About

Private Note Encrypted

Features
Read full description

Private Note lets you send a secret message that self-destructs the moment it is read. Your message is encrypted on your device with AES-256-GCM before it ever leaves. We only ever store unreadable ciphertext — never your text or your key. The instant the recipient opens it, it is permanently deleted. No copies, anywhere. WHY PRIVATE NOTE • Zero-knowledge: our servers never see your message or your key • Read once, then gone forever — no recovery, no archive, no backup • No accounts, no phone number, no tracking, no ads • Unread messages auto-expire after 7 days • All data stored and processed in the EU (GDPR-compliant) HOW IT WORKS 1. Write your secret and choose an encryption key 2. Create a secure link — only ciphertext is uploaded 3. Share the link, and give the key separately 4. The recipient opens it once, enters the key, and the message is destroyed PERFECT FOR Passwords, API keys, access codes, private messages — anything you don't want lingering in an inbox or chat history. Reading notes others send you is always free. A Private Note Premium subscription unlocks unlimited secure-link creation. SUBSCRIPTION Private Note Premium is an auto-renewable monthly subscription. Payment is charged to your Apple Account at purchase confirmation. It renews automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in your Apple Account settings. Terms of Use: https://private-note.app/terms Privacy Policy: https://private-note.app/privacy Private Note is built on a simple principle: privacy is a right, not a feature.
