Multi-layered security
Use device biometrics for app access and a Master Passphrase for protected notes and encrypted backups.
Offline-first private notebook
Security, simplicity, peace of mind.
Krypnotes is a private digital notebook for secure notes, tasks, folders, protected content, and encrypted backups. It is designed around a zero-knowledge architecture where your personal notes stay on your device.
A complete toolbox for your thoughts
Advanced rich editor
Write with headings, lists, colors, tables, and voice dictation through device speech recognition.
Integrated to-do lists
Track tasks, completion, reminders, and daily action items inside the same private app.
Effortless organization
Use folders, pinning, sorting, and search to keep private information structured.
Customize and export
Choose themes, fonts, list/grid views, and export notes to plain text or PDF when needed.
100% offline and private
Your data lives on your device. Notes are not sent to Krypzon servers.
Your privacy is the foundation
Krypnotes is built on a zero-knowledge principle. We cannot see, analyze, sell, or recover the content of your notes because the app stores your data locally on your device.
