About

hYYa Encrypted Notes

Read full description

Encrypted notes that only you can read. hYYa Encrypted Notes is a private notepad, diary and journal for iPhone, iPad and Mac. Sync your notes through your own iCloud Drive or Google Drive, or keep them on this device only. Every note is encrypted on your device before it is saved. There is no account to create and no hYYa server to hold a copy, so your notes stay yours alone. No servers. No leaks. No compromises. ENCRYPTED BEFORE IT IS SAVED • End-to-end encryption with AES-256-GCM, through Apple's own CryptoKit, on your device. • Titles, folder names and dates are encrypted too. Anyone browsing the files sees only random identifiers. • Lock with Face ID or Touch ID, with your passcode or Mac password as the fallback. • Search the full text of every note. The search index is encrypted like the notes, so searching never leaves a readable copy behind. SYNC YOUR WAY, FREE • Through your own iCloud Drive, across your iPhone, iPad and Mac. • Through your own Google Drive as well, to reach your other devices. Your notes never leave your device unencrypted. • Or keep your notes on this device only. Writing, search and export all work offline. • Edits made on two devices are merged back together instead of one device's copy winning. If the same note changes in two places at once, both versions are kept. Nothing you typed is ever silently discarded. WRITE THE WAY YOU THINK • Live Markdown as you type: headings, bold, italic, code, strikethrough, quotes, lists and checklists, with a formatting bar when you want one. • Folders, pinned notes and colour labels. • Write in any language: Arabic paragraphs read right-to-left and English ones left-to-right, in the same note. • Attach pictures and files. Pictures show inside the note; PDFs and other files open with a tap on iPhone and iPad, or in your usual app on Mac. Every attachment is encrypted exactly like the words around it. YOUR WRITING STAYS PORTABLE • Export every note as plain Markdown, with its pictures and files beside it, whenever you like, for free. • Import from Markdown, plain text, HTML, RTF or an Evernote export. • No analytics, no tracking, no advertising identifier and no third-party SDKs. MADE FOR IPHONE, IPAD AND MAC • Native on every device, not a web wrapper. • On Mac: a full menu bar, keyboard shortcuts, printing and a proper Settings window. • On iPad: your folders in a sidebar, and drag and drop to file a note. • Dynamic Type, VoiceOver, Reduce Motion, and light and dark themes. FREE, AND HONEST ABOUT IT Keep up to 15 notes free for as long as you like, with no time limit and no trial to run out. Encryption, sync, biometric lock, import and export are free for everyone and always will be. One purchase unlocks unlimited notes on iPhone, iPad and Mac together. It is never a subscription, and nothing you have written is ever locked, hidden or taken away.
