hYYa Encrypted Notes

Your notes. Actually private.

hYYa Encrypted Notes encrypts everything on your device before it is saved. Your notes open only with your phone's own unlock or your passphrase, so hYYa cannot read them, and neither can anyone without them. hYYa runs no server that could hold a copy, and there is no hYYa account to break into.

A PRIVATE NOTEPAD, DIARY AND JOURNAL
Quick memos, a private diary, a long-running journal: use it as a secure notepad or a vault for anything you would never want someone else to read. Every word is encrypted on your device and opens only for you, and it all works offline, with no internet connection needed for anything but the optional sync and the one-time purchase.

ENCRYPTED BEFORE IT IS SAVED
Every note, every title, every folder name and every date is encrypted with AES-256 before it is saved. Even the list of your note titles is encrypted, so every note the app keeps on your phone stays unreadable until you unlock it.

NO ACCOUNT TO CREATE. NO SERVER. NO TRACKING.
There is nothing to sign up for, and no hYYa server for the app to talk to, so it never sends anything to us. It contains no analytics of any kind. Apart from Google Play's own purchase screen, the only connection it makes is to your own Google Drive, and only if you switch sync on.

SYNC THROUGH YOUR OWN GOOGLE DRIVE
Optional, and it stays yours. Your library syncs as encrypted files in your own Google Drive, attachments included, and edits made on two devices are merged instead of one device's copy winning. On another phone or tablet, choose "Open My Library from Google Drive" and enter your passphrase. hYYa never sees any of it: sync sends your notes only in encrypted form, and only to the Google account you chose.

WRITE IN ANY LANGUAGE
Arabic paragraphs read right-to-left while English paragraphs in the same note read left-to-right, worked out line by line as you type, checklists included.

ATTACHMENTS, SEALED
Add images and files to a note. They are encrypted exactly like the words around them, and each one stays tied to the note it belongs to. Pictures show inside the note and PDFs open page by page in the app, with nothing decrypted written to your phone.

BRING WHAT YOU ALREADY WROTE
Import from Markdown, plain text, HTML, RTF or an Evernote export, several files at once or a whole folder; imported notes count toward your 15 free notes. Import and export are both free — an app that promises you can always leave cannot charge you for the door.

MARKDOWN, WITHOUT THE CEREMONY
Headings, bold, lists, checklists and quotes, with a toolbar when you want it and plain text underneath, so anything you export opens in any text editor, not only in this app.

SEARCH, STILL SEALED
Search titles instantly, and the full text of every note once the app has read through them. The search data is encrypted too, so searching never leaves a readable copy of your notes anywhere.

UNLOCK WITH BIOMETRICS
Your notes lock when you leave the app, and open with your fingerprint or your device's screen lock. A newly added fingerprint never locks you out, and if this device ever loses its key, your passphrase opens your library again.

FREE, AND HONEST ABOUT IT
Keep 15 notes free, forever — no clock, no countdown, no trial to expire. Encryption, sync, biometric unlock, import and export are free for everyone and always will be. A single one-time purchase lifts the note limit. It is never a subscription, and nothing you have already written is ever locked, hidden or taken away.

EXPORT WHENEVER YOU LIKE
Every note exports as a plain text file (Markdown) with its attachments beside it, free, into a folder you choose. This app exists to keep your writing portable, so holding it hostage would defeat the point.
