Continuity planning, simplified
Words delivered
when you can't be.
What would you want your family to know if you suddenly couldn't tell them? Account passwords. Insurance details. A message you never got around to saying. JustInCaseNote holds your private notes and delivers them to the people you choose — but only if you go silent.
- Zero-knowledge encryption
- You're warned first, always
How it works
Four steps. That's it.
Write a note
Capture the things that matter — passwords, instructions, or just the words you want said.
Choose recipients
Pick who receives your note by email. They won't know until it's delivered.
Set a delivery window
Days, weeks, or months. Check in with a single tap to keep your notes held.
Silence triggers delivery
If you stop checking in and the timer runs out, your notes are delivered automatically.
Checking in
Check in however fits your day.
Staying covered is effortless. Pick whichever is closest to hand — either resets your delivery timer instantly.
Tap the button in any reminder
Every push, email, and SMS reminder includes a one-tap check-in link. No login hunt, no menu diving — you're covered in a second, wherever you are.
Open the app and tap Check In
Launching JustInCaseNote resets your delivery timer automatically. Or tap the big teal button on the home screen for an explicit check-in — same effect.
Some things even we shouldn't see.
For sensitive content like passwords or financial details, encrypt your notes with a passphrase. Your notes are encrypted on your device before they ever reach our servers — we can never read them. Only someone who knows the passphrase can unlock the note.
Encrypted on your device
Your passphrase never leaves your phone.
We only store ciphertext
Even our servers see scrambled bytes — nothing readable.
Recipient unlocks with the passphrase
Share it through a channel you trust, separate from the note.
True zero-knowledge. We literally cannot decrypt your content, even if compelled to.
We'll never send your notes
without warning you first.
JustInCaseNote sends daily check-in reminders, hourly alerts as your deadline approaches, and a final notification 30 minutes before delivery — so accidental delivery never happens.
- Daily
Gentle check-in reminders
While your timer has time to spare.
- Hourly
Closer to the deadline
Once your note has less than 12 hours remaining.
- 30 min
Final warning before delivery
One last chance to check in. Then — and only then — we send.
Reminder channels
Built for trust
The fundamentals, done right.
Beyond encryption and reminders, JustInCaseNote is built on the basics you'd expect from anything holding your most private words.
Silence-based triggering
Notes are released only after a period of silence — no manual intervention needed.
Secure delivery
Time-limited, hashed links ensure only intended recipients can view your notes.
Full audit trail
Every check-in, reminder, and delivery is logged with timestamps for complete transparency.
Who it's for
A safety net for life's what-ifs.
Parents
Protect your family
Store household passwords, insurance details, and account access so your partner is never left guessing.
Solo travelers
Travel with peace of mind
Leave instructions for loved ones while you're abroad. If something happens, they'll know what to do.
Business owners
Safeguard critical knowledge
Document what your co-founder or team would need — logins, contacts, processes — if you're suddenly unreachable.
Anyone
Say what matters
Some messages are too important to leave unsaid. Write them now, let us deliver them if the time comes.
