Protecting your personal and confidential information since 2009, Krypton is the first, simplest and most reliable App on the iOS Store to strongly encrypt entire documents and folders. Now also available on the macOS App Store. Your stuff is secure from prying eyes no matter where you are in the world. Metaphorically, Krypton keeps your encrypted items in a special vault, with each item contained in their own deposit box; to gain access to an encrypted item the vault must be open and the passcode key must be used to unlock the deposit box before you can discern the plaintext contents inside. In iOS the vault may be open or closed, while on macOS the vault opens upon Log In. Because the unit of encryption is an entire document or folder, Krypton is not a password manager in the traditional sense, although you can maintain a document of all your passwords that you encrypt between uses. Krypton can encrypt any type of document, including but not limited to: • Pictures and movies from your photo album. • Email messages from your mailbox. • Songs, PDFs, movies, Zip files, word processing documents, text files, images, program source code or any other object that you can download over the network or from your personal web server. • Anything on the iOS pasteboard. • Any document other Apps are willing to Share, such as Pages, Numbers and Keynote. • iCloud Drive and Dropbox files for easy cloud synchronization. Krypton uses strong encryption on each item. This has several ramifications: • If your passcode is strong enough to withstand a brute force attack, no one is going to see your stuff. • If you forget your passcode, no one can recover your stuff for you! But only that one document is lost, not your entire collection of items. • Your stuff is secure even if your iDevice or Mac is stolen, or iCloud Drive or Dropbox account is compromised.

NOTHING TO INSTALL ON THE COMPUTER. THAT IS THE WHOLE IDEA. ShareMe turns your iPhone into a small web page. Open the browser that is already on your Windows PC, Mac, Linux machine or tablet, type in the address ShareMe shows you, and you are looking at your phone. No software on that computer. No cable. No account. No cloud. HOW WEB SHARE WORKS 1. Tap Web Share on the iPhone. It shows an address such as http://192.168.1.6 2. Type that address into the browser on your computer. Use http, not https. 3. The iPhone asks you to accept. Tap Accept. 4. Browse the phone's photos, videos, music and documents in the browser and download them at original size - or drag files from your desktop onto the page to send them to the iPhone. Both directions, one page, any computer where you are allowed to open a browser. Useful on a work machine where you cannot install anything. No Wi-Fi network in the room? Turn on Personal Hotspot, join it from the computer, and Web Share works exactly the same. IPHONE TO IPHONE, WITH NO INTERNET AT ALL Both phones need ShareMe. After that there is no router, no mobile data and no internet connection involved - only the Wi-Fi or Bluetooth radio being switched on. Photos, videos, music, contacts (.vcf) and documents (PDF, DOC, PPT, XLS, ZIP) move straight from one phone to the other. - The two phones find each other on their own. No QR code, no pairing code, no sign-in. - Received photos and videos save straight into your Photos app. - Preview everything that arrived inside the app, and swipe to delete what you do not want. - Cancel a transfer from either side, at any moment. FULL SIZE. NOT A COPY OF A COPY. Nothing is compressed and nothing is resized. A 4K video arrives as the same 4K video. Multi-gigabyte files are fine. Whole camera rolls are fine. WHAT IS FREE AND WHAT IS NOT iPhone-to-iPhone transfer is free and unlimited. Web Share gives you 2 free sessions; after that it needs a subscription. We are telling you here rather than after you install. The subscription is offered weekly, monthly or yearly, and the exact price in your currency is shown in the app before you buy anything. ShareMe is free to download and is supported by ads. PRIVACY Files travel from your device to the other device across your own local network. There is no ShareMe server in the middle, no cloud storage, no account and no sign-up. Nothing is uploaded anywhere, and nothing is kept after the transfer. WHAT SHAREME DOES NOT DO Better you know now than after installing: - No iPhone to Android, and no Android to iPhone. - No cloud storage and no online backup. - No USB or cable transfer. - No NAS, SMB or printing. TIPS THAT SAVE PEOPLE TIME - Put http:// in front of the address. Browsers assume https, and https will not connect. - Keep the phone and the computer on the same Wi-Fi, or use Personal Hotspot. - Keep ShareMe open on screen while a transfer is running. - If a phone does not appear, make sure both phones have ShareMe open on the transfer screen. SUBSCRIPTION TERMS Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours of the end of that period. You can manage or cancel a subscription in your Apple Account settings after purchase.
