front of the screen and only shows the contents in real-time when it sees your eyes. If the authenticated face leaves the screen or another face appears, the contents on the screen disappear. - [i-i] allows you to communicate digitally with the same privacy and security as having a face-to-face conversation. We call the digital version of face-to-face “eye-to-eye” or [i-i]. Second Face Detection: - If a second face appears over your shoulder when you are viewing in private, the screen will obfuscate. SECURELY SHARE DOCUMENTS WITH PEACE OF MIND Security You Can Trust! [i-i] Document Exchange: - When a document is received you have the certainty and peace of mind that the document could only have been sent by one (authenticated) person, and conversely, when you send a document, you know only one person can view it. - Secure your business documents and clients’ private information. Encrypted at-rest: - Our application maintains your communication encrypted when it arrives on your device. Other applications only encrypt between devices. Our encryption only decrypts real-time when the authenticated face is looking at the screen. Custom Sharing Preferences: - When sending documents, images, or videos you decide if the recipient can export or save what you send. Maintain ownership of what you send, even after it leaves your phone. ADDITIONAL SECURITY & PRIVACY FEATURES: Military Grade Encryption: - Your communication is safe with military-grade end-to-end AES-256 encryption. Self-Destruct: - Choose how long a message is visible to recipients in the conversation, from 1 second to 1 week. - Once the message is opened, the timer starts and deletes once it goes off. Screenshot Notification: - If a screenshot is taken you will get notified who took it and when. Message Redaction: - You can delete your messages for you and for everyone in the conversation at any point. PUA Settings: - You can change the number of faces allowed, how often the PUA authentication is triggered, and how long your eyes can be off-screen before blocking the screens’ content. Metadata: - We give you the ability to share or not share your metadata with your recipients. You hold your keys: - We don’t have your encryption keys. They are locally stored on your device and never stored in our servers. WE VALUE AND RESPECT YOUR PRIVACY: We Take Your Privacy and Security Seriously. - We do not save or backup your data unless you opt-in. - We can’t view or decrypt your messages. - Keys are generated locally and stay locally in the device. - We believe in “ownership” and believe you are the owner of your data and communications. - Your messages just like your phone are yours. The way you are the owner of the phone, you should be the owner of your messages. - We don’t store your messages unless you want us to: In our [i-i] Servers or in your iCloud (the messages go from your phone to your iCloud.) They remain encrypted.

There is another app that seems similar that goes by a different name that I can find some info on and it seems to work fairly well. But I-I seems to be lacking info on the web. Sorry I rated it 3 stars because I couldn’t post without a rating. ### 5/5 — Works like a dream! *2021-10-16* Perfect! ### 5/5 — Game changer *2021-05-15, version 1.0.5* This app is amazing I don’t worry at all about my security anymore I feel so much relief.

Hands down the best app to download for safe and secured ### 5/5 — For my eyes only *2021-02-03, version 1.0.4* This app truly makes me feel secure, if someone else picks up my phone they can’t see my messages even if they have access to my phone. This app even keeps my information safe from prying, if I have someone behind me and the texts disappear and they can’t see anything. I have never seen an application like this. ### 5/5 — Privacy I can see *2021-02-03, version 1.0.4* This app is amazing, I deal on a daily basis with private information, this is the only app that I know that only the person I sent the information can access that information. This app also has great feature like self destruct messages and permissions settings when sending docs and pictures that let you decide if the person that receives it can share it or not. ### 5/5 — Keep text secure to the prying eye *2021-01-13, version 1.0.3* The app hide the messages when I’m looking or if someone else is looking. How cool!! ### 5/5 — Wow this cool *2020-12-08, version 1.0.2* So basically if anyone looks over my shoulder they wont read my messages. This is awesome because I take the metro everyday and it gets packed so you are always looking over your shoulder. ### 5/5 — Safest option out there! *2020-12-06, version 1.0.2* This is really the safest option BY FAR!!!
