Who Can Read My Private Writing?
Nobody can read your CipherWrite data — not hackers, not governments, not even CipherWrite employees. Here's why.
Short answer: Only you.
Here's who CANNOT read your writing on CipherWrite:
- •❌ CipherWrite employees — We use zero-knowledge encryption. We physically cannot access your data.
- •❌ Hackers — Even if our servers were breached, attackers would find only encrypted blobs that are useless without your password-derived key.
- •❌ Governments — If we receive a legal request for your data, we can only provide encrypted blobs. Without your key, they're meaningless.
- •❌ AI companies — Your data is never used for AI training, ad targeting, or analytics.
- •❌ Third parties — We don't share, sell, or expose your data to anyone.
- •Google Docs: Google employees and algorithms can read your documents
- •Notion: Stored in plaintext, accessible by employees
- •Evernote: Attempted to let employees read notes (rolled back after backlash)
Your privacy is not a setting on CipherWrite — it's the architecture. Read more about our security approach.
