Stellar Private Notes — Secure, Zero-Knowledge Note-Taking
Stellar Private Notes is a secure, end-to-end encrypted note-taking app built for people who value privacy above everything. Your notes are encrypted on your device with cryptographic keys only you control — not us, not the cloud provider, not anyone else.
No tracking, no analytics, no ads, no profiling.
Just pure privacy.
🔐 True End-to-End Encryption (E2EE)
Every note is encrypted using modern AES-256-GCM and PBKDF2 before it ever leaves your device. Only you hold the keys — even if our servers were compromised, your data stays unreadable.
☁️ Private Cloud Sync (Optional)
Sync notes between your phone, tablet, and desktop — without ever exposing your content.
All syncing is end-to-end encrypted using your master key.
🔒 Local App Lock (Optional)
Add an extra layer of protection with an app-level password.
Your encryption keys remain sealed and inaccessible until you unlock.
