Encrypted notes that only you can read. hYYa Encrypted Notes is a private notepad, diary and journal for iPhone, iPad and Mac. Every note is encrypted on your device before it is saved. There is no hYYa account to create and no hYYa server to hold a copy, so your notes stay yours alone. Your notes. Your iCloud. Your Google Drive. FOR YOUR EYES ONLY ⢠Encrypted on your device, so only you can read your notes. ⢠Titles and folder names stay private too, not just what you write. ⢠Opens with Face ID or Touch ID. ⢠Find anything in seconds, and your notes stay private while you search. SYNC ON ALL YOUR DEVICES ⢠Through your own iCloud Drive, across your iPhone, iPad and Mac. ⢠Through your own Google Drive too, to reach your other devices. Only you can read what's there. ⢠Or keep your notes on this device only. Writing, search and export all work offline. ⢠Edits from two devices are merged back together, and if a note changes in two places at once, both versions are kept. Nothing you typed is ever silently discarded. WRITE THE WAY YOU THINK ⢠Headings, bold, lists and checklists appear as you type. ⢠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 ads.
