NoteKrypt

Your thoughts, encrypted. NoteKrypt keeps your notes, passwords and reminders in one private place. Everything is encrypted on your device before it syncs, so our servers only store ciphertext: we cannot read your notes, and neither can anyone else. SECURITY BUILT FOR WHAT'S NEXT • Post-quantum sharing: every share key is sealed with hybrid ML-KEM-768 + X25519, the NIST post-quantum standard paired with a proven classic curve, so what you share today stays protected against the quantum computers of tomorrow • Your password is stretched with Argon2id, using up to 64 MiB of memory per guess, which makes brute-force attacks slow and expensive even on specialised hardware • Notes and attachments are encrypted with AES-256-GCM on your device; our servers only ever see ciphertext NOTES MADE OF BLOCKS, NOT JUST TEXT • Build each page from 25 kinds of blocks: text, headings, checklists, tables, images, files, bookmarks, reminders, passwords and more • Drag blocks to reorder them and shape the page the way you think • Start from ready-made templates, or save any page as your own template • Notebooks and smart sections keep everything organized • Works offline; changes sync when you are back online ENCRYPTED ATTACHMENTS • Attach images, PDFs and other files to any note; each one is encrypted on your device before it is uploaded • Photograph a bill and keep it with its note PASSWORDS THAT FILL THEMSELVES • A full password manager inside your notes: logins, cards and one-time codes (2FA) • iOS Password AutoFill in Safari and other apps • Passkeys on iOS 17 and later • Password and passphrase generator REMINDERS AND CALENDAR • Reminders on notes and checklist items, with repeating schedules • Notifications on your devices when something is due • Month and year calendar views SHARE AND COLLABORATE • Invite the people you choose to a note and edit it together; the content stays end-to-end encrypted • Comment on shared notes • Public links with an optional password, expiry and use limit YOUR KEYS, YOUR RECOVERY • Face ID to unlock your vault • An Emergency Kit to bring your vault to a new device • Encrypted backups you control YOUR DATA, NEVER LOCKED IN • Import from Notion, Evernote, OneNote, Markdown, Bitwarden, 1Password, TickTick and Todoist • Export your passwords in Bitwarden and 1Password formats whenever you want
