Capture your days, release your stress, and keep your secrets safe. The only online diary with true end-to-end encryption.
Whether you are capturing fleeting moments, practicing daily gratitude, or analyzing your dreams, CipherWrite is the secure diary that listens.
Make it a habit. A simple, distraction-free interface encourages you to write every day. Track your mood, log your activities, and see how your life evolves over time.
Shift your mindset. Dedicated prompts help you focus on the positive. Research shows that keeping a gratitude diary improves mental health and sleep quality.
Decrypt your subconscious. Record your dreams immediately upon waking. Our encrypted storage ensures your most private visualizations are for your eyes only.
"Dear Diary" shouldn't be public property. CipherWrite is the only online diary that offers true Zero-Knowledge Encryption. Even if our servers were compromised, your diary entries would remain an unreadable scramble of code.
How are you feeling today?
What would you tell future you?
Draft your book without distraction
We've stripped away the noise and added layers of silence. The result is a writing sanctuary that feels as private as your own mind.
Your Identity is hashed. Your words are encrypted. Not even the CipherWrite team can see what you write inside the vault.
Brainstorm ideas, check for privacy leaks, and humanize your drafts with built-in AI that respects your boundaries. Cipher Write is for writers, by writers.
Encryption happens on your device. Only you hold the keys. No corporate cloud, including CipherWrite, has access to your raw text.
Sync your work across devices using encrypted payloads. CipherWrite sync is secure, fast, and completely anonymous.
Unlike other apps, the Cipher Write encryption keys never exist on our servers. Even if we were compromised, your data remains an unreadable mist.
We don't just "encrypt" data. We built an architecture where your words are physically isolated from our server's eyes.
Encryption keys are forged in the fires of your machine. They never touch the wire.
No server logs. No metadata tracking. No search history. Your path through the vault is invisible.
Anonymity is the default state. Write for years without ever telling us who you are.
We don't sell your data. We don't use AI to profile you. We charge for a service that protects your mind.
For those beginning their private journey.
