About LastingNote
Your words. Delivered when they matter most.
LastingNote is a secure message platform that ensures your most important words reach the people you love — even when you can't deliver them yourself.
What is LastingNote?
LastingNote lets you write heartfelt messages, letters, and notes for the people who matter most. Your messages are stored with military-grade encryption and automatically delivered to your chosen recipients if you ever become unable to check in. Whether it's a final goodbye, words of wisdom, or a birthday message years from now — LastingNote makes sure your words are never lost.
Why LastingNote?
Military-Grade Encryption
Your messages are protected with ChaCha20-Poly1305 encryption and Argon2id key derivation — the same standards trusted by security professionals worldwide.
Dual Security Modes
Choose Guardian mode for true end-to-end encryption where even we can't read your messages, or Automatic mode for guaranteed delivery with server-managed keys.
Not Just for Emergencies
Schedule milestone messages for birthdays, anniversaries, graduations, or any future date. Messages are only delivered if you're unable to check in and the date has arrived.
7+ Ways to Check In
Check in via the iOS app, web dashboard, macOS menu bar, Windows tray, CLI, email reply, or SMS. Stay connected on your terms.
File Attachments
Attach photos, documents, and files up to 25MB per file. Include the memories and documents that matter alongside your words.
How It Works
1. Write
Compose your messages to loved ones. Add text, photos, and files. Choose your recipients and set delivery conditions.
2. Schedule
Set your check-in period and optionally schedule messages for specific milestone dates like birthdays or anniversaries.
3. Check In
Periodically confirm you're okay. Use any of 7+ methods — it takes just seconds. Miss a check-in and reminders kick in automatically.
4. Rest Easy
Your messages are safe, encrypted, and ready. If anything happens, your words will reach the right people at the right time.
Built to Last
Other services have come and gone, leaving users stranded and messages undelivered. LastingNote is built differently — with sustainable infrastructure, transparent security, and a commitment to being there when it matters most. Your words deserve a platform you can trust.
